Executive Summary As part of an initiative to reduce energy cost and consumption, the Evesham MUA secured the services of Camp Dresser and McKee (CDM) to perform an energy audit at their two wastewater treatment plants in an effort to develop comprehensive Energy Conservation and Retrofit Measures (ECRMs).

CDM’s energy audit team visited the facilities on July 13th 2010. As a result of the site visits and evaluation of the historical energy usage of the facilities, CDM was successful in identifying opportunities for energy savings measures.

CDM has also evaluated the potential for renewable energy technologies to be implemented at the Authority’s wastewater treatment plant facilities to offset the electrical energy usage. Specifically, the use of solar electric photovoltaic panels, ground source heat pumps and wind turbines were investigated.

In addition to identifying ECRMs and the potential for on-site energy generation, an alternate third party supplier was contacted in an effort to identify further energy cost savings available for Authority. This is discussed further in Section 5. Additionally, there is potential for the Authority to make money by participation in a Demand Response Program, as discussed in Section 5.2.

Not all ECRMs identified as a result of the energy audit are recommended. ECRMs must be economically feasible to be recommended for implementation. The feasibility of each ECRM was measured through a simple payback analysis. The simple payback period was determined after establishing Engineer’s Opinion of Probable Construction Cost estimates, O&M estimates, projected annual energy savings estimates, and the potential value of New Jersey Clean Energy rebates, or Renewable Energy Credits, if applicable. Generally, ECRMs with a payback period of 20 years or less are recommended, unless other factors such as wastewater system operational issues need to be factored into the decision process.

Historical Energy Usage The following table, Table ES-1, summarizes the historical energy usage at each of facility, for the average from January 2009 through January 2010, as presented in Section 3. These values can serve as a benchmarking tool, along with the building profile that has been established through the EPA’s Portfolio Manager Program for the wastewater treatment plant facility, to quantify the reduction in electrical energy and natural gas usage following the implementation of the recommended ECRMs.

Renewable Energy ECRMs Solar Energy Section 4.5 of the report provides for an economic evaluation of a PV solar system that was evaluated to be installed at Evesham MUA facilities. The evaluation covered the economic feasibility of the MUA installing a solar energy system under a typical construction contract and to assume full responsibility of the operation of such a system.

Based on a simple payback model, summarized in Table ES-5, it would benefit the Evesham MUA to further investigate the installation of a solar energy system at the Elmwood Treatment Plant, but not at the Woodstream Treatment Plant. This is primarily based on the initial upfront capital investment required for a solar energy system installation and the 13.3 year payback period for the Elmwood Treatment Plant, and a negative net present value (NPV) for the Woodstream Treatment Plant. This payback period may justify installing the solar energy system. Other options such as Power Purchase Agreements are potentially available as well to help finance

Wind Power Generation Section 4.3.2 of the report provides for an economic evaluation of a wind turbine energy system that is not recommended to be installed at any of the Evesham MUA Facilities, due to a payback period of greater than 20 years. The evaluation covered the economic feasibility of furnishing and installing a wind turbine energy system under a typical construction contract and to assume full responsibility of the operation of such a system.

Wind power as a renewable energy source also qualifies for Renewable Energy Certificates (REC’s). The prevailing energy market, Renewable Energy Incentive Program (REIP) and REC’s comprise the major factors influencing a wind turbine energy system installation. Other options, such as government bonds or a Power Purchase Agreement are potentially available and can assist with the financing of this project.

Figure 1-1: Energy Audit Phases

Section 1 Introduction 1.1 General As part of an initiative to reduce energy cost and consumption, the Evesham Municipal Utilities Authority (EMUA) has secured the services of Camp Dresser and McKee (CDM) to perform an energy audit for their Elmwood and Woodstream wastewater treatment plants in an effort to develop comprehensive energy conservation initiatives.

The performance of an Energy Audit requires a coordinated phased approach to identify, evaluate and recommend energy conservation and retrofit measures (ECRM). The various phases conducted under this Energy Audit included the following:

Gather preliminary data on all facilities;

Facility inspection;

Identify and evaluate potential ECRMs and evaluate renewable/distributed energy measures;

Develop the energy audit report.

Figure 1-1 is a schematic representation of the phases utilized by CDM to prepare the Energy Audit Report.

Section 1 Introduction

1-2


1.2 Background The EMUA owns and operates two wastewater treatment plants; the Elmwood and Woodstream wastewater treatment plants having a design average flow rating of 2.5 and 1.5 million gallons per day, respectively. Both treatment plants are located in Evesham, New Jersey. The collection system consists of 131 miles of sewer pipes and twenty three (23) remote pump stations. Seven of the pump stations serve the Woodstream collection system with the remaining pump stations serving the Elmwood collection system.

The Elmwood wastewater treatment plant utilizes the Activated Sludge Process to provide primary and secondary treatment for the removal of BOD5, ammonia, and suspended solids in the wastewater flow. Primary treatment consists of influent screening, grit removal, and influent pumping. Secondary treatment consists of aeration utilizing two Orbal aeration units, final sedimentation through two clariflocculators, rapid sand filtration, and chlorination and dechlorination using sodium hypochlorite and sodium bisulfate, respectively. Treated wastewater is ultimately discharged into the Southwest Branch of the Rancocas Creek.

Waste activated sludge removed from the clariflocculators is conveyed to the sludge thickening tank where it is aerated prior to being conveyed to the belt filter presses located in the Sludge Handling Facility where sludge cake is produced at a concentration of 18% minimum.

The Woodstream wastewater treatment plant also employs the Activated Sludge Process to provide primary and secondary treatment for the removal of BOD5 and suspended solids in the wastewater flow. Primary treatment consists of conveying the wastewater into a grit, grease and screenings removal unit where heavy inorganic solids, fats and grease are removed. Effluent from the grit, grease and screenings removal unit is conveyed to an equalization tank where the wastewater flow is mixed via aeration. Secondary treatment consists of utilizing two pre-packaged treatment units employing the contact stabilization process, a Biofor filtration system which provides both the physical removal of remaining solid matter and the biological removal of ammonia, and ultraviolet disinfection. Treated wastewater is ultimately discharged into the Pennsauken Creek.

Both pre-packaged treatment plants are equipped with aerobic digesters where the sludge is hauled to the Elmwood wastewater treatment plant for processing.

1.3 Purpose and Scope The objective of the energy audit is to identify energy conservation and retrofit measures to reduce energy usage and to develop an economic basis to financially validate the planning and implementation of identified energy conservation and retrofit measures.

Significant energy savings may be available with retrofits to the buildings’ envelopes, heating and cooling systems and lighting systems. It should be noted that the magnitude of energy savings available is not only dependent on the type of treatment process and delivery systems in use, but also on the age and condition of the equipment and the capital available to implement major changes. Therefore, with the growing demands for electricity and the increased cost for this electricity, feasible alternatives for reducing energy consumption and operating costs must be evaluated for each wastewater treatment plant on a case-by-case basis.

The purpose of this energy audit is to identify the various critical processes within the Elmwood and Woodstream wastewater treatment plant facilities that are major consumers of electrical energy and are clear candidates for energy savings measures. In addition, potential energy producing systems such as combined heat and power co-generation, solar electric, ground source heat pumps, and wind energy systems to be located at the wastewater treatment plants were also evaluated. A discussion on these technologies is included in Section 4 Energy Conservation and Retrofit Measures (ECRM).

The existing process systems that have been identified for possible energy savings retrofits include the following:

Internal Screw Lift Pumps;

Elmwood Wastewater Treatment Plant

Orbal Surface Aeration System;

Utility Plant Water System;

Waste Activated Sludge Holding Tank Mixing System;

Building HVAC Systems;

Building Lighting Systems; and

Motor Upgrades.

Equalization Tank Mixing System;

Woodstream Wastewater Treatment Plant

Contact Stabilization Package Plants Aeration System;

Ultraviolet Disinfection System;

Section 2 Facility Description

2.1 Elmwood Wastewater Treatment Facility The plant operates under NJPDES Permit No.NJ0024031 and is rated at an annual average flow of 2.5 MGD. The treated effluent from the wastewater treatment plant facility discharges by gravity to the Southwest Branch of the Rancocas Creek.

The Elmwood wastewater treatment plant utilizes the Activated Sludge Process to provide primary and secondary treatment for the removal of BOD5, ammonia, and suspended solids in the wastewater flow. Primary treatment consists of influent screening, grit removal, and influent pumping. Secondary treatment consists of aeration utilizing two Orbal aeration units, final sedimentation through two clariflocculators, rapid sand filtration, and chlorination and dechlorination using sodium hypochlorite and sodium bisulfate, respectively.

Waste activated sludge removed from the clariflocculators is conveyed to the sludge thickening tank where it is aerated prior to being conveyed to the belt filter presses located in the Sludge Handling Facility where sludge cake is produced at a concentration of 18% minimum.

2.1.1 Screening System Wastewater enters the screening facility via a thirty (30) inch diameter influent pipe where debris is removed by an automatic fine screen system. Screening material is collected in an enclosed bag to control odors prior to disposal.

2.1.2 Grit Removal System Wastewater flow from the screening system enters into a ten (10) foot diameter vortex grit tank where grit is removed from the wastewater in conjunction with gravity and forced vortex action. As the grit nears the center of the tank, a paddle increases the velocity of the grit particles forcing the grit into a hopper while maintaining the organics in suspension.

A vortex type grit pump is used to convey grit from the grit hopper to a grit concentrator and separator screen. The dewatered grit is then discharged to a dumpster for removal.

Wastewater flow exiting the grit removal system flows through a 1’-6” wide throat parshall flume where plant flow is measured and into the Influent Pump Station’s wet well via a thirty (30) inch effluent pipe.

2.1.3 Influent Pump Station The Influent Pump Station consists of three (3) forty-eight (48) inch diameter screw pumps inclined at a 45 degree angle with each pump having a 3,000 gallon per minute

flow capacity. Each pump is equipped with a 40 Hp constant speed motor. Typically, one internal screw pump is operation to convey average daily flow and a second pump is placed into operation, if required, to convey wet weather flows. Pump operation is controlled via a bubbler control system.

The wastewater flow from the grit removal system as well as wash water flow from the belt filter press system, drain lines from the Orbal aeration units, seal water flow from various pump systems, backwash flow from the sand filter system, and sanitary flow from various buildings within the treatment plant discharge into the pump station’s wet well. Wastewater flow from the screw pumps discharges into a distribution box which distributes the flow to the two Orbal aeration units.

2.1.4 Orbal Aeration System Wastewater flow from the screw pump distribution box is conveyed to a distribution box associated with each Orbal Aeration System whereby the flow can be distributed to Cell 1 and/or Cell 2 via the use of sluice gates. As the flow is discharged to Cell 1 or 2 of each Orbal Aeration System, it passes through one (1) or four (4) Palmer Bowlus flumes which measures and records the “relative” flow distribution to the various cells.

Each Orbal Aeration System is a multi-cell structure consisting of three (3) aeration cells and an outlet cell located at the center of each unit. Four (4) two speed forty (40) horsepower rotary aerator assemblies are provided for mixing and aeration within each aeration system. Molded thermoplastic discs are provided to provide the necessary mixing and oxygen transfer to the wastewater.

Three (3) variable speed screw-centrifugal type pumping units having 40 Hp motors are provided to return sludge from the clariflocculators to the Orbal Aeration System. The variable speed pumping system can vary the return activated sludge flow from 50% to 150% of the design average flow as required to balance the solids loading in the Orbal Aeration System.

Three (3) constant speed screw-centrifugal type pumping units having 3 Hp motors are provided to waste sludge from the activated sludge process.

2.1.5 Clariflocculators Wastewater flow from each Orbal Aeration System is conveyed by gravity to a sixty-five (65) foot diameter clariflocculator via a twenty-four (24) inch pipeline. The wastewater flow enters each clariflocculator through a thirty (30) foot diameter center influent well.

Scum and grease which enter the clariflocculator from the Orbal Aeration System are skimmed from the water surface by a full surface skimmer and discharged into a scum box where the grease and scum are combined with the settled sludge within the


2-3

clariflocculator. The quantity of settled sludge removed from the clariflocculator is controlled by a telescopic valve.

2.1.6 Rapid Sand Filtration Wastewater flow from the clariflocculators flows by gravity to the rapid sand filters’ distribution channel from a thirty (30) inch pipeline where fine suspended solids and phosphorous precipitates are further removed from the wastewater. Flow is distributed between filters by three (3) fixed weirs located in the distribution channel.

The rapid sand filtration system consists of three (3) sand filters 38’-0” in length and 12’-6” in width, with each sand filter having an effective filtering area of 432 square feet. At the design average flow of 2.5 million gallons per day, the filter loading rate is 2.0 gallons per minute/square foot with one filter out of service.

Filtered effluent flows into the effluent well, over an adjustable weir and into the effluent channel which conveys the wastewater flow by gravity to the chlorine contact tank for disinfection.

2.1.7 Disinfection Wastewater flow from the rapid sand filtration system enters the chlorine contact tank where the wastewater is disinfected using sodium hypochlorite and dechlorinated using sodium bisulfite. The chlorine contact tank consists of two tank sections with each section having dimensions of 90’ long by 13’-0” wide with an approximate water depth of 9 feet providing a contact time of thirty (30) minutes at average design flow with one tank section in service. Although the chlorine contact tank is provided with a two speed 7-1/2 Hp disk aerator for post aeration, the disk aerator is not placed into service as the dissolved oxygen concentration within the plant effluent is high enough to meet NJPDES permit limits for dissolved oxygen concentration.

Effluent from the chlorine contact tank is discharged by gravity through a thirty (30) inch pipeline and into the Southwest Branch of the Rancocas Creek.

2.1.8 Solids Handling 2.1.8.1 Sludge Thickening Tank Waste activated sludge from the clariflocculators is conveyed to the sludge thickening tank where the sludge is mixed via aeration prior to being conveyed to the belt filter press dewatering system.

The sludge thickener tank is 32’-6” in diameter with a side wall depth of 11’-0”. Originally, the sludge thickener tank was a clarifier from the “old” plant no. 2 prior to being converted into a sludge thickening tank. Waste activated sludge concentration within the tank ranges between 2% to 3% solids. Aeration is accomplished by employing two (2) 40 Hp rotary lobe positive displacement blowers with one blower normally in operation.


2-4

Thickened sludge is conveyed to the belt filter press dewatering system via the sludge transfer pumps.

2.1.8.2 Belt Filter Presses All sludge produced from the Elmwood and Woodstream Wastewater Treatment Plant facilities are dewatered at the Elmwood Wastewater Treatment Plant prior to ultimate disposal.

The Woodstream wastewater treatment plant also employs the Activated Sludge Process to provide primary and secondary treatment for the removal of BOD5 and suspended solids in the wastewater flow. Primary treatment consists of conveying the wastewater into a grit, grease and screenings removal unit where heavy inorganic solids, fats and grease are removed. Effluent from the grit, grease and screenings removal unit is conveyed to an equalization tank where the wastewater flow is mixed via aeration. Secondary treatment consists of utilizing two pre-packaged treatment units employing the contact stabilization process, a Biofor filtration system which provides both the physical removal of remaining solid matter and the biological removal of ammonia, and ultraviolet disinfection.

Both pre-packaged treatment plants are equipped with aerobic digesters where the sludge is hauled to the Elmwood wastewater treatment plant for processing.

2.2.1 Influent Pump Station Wastewater collected from the Woodstream Sewer Service Area enters a pump station (Pump Station Number 1), where the wastewater is collected and pumped into a Lakeside complete plant for the removal of screenings, grease, and grit material. The pump station consists of three (3) submersible variable speed 25 Hp pumps. Typically, two (2) pumps are in operation.

2.2.2 Screening, Grease, and Grit Removal System From Pump Station Number 1, wastewater is conveyed to a Lakeside complete plant which provides for the removal of screenings, grease, and grit. The screening removal portion of the complete plant incorporates a rotating screening basket having ¼ inch spacing with a peak flow capacity of 4.79 million gallons per day. The screening


2-5

system is also equipped with a wash water spray system which removes organic material and a screw press conveyer which removes excess water while reducing the screening material volume to at least 40% of its volume prior to discharge. Wastewater from the complete plant flows by gravity into the equalization tank.

2.2.3 Equalization Tank Wastewater flow from the Lakeside complete plant as well as filter backwash water from the Biofor system enters the equalization tank which is 48’-0”in diameter with a sidewall depth of 20’-0” and consisting of ninety-six (96) coarse bubble diffusers. Two (2) constant speed 60 Hp positive displacement blowers (normally one blower is in operation) provides the necessary aeration to keep the contents within the equalization tank well mixed before being conveyed to the two (2) pre-packaged contact stabilization plants by two (2) constant speed 7-1/2 Hp pumping units.

2.2.4 Pre-Packaged Contact Stabilization Plants Wastewater flow from the equalization tank is pumped into a flow distribution box which distributes the wastewater flow into two (2) pre-packaged contact stabilization plants numbered 1 and 2. Flow distribution is approximately 35% for plant number 1 and 65% for plant number 2.

Contact Stabilization Plant Number 1 has an outer diameter of 70’-0” with a clarifier diameter of 32’-6”. The plant is equipped with a reaeration zone having a 132,000 gallon capacity with a side water depth of 15’-0”, a contact zone having a 79,000 gallon capacity with a side water depth of 15’-0”, a clarifier having a 81,318 gallon capacity with a surface area of 829 square feet, and a digester zone having a 116,000 gallon capacity with a side water depth of 15’-0”.,

Contact Stabilization Plant Number 2 has an outer diameter of 84’-0” with a clarifier diameter of 41’-6”. The plant is equipped with a reaeration zone having a 208,000 gallon capacity with a side water depth of 15’-0”, a contact zone having a 95,000 gallon capacity with a side water depth of 15’-0”, a clarifier having a 124,609 gallon capacity with a surface area of 1,320 square feet, and a digester zone having a 171,000 gallon capacity with a side water depth of 15’-0”.,

Aeration is provided to the contact stabilization plants by three (3) constant speed centrifugal blowers. Two (2) blowers (numbers 1 and 2) are equipped with 150 Hp motors and the third blower (number 3) is equipped with a 100 Hp motor. Typically, blower number 1 or 2 provides air to contact stabilization plant number 2 and blower number 3 provides air to contact stabilization plant number 1.

Sludge produced from the two contact stabilization plants is hauled to the Evesham wastewater treatment plant for further processing.

Effluent from the contact stabilization plants is screened prior to being pumped to the Biofor filtration system via Pump Station Number 2.


2-6

2.2.5 Biofor Filtration System The Biofor system consists of three (3) up flow filter cells where ammonia is removed biologically and additional removal of suspended solid material occurs. Filtered effluent is collected in the filter system’s Clearwell Tank where the effluent flows by gravity to the ultraviolet disinfection system. Filter backwash water is collected in the filter system’s Mudwell Tank and conveyed back to the equalization tank.

2.2.6 Ultraviolet Disinfection System The Infilco DeDegremont, Inc. Aquaray 40 Ultraviolet (UV) Disinfection System consists of two channels having a total of 320 low pressure, low output lamps orientated in a vertical arrangement. Flow through the channel is perpendicular to the lamps. The two (2) channels consist of 2 banks (2 modules per bank), each rated to treat 2 MGD of wastewater flow at a design UV Transmittance of 65%. At the time of the energy audit, both channels were in use.

The banks are controlled and monitored by a PLC located in the Power Distribution System; however, the PLC control system is currently not in operation. As a result, all lamps are activated under full intensity during the course of the day independent of plant flow.

Effluent from the ultraviolet disinfection system discharges by gravity to the Pennsauken Creek.

2.3 Elmwood Administration Building with Attached Garage

2.3.1 Description of Building Envelope The energy audit included an evaluation of the building’s envelope (exterior shell) to determine the components’ effective R-values to be utilized in the building model and to locate and fix any thermal weaknesses that may be present. The components of a building envelope include the exterior walls, foundation and roof. The construction and material, age and general condition of these components, including exterior windows and doors, impact the building’s energy use.

The Elmwood Administration Building along with its Attached Garage’s walls consists of 4” brick and motar façade with 8” CMU back up blocks. The existing roofing system consists of metal roofing over a pitched roof deck with 3” rigid insulation above the 5/8” drywall attic ceiling. We were not able to access the roof at the time of the audit, but CDM did note small signs of interior leakage. This could indicate infiltration of water from the roof deck or condensation from piping.

The windows throughout the building are insulating double pane windows with weatherstripping. The majority of the doors are of steel and glass construction. It was observed that the double pane glass on the outside door have started to fail. The failure of the thermal insulating value of the double pane glass becomes apparent as


2-7

any moisture condenses between the two panes, which is identifiable by any clouding. Frosting or cloudiness occurring in double pane glass are signs that the seal between the two panes of glass containing the layer of air or gas is broken and allowing for moist air to enter, thus diminishing the thermal insulation value.

Our inspection has revealed that the building envelope is in good condition and is currently providing a high level of insulation. As such, any modifications to the insulation system would not prove to be cost effective, from an energy savings stand-point.

Section 3 Baseline Energy Use

3.1 Utility Data Analysis The first step in the energy audit process is the compilation and quantification of the facility’s current and historical energy usage and associated utility costs. It is important to establish the existing patterns of electric and gas usage in order to be able to identify areas in which energy consumption can be reduced.

For this study, the monthly gas and electric bills per facility were analyzed and unit costs of energy were obtained. The unit cost of energy, as determined from the information provided by the Authority, was utilized in determining the feasibility of switching from one energy source to another or reducing the demand on that particular source of energy to create annual cost savings for the Evesham Municipal Utilities Authority.

3.1.1 Electric Charges It is important to understand how the utility companies charge for the service. The majority of the energy consumed is electric, as a result of both indoor and outdoor lighting systems, pumping systems, and wastewater treatment processes and equipment. Electricity is charged by three basic components: electrical consumption (kWH), electrical demand (kW) and power factor (kVAR) (reactive power). The cost for electrical consumption is similar to the cost for fuel oil, the monthly consumption appears on the utility bill as kWH consumed per month with a cost figure associated with it. The service connections are either billed on a flat rate or time of day rates per kWH.

Electrical demand can be as much as 50 percent or more of the electric bill. The maximum demand (kW value) during the billing period is multiplied by the demand cost factor and the result is added to the electric bill. It is often possible to decrease the electric bill by 15 – 25 percent by reducing the demand, while still using the same amount of energy.

The power factor (reactive power) is the power required to energize electric and magnetic fields that result in the production of real power. Power factor is important because transmission and distribution systems must be designed and built to manage the need for real power as well as the reactive power component (the total power). If the power factor is low, then the total power required can be greater than 50 percent or more than the real power alone. The power factor charge is a penalty for having a low power factor.

The other parts of the electric bill are the supply charges, delivery charges, system benefits, transmission revenue adjustments, state and municipality tariff surcharges and sales taxes, which cannot be avoided.

3.4 Portfolio Manager 3.4.1 Portfolio Manager Overview Portfolio Manager is an interactive energy management tool that allows the Evesham MUA Authority to track and assess energy consumption at the WWTP in a secure online environment. Portfolio Manager can help the Evesham MUA Authority set investment priorities, verify efficiency improvements, and receive EPA recognition for superior energy performance.

3.4.2 Energy Performance Rating For many facilities, you can rate their energy performance on a scale of 1–100 relative to similar facilities nationwide. Your facility is not compared to the other facilities entered into Portfolio Manager to determine your ENERGY STAR rating. Instead, statistically representative models are used to compare your facility against similar facilities from a national survey conducted by the Department of Energy’s Energy


3-8

Information Administration. This national survey, known as the Commercial Building Energy Consumption Survey (CBECS), is conducted every four years, and gathers data on building characteristics and energy use from thousands of facilities across the United States. Your facility’s peer group of comparison is those facilities in the CBECS survey that have similar facility and operating characteristics. A rating of 50 indicates that the facility, from an energy consumption standpoint, performs better than 50% of all similar facilities nationwide, while a rating of 75 indicates that the facility performs better than 75% of all similar facilities nationwide.

The wastewater treatment plant facility is eligible to receive a rating, yet is not eligible for an Energy Star label.

3.4.3 Portfolio Manager Account Information A Portfolio Manager account has been established for the Evesham MUA Authority, which includes a profile for the Elmwood Wastewater Treatment Plant Facility and Woodstream Wastewater Treatment Plant Facility. Information entered into this Portfolio Manager Facility profile, including electrical energy consumption and natural gas consumption has been used to establish a performance baseline.

It is recommended that the information be updated to track the buildings’ energy usage. At the time of the audit the Elmwood Wastewater Treatment Plant received a rating of 41. The Woodstream Wastewater Treatment Plant received a rating of 2.

Section 4 Energy Conservation and Retrofit Measures (ECRM) The following is a summary of how Annual Return on Investment (AROI), Internal Rate of Return (IRR), and Net Present Value (NPV) will be broken down in the cost analysis for all ECRMs recommended in this report.

Included in the simplified payback analysis summary table is the ‘Annual Return on Investment’ (AROI) values. This value is a performance measure used to evaluate the efficiency of an investment and is calculated using the following equation:

Where OCS = Operating Cost Savings, and AECS = Annual Energy Cost Savings. Also included in the table are net present values for each option. The NPV calculates the present value of an investment’s future cash flows based on the time value of money, which is accounted for by a discount rate (DR) (assume bond rate of 3%). NPV is calculated using the following equation:

Where Cn=Annual cash flow, and N = number of years.

The Internal Rate of Return (IRR) expresses an annual rate that results in a break-even point for the investment. If the Authority is currently experiencing a lower return on their capital than the IRR, the project is financially advantageous. This measure also allows the Authority to compare ECRM’s against each other to determine the most appealing choices.

Where Cn=Annual cash flow, and N = number of years.

The lifetime energy savings represents the cumulative energy savings over the assumed life of the ECRM.

4.1 Elmwood Wastewater Treatment Facility CDM has evaluated the current operation of the Elmwood Wastewater Treatment Facility and has identified potential ECRMs to enhance the current process.

4.1.1 Orbal Aeration System The activated sludge process utilized at the Elmwood WWTP is the Orbal® three (3) channel complete mix, looped reactor system from Envirex which is now, Siemens Water Technologies. There are two (2) Orbal systems each with three (3) concentric channels, with the outer channel containing approximately 50% of the total volume. Wastewater flow from the screw pump distribution box enters a distribution box associated with the Orbal System whereby the flow can be discharged to the outer channel of each system which is operated under an oxygen deficit condition to promote simultaneous nitrification-denitrification. Although the actual oxygen demand of the first channel is approximately 75% of the total demand across the system, the aeration discs allotted to this channel only supply 30-60% of the systems overall oxygen requirements. This is done to ensure a constant DO deficit, an operating DO concentration of 0 mg/L, throughout this aerated anoxic reactor (channel). The simultaneous nitrification-denitrification results in an overall denitrification rate of 80%, without internal recycle.

The second aeration channel operates in a ‘swing’ mode, designed for 1 mg/L DO, which varies diurnally with the daily load conditions. The third channel is an anoxic zone that further removes nitrates.

The aerated channels of the Orbal systems contain unique (proprietary) aeration disks that provide high oxygen transfer and mixing efficiencies, with four (2) two-speed (1760 rpm, 1185 rpm) forty horsepower aerators supplying the air. At high speed an aerator motor draws 46.3 amps and at low speed, 34.3 amps.

The aeration system does not currently have an automated

Orbal System – Aerator Drives


4-3

DO control system. Discussions with plant staff indicated that dissolved oxygen levels and aerator speed adjustments are manual.

Table 4.1-1 summarizes baseline energy usage and annual energy cost for the Orbal Aeration System.

Table 4.1-1: Existing Annual Energy Consumption and Cost # of Aerators in Operation per System: 4 (24 hours, 7 days/week, 2 at half

# of Orbal Systems in Operation: 2

Amperage Draw per System: 161.2 amps

Total Amperage Draw for both Systems: 332.4 amps

Total Delivered Power1: 214.3 kW

Total Annual kWh: 1,878,413

Total Annual Energy Cost: $262,980

1. Power (W) = 3 (1/2) *Voltage*Current*Power Factor. An 80% power factor was assumed.

Oxygen requirements change continuously based on daily fluctuations in plant flow and loadings. Providing the correct monitoring and control systems for the aeration process is critical, since energy demand increases as the DO demand increases. The installation of a DO control system would automatically control aerator output and optimize energy usage.

Siemens provides a proprietary control system, SmartBNRTM, which addresses the precise control required to accomplish simultaneous nutrient removal in the aerated-anoxic reactor, through an integrated control strategy that utilizes both oxidation-reduction potential (ORP) and DO. The main function of the control system remains the optimization of delivered oxygen, by matching the oxygen delivery rate to the oxygen demand resulting in power cost savings.

The control system maintains precise reactor conditions to remove nitrogen and phosphorous as well as provide selection of microorganisms to minimize the chance of bulking or other interruptions in process efficiency.

The facility influent data was analyzed to determine a total estimated oxygen demand under average and monthly max conditions of 4,960 and 6,330 lbs O2/day, respectively. Based upon process operational data provided by the manufacturer, the published aeration disk oxygen transfer characteristic is 3.5 lbs O2/hour/bhp. Therefore, the current oxygen transfer rate supplied for both Orbal plants is 16,867 lbs O2/day calculated as follows:


4-4

However, accounting for age and wear on the equipment, and to account for a reduced oxygen transfer efficiency while the aerators are operating at low speed, a conservative transfer efficiency of 2.5 lbs O2/hr*bhp can be expected resulting in a daily oxygen delivery rate of 12,048 lbs O2/day, which is about twice the oxygen demand calculated under maximum month loading conditions.

The implementation of the SmartBNR control system and the installation of VFDs on the aerators would work to optimize the operation and turn down of the aerators to meet the required oxygen demand, resulting in the potential for a 50% annual energy savings of 939,207 kWh ($131,490). The following table, Table 4.1-2, summarizes the simple payback and financial analysis for the implementation of the SmartBNR control system.

4.1.2 Sludge Holding Tank – Mixing System The contents of the sludge holding tank at the Elmwood Facility is mixed using two (2) 40 Hp positive displacement blowers and a coarse aeration diffuser system. The blowers alternate, operating one at a time. The baseline energy consumption and annual energy cost for the existing mixing system is estimated to be 261, 400 kWh/yr (40Hp x 0.7468 kW/Hp x 8760 hrs/yr) and $36,600, respectively. One option for reducing the energy consumption within this system is to replace it with the installation of a jet mixing system.

The jet system is a submerged system which produces fine gas bubbles and enhances mixing between the gas and liquid phases. The fine bubble and intimate contacting results in increased absorption efficiency and less operating horsepower over conventional aeration mixing systems. Mixing System, Inc. is a typical manufacturer that can provide such a system. The system consists of an external pump which circulates sludge through a jet eddy mixer.

The proposed system for the sludge holding tank consists of one (1) ten jet eddy mixer and one external circulation pump.

The sludge holding tank was originally designed as a clarifier and therefore has a concentric design including an inner and outer tank. The inner tank of the sludge holding tank will need two 16-inch diameter openings for the jet mixer to pass through.

A design summary for the sludge holding tank is shown in Table 4.1-2.

Table 4.1-2: Jet Mixing System Design Summary Inner Tank Diameter 35.5 feet Outer Tank Diameter 71.5 feet Water Depth 20 feet (assumed) Tank Volume 600,000 gallons Solids Concentration 300 ppm

(assumed) Jet mixers/aerators per tank 1 Jets per mixer/aerator 10 Pump Flow 4,000 gpm Pump Bhp/hp 28/30 Mixing Intensity 46 BHP/MG Turnover Time 30 min

The average required power to mix the contents of the sludge holding tank would be approximately 28Hp (1 pump at 28Hp), which equates to an annual energy cost of approximately $25,600 and an annual energy consumption of 183,200 kWh/year.


4-6

Based upon the annual estimated baseline energy usage and cost of 261,400 kWh/yr and $36,600, respectively, the installation of a jet mixing system will result in an annual energy cost savings of $11,000 and energy consumption savings of 78,500kWh/year.

Refer to Appendix H for costs pertaining to the jet mixing system.

The above cost summary provides for the simple payback and financial analysis for retrofitting the sludge holding tank and reflects the normal operational mode of the sludge holding tank system.

Based upon the simple payback periods, internal rates of return and net present values presented in Table 4-6, it is not recommended that a jet mixer system be installed. However, it is recommended to replace the existing blower motors with high efficiency motors as discussed in Section 4.5.2.

4.2 Woodstream Wastewater Treatment Facility CDM has evaluated the current operation of the Woodstream Wastewater Treatment Facility and has identified potential ECRMs to enhance the current process.

4.2.1 Equalization Tank Mixing System The contents of the equalization tank at the Woodstream Facility is mixed using two (2) 60 Hp positive displacement blowers and a coarse air diffuser system. Typically, only one blower is in operation. The baseline energy consumption and annual energy cost for the existing mixing system is estimated to be 392,500 kWh/yr (60Hp x 0.7468 kW/Hp x 8760 hrs/yr) and $55,000, respectively. One option for reducing the energy


4-7

consumption within this system is to replace it with the installation of a jet mixing system as similarly described in Section 4.1.2.

The proposed system for the equalization tank consists of one (1) ten jet eddy mixer and one external circulation pump.

A design summary for the equalization tank is shown in Table 4.2-1.

Table 4.2-1: Jet Mixing System Design Summary Tank Diameter 48 feet Water Depth 20 feet Tank Volume 270,000 gallons Solids Concentration 1% Jet mixers/aerators per tank 1 Jets per mixer/aerator 10 Pump Flow 4,000 gpm Pump Bhp/hp 28/30 Mixing Intensity 103 BHP/MG Turnover Time 14 min

The average required power to operate one tank would be approximately 28Hp (1 pump at 28Hp), which equates to an annual energy cost of approximately $25,600 and an annual energy consumption of 183,200 kWh/year. Based upon the estimated baseline energy usage and cost presented of 392,500 kWh/yr and $55,000, respectively, the installation of a jet mixing system will result in an annual energy cost savings of $29, 400 and energy consumption savings of 209,300kWh/year.

Refer to Appendix H for costs pertaining to the jet mixing system.

Table 4.2-2: Jet Mixing System Probable Cost Summary New System Installation Cost $213,000


Annual O&M Cost $1,000

Simple Payback Period, years 7.5

Lifetime, years 20


Net Present Value (NPV) $224,000


4-8

The above cost summary provides for the simple payback and financial analysis for retrofitting the equalization tank and reflects the normal operational mode of the equalization tank system.

Based upon the simple payback periods, internal rates of return and net present values presented in Table 4.2-2, it is recommended that a jet mixer system, such as one manufactured by Mixing Systems Inc., be installed in order to achieve energy savings associated with the equalization tank aeration system.

However, should the Authority decide not to pursue this energy savings measure, then it is recommended to replace the existing blower motors with high efficiency motors as discussed in Section 4.5.2.

4.2.2 Extended Aeration System The activated sludge process utilized at the Woodstream WWTP is contact stabilization. There are two (2) contact stabilization packaged plants within circular concrete tanks that include four zones. The bulk of the finely suspended and dissolved organics are rapidly removed through adsorption within the first zone, the contact zone. This zone provides approximately 1/3 of the total detention time at average flow. The high uptake rate in this zone allows for the use of a short detention time overall. This is the main reason why contact stabilization, as with the case at Woodstream, has been historically applied as a means of secondary treatment within a minimum bioreactor volume.

Once the bulk of the organic material is removed within the contact zone, the mixed liquor flows to the settling zone were solid-liquid separation occurs. The settled sludge is then returned to the reaeration zone where the organic matter is oxidized and stabilized by microorganisms within the digester zone.

This activated sludge process utilizes an aeration system to provide oxygen for the biological oxidation of carbonaceous and nitrogenous matter and to ensure that the biological solids are maintained mixed within the wastewater. Aeration devices for wastewater treatment can be classified into two basic types:

(1) Agitating wastewater mechanically to dissolve oxygen from atmospheric air into the wastewater (mechanical aeration); or

(2) Introducing air or pure oxygen into the wastewater with submerged diffusers (diffused air).

The contact zone, reaeration zone and aerobic digester zones of the two (2) packaged contact stabilization plants are aerated with three (3) centrifugal blowers supplying


4-9

the air. The contact zone and reaeration zones are equipped with fine bubble diffusers and the digestion zone is equipped with coarse bubble diffusers. The following table, Table 4.2-3, provides a general description of the Contact Stabilization Plants.

Volume (ft3) 12,699 16,657 27,804 22,858

Aeration air is provided to the contact stabilization plants by three (3) constant speed centrifugal blowers. Two (2) blowers (numbers 1 and 2) are equipped with 150 Hp motors and the third blower (number 3) is equipped with a 100 Hp motor. Typically, blower number 1 or 2 provides air to contact stabilization plant number 2 and blower number 3 provides air to contact stabilization plant number 1. The blowers have been in operation for 30 years.

The aeration basins do not currently have a DO control system. Discussions with plant staff indicated that dissolved oxygen levels are typically maintained between 6 and 9 mg/L. In most wastewater treatment plants, a minimum dissolved oxygen (DO) level of 2.0 mg/l is commonly maintained in the aeration basins.

Currently, there is no recorded air flow data, so with the assistance of plant staff the power delivered to the aerated zones of the contact stabilization plants was determined from blower amperage readings taken on July 20, 2010 and are summarized in Table 4.2-4.

Table 4.2-4 summarizes the operating conditions utilized to estimate the annual cost of operation.

2. Power = 3 (1/2) *Voltage*Current*Power Factor. An 80% power factor was assumed.

CDM analyzed the existing conditions to determine if energy savings can be realized with blower modifications or replacements. In addition to potential equipment modifications or replacements, one of the more critical elements to any energy conservation project for aeration systems is a dissolved oxygen control system.

Oxygen requirements change continuously based on daily fluctuations in plant flow and loadings. Providing the correct monitoring and control systems for the aeration process is critical, since energy demand increases as the DO demand increases. The installation of a DO control system would automatically control blower output and optimize energy usage.

A typical automated DO control system is known as a DO loop. A DO loop control system consists of DO probes in each aeration bay to continuously monitor the DO levels, which are then fed back to the main control panel (MCP). The DO readings from the DO transmitters would be wired to a new PLC which could be connected to a SCADA system for monitoring and DO set point input. A software program in the PLC interprets the readings and sends a signal to the blower VFDs to maintain, increase, or decrease speed, depending on the DO reading when compared to a set DO point or range. The individual DO readings from each bay and measured air flow rates into each diffuser grid will be used to control the inlet air valves of each diffuser grid to maintain the desired DO concentration in each pass automatically. Each diffuser grid drop leg will be provided with one modulating control valve, one thermal dispersion flow meter and one isolation valve.


4-11

Since a course or fine bubble diffused air system distributes air at the bottom of the tank and the probe is at the water surface, the mixed liquor dissolved oxygen is fairly constant throughout the tank. Therefore, this type of control system works well for a course or fine bubble diffused aeration system providing instantaneous change in blower output under varying flows and loads to the plant. The control system would also allow for sequencing between the available blowers, depending upon the air demand.

Current Conditions The facility influent data was analyzed to determine the actual required blower demands for both Contact Stabilization Plants. This was based on a reported plant flow distribution of 35% to Plant 1 and 65% to Plant 2. Tables 4.2-5 and 4.2-6 present a summary of the relevant design parameters used to calculate the amount of air needed based on the actual current operating conditions.

This aeration analysis to determine the oxygen demand in lbs/day was completed on volumes of the contact zone, the reaeration zone and the digestion zone. The conversion to air flow (scfm) was based on the oxygen transfer efficiency (OTE) of fine bubble diffusers and coarse bubble in the digester zone.

1. Wastewater temperature was assumed, based on previous experience and operating data from plant’s in the vicinity.

The results of the aeration air analysis show that under current flow and load conditions including the air requirement for the aerobic digester section, the operation of one (1) 100 hp blower, at 70% speed, would satisfy the oxygen demand and maintain a dissolved oxygen concentration of 2.0 mg/L in both Contact Stabilization Plants during max day conditions.


4-13

A similar air analysis was conducted for the plant design flow of 1.5 MGD, assuming typical medium strength influent wastewater concentrations of 220 mg/l BOD and 220 mg/l TSS. The result of this analysis indicates that the total required design blower capacity is 85 hp for both plants. Therefore, under plant design conditions, one (1) 100 hp blower would satisfy the design oxygen demand.

Aeration System Improvement Alternatives To estimate potential energy savings for the aeration system, actual facility wastewater influent data were used to estimate the amount of air and power required for the aeration system for both Contact Stabilization Plants. The range as shown in Tables 4.2-5 and 4.2-6 is from 653 to 880 scfm and 47 hp to 70 hp.

To achieve energy savings for the aeration system, four (4) alternatives were evaluated: retrofitting the existing blowers with premium efficiency motors and VFDs, installing new centrifugal blowers with VFDs, installing new positive displacement blowers with VFDs and installing new turbo high-efficiency blowers with VFDs. Each alternative includes the installation of a DO control system to fully realize the potential energy savings by automatically controlling the blowers speed and associated output based upon measured DO concentrations.

A dissolved oxygen sensor and controller and flow control valves would be provided for each aerated zone. The dissolved oxygen feedback would be utilized to turn-down the blowers or to throttle the flow control valves, optimizing the delivery of the aeration air and the associated energy use.

Alternative 1: VFDs on Existing Centrifugal Blowers Review of the current operation of the aeration system has lead to the determination that there is adequate aeration air available through the operation of the existing blowers to maintain the process with a minimum DO set point of 2 mg/L throughout the aeration system volume.

The first alternative is to retrofit the existing blowers with variable frequency drives (VFDs) and new premium efficiency motors. Under average flow and load conditions, one 100 (hp) blower could operate at 50% speed assuming that this does not place the blowers in a surge operational condition. This results in an expected annual energy consumption (assuming 90.7% motors) of 360,251 kWh ($50,435) which is calculated as follows:

(100 hp/0.907*50%*0.746kW/hp*24 hr/day*365 days/year)= 360,251 kWh/year

Based upon this expected energy consumption, the potential annual energy cost savings is calculated to be $107,165.


4-14

Should the Authority elect not to install variable frequency drives for the existing blowers, then it is recommended that new premium efficiency motors, as a minimum, be installed in order to realize energy efficiency. Energy savings associated with new premium efficiency motors is detailed in Appendix L and Section 4.5.4.

Alternative 2: Installing New Centrifugal Blowers with VFDs Due to the age of the existing blowers, the installation of two (2) new 100 hp centrifugal blowers (one duty, one standby), with VFDs, has been evaluated. Based on the average annual air requirements and discussion presented under Alternative 1, this retrofit would also result in an estimated annual energy cost savings of $107,165.

Alternative 3: Installing New Positive Displacement Blowers with VFDs The third alternative is to replace the existing blowers with two (2) new positive displacement blowers (one duty, one standby). Manufacturers such as Aerzen or Dresser Roots can provide positive displacement blowers to meet the conditions of the facility. With a preliminary selection from Roots of a 75 hp blower (brakehorsepower of 60 Hp), the estimated annual energy consumption and cost is 392,097 kWh/yr and $54,894, respectively, resulting in an annual energy cost savings of $102,706.

Alternative 4: Installing New Turbo Blowers with VFDs

A final alternative is the installation of new turbo blowers (one duty, one standby). Based on the average annual air requirements, this retrofit would result in a preliminary 100 hp blower (brakehorsepower of 84 Hp)having an estimated annual energy consumption and cost of 548,940 kWh/yr and $76,850, respectively resulting in an annual energy cost savings of $80,750.

The following table, Table 4.2-7, summarizes the simple payback and financial analysis for these four alternatives.

Based upon the simple payback periods, internal rates of return and net present values of the energy savings alternatives evaluated, it is recommended that the existing blowers be retrofitted with VFDs and a DO control system be implemented to achieve the greatest energy savings.

However, based upon the age of the existing blowers, they have exceeded their useful life and replacement should be considered by the Authority. Should the Authority consider replacing the existing blowers, then Alternatives 2 through 4 should be considered as viable replacement options. This report, however, based solely upon the simple payback analysis, will recommend the installation of variable frequency drives and new premium efficient motors for the existing blowers.

4.2.3 Ultraviolet Disinfection System The UV disinfection system consists of two (2) channels; each channel includes two (2) banks of UV lamp modules. The banks span the width of the channel. A bank of lamps consists of 2 modules, each module consisting of 40 low pressure, low output (LPLO) lamps suspended from racks.


4-16

The UV disinfection system is operated year round. The system is currently not operating in automatic and consequently all banks are operated continuously to ensure compliance with the plant’s discharge permit. The UV system is sized such that a flow between 0 and 2 MGD will require that two banks be energized. One bank is adequate to treat 1 MGD each; however, operating with only one bank in service is not recommended as the bank does not span the entire channel. The electrical energy demand for each UV module is 3 kW (2 module/bank, 6 kW per bank).

Analysis of the plant’s current operating procedure is presented in Appendix F. The current operation with 4 banks on continuously equates to an annual energy usage of 228,384 kWh/year and at $0.14/kWh an annual operating cost of $31,974. This does not account for maintenance time required for cleaning of the lamp modules and / or replacement of lamps or ballasts. The current cleaning system requires removal of a UV bank from the channel, to be soaked in a chemical cleaning tank.

Two potential energy savings measures have been considered: the upgrade to the UV system controls to allow for flow pacing of the banks and due to the age of the existing system, the replacement of the existing LPLO system with a low pressure, high output (LPHO) system.

Configuration of Automatic Flow Pacing

As discussed previously, the UV Disinfection system no longer operates automatically based on flow conditions. Upgrading to incorporate automatic flow pacing, controlling the operation of the UV banks, would at a minimum involve the installation of a new plc based control panel with operator touch screen that would be interfaced with the influent flow or water level over the influent and effluent weirs to calculate the required UV dose and associate that to the operation of the UV banks.

As presented in Appendix F, it is projected that with the ability to energize only the necessary banks that an annual energy savings of 171,288 kWh may be possible, an annual energy cost savings of $23,980.

New Low Pressure, High Output (LPHO) System

An attractive feature of low pressure, high output lamps is the ability to ramp the power up and down to each bank in the disinfection channel. Additionally the higher output of the lamps will allow for greater treatment capacity through the same volume (existing channels). For Woodstream, the implementation of a LPHO system would result in the ability for one module of lamps (1/2 a bank) to treat 2 – 2.5 MGD of flow.


4-17

This increase in treatment capacity is not currently necessary, but upgrading the existing system to an LPHO system result in greater operational flexibility and energy efficiency of the UV Disinfection system.

An annual energy cost savings of $23,980 has been conservatively estimated, although there may be potential for further energy savings as a result of the ability to ramp the power up and down to each bank in an LPHO system.

The following table, Table 4.2-8, summarizes the simple payback and financial analysis for these two alternatives.

4.3 Building Lighting Systems The goal of this section is to present any lighting energy conservation measures that may also be cost beneficial. It should be noted that replacing current bulbs with more energy-efficient equivalents will have a small effect on the building heating and cooling loads. The building cooling load will see a small decrease from an upgrade to more efficient bulbs and the heating load will see a small increase, as the more energy efficient bulbs give off less heat.

Two options are offered for all buildings. The first option will be for upgrading existing interior lighting, if applicable. The second option will be for upgrading existing exterior lighting that is fed from the building. A total cost for upgrading both options at the same time will be presented. The overall site lighting for each plant, such as street and area lighting, has been broken out separately for simplified analysis. For the building interior options, retrofitting of existing fluorescent fixtures includes upgrading both ballasts and lamps for the fixture. Refer to Appendix D for more information.

For all of the buildings, it was noted there were no existing interior occupancy sensors installed. Installing occupancy sensors in rooms where there are none will typically increase energy savings; however, if the space is not occupied often in the first place, there will be little savings by installing occupancy sensors. Therefore, occupancy sensor installation has been recommended in this report. Refer to Appendix D for occupancy sensor locations and quantities.

Please note that the Engineer’s Estimate of Probable Construction Costs presented herein are estimates based on historic data compiled from similar installations and engineering opinions. Additional engineering will be required for each measure identified in this report and final scope of work and budget cost estimates will need to be confirmed prior to the coordination of project financing or the issuance of a Request for Proposal.

4.3.1 Elmwood Administration Building with Attached Garage It is recommended that the existing lighting system at Elmwood Administration Building with Attached Garage be upgraded to high efficiency standards to create lighting uniformity throughout the building.

4.4 Building HVAC Systems The goal of this section is to present any heating and cooling energy reduction and cost saving measures that may also be cost beneficial. Where possible, measures will be presented with a life-cycle cost analysis. This analysis displays a payback period based on weighing the capital cost of the measure against predicted annual fiscal savings.

Some buildings, with more complex HVAC systems, were modeled to more accurately predict energy usage savings from certain recommendations. Buildings modeled were done so using software called eQUEST, a Department of Energy-sponsored energy modeling program, to establish a baseline space heating and cooling energy usage. Climate data from Glassboro, NJ was used for analyses. From this, the model may be calibrated, using historical utility bills, to predict the impact of theoretical energy savings measures. However, because each site has one electric bill, CDM was not able to accurately track electric heating requirements for each individual building at the wastewater plants. The electric usage for heating is extremely small when compared to the electric use that is process related. For this reason, modeling all of the buildings and calibrating to the entire plant’s electric bill would not be beneficial for estimated electrical heating or energy savings.

There is one gas meter at each of the two plants. At the Elmwood site, three buildings are on one gas meter. These buildings are the Administration Building with attached Garage, the Sludge Recirculation/Alum Storage Building, and the Sludge Dewatering Building. All three buildings were modeled and their predicted gas usages were combined and calibrated to the actual usage. The Control/BioFor Building is the only building that uses gas at the Woodstream site.

Once annual energy savings from a particular measure have been predicted and the initial capital cost has been estimated, payback periods may be approximated. Equipment cost estimate calculations are provided in Appendix G. Building eQUEST model run summaries for ECRMs may be found in Appendix C.

4.4.1 Elmwood Wastewater Treatment Plant As stated above, the entire Elmwood Wastewater Treatment Facility is on one electric bill. Modeling all of the buildings and calibrating to the entire plant’s electric bill would not be beneficial for estimated electrical usage or energy savings. However, there are three buildings that have gas heating. The three buildings that have gas heating are all billed on one account. The Administration Building with Attached Garage, the Sludge Recirculation/Alum Storage Building, and the Sludge Dewatering Building were modeled and calibrated to match the actual gas usage for the plant. To calibrate the models, CDM used natural gas bills from July 2009 through May 2010. Figure 4.4.1-1 below compares actual monthly gas usages, with those predicted by the


4-34

eQUEST models for the three buildings. The models combined are modeled within 1% of the actual usage.

Figure 4.4.1-1: Elmwood Wastewater Treatment Plant – Natural Gas Usage

4.4.2 Elmwood Administration Building with Attached Garage The Elmwood Administration Building with Attached Garage office area is heated by natural gas furnace units. The office area is cooled by a split direct-expansion air conditioning system. Rooms are individually controlled by programmable thermostats. The setpoint of these thermostats ranges from 69-74 degrees F. From midnight to 5 AM the building is unoccupied and the thermostats are setback. The garage is heated by gas fired radiant tube heaters and electric unit heaters. For a more detailed equipment description refer to Section 2.3.2. Figure 4.4.2-1 below shows the natural gas usage for the Administration Building with Attached Garage. The predicted usage is calibrated based on the summation of the three buildings to the single gas account. Therefore the predicted usage shown below is based on a model that is a fraction of the total calibrated usage.

CDM recommends replacing the furnaces with high-efficiency, condensing furnaces.

CDM anticipates that four (4) 100 MBH input high-efficiency condensing furnaces should adequately heat the building.

Figure 4.4.2-2 compares current gas usage with predicted gas usage resulting from a switch to high-efficiency, condensing furnaces. Condensing furnaces are modeled with a full-load efficiency of 93%.

There are four 6 ton Trane air-cooled condensing units located outside of the building. The condensing units are tied to direct-expansion coils located in the four air handling units in the mechanical room. This provides cooling throughout most of the Administration Building. Two of them have either exceeded or are approaching their AHRAE expected lives. One of them is 17 years old, and the other is 20 years old. It should be noted, that over time, efficiency declines and equipment degrades. Due to age of service and improvements in equipment efficiency, these units should be replaced. The two older condensers are modeled with an efficiency of 8 EER. The largest cooling capacity that can be realized with a current residential condensing furnace is 5 tons. The following analysis was completed with the replacement condensing units sized at 5 tons and an efficiency of 12.3 EER. Figure 4.4.2-3 below shows the existing, and replacement cooling electrical usage next to each other for comparison.

Predicted fiscal savings from such an upgrade are identified in Table 4.4.2-2 below. A 5 ton condensing unit must have an SEER rating of at least 14 to receive an incentive from New Jersey Clean Energy SmartStart program. The costs associated with each of the new units can be seen in Appendix H. Due to the entire plant being on a single electric bill, the Elmwood Administration Building with Attached Garage electrical usage is not calibrated to actual usage. The savings and payback displayed below are based off a model of the Elmwood Administration Building with Attached Garage, and further investigation is warranted before proceeding.

Over several decades, ASHRAE has compiled data pertaining to service lives of most HVAC related equipment. From this, ASHRAE indicates a median service life (life until replacement) for HVAC related equipment that may be used as an estimate for the useful life of HVAC equipment currently in service. For example, ASHRAE indicates a window air conditioning unit has a median service life of 10 years. Therefore, if a window unit has been in service for more than 10 years, the owner may want to consider replacement. Not only will a replacement ensure minimal downtime between units (the unit is replaced before it ceases to function), but it will also maintain rated system efficiency, as efficiency tends to decrease with age.

All major equipment associated with the Elmwood Administration Building with Attached Garage noted during CDM’s on site audit is listed in Table 4.4.2-3, along

with ASHRAE-expected service lives. It should be noted that equipment that was not seen while on site and was observed on the provided drawings are included. Where equipment ages were not found on the equipment tags, they have been estimated based on the unit appearance, approximate renovation dates, or last manufacture date of the particular model. Additionally, in cases where a unit’s manufacturer and/or model could not be determined due to an unreadable, faded, destroyed, or lost tag, manufacturer and model number information has been represented as “unknown”.

4.4.5 Elmwood Sludge Dewatering Building The Elmwood Sludge Dewatering Building is heated by a Weil McLain cast-iron gas fired hot water boiler. The hot water is pumped to hot water unit heaters located in the building. An electric base Authority heater provides heat to the Lavatory. Motorized dampers and exhaust fans provide ventilation to the building. The office is heated and cooled by a wall mounted heat pump unit. For a more detailed equipment description refer to Section 2.6.2. Figure 4.4.5-1 below shows the natural gas usage for the Elmwood Sludge Dewatering Building. The predicted usage is calibrated based on the summation of the three buildings to the single gas account. Therefore the predicted usage shown below is based on a model that is a fraction of the total calibrated usage.


4-44

Figure 4.4.5-1: Elmwood Sludge Dewatering Building – Natural Gas Usage

Currently, the heating system utilizes one (1) gas-fired Weil McLain cast iron boiler, with an input rating of 455 MBH. A hot water gross I=B=R rating of 359 MBH gives this boiler an overall efficiency of 79%.

CDM recommends replacing this boiler with a high-efficiency, condensing boiler.

CDM anticipates that one (1) 399 MBH input high-efficiency condensing boiler should adequately heat the building.

Figure 4.4.5-2 compares current gas usage with predicted gas usage resulting from a switch to a high-efficiency, condensing boiler. Condensing boilers are modeled with a full-load efficiency of 92% and return water temperature as low as 100°F in mild weather.

Fiscal savings from such an upgrade are then identified in Table 4.4.5-1 below. Lifetime savings calculations for all ECRM’s may be found in Appendix I. It’s important to note that these are estimates based on building models, and further investigation is warranted before pursuing boiler replacements.

Due to the improved automation and control within modern condensing boilers, their operation and maintenance costs tend to be less than those of typical cast iron boilers. CDM estimates a cast iron boiler system of this size will typically cost around $1,750 per year for regular preventative maintenance, whereas a condensing boiler system would cost around $1,000 per year. Therefore, replacing the existing boiler with a condensing boiler should result in an operation and maintenance cost savings of $750 per year.

4.4.7 Woodstream Control/BioFor Building As stated above, the entire Woodstream Wastewater Treatment Facility is on one electric bill. CDM is only evaluating the Control/BioFor Building and Blower Building. The electrical usage was not calibrated due to the majority of electrical usage comes from process loads, and CDM is not evaluating all the buildings at the Woodstream site. However, the Control/BioFor Building is the only building that uses gas. The Control/BioFor Building was modeled and calibrated to match the actual gas usage. To calibrate the model, CDM used natural gas bills from January


4-48

2008 through June 2010. Figure 4.4.7-1 below compares actual monthly gas usages, with those predicted by the eQuest model. The models combined are modeled within 1% of the actual usage.

Figure 4.4.7-1: Woodstream Control/BioFor Building –Natural Gas Usage

The Woodstream Control/BioFor Building is heated by unit heaters, a gas fired hot water boiler and an air handler unit with an internal hot water heating and cooling coil. A condensing unit provides cold refrigerant to the air handling unit’s coils. The gas boiler serves hot water unit heaters in the Electrical, Generator, and Maintenance Rooms of the Administration Building. The air handling unit delivers cooling and heating to the remainder of the Administration Building. Roof mounted exhaust fans exhaust air from the Maintenance Room. A Zonex System controller monitors and determines the heating and cooling conditions in the Administration Building. There are five gas fired unit heaters in the Biofor Room. Exhaust fans and motorized inlet dampers provide ventilation for the room. For a more detailed equipment description refer to Section 2.9.2.

There is a 12.5 ton Rheem air-cooled condensing unit located outside of the building. The Authority has documented that the unit has ceased working. The current unit has an EER of 9.2. The replacement unit must have at least an efficiency of 11.5 EER to receive the New Jersey SmartStart incentive. The following analysis was completed with the replacement condensers sized at 12.5 tons and an efficiency of 11.5 EER. CDM made calls to representatives to get a budget price on such a unit, but due to the size, they were unable to give an accurate figure. Representatives said that a site visit

Predicted fiscal savings from such an upgrade are identified in Table 4.4.7-1 below. The costs associated with the new unit can be seen in Appendix H. A 12.5 ton condensing unit must have an EER rating of at least 11.5 to receive an incentive from New Jersey Clean Energy SmartStart program. Due to the entire plant being on a single electric bill, the Woodstream Control/BioFor Building electrical usage is not calibrated to actual usage.

4.5 Motor Upgrades and VFD Additions The goal of this section is to present any energy conservation measures related to upgrading motors to premium efficiency models, and adding variable frequency drives (VFD) that may also be cost beneficial.

To model the expected energy savings from upgrading motors to premium efficiency models, and the addition of VFDs, MotorMaster+ 4.0 software was utilized. Additional installation and labor costs were modeled using CostWorks software.

Additional benefits when adding VFDs include removal of traditional motor starters, lower stress levels on the motor bearings and windings, and a decrease in stress and wear on the motor/pump.

Application of a VFD to a pump results in a cubic power reduction with speed, where a 1% reduction in pump speed, will result in a 4% reduction in energy usage required to drive the pump. For the pumps which we added VFDs at the Elmwood and Woodstream treatment plants, we assumed a 25% decrease in energy usage, which results in a 6.25% reduction in pump horsepower.

Please note that the Engineer’s Estimate of Probable Construction Costs presented herein are estimates based on historic data compiled from similar installations and engineering opinions. Additional engineering will be required for each measure identified in this report and final scope of work and budget cost estimates will need to be confirmed prior to the coordination of project financing.

In addition, several of the motors surveyed had unreadable nameplate data. Therefore, CDM has assumed standard NEMA efficiencies for these motors for analysis. Refer to Appendix L for individual motor and VFD information.

4.6 Alternative Energy Sources 4.6.1 Photovoltaic Solar Energy System Overview Photovoltaic (PV) cells convert energy in sunlight directly into electrical energy through the use of silicon semi conductors, diodes and collection grids. Several PV cells are then linked together in a single frame of module to become a solar panel. PV cells are able to convert the energy from the sun into electricity. The angle of inclination of the PV cells, the amount of sunlight available, the orientation of the panels, the amount of physical space available and the efficiency of the individual panels are all factors that affect the amount of electricity that is generated.

Based on the estimated cumulative total available land area, calculations determine that the installation of a photovoltaic (PV) solar energy ground system will be appropriate for the Elmwood Treatment Plant, and Woodstream Treatment Plant.

As part of this energy audit, a preliminary engineering feasibility study of the wastewater treatment plants was completed, and consisted of the following tasks:

a. Site Visit by our engineers;

b. Satellite Image Analysis and Conceptual design and layout of the photovoltaic system;

c. Design and construction cost estimates;

d. Determine a preliminary design for the size and energy production of the solar system.

The total unobstructed available area of land with southern exposure was evaluated. It is important to note the following:

1. The PV system sizing and kWh production was calculated assuming the installation of a crystalline module facing south direction (220 Degree Azimuth) and tilted approximately 20 degrees to allow better rain water shedding and snow melting. Please note that the kWh production as well as system size may differ significantly based on final panel tilt selected during the design phase.

2. Blended electric rates were used based on actual utility bills and were applied for the facility.

The following is a preliminary study on the feasibility of installing a PV solar system at the Elmwood and Woodstream treatment plants to generate a portion of the facilities electricity requirements. The system is designed to offset the electric purchased from the local utility and not as a backup or emergency source of power.

In order to determine the best location for the installation of the PV solar system, a satellite image analysis and site walk through of the facilities was performed on July 13-14th, 2010. Also, as part of our assessment, we investigated possible locations for electrical equipment that need to be installed such as combiner boxes, disconnect switches and DC to AC inverters. Consideration was also given to locations of interconnection between the solar system and the facilities electrical grid.


4-66

4.6.1.1 Elmwood Wastewater Treatment Plant There is no amount of shading on the land that may have an impact to the design and layout of a solar PV array. The quality of land was not confirmed, and prior to installation of a solar array, site analysis should determine if the land is feasible for a PV solar system.

The Project Team conducted both a facility walk through and a satellite image analysis and based on the estimated available area calculations predict that a system rated at approximately 238.3 kW (dc) is feasible.

Electrical Service The electrical service size of the Elmwood Wastewater Treatment Plant is 1600 A, at 277/480V, 3-phase. The interconnection point for the PV system will require a modification or replacement of the existing service entrance equipment wherein the PV system feeder connections will have to be made after the main circuit breaker, and protective relaying will also have to be implemented. Preferably, the AC inverter should be installed in close proximity to the service entrance equipment, but in the case of the Elmwood Wastewater Treatment Plant, the main circuit breaker is the standby generator building and there is little to no available space. The inverter should be installed outside on a concrete pad in a weather proof enclosure. AC wiring would run from the inverters into the connection point(s) at the service entrance equipment. Any connection points would have to meet NEC and local utility requirements. Further investigation and verification of the clearances required for the standby generator, and the existing electrical equipment would be required prior to implementation of a PV system.

4.6.1.2 Woodstream Wastewater Treatment Plant There is a minimal amount of shading on the land that may have an impact to the design and layout of a solar PV array. A shading analysis would need to be performed during the design phase of the project. The quality of land was not confirmed, and prior to installation of a solar array, site analysis should determine if the land is feasible for a PV solar system.

The Project Team conducted both a facility walk through and a satellite image analysis and based on the estimated available area calculations predict that a system rated at approximately 67.8 kW (dc) is feasible.

Electrical Service The electrical service size of the Woodstream Wastewater Treatment Plant is 2000 A, at 480V, 3-phase. The interconnection point for the PV system will require a modification or replacement of the existing service entrance equipment wherein the PV system feeder connections will have to be made after the main circuit breaker, and


4-67

protective relaying will also have to be implemented. Any connection points would have to meet NEC and local utility requirements. Further investigation and verification of existing electrical equipment would be required prior to implementation of a PV system.

4.6.1.3 Basis for Design and Calculations The most common solar PV system is referred to as a (“fixed tilt”) system typically mounted to a metal rack that can be fixed at a specific angle. There are also (“tracking systems”) or movable along one or two axes to follow the position of the sun during the day. For a roof-mounted PV system, tracking systems are very rarely installed and are usually used for ground-mounted systems only, as they require more complex racks and higher maintenance costs. For the “fixed” system, the tilt is determined based on the following factors: geographical location, total targeted kWh production, seasonal electricity requirements and weather conditions such as wind. Ideally, the module tilt for Southern New Jersey should be 25-35 degrees with an azimuth as close as possible to 180 (south); however, our experience has shown that PV systems are typically installed at a tilt of 20 degrees or lower in order to avoid any issues with wind and to maximize total system size.

The type of PV panels and equipment used to mount the system shall be determined based on the wind conditions determined during the design phase of the project. In general, penetration/tie-down systems, non-penetrating ballasted type systems, or a combination of the two should be considered.

Calculation of PV System Yield An industry accepted software package, PV Watts, was used to calculate projected annual electrical production of the crystalline silicon PV system in its first year, as summarized in Table 4.5-1. The system was design to provide maximum kWh production based on available land space. The assumptions we used in the calculations were as follows: average monthly electrical usage per month of each facility, average aggregate electrical rate of each facility, square feet of available land space, and a solar rating of 3.89 kWh/m^2 per day.

Total Costs It should be noted that construction costs are only estimates based on historic data compiled from similar installations, and engineering opinion. Additional engineering and analysis is required to confirm the condition of the land, the system type, sizing, costs and savings. For illustration purposes, a draft financial analysis pro forma is attached outlining all project costs and revenues, Refer to Appendix E.

Table 4.6-2 Solar PV Array Engineer’s Opinion of Probable Cost

Engineer’s Opinion of Probable Cost $3,693,625

As stated above the engineer’s opinion of probable costs are based on experience with the pricing of solar installations in New Jersey, and are intended to provide the Authority with a reasonable budget cost. A typical solar installation can vary in cost from $7.00 - $10.00 per watt depending on size, complexity of the system, labor rates, etc. Approximately 60-70% of that number is material costs while the balance is labor, engineering, etc. Like any installation, certain conditions can affect a price upward or downward. We have included a budget of $9/watt for the solar system installation with an additional estimated budget of $100,000 for potential electric service work.

Based on a simple payback model, summarized in Table 4.6-1, it would benefit the Evesham MUA to further investigate the installation of a solar energy system at the Elmwood Treatment Plant, but not at the Woodstream Treatment Plant. This is


4-69

primarily based on the initial upfront capital investment required for a solar energy system installation and the 13.3 year payback period for the Elmwood Treatment Plant, and a negative net present value (NPV) for the Woodstream Treatment Plant. This payback period may justify installing the solar energy system. Other options such as Power Purchase Agreements are potentially available as well to help finance the project. Solar technology is constantly changing and will most likely continue to lower in price. Two major factors influencing the project financial evaluation is the variance of the prevailing energy market conditions and Solar Renewable Energy Credit (SREC) rates, with the largest impact to the payback model being the SREC credit pricing.

Table 4.6-1 includes the total simple payback analysis for the installation of a solar energy system at the Evesham and Woodstream MUA facilities. Refer to Appendix E for a more detailed solar financing spreadsheet.

Refer to Section 7 for discussion on Solar Renewable Energy Certificates and other financing options for solar projects. The financial model in Appendix E provides an annual forecast illustration of project revenues and costs for 25 years.

4.6.2 Ground Source Heat Pump Systems Ground source heat pumps utilize the relatively constant temperature of underground water sources to reject or supply heat to the interior space. Water is pumped through a loop that runs from the underground source to heat pumps at the building level. Depending on the time of year and building demand, these heat pumps use the ground source loop as a heat source or a heat sink.

Typically, ground source heat pump systems are most efficient when used in spaces that have similar heating and cooling loads, as the same loop and heat pumps are used for both cooling and heating. For wastewater treatment plant facilities, the heating and cooling loads are essentially unequal with most of the cooling in plant process areas achieved by ventilation of outdoor air to meet code requirements. Furthermore, as a water conservation measure, the cooling medium for a proposed ground source geothermal system will likely consist of treated plant effluent, which, although treated, will tend to foul heat transfer components as a result of inherent microbiological organisms present in the cooling media. Potential fouling of heat transfer components will result in increased maintenance efforts and system outage.

Ground source heat pump systems are often very costly to install due to the high cost of test boring and drilling wells. Due to this, the largely unbalanced heating and cooling demands at wastewater treatment plants, and the potential fouling of heat transfer components, CDM anticipates that installation of a ground source heat pump system would not prove cost-beneficial.


4-70

4.6.3 Wind Power Generation On-site wind power generation typically utilizes a form of turbine, which is rotated with the flow of wind across it, this rotational force powers a generator, producing DC electricity. The DC electricity is then converted into AC electricity, which can be used for commercial power, or can be fed back into the power grid, reducing the overall electric demand. The size of the turbine is proportional to the amount of wind and concurrently the amount of energy it can produce.

CDM has determined that it is not feasible for the Evesham MUA to install wind turbine energy systems at its facilities. This is primarily due to 50 year payback for averaged wind speeds. There are many other incentives that could possibly provide additional funding which would reduce the payback period further.

Because the Authority does not have a large area for installation of a larger wind turbine at any of the two locations surveyed for the audit, a small 5kW wind turbine was chosen. A turbine of this size could be installed in most locations. Depending on area available, and funding, the A may choose to install more than one wind turbine on the premises.

Utilizing NASA’s Atmospheric Science Data Center online wind mapping tool, it was determined that the local average wind speeds for the Evesham MUA ranged from 3.6 m/s to 5.2 m/s at 30 meters above the ground. In general, around 7mph of average wind speed, as determined over the course of a year, is necessary to “fuel” the turbine. These values fall within the range of feasibility for installation of a new wind turbine system.

For the purposes of this feasibility analysis, CDM chose a 5kW Endurance S-343 wind turbine. Please refer to Appendix M for vendor information. This turbine size is used most often for small commercial applications. Power Curve data was determined through the use of the product specification sheets on vendor websites. Actual turbine size, height, location, and manufacturer should be determined upon design of a wind turbine system.

The estimated wind speed data, associated wind probability distribution function (weibull value), turbulence losses, and other relevant data were then incorporated into Wind Cad to estimate the annual output for the wind turbine. Refer to Appendix J for Wind Cad Modeling.


4-71

This simple payback calculation takes into account the incentive provided for wind turbines through the REIP program. For the first 16,000 kWh of production, the incentive is $3.20/kWh. For production between 16,000 kWh – 750,000 kWh the REIP program incentive is $0.50/kWh. CDM used this incentive as an upfront deduction from the Engineer's Opinion of Probable Cost. In addition, in order to benefit from the REIP incentive, the Authority must purchase a wind turbine on the approved NJ Clean Energy list. CDM chose the Endurance S-343 wind turbine for this analysis as it is approved by the NJ Clean Energy program and is the appropriate size for smaller commercial installations and the limited area available on the site. Refer to the NJ Clean Energy website for more information.

Table 4.6-3 includes a simple payback analysis for the installation of one wind turbine energy system. Refer to Appendix K for a more detailed wind turbine financing spreadsheet, including utility cost avoidance and REC’s.

the Authority to further investigate the installation of a wind energy system at its facilities. This is primarily based on the initial upfront capital investment required for a wind turbine energy system installation and the 50 year average wind speed payback period.

It should be noted that CDM used only REC values, utility cost avoidance factors, and the REIP incentive in determining simple payback periods. As stated above, other incentives and financial programs such as Power Purchase Agreements are available to help finance this installation. For example, if a Power Purchase Agreement is completed, the private company financing the project would benefit from the 30% tax credit. Other incentives such as CREB's and first year usage incentives could be available to the Authority in lowering the payback period. Refer to www.dsireusa.org for an extensive listing of possible incentives for the New Jersey area.

The NJBPU has compiled a list of “Trade Allies” that include certain renewable energy system installers, vendors, and manufacturers. This list is not an endorsement or a requirement for qualifying for benefits under the REIP. To be listed in the Trade Ally database, the installers must have completed three successful installations with three completed and approved projects within NJCEP per category. Therefore, the Authority may choose a different company than is listed in the Trade Ally database to install a renewable energy system should the project be implemented.

It should also be noted that the wind turbine represented above is for feasibility purposes only. If the Authority decides to install a wind turbine, different mounting heights, turbine sizes, and manufacturers should be considered. In addition, permits may be required for installation according to local zoning laws. The FAA must also be notified in order to give clearance for the tower, and for installation of aviation safety lights if necessary.

4.6.4 Combined Heat and Power Cogeneration Technology The feasibility study to implement combined heat and power cogeneration systems at the Authority’s wastewater treatment plants was not conducted as the plants do not employ the anaerobic digestion process and therefore digester gas is not available as potential fuel. Furthermore, the natural gas service main serving the wastewater treatment plants cannot convey the required gas flow to support a reasonable sized cogeneration system in terms of electrical energy production without making extensive changes to the gas main and service requirements.

Section 5 Evaluation of Energy Purchasing and Procurement Strategies 5.1 Energy Deregulation In 1999, New Jersey State Legislature passed the Electric Discount & Energy Competition Act (EDECA) to restructure the electric power industry in New Jersey. This law, the deregulation of the market, allowed all consumers to shop for their electric supplier. The intent was to create a competitive market for electrical energy supply. As a result, utilities were allowed to charge Cost of Service and customers were given the ability to choose a third party supplier. Energy deregulation in New Jersey increased the energy buyers’ options by separating the function of electricity distribution from that of electricity supply.

Public Service Enterprise Group (PSE&G) is currently the supplier of electrical energy for the Evesham Elmwood and Woodstream Wastewater Treatment Plant Facilities.. Energy deregulation creates the opportunity to choose your electric generation supplier. The benefit of this is the ability to choose a supplier based on what is important to you, for example, lowest rate or how the electric generation supply is produced.

To sell electric generation service in New Jersey, electric power suppliers must be licensed by the New Jersey Board of Public Utilities (NJ BPU). They must also be registered with the local public utility (PSE&G) to sell electric service in that utility’s service areas. The following suppliers are licensed with the NJ BPU and are registered to sell electric service in the PSE&G service territory:

Amerada Hess Corp BOC Energy Services Con Edison Solutions, Inc. Constellation New Energy, Inc. Direct Energy, LLC. First Energy Solutions Corp. Glacial Energy Integrys Energy Service Liberty Power Pepco Energy Services, Inc. PP&L Energy Plus, LLC. Reliant Energy Solutions East, LLC. Sempra Energy Solutions South Jersey Energy Strategic Energy LLC Suez Energy Resources NA, Inc UGI Energy Services

5.1.1 Alternate Third Party Electrical Energy Supplier In evaluating the potential for an alternative third party supplier, CDM contacted and requested a proposal for electrical service from First Energy Solutions Corp. The objective of which was to get an overall idea of whether or not switching electric energy suppliers is an avenue that should be pursued further to obtain electrical energy cost savings.

First Energy Solutions Corp has proposed a flat rate retail cost per kWh over the next 6 or 12 month period. The proposal is included in Appendix N.

The following tables, Table 5.1-1 and Table 5.1-2, summarize the annual cost savings available based on historical energy consumption and the proposed energy rate for a 12 month term. The retail rates used in this analysis represent the baseline generation rates from the two suppliers and do not include any applicable demand charges, societal benefits charges, transmission charges, energy charges, reconciliation charges, transitional assessment charges or system control charges that were included in the aggregate rates presented in Section 3. These baseline generation rates, are used for comparison purposes to identify any potential energy cost savings, as all other applicable charges cannot be avoided by switching suppliers. This summary table, which utilizes the historical electrical energy usage provided, confirms the information and available cost savings presented by First Energy Solutions Corp.

As energy cost savings are available by switching to a third party supplier, such as First Energy Solutions Corp, this is a recommended energy cost savings measure. The estimated annual cost savings available by switching to First Energy Solutions Corp is a 56% savings. CDM recommends that Evesham MUA investigate this opportunity further and compare proposals from alternate third party suppliers to obtain the lowest electrical energy rates available.

5.2 Demand Response Program Demand Response is a program through which a business can make money on reducing their electricity use when wholesale electricity prices are high or when heavy demand causes instability on the electric grid, which can result in voltage fluctuations or grid failure. Demand Response is an energy management program that compensates the participant for reducing their energy consumption at critical times. Demand Response is a highly efficient and cost effective means of reducing the potential for electrical grid failure and price volatility and is one of the best solutions to the Mid-Atlantic region’s current energy challenges.

The program provides at least 2 hours advance notice before curtailment is required. There is typically 1 event a year that lasts about 3 hours in the summer months, when demand for electricity is at its highest. Participation in Demand Response is generally done through companies known as Curtailment Service Providers, or CSPs, who are members of PJM Interconnection. There is no cost to enroll in the program and participation is voluntary, for instance, you can choose when you want to participate. In most cases, there is no penalty for declining to reduce your electricity use when you’re asked to do so. The event is managed remotely by notifying your staff of the curtailment request and then enacting curtailment through your Building Management System. CSPs will share in a percentage of your savings, which may differ among various CSPs, since there may be costs associated with the hardware and/or software required for participation, so it is recommended that a number of CSPs be contacted to review their offers.

Section 6 Ranking of Energy Conservation and Retrofit Measures (ECRM) 6.1 ECRMs The main objective of this energy audit is to identify potential Energy Conservation and Retrofit Measures and to determine whether or not the identified ECRM’s are economically feasible to warrant the cost for planning and implementation of each measure. Economic feasibility of each identified measure was evaluated through a simple payback analysis. The simple payback analysis consists of establishing the Engineer’s Opinion of Probable Construction Cost estimates; O&M cost savings estimates, projected annual energy savings estimates and the potential value of New Jersey Clean Energy Rebates or Renewable Energy Credits, if applicable. The simple payback period is then determined as the amount of time (years) until the energy savings associated with each measure amounts to the capital investment cost.

As discussed in Section 3, aggregate unit costs for electrical energy delivery and usage and natural gas delivery and usage, which accounts for all demand and tariff charges at each complex, was determined and utilized in the simple payback analyses.

In general, ECRMs having a payback period of 20 years or less have been recommended and only those recommended ECRMs within Section 4 of the report have been ranked for possible implementation. The most attractive rankings are those with the lowest simple payback period.

Ranking of ECRMs has been broken down into the following categories:

6.1.5 Solar Energy Implementation of a new solar energy system has been evaluated to determine the economic feasibility for furnishing and installing such systems for the Evesham MUA. Based on the simple payback modeling performed, it would benefit the Authority to further investigate installing the solar energy system at the Elmwood Treatment Plant, and not the Woodstream Treatment Plant. This is primarily based on the initial upfront capital investment required for a solar energy system installation and the 13.3 year payback period for the Elmwood Treatment Plant, and a negative net present value (NPV) for the Woodstream Treatment Plant.

Two major factors influencing the project financial evaluation is the variance of the prevailing energy market conditions and Solar Renewable Energy Credit (SREC) rates, with the largest impact to the payback model being the SREC credit pricing. For the payback model, conservative estimates of the SREC’s market value over a 15 year period were assumed, as discussed in Section 4.6.

Table 6.1-4 includes a simple payback analysis for the installation of solar energy systems at the Elmwood and Woodstream Treatment Plants. Refer to Appendix E for a more detailed solar financing spreadsheet.

Section 7 Grants, Incentives and Funding Sources 7.1 Renewable Energy 7.1.1 Renewable Energy Certificates (NJ BPU) As part of New Jersey’s Renewable Portfolio Standards (RPS), electric suppliers are required to have an annually-increasing percentage of their retail sales generated by renewable energy. Electric suppliers fulfill this obligation by purchasing renewable energy certificates (RECs) from the owners of solar generating systems. One REC is created for every 1,000 kWh (1 MWh) of renewable electricity generated. Although solar systems generate electricity and SRECs in tandem, the two are independent commodities and sold separately. The RPS, and creation of RECs, is intended to provide additional revenue flow and financial support for renewable energy projects in New Jersey. Class I RECs, which include electricity generation from wind, wave, tidal, geothermal and sustainable biomass typically trade at around $25/MWh. RECs generated from solar electricity, or SRECs, trade at $550/MWh due to supplemental funding from NJ PBU. The supplemental funding will decrease over time to $350/MWh.

7.1.2 Clean Energy Solutions Capital Investment Loan/Grant (NJ EDA) NJ EDA in cooperation with NJ DEP is offering interest-free loans and grants for energy efficiency, combined heat and power (CHP) and renewable energy projects with total project capital equipment costs of at least $1 million. The interest-free loans are available for up to $5 million, a portion of which may be issued as a grant. The most recent round was closed as of October 2009, but new CESCI program updates will be posted at www.njeda.com. For additional information, [email protected] or call 866-534-7789.

7.1.3 Renewable Energy Incentive Program (NJ BPU) The Renewable Energy Incentive Program (REIP) provides rebates for installing solar, wind, and sustainable biomass systems in Smart Growth regions. Rebates of $1.00 per watt are available for solar electricity projects up to 50 kW in capacity. Wind systems can receive rebates up to $3.20 per expected kWh produced. Sustainable biomass rebates start at $4.00 per watt installed with a maximum incentive amount of 30 percent of project costs. REIP will give out $53.25 million in rebates from 2009 - 2012. Project owners must complete the Pay for Performance Program, Direct Install or Local Municipal audit, or the rebate will be reduced by $0.10 per watt.

The REIP Funding Cycle 2, opened May 3, 2010, for solar installation incentives was recently closed. The budget is currently being reviewed and there is still expectation for Funding Cycle 3 to open in September.

Section 7 Available Grants, Incentives and Funding Sources

7-2

7.1.4 Grid Connected Renewables Program (NJ BPU) The New Jersey Grid Connected Renewables Program offers competitive incentives for wind and sustainable biomass electricity generation projects larger than 1 Megawatt (MW). Applications for the most recent round of funding, which totaled $6 million, were due January 8, 2010. Requests for Proposals (RFPs) for the next round will be posted at www.njcleanenergy.com and www.state.nj.us/bpu. A total of roughly $16 million is available for incentives under this program during 2010. Most of the incentives offered under this program will take the form of a payment for energy production ($/MWh) once the project is operating. Incentives range up to $58.49/MWh for publicly-owned wastewater biogas projects. Up to 10% of the incentive may be requested in the form of a lump grant to cover up-front costs such as financing fees, interconnection fees, project design, permitting, and construction costs.

7.1.5 Utility Financing Programs All four Electric Distribution Companies (EDCs) in New Jersey have developed long term contracting or financing programs for the development of solar energy systems. In all of the programs, Solar Renewable Energy Credits (SRECs) generated by the solar energy systems will be sold at auction to energy suppliers who are required to purchase a certain quantity of SRECs to meet their Renewable Portfolio Standard requirements.

7.1.6 Renewable Energy Manufacturing Incentive (NJ BPU) New Jersey’s Renewable Energy Manufacturing Incentive (REMI) program provides rebates to purchase and install solar panels, inverters, and racking systems manufactured in New Jersey. Rebates for panels start at $0.25 per watt and rebates for racking systems and inverters start at $0.15 per watt for solar projects up to 500 kW in capacity. To be eligible for REMI, applicants must apply to either the Renewable Energy Incentive Program (REIP) or the SREC Registration Program (SRP).

7.1.7 PSE&G Solar Loan Program Public Service Electric and Gas (PSE&G) of New Jersey will offer $143 million in loans to their customers for solar electric systems in 2009-2010. Their Solar Loan program will provide 15-year loans at an interest rate of 11.3092% to cover 40-60% of the cost of solar systems 500 kW in capacity or less. PSE&G customers may repay the loan through cash payments or by signing over their Solar Renewable Energy Certificates (SRECs) to PSE&G. Loan applications are scheduled to be accepted on a quarterly basis. For more information, call 973-430-8460.

7.1.8 Environmental Infrastructure Financing Program (NJ DEP) The Environmental Infrastructure Financing Program (EIFP) provides low-interest loans for the planning, design and construction of a variety of water, wastewater and stormwater infrastructure projects. NJ DEP traditionally provides loans at 0% interest for approximately 20 years for up to one-half the allowable project costs. The remaining project costs are funded through 20-year loans at about the market rate or

less. Approximately $100 million-$200 million is available per year. In 2009, 20 percent of the projects funded were required to be “green infrastructure” projects, including energy efficiency and renewable energy projects. Applicants must submit a commitment letter in the beginning of October and an application in March annually. For more information, contact Stanley V. Cach, Jr. Assistant Director NJDEP-Municipal Finance and Construction Element at 609-292-8961 or [email protected].

7.1.9 Clean Renewable Energy Bonds (IRS) CREBs are 0% interest bonds typically issued for up to approximately $3.0 million administered by the Internal Revenue Service (IRS). Last year, $2.2 billion in CREBs was allocated to municipal entities to fund 610 renewable energy projects, including anaerobic digestion. IRS has been allocating funding for CREBs annually since 2005. Last year, IRS solicited applications starting in April, which were due in August. The IRS is expected to receive additional funding for CREBs and release another round of solicitations in 2010.

7.1.10 Qualified Energy Conservation Bonds (IRS) These IRS 0% interest bonds are very similar to CREBs except they are allocated based on state and county population. New Jersey was allocated $90 million as part of the ARRA stimulus fund. QECBs are typically distributed through municipal bond banks or state economic development agencies.

7.1.11 Global Climate Change Mitigation Incentive Fund (US EDA) The Economic Development Agency (part of the U.S. Department of Commerce) administers the GCCMIF to public works projects that reduce greenhouse gas emissions and creates new jobs. In FY 2009, $15 million was allocated to the fund, and additional funding is expected to be allocated in FY 2010. Applications are due on a rolling basis. The program does not have a maximum grant amount but does limit the grant to 50 percent of the project cost.

7.1.12 Private Tax-Exempt Financing Similar to traditional municipal bond financing, there are many private financial service companies that offer a myriad of options for tax-exempt financing of municipal projects. The providers of these services suggest that this capital can be offered at competitive rates in an expedited timeframe and with fewer complications when compared to traditional municipal financing methods. Though these factors would need to be compared on a case-by-case basis, the one distinct advantage to private financing on the current project would likely be the flexibility to structure payments to meet budget needs with consideration given to the terms and conditions of existing loan and/or bond agreements. For example, this mechanism could be used to limit the digestion project dept payments in the initial years when the current bond debt is the greatest and the operations savings of the project has yet to be fully realized. It should also be noted that, in many cases, the construction and long term



7-4

financing can be rolled into a single private financing agreement. Also, in some instances, equipment manufacturers have the ability to offer competitive financing terms (e.g. Siemens Financial Services Corporation), though financing from these sources is generally contingent upon a substantial portion of the project cost (~20% to 30%) being for their respective equipment.

7.1.13 Performance Based Contracts (ESCOs) A second financing alternative for a project of this nature would be to enter into a Performance Based Contract with an Energy Services Company (ESCO). The premise of this type of contract is that it requires no initial municipal capital contributions in order to implement the project - instead relying on future operations cost savings and/or energy production, to fund the annual payments. Prior to entering into an agreement for the funding of the project, an ECSO would perform an energy audit and/or conceptual studies to confirm future energy cost savings or energy production inherent with the projects implementation and operation. The contract would then be formulated based on some measurable parameter(s) (sludge reduction, energy production, etc) which would be verified by measurement throughout the contract duration. The savings in energy costs or energy production would then be used to pay back the capital investment of the project over the contract time period (typically on the order of 10-years or less). The ESCO would guarantee the agreed upon energy savings or energy production. If the project does not meet energy savings or production commitments, the ESCO pays the owner the equivalent difference.

With this funding alternative, the ownership and operation of the facility would be maintained by the original owner. A performance contract may also include ESCO operation and maintenance of the energy-related facilities if that were deemed appropriate. Significant ESCO’s with experience in this area include Siemens Building Technologies, Chevron and Johnson Controls. CDM has functioned in several roles on performance based contracts including being the owner’s representative and, on different contracts, providing design-build services (as a subcontractor to the ECSO). We can provide additional experience-based information upon request.

7.1.14 Power Purchase Agreements (SPCs) More commonly referred to as a Build-Own-Transfer (BOT) agreement in the Water/Wastewater industry, a Power Purchase Agreement (PPA) also delivers a project with no initial capital contribution by the original owner. In this model, a Special Purpose Company (SPC) created by a developer, would own the energy production facilities. Within the framework of a PPA, a SPC will typically lease property from the owners for construction and operation of the new facilities. The funding and construction of the new facilities would be performed by the SPC who would then own and operate the facilities for the duration of the contract (typically 20 to 30 years). Throughout that period of time, the original owner would purchase power from the SPC at a pre-negotiated rate which would take into account the initial capital cost, operation and maintenance of the constructed facility, ancillary benefits of the project and investor returns on investment. For renewable energy, financial


7-5

incentives may enable this financing approach to compete favorably with utility power tariffs. Incentives include state and local tax credits, renewable energy credits, and Federal energy production tax credits or energy investment tax credits. It is expected that a number of experienced companies and developers may be interested in a PPA for New Jersey municipal renewable energy projects.

7.2 Energy Efficiency 7.2.1 Introduction New Jersey's Clean Energy Program (NJ CEP) promotes increased energy efficiency and the use of clean, renewable sources of energy including solar, wind, geothermal, and sustainable biomass. The results for New Jersey are a stronger economy, less pollution, lower costs, and reduced demand for electricity. NJCEP offers financial incentives, programs, and services for residential, commercial, and municipal customers.

NJCEP reduces the need to generate electricity and burn natural gas which eliminates the pollution that would have been caused by such electric generation or natural gas usage. The benefits of these programs continue for the life of the measures installed, which on average is about 15 years. Thus, the public receives substantial environmental and public health benefits from programs that also lower energy bills and benefit the economy.

7.2.2 New Jersey Smart Start Buildings Program (NJ BPU) The New Jersey Smart Start Buildings Program offers rebate incentives for several qualifying equipment such as high efficient premium motors and lighting, and lighting controls.

Incentive information and incentive calculation worksheets are provided for the various new equipment installation identified in this report and are included in Appendix F.

7.2.3 Pay for Performance Program (NJ BPU) Another program offered through the New Jersey Smart Start Program, is the Pay for Performance Program. Commercial, industrial and institutional buildings with an average annual peak demand over 200 kW are eligible for participation. In addition, local government agencies, which do not meet the 200 kW demand requirement and are not receiving Energy Efficiency and Conservation Block Grants are eligible.

Incentives are available for buildings that are able to present an Energy Reduction Plans that reduce the building’s current energy consumption by 15% or more, in addition to incentives for installing the recommended measures and incentives for presenting the energy savings in a post-construction benchmarking report. No more than 50% of the total energy savings may be derived from lighting retrofits. In addition, the total energy savings of 15% may not come from the implementation of one energy savings measure.

7.2.4 Local Government Energy Audits (NJ BPU) New Jersey’s Clean Energy Program offers an incentives program that will subsidize the cost of an energy audit for local government entities. This audit identifies cost-justified energy efficiency measures for sites in the service territory of one of New Jersey’s regulated electric and/or gas utilities.

The program provides guidance to eligible entities as they select buildings to be audited. Participants in the program then select one of the pre-qualified energy auditing firms that will produce a report to satisfy program requirements. The program will then subsidize 75% of the cost of the audit. The remaining 25% of the cost will be subsidized if the participant expends that sum of money implementing energy efficiency upgrades. All recommended measures are eligible for additional incentives available through the NJ SmartStart Buildings Program. However, these incentives will be subtracted from the cost of the installed measures.

Applications for this program are submitted for each individual building and will be considered on a building-by-building basis. Funds are awarded on a first-come, first-serve basis and case-by-case basis.

7.2.5 Free Energy Benchmarking Industrial facilities are eligible for a free energy benchmarking assessment conducted by the NJ Board of Public Utilities. This benchmarking provides energy managers with a building energy performance assessment and valuable information on how to get an energy efficiency project started. The benchmarking process may involve comparing a facility’s energy use to that of its peers (dependent upon availability of sufficient comparative data), or simply its own energy use year-to-year. If the building type fits either the EPA’s ENERGY STAR® Portfolio Manager or EPA Energy Performance Indicator models, then its energy performance is compared to national data for similar buildings. The five major benchmarks used to analyze building performance include: electricity use, heating fuel use, weather-normalized heating fuel use, total cost, and total cost per resident, all of which are normalized for comparison by square footage and weather. If an ENERGY STAR benchmark is conducted, a detailed description of the building’s specific score is included in the report.

The analysis included in each report is based on the information provided on a Building Data Request Form submitted by the owner/manager, which includes building, energy supplier, and other information. The building’s utility bills are also used to assess its electricity and heating fuel consumption for the year(s) provided. The benchmarking report includes: a summary table of each building’s energy use and cost information, assessment of the building’s carbon footprint, recommended next steps, and information on other offerings available through New Jersey’s Clean Energy Program. Please contact Joe Carlamere of New Jersey’s Clean Energy Program at 732-855-2895 for additional information.

7.2.6 Clean Energy Solutions Capital Investment Loan/Grant (NJ EDA) NJ EDA in cooperation with NJ DEP is offering interest-free loans and grants for energy efficiency, combined heat and power (CHP) and renewable energy projects with total project capital equipment costs of at least $1 million. The interest-free loans are available for up to $5 million, a portion of which may be issued as a grant. The most recent round was closed as of October 2009, but new CESCI program updates will be posted at www.njeda.com. For additional information, [email protected] or call 866-534-7789.

7.2.7 Direct Install (NJ BPU) Owners of existing small to mid-size commercial and industrial facilities with a peak electric demand that did not exceed 200 kW in any of the preceding 12 months are eligible to participate in Direct Install. Buildings must be located in New Jersey and served by one of the state’s public, regulated electric or natural gas utility companies.

This program will cover up to 80% of the retro-fitting costs associated with the use of new energy efficient equipment. Lighting, HVAC, refrigeration, motors, natural gas systems, and variable frequency drives are covered under the Direct Install program.

7.2.8 Environmental Infrastructure Financing Program (NJ DEP) The Environmental Infrastructure Financing Program (EIFP) provides low-interest loans for the planning, design and construction of a variety of water, wastewater and stormwater infrastructure projects. NJ DEP traditionally provides loans at 0% interest for approximately 20 years for up to one-half the allowable project costs. The remaining project costs are funded through 20-year loans at about the market rate or less. Approximately $100 million-$200 million is available per year.

incentive Amount – Program Incentives will equal either: a) the approved Program Incentive amount, or b) the actual equipment cost of the Energy-Efficient Measure, whichever is less, as determined by the Market Manager. Products offered at no direct cost to the customer are ineligible. Incomplete application submissions, applications requiring inspections and unanticipated high volume of activities may cause processing delays. Program Incentives are limited to $500,000 per utility account in a calendar year. Contact the Market Manager regarding any questions.

tax liability – The Market Manager will not be responsible for any tax liability that may be imposed on any Participating Customer as a result of the payment of Program Incentives.

Incentive Amount: ......................................$0.10 per sq ftMinimum Incentive: ...................................$5,000

Maximum Incentive:: .................................$50,000 or 50% of facility annual energy cost

This incentive will be developed to offset the cost of services associated with the development of the Energy Reduction Plan. Projects must identify efficiency improvements that meet the minimum performance level in order to become eligible for Incentive #1. Incentive amount will be based on the square footage ofthe building.

Electric IncentivesBase Incentive based on 15% savings: ......$0.11 per projected kWh savedFor each % over 15% add: .........................$0.005 per projected kWh savedMaximum Incentive: ..................................$0.13 per projected kWh saved

Gas IncentivesBase Incentive base on 15% savings: ........$1.10 per projected Therm savedFor each % over 15% add: .........................$0.05 per projected Therm savedMaximum Incentive: ..................................$1.45 per projected Therm saved

This incentive will be based on projected energy savings and designed to pay approximately 60% of the total performance-based incentive. Savings projections will be calculated using calibrated energy simulation and rounded to the nearest percent. Incentive #2 may not exceed 30% of the total project cost.

Level 1:Fuel cells not fueled by Class I renewable fuel ...................................................$4.00........................................................................................................... 60%

This incentive will be released upon submittal of a Post-Construction Benchmarking Report that verifies that the level of savings actually achieved by the installed measures meets or exceeds the minimum performance threshold. To validate the savings and achievement of the Energy Target, the EPA Portfolio Manager shall be used. Savings should be rounded to the nearest percent. Total value of Incentive #2 and Incentive #3 may not exceed 50% of the total project cost. This incen-tive will "true up" proposed savings and the related payment for Incentive #2 so that the total incentive is based on actual savings. For buildings not covered by EPA, the process used by LEED EB shall be followed.

Incentive Structure for NJ Pay For Performance Program

Designed for small to medium-sized facilities, Direct Install, by New Jersey’s Clean Energy Program, cuts energy costs by replacing eligible lighting, HVAC, motors, natural gas, refrigeration and other equipment with higher effi ciency alternatives. The program pays up to 80% of retrofi t costs, dramatically lowering your upfront costs and improving your payback on the project. Services are provided by a network of Participating Contractors who perform

Energy Assessments to identify eligible alternatives and then install the qualifying measures.

NJCleanEnergy.com/ssb

The program is completely turnkey!Participating Contractors are approved to perform Energy Assessmentsand install the energy efficient equipment in your building.

Costs to you are minimal!Your share of the project’s cost will be approximately 20%, New Jersey’s Clean Energy Program pays the remaining 80%. With incentives sodramatic, your payback can be less than 2 years.

Turnaround time is quick!Direct Install is designed to fast-track project implementation so yourbusiness can begin saving on energy costs sooner rather than later. Participating Contractors will perform the Energy Assessments and implement the recommended effi ciency measures quickly.

Owners of existing small buildings to mid-size commercial andindustrial facilities with a peak electric demand that did not exceed200 kW in any of the preceding 12 months are eligible to participate in Direct Install. Buildings must be located in New Jersey and served by one of the state’s public, regulated electric or natural gas utility companies.

This is a Conceptual Level Opinion of Probable Cost only. CDM has no control over the cost of labor, materials, equipment, or services furnished, over schedules, over contractor's methods of determining prices, competitive bidding (at least 3 each - both prime bidders and major subcontractors), market conditions or negotiating terms. CDM does not guarantee that this opinion will not vary from actual cost, or contractor's bids. There are not any costs provided for: Change Orders, Client Costs, Finance or Funding Costs, Legal Fees, Land Acquisition or temporary/permanent Easements, Operations, or any other costs associated with this project that are not specifically part of the bidding contractor's proposed scope.

Since some of the work will occur in older buildings, there is the potential to encounter asbestos or other materials requiring special removal and handling. Currently available information is not adequate to determine if such conditions exist, consequently these costs are not included in this estimate.

This estimate does not consider escalation of costs over time

From: roger dixon [mailto:[email protected]] Sent: Tuesday, August 17, 2010 10:18 AM To: Flynn, Andrew J. Cc: 'Brent Krohn' Subject: RE: Ballpark Installed Costs Since this is a school and I presume a non‐profit, the 30% ARRA tax credit on RE systems would not apply. However, there might be other funding available. You can hit this website, www.dsire.com for additional information. You can also Google up the “Wind for Schools” program that the US DOE has. This is a very good program. The equipment cost for the Endurance S‐343 turbine with a 90’ monopole would be $44,995 as a package, plus freight to NJ, approximately $2000. Wind data monitoring instrumentation, etc. will run another $2500. In NJ you will need to use prevailing wage labor rates for excavation, footings, electrical, assembly and erection, etc. on a municipal/school project. I would figure another $20‐$25k or so. The total will be approximately $70‐$75,000 all in. I would appreciate you keeping me in mind if the project moves ahead. With this in mind I have also attached a short bio for your perusal.
