The Case For Micro-Grids

Heavily burdened, aging electrical grid

The toll of power disruptions

How a Microgrid Works

Honeywell.comà



White Oak MicrogridDefinition White Oak FDA Microgrid

Local Power Generation • 26MW power supply (currently being expanded to 55MW to handle the installation’s peak load)

• Leverage waste heat (Trigen) to condition buildings

• Puts more power on the grid than it takes off

Co-exist With The Utility • Works in parallel with Pepco under a three-party Interconnect Agreement.

• Participate in demand response events

• Utilize spinning reserve to maintain energy surety

Can Operate Totally Independent of Utility Grid (Islanding Capability)

• Operate mission critical functions independent of Pepco, enabling FDA to continue operations regardless of what happens outside the campus

Ability to Manage and Control Your Local Load

• Match load to supply

• Ability to make power purchase decisions

FDA White Oak Challenge

Mission: • Campus integrates FDA’s functions to increase scientific

synergy and collaboration. • Protect consumers from unsafe products, address threats

before they arise, and help deliver safer foods and safer, more effective medical therapies.

Requires an islanded microgrid to meet GSA/FDA

requirements

Needs:• Energy Security • Energy Surety• Energy Efficiency & Renewable Energy Mandates• Ability to Expand as Campus Expands

Challenges:• Budget Constraints (New Construction ESPC)• Ability to Balance Sometimes Conflicting Needs• Aging Utility Infrastructure

Optimization – Key to Success

Additional Value:• Expanded Auto Load Shed Scheme• Additional Dual-fuel Generation Assets• Combined Heat and Power – Maximizing BTUs• Interconnect Agreements With the Utility

Honeywell, GSA and FDA Work Together to Operate the Facility in the Best Interest of the Government.

Initial Strategy

Near continuous operation of engine-generator

Current Operations

Real-time “make or buy” decision based upon cost of natural gas, electric tariff, campus loads vs. engine & cogeneration efficiencies

Innovative ECMs

Instituted capability to participate in Pepco Gold Days putting power back on the grid when requested.Eliminated peak load charges as well.

Automated Demand Response

(Auto DR)

Quantified above standard efficiency in new buildings, purchased equipment and provided funding.

Combined Heat & Power (Trigen)

Waste heat utilized to heat/cool buildings. More BTUs for every KW.

BiofuelsAdding capability to use biofuels for fuel flexibility for energy

security and increasing options if natural gas prices increase.

Lowered Total Energy Consumption Through Both Innovative and Traditional ECMs Throughout The Entire

Campus.

Chilled Water Thermal Energy

Storage

Water supply was single point of failure – needed to keep cooling towers operational. Chilled Water Storage connected to towers

mitigating risk.

Reliability Metrics

Uptime Uptime over the last 12 months is > 99.999%.

RedundancyRedundancy provided for all critical systems.

Island Mode

Islanded, either automatically or manually, more than 70 times over the past 2 ½ years. Operations have not been interrupted for any weather related events.

Power Generation

On a yearly basis more power is supplied to Pepco than Pepco supplies to the White Oak Campus.
