BASICS: Time-of-Use Statewide Initiative

WHO? Non-residential customers

WHAT? Time-of-Use rates are determined by when you use energy (time of day, day of week, season) and how much you use.

WHY? Time-of-Use is part of a statewide initiative designed to keep the grid reliable so everyone will have power when they need it.

WHEN? GS-1 and GS-2 customers* will transition to TOU Jan. 2014PA-1 and PA-2 customers* will transition to TOU Feb. 2014*with 12 months of interval data as of July 31, 2013

RATE COMPONETS: Demand (kW) / Energy (kWh)

Power (kW or Demand) is a measure of how quickly work is being done.

Energy (kWh) is a measure of how much work was done

Car Example

The speedometer measures the rate at which work is being done - your Speed is like Kw

The odometer measures how much work was done - Miles driven is like kWh

1kW = 1.341 Horsepower

1 kWh = Ten 100 watt light bulbs running for 1 hour

Watts is a unit of power

kW = 1000 Watts (kilo is 1000 times)

15 minute Demand Interval

9kW

comes on

9kW shuts

off

0 – 5 minutes: 9 kW x 1/3 of time = 3 kW avg.

DEMAND EXAMPLE

5 – 10 minutes: 30 kW x 1/3 of time = 10 kW avg. 10 – 15 minutes: 21 kW x 1/3 of time = 7 kW avg.

Total = 20 kW avg.

• Measured Demand is an average demand over a 15 minute interval

9

Typical Rate Schedules (Comm/Ind.)

• TOU-8-B (Options A and B)– Maximum Demand Greater than 500kW– Facilities-Related & Time-Related Demand Charge– Energy Charge (based on Peak Period)

• TOU-GS-3 (Options A and B)– Maximum Demand Between 300kW and 499kW

• TOU-GS-2 (Options A and B)– Maximum Demand Between 20kW and 299kW)

• TOU-GS-1 (Options A and B)– Maximum Demand Between 0kW and 19kW)

10

Typical Rate Schedules (Ag/Pumping)

• TOU-PA-3 (Options A and B)– Maximum Demands Between 300kW and 499kW)

• TOU-PA-2 (Options A and B)– Maximum Demands Beetween 20kW and 299kW)

• TOU-PA-1 (Options A and B)– Maximum Demands Between 0kW and 19kW)

• TOU-PA-2-RTP & TOU-PA-3 (Real Time Pricing)– Temperature-based rate, hourly pricing– Based on temperature recorded at LA Civic Center

• TOU-PA-SOP (Super-Off Peak)– Beneficial to Customers Who Confine Majority of Usage to SOP Period

How Time-Of-Use Rates Work

With Time-of-Use rates, the cost of electricity changes depending on the time of day you use it. Instead of a single flat rate for electricity use, the cost of electricity on a Time-of-Use rate varies based on the time of day, day of week, and season in which it is used. With Time-of-Use rates, when you use electricity is just as important as how much you use.

• Departing Load (DL) tariffs apply to self-generation customer load that departed from SCE on or after 12/20/1995, with several exceptions. 1. DL tariffs pay for costs of Public Energy Policies.2. Schedule DL-NBC (Departing Load NonBypassable) applies to load that

departed on or after 12/20/1995.• Rate components: Nuclear Decommissioning Charge (NDC), Public Purpose

Programs Charge (PPPC), and Competition Transition Charge (CTC).

3. Schedule CGDL-CRS (Customer Generation Departing Load – Cost Responsibility Surcharge) applies to load that departed after 02/01/2001, in addition to DL-NBC.• Rate components: Department of Water Resources (DWR) Bond Charge,

Competition Transition Charge (CTC), and Power Charge Indifference Adjustment (PCIA).

• Exemptions from Departing Load1:1. “Net Energy Metering Eligible” generators – e.g. Solar and Wind or Fuel

Cells ≤ 1 MW2. Co-Generators1 are exempt from the CTC rate component, (PUC 372 and/or 374)

3. CSI and SGIP Eligible1 generators are exempt from CGDL-CRS for the first 1 MW only

4. Generators1 that meet BACT standards set by AQMD and/or CARB are exempt from PCIA rate component

• DL is determined based on either the actual kWh output of the generator or a calculated estimate. 1. Calculated DL = Mo. Avg. kWh (over 12 months prior to Gen Ops) – less Current

Month’s kWh

Note 1: After State-wide Cap has been reached, CRS charges apply.

Departing load charges and when are they applicable or not.

• Standby (SB), Schedule S, is required for all customers who self-generate all or part of their site load, with a few exceptions.

• Permanent Exemptions for both SB & DL:1. “Net Energy Metering Eligible” generators – e.g. Solar and Wind or Fuel

Cells ≤ 1 MW2. Backup/Emergency generators – operates only when there is a utility

outage

• Standby contract has two (2) demand level selections:1. Supplemental Contract Capacity (SCC) kW = the Site Load that

SCE will serve when the generator is normally operating or normally not scheduled to operate, e.g. night time.

• SCC kW is used in splitting the Summer On-Peak kW and Mid-Peak KW between Supplemental and Back-up Time Relate Demand for customers that do not have a SCE generator output meter

2. Standby Demand (SB) kW = the load that the generator regularly serves and SCE is expected to instantaneously provide when the generator goes down, excluding any SCC .

• SB can not be more than the Generator Size nor Site Load; it excludes any SCC

• SB kW is used in offsetting the maximum demand in determining excess FRD

Standby charges and when are they applicable or not

– Do these charges vary based on the type of rate structure the facility is currently on?• Yes, similar to TOU, it is based on the site’s

– Maximum Demand level (≤20, 21-199, 200-500, >500 kW), and– Service Voltage (<2, 2-50, 51-219, >220 KV). – The higher these values, the rates tend to be lower.

• SB’s Capacity Reservation Charge is a monthly fixed amount based on the SB kW and charged regardless of monthly maximum demand

– Are facilities with on-site generation in any way limited in their rate structure options?• Yes, they are limited to only Option B, (and TOU-S-RTP); i.e. no

Option A, R or CPP• And they are also limited to TOU-BIP in the Demand Response

programs.

Do these charges vary and have limitations?

SOLUTIONS: No-cost, Low-cost

NO-COST TEMPORARY REDUCTION TIP CHECKLISTWhere possible, shift operations to maximize lower cost time periodsStagger equipment use to minimize demandWhen you do not need all your pumps operating, use lower cost pumps first Plan your irrigation sets to maximize weekends and lower cost time periods.For seasonal operations, know the start of your billing periodMake sure time clocks are set properly

PERMANENT REDUCTION TIPS

Use Variable Speed Drives (VSDs) instead of a valve to control flowLow Pressure Sprinkler NozzlesVSDs on Dairy Vacuum and Milk PumpsControls for fansInstall time clocks, sensors, to avoid higher cost periods
