  5. Traditional Summer Time Periods SEASONAL: Traditional Time Periods Traditional Winter Time Periods Highest Energy Charge Medium Energy Charge Lowest Energy Charge Medium Energy Charge Lowest Energy Charge Three different TOU periods: Holidays: • Holidays are considered Off-Peak or Super Off-Peak. When any holiday falls on a Sunday, the following Monday is recognized as the holiday On-Peak: Highest Energy Charge Mid-Peak: Medium Energy Charge Off-Peak: Lowest Energy Charge

  6. TIME PROFILE: Standard TOU Rate % Time / Number of Hours Average per Month

  7. 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)

  8. DEMAND EXAMPLE • Measured Demand is an average demand over a 15 minute interval 15 minute Demand Interval additional21kW comes on 9kW shuts off 9kW 0 – 5 minutes: 9 kW x 1/3 of time = 3 kW avg. 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.

  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

  13. 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.

  14. Standby and Departing Load(SB&DL)Response to Questions for Roundtable Discussion on Electricity RatesSCAP Energy Management Committee MeetingAugust 12, 2014 Project Management Technical Services B. Emerson, Sr. Project Manager DRAFT

  15. Departing load charges and when are they applicable or not. • Departing Load (DL) tariffs apply to self-generation customer load that departed from SCE on or after 12/20/1995, with several exceptions. • DL tariffs pay for costs of Public Energy Policies. • 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). • 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: • “Net Energy Metering Eligible” generators – e.g. Solar and Wind or Fuel Cells ≤ 1 MW • Co-Generators1are exempt from the CTC rate component, (PUC 372 and/or 374) • CSI and SGIP Eligible1generators are exempt from CGDL-CRS for the first 1 MW only • 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 calculatedestimate. • 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.

  16. Standby 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 bothSB & DL: • “Net Energy Metering Eligible” generators – e.g. Solar and Wind or Fuel Cells ≤ 1 MW • Backup/Emergency generators – operates only when there is a utility outage • Standby contract has two (2) demand level selections: • 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 • 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

  17. Do these charges vary and have limitations? • 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.
