1 TIME OF USE RATES EDUCATION & OUTREACH FOR AGRICULTURAL & PUMPING CUSTOMERS SCAP ENERGY MANAGEMENT COMMITTEE MEETING AUGUST 12,

2 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 PA-1 and PA-2 customers* will transition to TOU Feb *with 12 months of interval data as of July 31,

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

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

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 = 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) 7

8 15 minute Demand Interval 9kW additional 21kW 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 8

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) 9

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 10

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. 13

14 SM SOUTHERN CALIFORNIA EDISON® Business Customer Division Standby and Departing Load (SB&DL) Response to Questions for Roundtable Discussion on Electricity Rates SCAP Energy Management Committee Meeting August 12, 2014 Project Management Technical Services B. Emerson, Sr. Project Manager DRAFT

15 SM Slide: 15 SOUTHERN CALIFORNIA EDISON® Business Customer Division Project Management Technical Services 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 Load 1 : 1.“Net Energy Metering Eligible” generators – e.g. Solar and Wind or Fuel Cells ≤ 1 MW 2.Co-Generators 1 are exempt from the CTC rate component, (PUC 372 and/or 374) 3.CSI and SGIP Eligible 1 generators are exempt from CGDL-CRS for the first 1 MW only 4.Generators 1 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.

16 SM Slide: 16 SOUTHERN CALIFORNIA EDISON® Business Customer Division Project Management Technical Services 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 MW 2.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

17 SM Slide: 17 SOUTHERN CALIFORNIA EDISON® Business Customer Division Project Management Technical Services –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, , , >500 kW), and –Service Voltage ( 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?

18 SOLUTIONS: No-cost, Low-cost  NO-COST TEMPORARY REDUCTION TIP CHECKLIST Where possible, shift operations to maximize lower cost time periods Stagger equipment use to minimize demand When 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 period Make sure time clocks are set properly  PERMANENT REDUCTION TIPS Use Variable Speed Drives (VSDs) instead of a valve to control flow Low Pressure Sprinkler Nozzles VSDs on Dairy Vacuum and Milk Pumps Controls for fans Install time clocks, sensors, to avoid higher cost periods Visit sce.com/EnergyTips for more customized tips and information by business type. 18
