Appendix F‐1. PG&E’s Demand Response Programs (2010)
Residential Programs
Residential SmartAC. PG&E will install a free SmartAC device that will be connected to a customer’s air conditioner (AC). Between May 1 and October 31, if there is an energy supply emergency, the SmartAC device will receive a signal to use slightly less power to avoid a power interruption
Commercial, Industrial, and Agricultural Programs
Peak Day Pricing (E‐PDP). Allows participants to lower their business' electric bills by shifting or reducing electricity during critical peak summer afternoons (noon to 6 p.m. ). Participants receive day‐ahead notification and program takes place only 12 days during each summer season. Will be the default option for customers larger than 200 kW.
SmartAC. PG&E will install a free SmartAC thermostat to help manage heating and cooling needs year round. If a business has an energy management system in place, PG&E will install a free SmartAC “switch.” If there is an energy supply emergency, between May 1 and October 31, the SmartAC device will receive a signal to use slightly less power to help avoid power interruptions.
Base Interruptible Program (E‐BIP). Pays participants to reduce their load to a pre‐determined level when the CAISO calls a load curtailment notice. Must commit to curtail at least 15% of average monthly load or a minimum of 100 kW, whichever is greater. Two options available.
Demand Bidding Program (E‐DBP). Allows participants to submit bids for a proposed level of load reduction at an offered price for each curtailment event. Participants must commit to reduce a minimum of at least 50 kW. Bids may be requested on a 'Day‐Ahead' basis when an CAISO's Alert notice is issued for the next day or when the CAISO's forecasts a day‐ahead peak demand of 43,000 MW or greater.
Scheduled Load Reduction Program (E‐SLRP). Participants identify one to three four‐hour time periods during the week when they are willing to curtail their electric load. Must commit to curtail at least 15% of their average monthly load or a minimum of 100 kW, whichever is greater. Must curtail electric load once each week for each period they choose during the summer season, June 1 through September 30. Loads cannot be shifted to an on‐peak period of another day.
Optional Binding Mandatory Curtailment Plan (OBMC).Lets participants avoid curtailments by implementing load reductions of 5% to 15% increments on their entire circuit or dedicated substation during rotating outages.
Aggregators Programs. Pools resources of a group of customers to achieve higher demand reductions with unique incentive structures. Acting as intermediaries between businesses and PG&E, aggregators offer demand response program options not available through PG&E. Aggregators are independent third parties authorized to work with PG&E to reduce the state's energy usage during periods of peak demand, high wholesale‐electrical prices, system
constraints, and emergencies.
