Demand Response Auction Mechanism (DRAM)


The California Public Utilities Commission (CPUC or the Commission) approved SDG&E, and other Investor Owned Utility (IOUs), to offer a two-year DRAM pilot to the third party aggregators to participate directly in the California Independent Operator System (CAISO) market comprising customers in the SDG&E’s service territory.  Later the Commission issued decision D.16-06-029 to extend the DRAM pilot into 2018 and 2019. Any SDG&E customer, whether they receive commodity service from SDG&E or another Energy Service Provider, is eligible.  Currently the DRAM program is in its second year and is offered by the selected third party aggregators (listed below) for delivery starting in the whole year of 2017.

SDG&E Electric Rule 32 governs how SDG&E interacts with third party Demand Response Providers (DRPs). The Commission, in D.15-03-042, followed by D. 16-06-008, authorized SDG&E to put into place certain processes and systems to facilitate third party DRPs' ability to bid demand response resources into the CAISO wholesale market through Proxy Demand Resources (PDRs) and Reliability Demand Response Resources (RDRRs). The DRAM program is subject to the provisions of Rule 32 which establishes certain processes, time frames and volume limits, plus any additional limitations authorized by the Commission. Currently with the implementation, the Commission has approved SDG&E’s limitation up to 30,000 customer market registrations for DRAM.
