Each of California’s three major investor-owned utilities, Southern California Edison (SCE), Pacific Gas and Electric (PG&E) and San Diego Gas & Electric (SDG&E), offer the Base Interruptible Program (BIP). BIP is a tariff based, emergency-triggered demand response program that the California Independent System Operator (CAISO) can dispatch for system emergencies, and the utilities can dispatch for local emergencies. Customers enrolled in BIP receive incentive payments in exchange for committing to reduce their electrical usage to a contractually-established level referred to as the Firm Service Level (FSL). Participants who fail to reduce their load to their FSL are subject to a financial penalty assessed on a kW per hour basis. Enrollment in BIP in January 2010 equaled 188 accounts for PG&E, 650 accounts for SCE and 19 accounts for SDG&E.
