![]() The CAISO emergency could be statewide, limited to a local area, called in the day-ahead of event, or day-of event. The CAISO’s AWE declarations process involves multiple stages depending on the timing and severity of the grid’s situation starting from Alert (issued in the day-ahead), Warning, and a Stage 1, 2, or 3 Emergency (issued in real time), per the CAISO Operating Procedure 4420. In December 2021, the CPUC expanded the ELRP for Summers 2022 and beyond to include participation by residential customers.Nearly half of California consumers will be automatically enrolled in the residential program, and the CPUC ordered the IOUs to do special outreach to low-income customers enrolled in the CPUC’s California Alternate Rates for Energy (CARE), the Energy Savings Assistance (ESA), Family Electric Rate Assistance (FERA), as well as households located in Disadvantaged Communities (as defined Health and Safety Code Section 39711).Īn ELRP event is triggered or called by the IOUs only after declaration of a grid emergency by the California Independent System Operator’s (CAISO’s) Alert, Warning, or Emergency (AWE) process, or a CAISO-issued Flex Alert in some cases.The ELRP started in Summer 2021 with nearly 200 megawatts (MW) of enrolled non-residential customer participation.The program was called on four times in the early summer 2021, and customers received payments of approximately $1 million for voluntary reductions in demand achieved through the ELRP.The State’s three IOUs handle customer enrollment, event communication, and per event compensation.The ELRP pays customers who voluntarily reduce electricity demand during a grid emergency.The ELRP Program is called upon only as a last resort during an emergency grid situation issued by the California Independent System Operator (CAISO).The ELRP is managed by the State’s three large investor-owned utilities (IOUs) - Pacific Gas & Electric, San Diego Gas & Electric, and Southern California Edison.The purpose of the ELRP pilot is to offer a new tool for the electric grid operators and utilities for reducing energy consumption during a grid emergency to reduce the risk of electricity outages when the available energy supply is not sufficient to satisfy the anticipated electricity demand. The ELRP is a 5-year pilot program designed to pay electricity consumers for reducing energy consumption or increasing electricity supply during periods of electrical grid emergencies.
