Emergency Load Reduction Program (ELRP) Data and Information
This page serves for Emergency Load Reduction Program (ELRP) data and information. For details about program parameters and how to participate in ELRP, please go to the main ELRP webpage here.
In 2021, the California Public Utilities Commission (CPUC) created an innovative program, the Emergency Load Reduction Program (ELRP), to pilot a new Demand Response approach to help avoid rotating outages during peak summer electricity usage periods from May thru October. The ELRP started in 2021 with commercial customer participation. In December 2021, the CPUC expanded the program to include residential customers for Summer 2022 and beyond.
ELRP Performance and Dispatch Data
ELRP has been dispatched multiple times in summers of 2021, 2022, and 2023, lowering electricity demand statewide during critical conditions when the state needs it most. Data concerning these dispatches can be found below.
