SEMINAR: 2025 California Demand Response Potential Study: Data-driven modeling of distributed energy resources to inform public policy

Seminar Abstract 

Demand response (DR) is evolving from a rarely-used peak load shedding concept to a dynamic and multi-function service that can facilitate integration of renewable generation into the electric power system. This talk will be a synthesis of the 2025 California Demand Response Potential Study, an LBNL-led effort to support the California Public Utilities Commission in their development of statewide energy planning and operations policy. We found there are significant opportunities for DR to provide value to the future power system by shedding load at peak times to support local and neighborhood-scale operations, by shifting the timing of loads to capture mid-day solar surplus, and by providing fast responses to second- and minute-time-scale disturbances. Overall, I will describe how we designed and implemented the study to help inform the choices among complementary and sometimes competing technology options that are faced in the process modernizing the power system. The study broke new ground analytically in three areas: 1) It is based on high resolution load data (over 200k SmartMeter load shapes), which has not traditionally been the case for models supporting public policy. 2) We developed a taxonomy of advanced DR resources (with categories called “Shape, Shift, Shed, & Shimmy”) that is both tractable for large-scale modeling and understandable for policymakers. 3) We developed a technique for estimating supply curves of DR resources that enables fair comparison with flexibility alternatives.
