In 2022, California experienced a heat dome event, which caused protracted high temperatures throughout the state. This event created life-threatening conditions for millions and produced significant grid constraints. In response, energy storage proponents touted the success of behind-the-meter (BTM) energy storage in providing customer resiliency and peak demand relief during the event. Considerable potential exists for BTM storage to deliver demand reductions, with over 1,000 MW of BTM residential storage power installed in California. The question of what percentage of that capacity is already being dispatched for customer TOU arbitrage or self-consumption versus what incremental capacity can be drawn from these systems in the event of another heat dome event remains. This presentation will help answer some of these questions with knowledge of how storage incentivized through the Self-Generation Incentive Program (SGIP) was performing during that event, along with an understanding of how non-program storage is being utilized regularly.
