CalReady is a virtual power plant (VPP) program in which its solar and energy storage customers agree to enroll their batteries to dispatch power during peak electricity demand events in exchange for compensation. Customers are paid up to $150 per battery enrolled in the program. California has the largest residential storage market in the US and the densest stack of programs that pay you for owning a battery. SGIP funds the purchase; DSGS, ELRP, and aggregator VPPs pay for the dispatch. The California stack, in plain order. The state's four major programs — DSGS, ELRP, SGIP-VPP, and utility-specific options like Tesla-PG&E and SMUD's My Energy. That's when PG&E, SCE, and SDG&E tapped 100,000 residential storage batteries installed by Tesla and Sunrun to form a first of its kind VPP — virtual power plant. In all, those batteries supplied about 535 megawatts of electricity to the grid — enough to supply the electrical needs of hundreds of. An aggregation of more than 100,000 residential batteries provided an average 535 MW of support to California's electricity grid during a test to prepare for the hot summer period ahead. California homeowners with batteries could soon get paid for sharing stored energy during peak demand, if a bill working its way through the state. VPP Earnings Are Real and Significant: California homeowners with Tesla Powerwall or compatible batteries earn $300-$500 annually through DSGS or $200-$600 through ELRP programs, with one documented case earning $574.
