The Center for Sustainable Energy, along with project partners Tesla and Olivine, demonstrated the ability to bid five behind-the-meter (BTM) energy storage systems into the California Independent System Operator (CAISO) wholesale energy and ancillary service markets.
This opens opportunities for increasing the value of commercial-scale BTM energy storage battery installations by generating revenue through participating in wholesale price markets and supporting distribution system reliability. Specifically, the batteries participated in the day-ahead energy market, the real-time energy market and the spinning reserves segment of the ancillary services market and simulated the provision of frequency regulation.
The research was supported by a grant from the California Energy Commission’s Electric Program Investment Charge (EPIC) program.
