California energy storage subsidy extension signed into law


While it ended four weeks ago, in terms of clean energy this year’s highly consequential session of the California legislature actually came to a close yesterday, with Governor Jerry Brown (D) giving his signature to what solar and energy storage advocates consider to be a key piece of policy: a five-year extension of the Self Generation Incentive Program (SGIP).

As expressed in private at the Solar Power International conference, advocates were getting legitimately concerned as to whether or not the governor was going to actually sign SB 700. However, yesterday the governor obliged.

California Solar and Storage Association (CALSSA) estimates that this will mean an additional $800 million in subsidies for batteries and other forms of energy storage, which will deliver 3 GW of additional behind-the-meter storage.

SGIP has been a key support for battery installations at homes, schools and non-profit organizations in California, and CALSSA Executive Director Bernadette Del Chiaro notes that the subsidy program is critical to support the state’s solar market as well, given the shift to mandatory time of use rates under the Net Metering 2.0 program.
