CEC Solar Energy Storage

Why did the CEC get funding for a long-duration energy storage project?

The funding grew out of a solicitation for demonstration and deployment projects that could speed up commercialization of long-duration energy storage technologies while improving grid reliability and resilience for disadvantaged and low-income communities and California Native American tribes, according to the CEC.

Does the California Energy Commission make a warranty on solar equipment?

The California Energy Commission makes no claim or warranty on the equipment and its safety, performance, or durability. Submitted information is reviewed by the California Energy Commission prior to equipment being added to the Energy Commission's Solar Equipment Lists, manufacturers’ self-reported information is not confirmed.

Where can I find a list of solar equipment?

To view listed equipment or download a copy of the active PV Module, Inverter, Energy Storage System (ESS), Battery, Meter, or Power Control System (PCS) lists please visit the Energy Commission’s Solar Equipment Lists application.

How do energy storage projects work?

Energy storage projects capture power produced by wind and solar resources and discharge the energy back to the electric grid during times of peak demand. In California, electricity demand is highest in the late afternoon and early evening hours when the sun sets, causing solar resources to drop off before winds pick up later in the evening.

Why are California's energy storage grants important?

“These grants are really putting a marker around California’s commitment to ensuring we’re going to get long-duration energy storage to complement battery storage on the grid to meet our goals,” CEC Commissioner Patty Monahan said during the agency’s June 12 meeting.

How many MW of energy storage capacity is needed by 2045?

The state is projected to need 52,000 MW of energy storage capacity by 2045 to meet electricity demand. “Energy storage systems are a great example of how we can harness emerging technology to help create the equitable, reliable and affordable energy grid of the future,” said CEC Vice Chair Siva Gunda.
