6 FAQs about [Energy storage replaces substation]
Are California's battery energy storage systems going up?
For Immediate Release: October 24, 2023 SACRAMENTO — New data show California is surging forward with the buildout of battery energy storage systems with more than 6,600 megawatts (MW) online, enough electricity to power 6.6 million homes for up to four hours.
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.
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.
Does PG&E have a battery energy storage contract?
PG&E now has contracts for battery energy storage systems totaling more than 3,330 MW of capacity being deployed throughout California through 2024. To date, 955.5 MW (of the 3,330 MW under contract) of new battery storage capacity has been connected to California’s electric grid including:
Is short-duration energy storage cost-effective?
Without further cost reductions, a relatively small magnitude (4% of peak demand) of short-duration (energy capacity of 2-4 hours of operation at peak power) storage is cost-effective in grids with 50-60% of electricity supply that comes from VRE generation.
Does energy storage duration affect gas displacement?
Given the importance of energy storage duration to gas capacity substitution, the study finds that longer storage durations (the amount of hours storage can operate at peak capacity) of eight hours generally have greater marginal gas displacement than storage with two hours of duration.
