DECEMBER 19, 2025<\/strong> \u2013 Hydrostor, a leading global long duration energy storage (LDES) developer and operator, is pleased to announce that the Willow Rock Energy Storage Center received final permitting approval<\/a> from the California Energy Commission (CEC), positioning the project to be shovel-ready in 2026. The 500 MW \/ 4,000 MWh advanced compressed air energy storage (A-CAES) project can store energy for eight hours of continuous discharge to the grid, and will provide reliability and resiliency amidst rapidly rising electricity demand.<\/p>\n\n\n\n

\u201cThis permit from the CEC is a crucial milestone to realizing the benefits of the Willow Rock project, and helps to unlock the rest of our multi-gigawatt pipeline in North America. We\u2019re appreciative of all the work that has gone into reaching this important milestone,\u201d said Curtis VanWalleghem, Hydrostor Co-Founder and CEO. \u201cOur A-CAES technology will be key to reliably meeting expected demand increases driven in part by data centers and AI, while also maintaining affordability for existing customers. We\u2019re excited to show the world the benefits A-CAES can bring to the grid.\u201d<\/p>\n\n\n\n

Jon Norman, Hydrostor President, said, \u201cWe\u2019re grateful to the Commissioners, CEC staff, and all of our community stakeholders for the work that went into permitting the Willow Rock Energy Storage Center, which will be a critical economic driver for Kern County and the surrounding region. Now, we\u2019re eager to get to work bringing the project to life, creating thousands of jobs and enhancing energy reliability and resiliency.\u201d<\/p>\n\n\n\n

Strategically located in Kern County, Hydrostor\u2019s innovative storage technology stores surplus energy, which it is then able to discharge during peak use hours. The project will be able to power more than 400,000 homes for more than eight hours and will bring more than $500M in investment to the East Kern County and the greater Antelope Valley, in addition to thousands of jobs during construction and 40 full-time jobs for its 50-year operational lifetime.<\/p>\n\n\n\n

The project received its franchise agreement from the Kern County Board of Supervisors as of early December, and received a conditional letter of support also from the Kern County Board of Supervisors in April.<\/p>\n\n\n\n

The Willow Rock Energy Storage Center is Hydrostor\u2019s first utility-scale project being built in the U.S. The company is developing another late-stage project in New South Wales, Australia, and has a 7 GW project pipeline globally, with projects in the U.S., Australia, Canada, and the UK.<\/p>\n\n\n\n
