First Offtake Deal Signed For 500MW/4,000MWh Advanced Compressed Air Energy Storage Project In California

The title of this post, is the same as that of this article on Energy Storage News.

These three paragraphs explain the deal.

Advanced compressed air energy storage (A-CAES) company Hydrostor has signed a power purchase agreement (PPA) for one of its flagship large-scale projects in California.

Central Coast Community Energy, one of California’s several dozen Community Choice Aggregator (CCA) non-profit energy suppliers, has signed a 200MW/1,600MWh energy storage PPA with a 25-year term with Toronto-headquartered Hydrostor for its Willow Rock Energy Storage Center.

That’s just under half of the output and capacity of the planned 8-hour, long-duration energy storage (LDES) facility, which is designed to be 500MW/4,000MWh. This is its first offtake deal, but the company is in discussion for others to take the rest of the plant’s available resource.

The article says that Hydrostor aim to have the plant online by 2028.

This segment describes their current projects.

It is currently working on large-scale projects with around 9GWh storage capacity in total across two sites in California as well as another in Australia.

Together with Willow Rock in Kern County, Hydrostor is developing the 400MW/3,200MWh Pechos Energy Storage Center in San Luis Obispo County, California, and the 200MW/1,500MWh Silver City Energy Storage Center in Broken Hill, New South Wales, Australia.

On its UK Projects page, Highview talks about a 200MW/2.5GWh facility in Yorkshire, which puts the two companies in similar markets, with Hydrostor appearing to have slightly larger systems under development.

Conclusion

It will be interesting to see how this technology progresses and which company does best in what is a very large energy storage market.
