Projects

We have two projects under advanced development, the 200 MW Silver City Energy Storage Centre in Australia, and the 500 MW Willow Rock Energy Storage Center in California.

With a growing 7 GW Pipeline, these projects build off the success of our 2 MW Goderich Energy Storage Centre, the worlds first commercially contracted Advanced Compressed Air Energy Storage facility that is operating in Canada.

Hydrostor’s 7 GW Pipeline

Hydrostor has a growing pipeline of projects totaling over 7,000 MW globally. Other markets Hydrostor is actively pursuing projects include California, Arizona, New York, Nevada as well as sales to utilities in the Southeast and Northwest of the U.S.; Canadian provinces including Ontario, Alberta, and Newfoundland; and Australian states including New South Wales, South Australia, and Victoria.

Given the siting flexibility of the A-CAES technology, and based on the growing LDES needs globally, Hydrostor expects to have a presence in many of these markets as they establish their LDES policies.

Early-Stage Developments

In addition to our Silver City development, Hydrostor is engaged in early-stage development activities. We are working with local stakeholders in Wellington, NSW, to advance a 500 MW / 16-hour energy storage facility that will help NSW meet its legislated energy storage targets, which explicitly include long-duration energy storage.

Hydrostor is exploring two 500 MW early-stage development opportunities in western and south-west Victoria, in response Victoria’s 95 percent renewable energy target by 2035. Long duration energy storage will provide high levels of grid reliability in a variable renewables energy system.

Hydrostor is seeking to develop a 500 MW A-CAES facility in South Australia’s Cultana/Whyalla region. We are working closely with the SA government to advance a project that will assist the state in meeting its reliability standards and deliver much needed long duration energy storage.

Hydrostor is engaged in early-stage development activities, working with local officials and stakeholders, in New York’s Lewis County. We are working to advance a 500 MW energy storage facility in order to participate in NYSERDA’s long-duration procurement to help New York meet its long duration energy storage targets.

Hydrostor is advancing development opportunities in Arizona’s Maricopa County for a 500 MW long-duration energy storage facility that can respond to Arizona’s reliability needs and projected demand growth.

Hydrostor is in the early stages of exploring commercial pathways for the development of a 500 MW long duration energy storage A-CAES project in Nevada. We are executing on early-stage development activities, including geological assessments, to be able to respond to opportunities in Nevada and surrounding states.

California has identified the need for significant long duration energy storage (8+ hours) in their integrated resource plan modelling. Hydrostor is exploring an opportunity to develop a 500 MW facility in Southern California that will interconnect into the California Independent System Operator (CAISO) grid as part of the Cluster 15 process. The Chronos Energy Storage Center Project is expected to connect via the Lugo Substation in San Bernardino County.

Hydrostor also has an active queue position with LADWP that is currently contemplated to be used for an additional project in Kern County, if approved.

Hydrostor is exploring the development of a 500 MW energy storage centre targeting Window 2 of the British government’s LDES Cap & Floor procurement pathway. Hydrostor has advanced early development activities, including submitting interconnection applications, while awaiting further details from Government on an anticipated Window 2 in early 2026.

500 MW - A-CAES Generic Rendering
01

Quinte Energy Storage Centre

The Quinte Energy Storage Centre (Quinte ESC) is an Advanced Compressed Air Energy Storage (A-CAES) project under development in Lennox and Addington County. Strategically located adjacent to the Lennox Transformer and Generating Stations, the project is positioned to support the electrical grid reliability of the region for decades to come.

Two sites are currently being assessed for development: the West Site is in Greater Napanee and the East Site in Loyalist Township. Both sites are being evaluated in parallel, with the initial phase targeting 500 MW of capacity and additional phases targeting between 1,000-2,000 MW.

Silver City Energy Storage Centre

Silver City is a 200 MW Advanced Compressed Air Energy Storage (A-CAES) facility that is under late-stage development in Broken Hill, New South Wales. The project provides unmatched benefits to consumers in a remote region with extensive renewable infrastructure and resources.

Willow Rock Energy Storage Center from above
04

Willow Rock Energy Storage Center

Willow Rock is a 500 MW Advanced Compressed Air Energy Storage (A-CAES) facility that is under late-stage development in California. As California moves towards its objective of achieving 100% carbon-free electricity by 2045, it will require large-scale, long duration energy storage to fully integrate increasing levels of renewable generation capacity.
