Goderich A-CAES Facility

About the project

The Goderich A-CAES Facility, located in Goderich, Ontario, Canada, is the world’s first commercially contracted Advanced-CAES facility. The plant is contracted by Ontario’s Independent Electricity System Operator (IESO) for peaking capacity, ancillary services, and full participation in the merchant energy market to support grid reliability. Entirely fuel-free, the plant produces zero greenhouse gas emissions, and helps enable a cleaner, more affordable, and more flexible electricity grid.

With 1.75 megawatts (MW) of peak power output; a 2.2 MW charge rating; and 10+ megawatt-hours (MWh) of storage capacity, this achievement is a first-of-its-kind utility-scale commercial application of A-CAES technology, conforming to all interconnection, uptime, performance and dispatch standards as set out by the IESO. The facility proves out the ability of Hydrostor’s A-CAES technology to fully participate in and deliver a range of valuable grid services to electricity markets.
