Goderich Energy Storage Centre is our first commercial A-CAES facility
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 utility-scale commercial application of A-CAES technology is a significant achievement, conforming to all interconnection, uptime, performance and dispatch standards as set out by the IESO.
Hydrostor’s Goderich energy storage 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.
