250 MW/1000 MWh Battery storage project awarded in Canada

Ameresco, Inc, in partnership with Atura Power, a subsidiary of Ontario Power Generation, has been selected by the Independent Electricity System Operator (IESO) in Canada to build and operate a 250 MW, 1,000 MWh battery energy storage system (BESS) project. 

Ameresco and Atura Power will complete the project through a joint venture (JV) known as the Napanee BESS Inc. Pursuant to the award, the JV will enter into a 20 year capacity agreement with the IESO. In addition to being a 10.1% minority partner in the Napanee BESS Inc. JV, Ameresco will provide Engineering and Construction (E&C) solutions and expertise for the installation of the BESS under a separate contract with the JV.

The IESO expects that Ontario will have at least 1,217 MW of energy storage capacity, up from 228 MW currently, participating in the IESO’s electricity market by 2026 as a result of this project and other similar storage installations.
