Ameresco in partnership with Atura Power, a subsidiary of Ontario Power Generation, by the Independent Electricity System Operator (IESO) in Canada, has been selected to build a 250-megawatt, 1,000-megawatt-hour battery energy storage system (BESS).
Ameresco and Atura Power will complete the project through a joint venture known as the Napanee BESS. Pursuant to the award, the joint venture will enter into a 20-year capacity agreement with the IESO. In addition to being a 10.1 percent minority partner in the Napanee BESS joint venture, Ameresco will provide engineering and construction solutions and expertise for the installation of the BESS under separate contract with the joint venture.
The IESO expects that Ontario will have at least 1.22 gigawatts of energy storage capacity, up from 228 megawatts currently, participating in the IESO's electricity market by 2026 as a result of this project and other similar storage installations.
