Canadian Solar Inc. announced that e-STORAGE, part of its majority-owned subsidiary CSI Solar Co., Ltd. (“CSI Solar”), has signed Battery Storage Agreements (BSA) and Long-Term Services Agreements (LTSA) with Aypa Power for the Elora and Hedley battery energy storage projects in Ontario, Canada.

Together, the Elora and Hedley projects will deliver 420 MW / 2,122 MWh of new storage capacity to Ontario’s grid, making them among the largest energy storage facilities currently under development in the province. The projects highlight Ontario’s growing role in large-scale energy storage deployment and reflect the ongoing collaboration between e-STORAGE and Aypa Power to expand critical energy infrastructure across North America.

Moe Hajabed, CEO of Aypa Power, said in a statement, “The Elora and Hedley projects represent critical investments in Ontario’s energy system, providing the flexible capacity needed to meet rising demand and maintain a reliable grid. By working with trusted partners and applying the highest standards in performance and safety, we are building assets that deliver lasting value to Ontario’s communities and economy.”

Colin Parkin, President of e-STORAGE, also added, “We are proud to expand our partnership with Aypa Power through the Elora and Hedley projects. These projects will provide reliable capacity through the IESO’s Long-Term 1 (“LT1”) Resource Adequacy framework and reaffirm our long-term commitment to the Canadian market.”

Both facilities will utilize e-STORAGE’s SolBank product under 20-year LTSAs that include continuous monitoring, preventive maintenance, and performance guarantees. These agreements are designed to ensure high system availability and provide predictable service revenues over the lifetime of the assets. Delivery is planned to begin in the first quarter of 2026, with commercial operations expected in the first half of 2027.
