The Elora and Hedley projects together feature a total installed capacity of 420 MW / 2,122 MWh, adding substantial new storage capacity to Ontario’s power grid. They will become among the largest energy storage facilities currently under development in the province. This collaboration further strengthens Ontario’s leadership in large-scale energy storage deployment and highlights the deepening partnership between Canadian Solar’s e-STORAGE and Aypa Power in advancing key energy infrastructure across North America.

Both projects will utilize Canadian Solar’s SolBank, a large-scale energy storage system. According to the plan, equipment delivery will begin in Q1 2026, and commercial operation is expected to start in the first half of 2027.

Upon completion, e-STORAGE will provide comprehensive 20-year operations and maintenance (O&M) services under the signed Long-Term Service Agreement (LTSA). These services include continuous monitoring, preventive maintenance, and performance assurance, ensuring the system’s safe, reliable, and efficient operation throughout its lifecycle while securing long-term, stable service returns.
