e-STORAGE to Deliver 1.86 GWh DC of Energy Storage Solutions for the Skyview 2 Project Ontario
November 12, 2025
Construction is now underway on the new Skyview 2 Battery Energy Storage System, which will provide enough capacity to power nearly 400,000 homes, strengthening the province’s electricity grid.
The project, developed by Potentia Renewables in collaboration with the Algonquins of Pikwàkanagàn First Nation, was awarded under Ontario’s Long-Term Reliability (LT1) energy storage procurement process.
“On behalf of the Algonquins of Pikwakanagan First Nation, I want to thank our partners at Potentia, our project team and all those who have supported this important work”, said Chief Greg Sarazin of the Algonquins of Pikwakanagan First Nation. “Together, we are showing that when First Nations are included as full participants in Canada’s energy landscape, everyone benefits. Chì Mìgwech. Thank you.”

e-STORAGE has been contracted to provide a fully integrated energy storage solution and turnkey Engineering, Procurement, and Construction (EPC) services for the 411 MW/1,858 MWh Skyview 2 Energy Storage Project in Edwardsburgh Cardinal, Ontario, Canada.
As the turnkey EPC provider, e-STORAGE will deliver approximately 390 units of its proprietary SolBank 3.0 energy storage solution for the project. Shipments are expected to begin in February 2026, with commercial operation planned for the second quarter of 2027. e-STORAGE will also provide system integration, substation and balance-of-plant works (excluding the high-voltage transformer and HV switchgear), as well as the transmission line interconnection to the existing grid infrastructure. Additionally, e-STORAGE will provide a 21-year Long-Term Agreement (LTSA) to ensure long-term system performance and reliability.
With 8 GWh of energy storage projects deployed across North America, e-STORAGE continues to strengthen its execution track record and regional presence. Skyview 2 builds on this momentum and reinforces e-STORAGE’s full-stack delivery capability across the storage project lifecycle.
With electricity demand in Ontario forecasted to increase significantly by 2050, Skyview 2 marks an important milestone in Ontario’s clean energy transition and will play a vital role in supporting the province’s clean electricity grid. Once operational in 2027, the facility will store electricity from Ontario’s clean electricity grid during periods of low demand and return that stored power to the system when demand is higher, while creating up to 300 jobs during construction and additional operational positions following completion.
The Skyview 2 project is a lithium-ion battery energy storage facility procured through the Independent Electricity System Operator’s (IESO) Long-Term 1 Request for Proposals (LT1 RFP). Developed in partnership between Potentia Renewables Inc. and the Algonquins of Pikwakanagan First Nation, the facility builds on other projects such as the Oneida Energy Storage facility, to bring Ontario’s total energy storage capacity to nearly 3,000 megawatts (MW) and collectively create up to 3,000 jobs across the province.
“The Skyview 2 Energy Storage Project represents a major milestone for both Ontario and Potentia, marking the province’s largest battery energy storage project to date. Together with the Algonquins of Pikwàkanagàn First Nation and our partners at Canadian Solar and e-STORAGE, we’re proud to advance innovative, dependable, and affordable energy solutions that enhance grid reliability and deliver lasting value to local communities.”
Ben Greenhouse, CEO, Potentia
“The Skyview project, our largest SolBank delivery contract to date, is set to become one of Canada’s largest battery energy storage facilities upon completion. This project is a strong validation of our full-stack delivery model, which combines our proprietary SolBank technology with turnkey EPC execution to deliver bankable, grid-ready energy storage infrastructure at scale. We are proud to support Potentia and the Province of Ontario in advancing this project in collaboration with the Algonquins of Pikwàkanagàn First Nation, reflecting our commitment to responsible development and long-term community participation. This project will reinforce grid reliability and accelerate Canada’s clean energy transition.”
Colin Parkin, President of e-STORAGE
