“As part of our plan to protect Ontario, we’re making record investments in energy generation, transmission and storage to make our province an energy superpower,” said Premier Doug Ford. “Skyview 2 is an important part of that plan and will be a game-changer for Leeds and Grenville’s economy, as well as our First Nations partners. It will help to deliver the reliable, clean and affordable energy needed to power our growing communities and economy for generations to come.”

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.

“Ontario is building big and for future generations as we lead the largest nuclear and energy storage expansion in Canadian history,” said Stephen Lecce, Minister of Energy and Mines. “With shovels in the ground on Canada’s largest battery storage facility, our government is proud to support Canadian workers, Indigenous communities and affordability for all Ontarians.”

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.

“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.”

Building the largest battery storage fleet in the country is a key pillar of Energy for Generations, Ontario’s long-term roadmap to deliver reliable, affordable and secure energy to power the most competitive economy in the G7. The plan also underscores the province’s commitment to ensuring Indigenous partners share in the economic growth and prosperity generated by energy development in their territories as Ontario expands its electricity system. With a clear path forward, Energy for Generations is not only meeting the demands of today, but it is protecting jobs, supporting workers and powering economic growth for generations to come, while supporting economic reconciliation for generations to come.

Quick Facts

• Energy storage will allow the storage of baseload generation like nuclear and hydro while also supporting the integration of intermittent resources like wind and solar.
• Through the Expedited Long-Term Request for Proposals (E-LT1 RFP) and LT1 RFP procurements, Ontario has secured almost 3,000 MW of battery storage capacity, the largest single battery storage procurement in Canadian history.
• Nine out of 10 of the selected storage projects under the LT1 RFP have Indigenous ownership, representing more than 1,400 MW of capacity.
• The Ontario government has also launched the Second Long-Term Request for Proposals (LT2 RFP), the largest competitive energy procurement in the province’s history.
• The government’s series of competitive procurements are designed to attract a diverse mix of technologies through open, transparent processes that will secure the electricity Ontario needs to support the building of new homes, businesses and communities.
