Ontario Breaks Ground on Canada’s Largest Battery Storage Facility, Skyview 2

Ontario breaks ground on Skyview 2, the province’s largest battery storage project supporting clean, reliable energy for a growing economy.

EDWARDSBURGH CARDINAL — Ontario has officially broken ground on Skyview 2, a landmark clean-energy infrastructure project set to become the largest battery storage facility ever procured in Canadian history. The project, located in Edwardsburgh Cardinal, represents a key pillar in the province’s long-term strategy to deliver reliable, affordable and clean energy while supporting major economic growth.

According to the province, Skyview 2 will provide enough stored electricity to power nearly 400,000 homes, strengthening Ontario’s grid as electricity demand is projected to rise significantly by 2050.

A Major Step in Ontario’s Clean Energy Expansion

Premier Doug Ford called the project a “game-changer” for the region’s economy, highlighting its role in supporting energy reliability and future investment:
The new facility will support Ontario’s goal of becoming an “energy superpower”, with meaningful gains for both local communities and Indigenous partners. Construction is expected to create up to 300 jobs, with additional operational roles once the facility opens in 2027.

How Skyview 2 Will Work

Skyview 2 will operate as a lithium-ion battery energy storage system, storing electricity from Ontario’s clean grid during periods of low demand and sending it back when demand increases. This helps stabilize the grid, reduce strain during peak hours, and integrate more renewable and intermittent energy sources such as solar and wind.

The project is being developed through the Independent Electricity System Operator’s Long-Term 1 Request for Proposals (LT1 RFP) and is a partnership between Potentia Renewables Inc. and the Algonquins of Pikwakanagan First Nation.

Indigenous Partnership at the Centre

Chief Greg Sarazin emphasized that the project demonstrates what is possible when First Nations are included as full economic participants in Canada’s energy sector. Skyview 2 is one of several major storage projects in Ontario that incorporate Indigenous ownership.

Part of a Larger Energy Plan

Skyview 2 builds on Ontario’s broader effort to expand its energy storage capacity to nearly 3,000 megawatts (MW)—the largest battery storage procurement in the country’s history.

These investments fall under Energy for Generations, Ontario’s long-term energy roadmap focused on:

• Ensuring a reliable and affordable energy supply

• Supporting economic growth

• Powering new housing and industrial development

• Increasing Indigenous participation

• Preparing for future electrification needs

With the Second Long-Term Request for Proposals (LT2 RFP) now underway, the province is continuing to secure the electricity needed to support its rapidly growing population and economy.
