The Ontario government has announced the launch of pre-development work for the Ontario Pumped Storage Project, a collaboration between TC Energy and the Saugeen Ojibway Nation. If approved, the project would become Canada’s largest pumped storage facility, with the capacity to store up to 1,000 megawatts of clean electricity — enough to power one million homes for 11 hours.
The facility, to be located in Meaford, will operate by pumping water from Georgian Bay into a reservoir during periods of low electricity demand, then releasing it to generate power during peak demand. The project is described as a natural battery, using water and gravity to provide clean energy when needed most.
The province has committed up to $285 million for pre-development activities, including detailed cost estimates and environmental assessments. A final decision on the project will follow the completion of these assessments to ensure it aligns with the interests of Ontario ratepayers.
The pumped storage facility is part of Ontario’s broader strategy to meet growing energy demands. It will complement other initiatives, such as the proposed Bruce C nuclear station, which would generate clean, zero-emissions power to support the province’s energy needs.
Design plans for the facility have been adjusted to address community concerns regarding environmental protection, economic impact, and local lifestyles.
Key features include:
- Buried powerhouse: An underground powerhouse will minimize visible structures and noise, reducing the project’s visual impact, particularly from Georgian Bay.
- Water intake/outfall: Intake and outfall structures will be located deep below the lakebed, protecting near-shore aquatic ecosystems and avoiding shoreline disturbance.
- Fish protection: Measures such as reduced water withdrawal speeds and permanent fixed screens will safeguard fish and their habitats.
TC Energy emphasized environmental stewardship, noting that extensive studies will assess the project’s impact on fish, wildlife, and water resources. The findings will guide federal and provincial approval processes under the Impact Assessment Act and the Environmental Assessment Act.
“We are committed to protecting the environment while advancing clean energy solutions,” TC Energy said in a statement. “These studies will ensure the project aligns with our principles of stewardship, protection, and performance.”
The Ontario Pumped Storage Project is positioned as a critical step in ensuring the province’s energy security and affordability while meeting environmental commitments.
