Ontario Pumped Storage Project

 

Balancing our electricity supply

One of Canada's largest climate-change initiatives

Our project is one of the largest climate-change initiatives being developed in Canada. It is a truly state-of-the-art design, incorporating the latest and best technologies to fully enhance a reliable and proven energy storage technology that accounts for 95 per cent of global energy storage.

The project's zero emission footprint makes it an environmentally responsible energy solution for Ontario that will also help Canada meet its 2030 target of a 30 per cent reduction in greenhouse gas emissions and net-zero carbon emissions by 2050.

Aside from benefitting the climate, the project will ensure Ontario gets the most value from its power generation, storing excess energy at night, during periods of low demand, and providing an energy balance by delivering that stored energy during the day, at times of extreme weather, during periods of high demand, reliably and responsibly.

Media Advisory:

TC Energy reaches agreement with National Defence to develop proposed world-class pumped storage project

TC Energy will develop a transformative 1,000-megawatt clean energy storage project, subject to conditions and regulatory approval. The Ontario Pumped Storage Project, proposed to be constructed on Department of National Defence’s 4th Canadian Division Training Centre property, will be Ontario’s largest energy storage project, optimizing the province’s electricity system and delivering more than $250 million in annual savings to electricity consumers.

Read the full Media Advisory.

TC Energy is proposing to develop an energy storage facility that would provide 1,000 megawatts of flexible, clean energy to Ontario’s electricity system using a process known as pumped storage.

The project's zero emission footprint makes it an environmentally responsible energy solution for Ontario that will also help Canada reduce greenhouse gas emissions.

Aside from benefitting the climate, the project will ensure Ontario gets the most value from its power generation, storing excess energy at night, during periods of low demand, and providing an energy balance by delivering that stored energy during the day, at times of extreme weather, during periods of high demand, reliably and responsibly.  The project will reduce the need for reliance on natural-gas-fired power generation, will save Ontario ratepayers $250 million per year, and create 1,000 jobs during development and construction.

At 1,000 MW, the project will be Ontario’s biggest battery, storing enough clean carbon-free electricity to power nearly a million homes.

Pumped hydro storage (pumped storage) involves pumping water from a low-lying reservoir during periods of low demand for electricity, typically at night, to a higher-elevation reservoir. When electricity demand is greater (and therefore electricity is more expensive), operators release water back to the lower reservoir through turbines that generate electricity (similar to hydropower from dams).

TC Energy is in the development phase of this project. There are numerous levels of assessment and approvals required before this concept could become a reality. If developed, the proposed facility would be co-located on the existing Canadian Army’s 4th Canadian Division Training Centre, north of Meaford, Ont. It would be designed to store emission-free energy and would provide that energy to Ontarians when they need it most.
