About the project


A world-class pumped storage project

This project is one of the largest climate-change initiatives being developed in Canada. Its state-of-the-art design incorporates 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 benefiting 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.
