About the project
A world-class pumped storage project
This project’s 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.
Ontario is committed to decarbonizing the electricity system. Zero-emissions sources of power (nuclear, hydro, solar and wind) generate excess electricity when it’s not needed. Ontario Pumped Storage will serve and optimize Ontario's electricity system in multiple ways:
- It will store and redeploy power to balance supply with demand
 - It provides on-demand, grid-scale power to replace natural-gas-fired generation
 - It is a proven, safe and reliable technology
