Hydroelectric development

Modernizing our hydro assets

Ontario Power Generation's (OPG's) 66 hydroelectric power plants on 24 river systems are controlled by 239 dams. One of the benefits of hydropower is that it is a long-lasting, renewable resource. Many of our hydroelectric stations have been operating for the better part of a century.

To continue to generate renewable, low-carbon, and low-cost power at these sites, OPG is investing in upgrading and optimizing its existing hydroelectric assets to meet emerging demand as the province continues to electrify. Redevelopment and optimization opportunities include station refurbishments to modernize facility infrastructure, improve existing generating capacity, uncover additional efficiencies, and, in some cases, redevelop an entire site.

Keeping power affordable

Optimizing our hydroelectric sites takes advantage of existing water management practices and infrastructure to deliver environmental and cost benefits.

New hydro development opportunities

In consultation with Indigenous communities, OPG is exploring building new hydroelectric stations in Ontario’s north.

Preparing to power tomorrow

Before plans take shape and shovels hit the ground, many of our projects begin with Environmental Assessments (EA) or other regulatory processes. Check out additional renewable projects with dedicated websites supporting these specialized processes.
