Building a stronger, more resilient Ontario

At Ontario Power Generation (OPG), innovation is in our DNA. We are never content with the status quo, so we’re hard at work on key projects that will help us keep rates low, reduce carbon emissions, create jobs, and electrify life in Ontario.

At OPG, we're delivering innovative, industry-leading energy projects to ensure that as electricity demand increases, we're able to power the lives of Ontarians for generations to come.

Nuclear projects

From refurbishing the Darlington Nuclear Generating Station to being the first in North America to build a commercial small modular reactor, OPG is busy making sure that nuclear power can continue to supply Ontario with carbon-free energy 24/7/365.

New generation opportunities

The Ontario government has directed OPG to begin engagement on potential new generation at three of its existing sites: Lambton, Nanticoke, and Wesleyville.

Hydroelectric development

OPG’s 66 hydroelectric stations provide a steady supply of emission-free power. To ensure there is enough clean power to electrify more areas of life in Ontario, OPG is modernizing our existing hydro assets while exploring new hydro projects across the province.
