What leadership looks like

Ontario Power Generation (OPG) did not become one of North America's top power producers by standing still. We are always looking to the future to ensure we are continuing to innovate and invest in reliable, clean electricity generation and related electrification services, such as energy storage and charging infrastructure. From nuclear refurbishment to hydrogen to a world-leading fleet of small modular reactors, OPG is boldly defining what a low-carbon future can look like.

Darlington New Nuclear project

Being first matters. OPG will be the first power producer in North America to build a commercial small modular reactor and will begin planning and licensing for three more, securing a new source of clean power that will help us reach net-zero emissions.

Darlington Refurbishment project

OPG's world-class Darlington Refurbishment project is helping create 14,200 jobs per year, while contributing $89 billion to the economy, and ensuring clean power for decades to come.

New hydro opportunities

In consultation with Indigenous communities, OPG is actively exploring new hydroelectric development opportunities in Ontario's North.
