Powering the electric future

As one of North America’s largest, most diverse electricity generators, Ontario Power Generation (OPG) invests in local economies and employs thousands of people across Ontario and the United States. Together with our family of companies, we are leading the development of new clean technologies, advancing electrification initiatives, and refurbishing our existing assets – all to power the demands of a growing clean economy for decades to come.

We delivered one of the world's single-largest climate change actions by closing our coal stations, but that does not make us complacent. It makes OPG hungry to do even more to power Ontario’s homes and businesses – and build on our province’s reputation as a clean-energy powerhouse.

The future of nuclear

OPG is building North America's first small modular reactor (SMR) at our Darlington site. A total fleet of four SMRs will provide 1,200 new megawatts of clean, reliable, safe nuclear power. That's enough to power about 1.2 million homes for decades.

OPG will be the first power generator in North America to build a small modular reactor (SMR).
