Power generation - it's what we do

Accent: 3fcm9k4uto8x

Life powered by clean, reliable energy

Electricity is the lifeblood of the modern world, pulsing unseen across vast distances to meet our every need at home and in business. In the years ahead, as Ontario and the world decarbonize to meet our climate change goals, the role of electricity in our lives will only grow in importance, powering everything from our daily commute to the heating of our homes.

Several of Ontario Power Generation's (OPG's) generating stations have been powering Ontario for more than a century. We are primed and ready to continue to play this essential role for our province in the century ahead.

To keep Ontario running, OPG operates 75 generating stations, including 66 hydroelectric stations, two nuclear plants, and more.

Our role in the system

OPG is Ontario's largest electricity generator responsible for supplying clean, reliable, safe, and low-cost power to electricity transmission and distribution companies.
