About

At Ontario Power Generation (OPG), our power is changing the world as we strive to electrify life in one generation. As the province’s largest clean power generator, OPG operates one of North America’s most diverse generating fleets. We are now advancing several clean energy innovations, including Small Modular Reactors, low-carbon hydrogen, and energy storage, to help set Ontario and the world on the path to an electrified future, where more aspects of life – from cars to homes and industries – are powered by clean electricity. As part of this vision, we’re also focused on becoming a net-zero company by 2040 and enabling a net-zero economy by 2050. We have already made major strides to a sustainable future. In 2014, OPG burned its last piece of coal to make electricity, which represented one of the world’s single-largest climate change-specific actions. Today, through the dedication of more than 9,500 employees, OPG generates almost half of the electricity that Ontario’s homes, schools, hospitals, and businesses rely on each day. We are committed to ensuring our energy production is reliable, safe, and environmentally sustainable for Ontarians today and for the future. In Ontario, our diverse fleet includes two nuclear stations, 66 hydroelectric stations, two thermal generating stations, one solar facility, and four combined-cycle gas generating stations, which are operated by our subsidiary, Atura Power. Additionally, we own two other nuclear generating stations in Ontario, which are leased on a long-term basis to Bruce Power L.P. In the United States, OPG owns and operates 85 hydroelectric stations in 18 states through our subsidiary, Eagle Creek Renewable Energy. Some of the actions OPG is taking now to prepare for our electric future include the ongoing refurbishment and upgrades of our hydro fleet, refurbishment of our Darlington Nuclear Generating Station, which will secure 30 more years of clean, reliable, low-cost power.
