OPG profile

Why choose us

Canadian Nuclear Partners was established in 2012. Its parent company, Ontario Power Generation (OPG) is a publicly-owned, Ontario-based electricity company. One of North America’s largest power producers, OPG's diversified, low-cost and low-emission portfolio includes 66 hydroelectric, two biomass, one thermal and two nuclear stations, and one wind power turbine. OPG also owns two other nuclear power stations which are leased to Bruce Power L.P., and is a co-owner but not an operator of the Portlands Energy Centre and the Brighton Beach gas-fired generating station.

Established in 1999, OPG has built a solid track record of performance excellence, supplying safe and reliable electricity at a low cost. It is also a proven project manager that has delivered a number of complex expansion and rehabilitation initiatives.

OPG uses best practices as the foundation for predictable and efficient project delivery. It focuses on delivering on time and on budget to the highest quality standards while ensuring the safety of all personnel involved.

Nuclear highlights
  • Produces over 18 per cent of Ontario’s electricity from the Darlington Nuclear Generating Station alone, and about 35 per cent between the Darlington and Pickering nuclear generating stations combined;
  • Darlington Nuclear has achieved seven consecutive years of the highest possible safety rating;
  • Darlington’s outstanding performance ranks among the top nuclear stations in the world and is internationally recognized;
  • Currently executing mid-life refurbishment of Darlington Nuclear – Canada's largest clean energy project – a 15-year endeavor that’s increasing Ontario’s nominal GDP by $14.9 billion, and by a total of $89.9 billion when calculating in 30 more years of station operations;
  • Invested more than $200 million in Pickering Nuclear since 2010, which recently achieved its best operating reliability performance in the station’s history;
  • Successfully placed Pickering Units 2 and 3 in a safe shutdown state;
  • Operating Pickering Nuclear to 2024 would avoid eight million tonnes of greenhouse gas emissions and protect 4,500 jobs across Durham Region;
  • Recognized as an industry leader in responding to the Fukushima nuclear disaster, launching over a dozen projects to further strengthen plant and public safety;
  • Executes over $300 million annually in nuclear project work;
  • Strong waste management record – after thousands of shipments and millions of kilometers transported, not a single gram of radioactive material has ever been released to the environment; and
  • Has a managed system that integrates performance measurement, sustainability and external benchmarking, and promotes continuous improvement.

Hydroelectric and thermal highlights
  • Successfully established hydroelectric development partnerships with the Moose Cree First Nation, the Lac Seul First Nation, and the Taykwa Tagamou Nation;
  • Currently expanding the existing Ranney Falls Generating Station by adding a new hydroelectric generating unit and powerhouse, which will increase the station’s capacity by 8-10 megawatts (MW) to approximately 18-20 MW;
  • Completed construction of Peter Sutherland Sr. Generating Station (GS) in March 2017, safely, on budget and ahead of schedule. This new source of clean, reliable, low-cost electricity is an equity partnership with Taykwa Tagamou Nation;
  • Completed the Lower Mattagami Project, which added 438 megawatts (MW) of new hydroelectric capacity with virtually no environmental impact. The project added a new generating unit at each of the existing Little Long, Harmon and Kipling generating stations, and replaced the old Smoky Falls generating station with a new three-unit facility;
  • Successfully converted two coal plants in Northern Ontario to run on biomass fuel:
    • The 205 MW Atikokan plant, which uses Whitewood pellets, is the largest capacity 100 per cent biomass generating station in North America; and
    • The Thunder Bay Genrating Station, which uses advanced biomass pellets, is the first of its kind in the world, establishing a platform for new technologies in the field of environmentally responsible energy supply.
