A New Era of Cleaner Air in Ontario

Atikokan Generating Station Operational with Biomass Fuel

Ontario is now home to North America's largest power plant fuelled completely by biomass.  The Atikokan Generating Station conversion is complete and the station is now generating electricity and helping meet local power needs in northwestern Ontario.

Atikokan Generating Station, which employs 70 full-time workers, burned its last coal, two years ago, on Sept. 11, 2012. Conversion of the station began in mid-2012 and included construction of two silos and boiler modifications to accommodate the biomass. The project employed over 200 highly skilled trades people and technical workers.

A coal-free energy mix will lead to a significant reduction in harmful emissions, cleaner air and a healthier environment.

The biomass used to fuel Atikokan Generating Station is being harvested and processed in Ontario.  Domestic suppliers have leveraged this opportunity to secure contracts to provide pellets to international buyers.

Providing clean, reliable and affordable power is part of the government's plan to invest in people, build modern infrastructure and support a dynamic and innovative business climate across Ontario.  

Quick Facts

  • Biomass is a sustainable fuel recognized across the world as a contributor to greenhouse gas reductions.
  • Atikokan Generating Station will provide renewable peaking power, and can be turned on when electricity demands are highest.
  • OPG has contracts in place with two companies in northwestern Ontario to supply the wood pellets. Rentech Inc. and Resolute Forest Products Canada will each supply 45,000 tonnes of wood pellets annually.
  • The closure of Ontario’s coal plants comes as the province moves toward implementing a smarter electricity grid, increasing efficiencies within the electricity system, introducing strong conservation efforts and committing to cleaner energy sources.
  • Replacing coal-fired electricity generation was the single largest climate change initiative undertaken in North America and was the equivalent of taking up to 7 million cars off the road.

“A new era has dawned in Ontario; one where the air will be cleaner and the multiple costs of coal-fired generation have become a distant memory. Atikokan’s successful conversion to biomass will put Ontario on the world map as a leader in using this sustainable fuel source for electricity production.”

Bob Chiarelli

Minister of Energy

“It is gratifying to see the effort expended on this project has come to a very successful conclusion. Atikokan is now home to the largest completely biomass fired energy generation facility in North America. This project will help ensure the energy security of Northwestern Ontario and provide health and employment benefits to those living in Atikokan for decades to come. I want to thank everyone for their support over the years as we worked towards making today a reality.”

Bill Mauro

MPP, Thunder Bay-Atikokan

“Northwestern Ontario is on the leading edge of some very exciting new mining and forestry developments and I am very pleased that our government is taking action to meet the future energy needs of our region. This project is not only providing more clean power to Ontarians, it is creating promising new economic opportunities and sustainable jobs for Northwestern Ontarians.”

Michael Gravelle

MPP, Thunder Bay-Superior North

“Close to 100 per cent of the electricity OPG produces is from sources that are virtually free of climate change or smog causing emissions. Atikokan GS is a unique addition to our clean energy portfolio as it provides dispatchable renewable energy that can be used when the power system needs it.”
