The station has been converted to use advanced biomass as fuel to generate electricity.
Ontario Energy Minister Bob Chiarelli said: "Ontario is a leader in building a clean energy system, and the completion of the conversion to use advanced biomass at Thunder Bay is key to building a cleaner future for the people of our province."
Thunder Bay-Superior North member of provincial parliament (MPP) Michael Gravelle said: "Converting to advanced biomass is a positive step forward for the Northern Ontario economy.
"It keeps jobs at the Thunder Bay Generating Station and shows that our community and the Province of Ontario are world leaders in generating sustainable energy."
Thunder Bay MPP Bill Mauro said: "These conversions are critical to Northwestern Ontario’s energy security and provide an important tax base for their local communities. The investments have also created new opportunities for the forestry industry while protecting local well-paying jobs."
Additionally, OPG is supporting biomass research with support from OPG Bioenergy Learning Research Centre at Confederation College in Thunder Bay.
