The Thunder Bay Generating Station is located in the City of Thunder Bay, next to the Lakehead Region Conservation Authority's Mission Island Marsh. First placed in service in 1963, it is the oldest of OPG's thermal electricity-generating stations.
OPG stopped using coal as fuel in April 2014, and one of the station’s two units has been converted to use advanced biomass and is available to operate on this dispatchable, renewable fuel.
Using advanced biomass to generate renewable electricity is an exciting new area of development for the electricity industry and OPG is pleased to be at the forefront of this technology.
Advanced biomass has emerged as a leading candidate for coal plant fuel conversions due to its favourable handling and storage properties. It is a solid biomass fuel, processed with advanced techniques. It has higher energy density and is hydrophobic (repels water) allowing it withstand the elements while being stored outside.
A public information drop-in was held Oct. 30, 2014 where OPG staff shared information about the project with the community. OPG announced the completion of the conversion project in a February 2015 news release.
The role of OPG’s Thunder Bay station is to provide reliability during peak demand times and back up electricity generation when other sources are not available. This role will continue on advanced biomass.
