Thunder Bay Generating Station

The Thunder Bay Generating Station (GS) is located in the City of Thunder Bay, next to the Lakehead Region Conservation Authority's Mission Island Marsh. It is one of OPG's five thermal electricity generating stations.

Its two operating coal-fuelled generators produce up to 306 megawatts (MW) of electricity, using low-sulphur powder river basin sub-bituminous coal. Thunder Bay's role is to provide reliability during peak demand times and back up electricity generation when other sources are not available.

Ontario's Long-Term Energy Plan calls for the conversion of Thunder Bay GS to natural gas. OPG has substantially completed the definition phase of this project.

On Nov. 1, 2012, OPG announced it is suspending further work on the Thunder Bay GS gas conversion, pending a review by the Ontario Power Authority of electricity needs in northwestern Ontario.
