Atikokan Generating Station is a biomass power plant owned by Ontario Power Generation (OPG) located 8 km (5 mi) north of Atikokan, Ontario (190 km (118 mi) west of Thunder Bay).

Until 2012, it had one coal-fueled generating unit with low nitrogen oxide (NOx) burners, providing a peak output of 230 MW fuelled by low-sulfur lignite coal from the Ravenscrag Formation in Southern Saskatchewan.

[1] In late 2012, the facility powered down and underwent renovations, due to the Ontario government's initiative to eliminate all coal-fired electricity generation.

[2] It is the first generating station to be converted by OPG to be fueled by biomass,[3] and is North America's largest purely biomass-fueled power plant.

This plant is connected to the provincial power grid via several 230,000-volt transmission lines.
