The Lambton Generating Station is a coal-fuelled power plant located on the St. Clair River near Corunna, Ontario, delivering up to 950 MW of power to the grid.[2] It is owned by Ontario Power Generation.[3]

The plant previously had a total generating capacity of 1,976 megawatts (2,650,000 hp),[4] prior to the permanent shutdown of generating units 1 and 2 (of four) in October 2010.[3][5] The remaining units will be shut down by the end of 2013,[6] with an option of being converted to natural gas or biomass in the long term.[3] It is connected to the power grid via numerous 230 kV lines, and also has two interconnections with Detroit Edison and ITC Transmission via a 230 kV line (Lambton-St. Clair #1) and a 345 kV line (Lambton-St. Clair #2). It is located almost exactly across the St. Clair River from Detroit Edison's St. Clair Power Plant in East China, Michigan.

The facility has three 168-metre (551 ft) smokestacks,[7] one of which is equipped with flue-gas desulfurization units, commonly called "scrubbers", to remove sulfur oxide. Emissions from scrubbers at the Lambton station could be seen for over 16 km, although with the scrubbers operating properly, these plumes likely have over 90% less SO2 compared with other coal-fired stations without scrubbers.[8]

In 2012, plans were announced to relocate a proposed natural gas-powered generating station, originally intended for construction by Greenfield South Power Corporation near Sherway Gardens in Mississauga, to the Lambton Generating Station site.[10]

Construction in Mississauga had already begun in 2011; the original site selection was cancelled during the October 2011 provincial election with the project becoming a key issue during that campaign[11] and the subsequent 2014 campaign.
