The Nanticoke Generating Station was the largest coal-fired power plant in North America. At full capacity, it could provide 3,964 MW of power into the southern Ontario power grid from its base in Nanticoke, Ontario, Canada. It is owned by Ontario Power Generation. It was decommissioned in 2013 as part of the Government of Ontario's commitment to eliminate coal power. Prior to the commencement of decommissioning, Nanticoke was one of Canada's top ten single sources of greenhouse gases.
