The Nanticoke Generating Station is the largest coal-fired power plant in North America, delivering up to 2,760 MW of power into the southern Ontario power grid from its base in Nanticoke, Ontario, Canada. Previous to unit shutdowns, its generating capacity was 3,964 MW. It is owned by Ontario Power Generation, a crown corporation of the Government of Ontario. It was scheduled for decommission in early 2009 as part of the Ontario commitment to eliminate coal power, but this has been repeatedly delayed. The plant has shut down four of its eight units, and is currently scheduled to phase out its use of coal by 2014, switching to biomass or natural gas. Nanticoke is one of Canada`s top ten single sources of greenhouse gases.
