Ontario registered a large drop in emissions in 2008, due to lower demand, natural gas prices and government instructions to Ontario Power Generation regarding a gradual decommissioning of coal-fired generation by 2014. According to the Independent Electricity System Operator of Ontario, 4,700 MW of new natural gas-fired generation and 1,100 MW of wind farms have been commissioned in the province between 2003 and 2009. The new natural gas capacity will allow Ontario to retire 2 units each at the Nanticoke and Lambton generating stations by the end of 2010, on track for a complete phase-out by the end of 2014.
