Energy and Society Thermal Energy: Ontario Power Generation operates five Thermal electricity-generating stations with a combined capacity of 5,447 megawatts. Four of these stations are currently fuelled by coal. The fifth, Lennox Generating Station, is dual-fuelled by oil and natural gas. Thermal stations are an important part of Ontario Power Generation’s fleet, as they are able to start and stop quickly, when needed, to meet peaks in demand and to satisfy electricity needs that cannot be met by Ontario’s nuclear, hydroelectric and growing portfolio of wind and solar energy systems. Ontario Power Generation is making the transition to a lower carbon future and will phase out the use of coal to produce electricity by the end of 2014. Two coal-fuelled generating units at Lambton Generating Station and four at Nanticoke Generating Station have been retired. Nuclear Energy: Nuclear power meets more than 50 per cent of Ontario's electricity needs. It has two major benefits - low operating costs and virtually none of the emissions that lead to smog, acid rain or global warming. These benefits make nuclear a very attractive option for meeting the province's electricity needs well into the future. Ontario Power Generation owns and operates the Pickering and Darlington Nuclear Power Stations. The two stations have a combined generating capacity of about 6,600 megawatts. Accounting for almost 30 per cent of the electricity generated in Ontario in 2011, Ontario Power Generation’s 10 nuclear units generated 48.6 terawatt hours. Ontario Power Generation's nuclear production benefited from the outstanding performance of the Darlington generating station. The station achieved a capability factor of 95.2 per cent. Five of Ontario Power Generation’s ten units operated at a capability factor of greater than 90 per cent, and two other units operated at a capability
