HOUSTON, Aug 31 (Reuters) - One of Ontario Power Generation’s 490-megawatt units at the Nanticoke coal-fired power station in Ontario was shut by early Monday while another unit returned to service, the Independent Electricity System Operator said in a report.
Unit 7, shut since Aug 10, returned to service while unit 2 shut, according to the report.
The 3,920-MW Nanticoke station, which entered service between 1972 and 1978, is located on the north shore of Lake Erie in Nanticoke about 80 miles (130 km) southwest of Toronto. There are eight 490-MW units at the station.
Other units were available for service.
One MW powers about 1,000 homes in Ontario.
The Ontario government wants to shut all of the coal-fired generation in the province by the end of 2014 for health and environmental reasons.
OPG owns about 6,400 MW of coal-fired generation at four stations: Thunder Bay, Atikokan, Nanticoke and Lambton. The company is considering converting some coal plants to biomass plants starting with Atikokan in the northern part of the province and then Nanticoke.
OPG owns and operates about 22,000 MW of generating capacity and markets power to utilities in Ontario and neighboring U.S. and Canadian electricity markets. (Reporting by Eileen O’Grady; Editing by John Picinich)
