NEW YORK - Constellation Energy Group Inc's 498-megawatt Ginna nuclear power station in New York shut by early Monday from full power early Friday, the U.S. Nuclear Regulatory Commission said in a report.
Electricity traders said Constellation likely shut the unit for a refueling outage expected to start this past weekend.
The Ginna station, which entered service in 1970, is located in Ontario in Wayne County, about 20 miles east of Rochester, New York. The NRC renewed the plant's original 40-year operating license in 2004 for another 20 years until 2029.
One MW powers about 800 homes in New York.
Constellation, headquartered in Baltimore, Maryland, owns and operates about 9,000 MW of generating capacity, markets energy commodities in North America, and transmits and distributes electricity to 1.2 million customers and natural gas to 630,000 customers in Maryland.
