Tepco Idles Unit Cutting Japan Nuclear Capacity to 8.1%

Japan has four nuclear reactors operating today with capacity of 3,958 megawatts, or 8.1 percent of the total, after a unit was idled yesterday, according to data compiled by Bloomberg News.

Tokyo Electric Power Co. shut the 1,100-megawatt No. 5 reactor at its Kashiwazaki Kariwa plant in northern Japan yesterday for regular maintenance, spokesman Masato Yamaguchi said by phone today. The utility known as Tepco plans to halt the last operating reactor at the world’s biggest nuclear station by the end of March, he said.

The following table shows the status of the 54 reactors with capacity of 48,960 megawatts operated by Japanese power companies. Capacity figures are in megawatts.
