Currently (2013 Sep. 28th) all of them are suspended. Fukushima (1) Nuclear Power Plant (1,884,000 kW) was shut down permanently because of the earthquake in 2011. We are living without electricity from nuclear power plants.
It is planned that Ooi power plant and Kashiwazaki-Kariwa nuclear power plant are going to be activated again in the future.
As you may notice there are a lot of power plants in Fukui. Fukui is a kind of hometown of nuclear power plants.
In Japan, there are 10 main electricity companies. Service areas of them are not overlapped. It means there is just one electricity company for each city/town. We can not choose an electricity company. The following is the list of electricity companies and their territories. 2016 updated; we can buy electricity from some agencies, in stead of the source company.
|北海道電力||Hokkaido Electric Power Co., Inc.||Hokkaido|
|東北電力||Tohoku Electric Power Co., Inc.||Tohoku district & Niigata|
|東京電力||TEPCO (Tokyo Electric Power Company, Inc.)||Kanto district & Yamanashi, part of Shizuoka|
|北陸電力||Hokuriku Electric Power Co.||Ishikawa, Toyama, part of "Fukui, Gifu"|
|中部電力||Chubu Electric Power||Aichi, Nagano, most of "Gifu, Mie, Shizuoka"|
|関西電力||Kansai Electric Power Co., Inc.||Kinki district, part of "Fukui, Gifu, Mie"|
|中国電力||Chugoku Electric Power Co., Inc.||Chugoku district|
|四国電力||Shikoku Electric Power Co., Inc.||Shikoku district|
|九州電力||Kyushu Electric Power Co., Inc.||Kyushu district. exclude Okinawa|
|沖縄電力||Okinawa Electric Power||Okinawa|
Fukushima (1) Nuclear Power Plant which belongs to TEPCO is located in the territory of Tohoku Electric Power Co. TEPCO has another plant, Kashiwazaki-Kariwa nuclear power plant. Kashiwazaki-Kariwa is located in the Tohoku Electric Power's area. So it is a strange thing that TEPCO does not have their own plant in their own area.
