Tokyo Electric Power Company (Tepco)

Tokyo Electric Power Company (Tepco) is a Japanese electric utility, notable as the operator of the Kashiwazaki-Kariwa Nuclear Power Plant, the world's largest. Tepco is currently newsworthy due to the attempted restart of reactor number six at the Kashiwazaki-Kariwa plant, its first nuclear reactor brought back online since the 2011 Fukushima disaster. The plant, located in Niigata Prefecture, had been closed since Fukushima. Operations to restart reactor six began on Wednesday but were suspended just hours later due to an alarm during start-up procedures. While the reactor remained stable, the company has not indicated when operations will resume. This restart and subsequent suspension are significant due to the close scrutiny Tepco faces regarding safety measures and its efforts to recover from the Fukushima accident.
