Tokyo Electric Power Company introduction and official website domain name

Tokyo Electric Power Company (TEPCO), established in 1951, is a major Japanese power company integrating power generation, transmission, and distribution. Its grid primarily covers Tokyo and eight surrounding prefectures, supplying nearly one-sixth of Japan's electricity. It is Japan's highest-earning power company and the world's largest private nuclear power company. As of the end of March 2010, the company's total sales reached 5 trillion yen (approximately 400 billion yuan) and employed 52,000 people.

During the March 11, 2011, earthquake off Japan's main island of Honshu, Tokyo Electric Power Company (TEPCO) faced widespread controversy for its poor handling of the nuclear power plant leak. On March 3, 2014, 58 Fukushima residents who had taken refuge in Miyagi Prefecture following the accident at TEPCO's Fukushima Daiichi nuclear power plant filed a lawsuit in the Sendai District Court in Miyagi Prefecture, demanding compensation from the Japanese government and TEPCO.

On the 2nd, TEPCO estimated internal radiation levels by analyzing video noise and other factors, stating that the maximum radiation level could reach 530 sieverts per hour, far exceeding the previously measured maximum of 73 sieverts per hour. Exposure to such an environment could be fatal within tens of seconds.

On March 17, 2024, local time, Tokyo Electric Power Company (TEPCO) announced the completion of its fourth round of sea discharges of contaminated water from the Fukushima Daiichi Nuclear Power Plant. On March 18, a Japanese court ruled in its second instance that TEPCO should pay approximately 158 million yen in compensation to victims of the Fukushima nuclear accident. Regarding the Japanese government's liability, the Sendai High Court upheld the first-instance ruling, finding that the Japanese government was not responsible. On August 7, TEPCO began its eighth sea discharge of contaminated water from the Fukushima Daiichi Nuclear Power Plant, with a total volume of approximately 7,800 tons.

On April 10, 2025, local time, TEPCO began its 12th sea discharge of contaminated water from the Fukushima Daiichi Nuclear Power Plant, with a total volume of 7,800 tons. On August 7, TEPCO initiated its 14th sea discharge of contaminated water from the Fukushima Daiichi Nuclear Power Plant.

Tokyo Electric Power Company (TEPCO), founded in 1951, is a giant power company integrating power generation, transmission, and distribution. With a total market capitalization exceeding 14 trillion yen (1.1 trillion RMB), it is the largest private power company in Asia and even the world.
