Tokyo Electric Power Company, commonly known as TEPCO, is one of Japan's largest electric utility companies. Founded in 1951, it provides electricity to the Kanto region, which includes Tokyo and its surrounding areas. TEPCO plays a crucial role in Japan's energy supply, operating numerous power plants and managing the electrical grid. The company gained international attention following the Fukushima Daiichi nuclear disaster in 2011, which was triggered by a massive earthquake and tsunami. This incident led to significant changes in Japan's energy policies and raised concerns about nuclear safety, prompting TEPCO to focus more on renewable energy sources and improving safety measures.
