Established in 195 1, TEPCO is a large-scale power enterprise integrating power generation, transmission and distribution in Japan. Its power grid mainly covers Tokyo and its surrounding eight counties, and bears the power supply share of Japan's near 1/6. It is the highest-paid power company in Japan and the largest private nuclear power producer in the world.
Tokyo Electric Power Company, TEPCO for short, is the largest private power enterprise in Asia and even in the world. Tokyo Electric Power Company is one of the nine largest electric power companies in Japan and one of the most famous electric power companies in the world. The company operates three nuclear power plants *** 17 reactors, which are located at Fukushima Daiichi Nuclear Power Plant, Fukushima II Nuclear Power Plant and Kashiwazaki Yuki Nuclear Power Plant in the middle of Niigata Prefecture.
Development history
Tokyo Electric Power was established in 195 1, and its predecessor "Tokyo Electric Light" was established in 1883. In just 60 years, TEPCO has built 190 power plants. In 1970s, Tokyo Electric Power Company began to build diversified and clean installation structures. The installed capacity of Tokyo Electric Power Company is mainly natural gas and nuclear power, accounting for more than 70% of the total installed capacity.
Tokyo Electric Power Company has always attached great importance to the development of large-capacity and high-efficiency units. At the end of 1997, large thermal power units of 600MW and above (excluding gas-steam combined cycle units) accounted for 55% of the total thermal power capacity (including combined cycle units). In the development of gas-steam combined cycle, people pursue high efficiency, so the capacity and gas temperature of the unit have improved.
Units that have been put into operation, single unit capacity 1440MW, gas temperature 1300℃, and thermal efficiency of 49% (calculated by higher calorific value). Around 2002, a gas-steam combined cycle unit with a single unit capacity of 2000MW, gas temperature 1450℃ and thermal efficiency of 53% was put into operation.
In the choice of fuel for power generation, choose fuel with low sulfur content, especially actively replace oil with natural gas (liquefied natural gas LNG and liquefied petroleum gas LPG) and atomic energy.
