Chongqing Power Generation Co., Ltd., a state-owned industrial enterprise, is affiliated with the Chongqing Municipal Bureau of Electric Power under the Ministry of Electric Power. Currently, the company operates a first-phase power plant consisting of two 50,000-kilowatt high-temperature and high-pressure generating units. The plant employs 688 workers, has fixed assets worth 253.92 million yuan, and has achieved an average annual power generation of over 650 million kilowatt-hours over the past three years. The second-phase project of the power plant is located within Kaizhou County, in the core area of the Three Gorges Reservoir, and is classified as a pit-mouth power plant. The current phase of construction involves two 300,000-kilowatt generating units; initially, one domestically produced 300,000-kilowatt coal-fired unit will be built, with certain common facilities being constructed ahead of schedule. This project will replace small coal-fired generating units totaling 2.735 million kilowatts currently operating on the Chongqing power grid. The construction of this project is being carried out at the northwest expansion end of the first-phase plant. The plant requires approximately 800,000 tons of coal annually, sourced from local mines in Kaizhou County and neighboring Yunyang and Xuanhan Counties. Water for the plant is drawn from the Dongli River, and the water supply can fully meet the plant’s needs. The ash disposal site selected is the Majiagou Ash Yard, located about 2.1 kilometers from the power plant. The project uses low-sulfur coal, and the Environmental Protection Bureau has already approved the environmental impact assessment report. The project will connect to the power system at a primary voltage level of 220 kilovolts. The power plant is a key national power construction project. Each year, the plant has exceeded its production targets set by higher authorities, with cumulative power generation reaching over 5 billion kilowatt-hours and creating social economic value exceeding 30 billion yuan.
