Ministry of Water Resources: In 2020, the annual power generation of the Three Gorges Project will set a new record for the annual power generation of a single hydropower station in the world.
According to the website of the Ministry of Water Resources, in 2020, the Ministry of Water Resources organized relevant technical units to carry out comprehensive monitoring of the operation safety of the Three Gorges Project, dynamically grasping the operation and benefits of the Three Gorges Project, hydrology and water resources, soil and water conservation in the reservoir area, the safety of the reservoir area, the middle and lower reaches of the Yangtze River and other related conditions, and comprehensively compiled the main monitoring results of the year to form the Three Gorges Project Bulletin 2020, which was published on the portal of the Ministry of Water Resources.
According to the communique, the Three Gorges Project will operate well in 2020, and the comprehensive benefits such as flood control, power generation, shipping, water resources utilization and ecological environment protection will be brought into play significantly. In 2020, the Yangtze River experienced the worst basin flood since 1998, and the Three Gorges Reservoir experienced the largest inflow peak flow, reaching 75,000 cubic meters per second. Through scientific dispatching, the Three Gorges Project has effectively dealt with five numbered floods with peak flow exceeding 50,000 cubic meters per second, and accumulated 25.4 billion cubic meters of flood storage, thus avoiding the use of Jingjiang flood diversion area and Chenglingji flood storage and detention area. The experimental water storage target of 175 meters was successfully achieved for the 11th consecutive year after flood season. In 2020, the annual power generation will be 111.8 billion kWh, setting a new record for the annual power generation of a single hydropower station in the world. The annual cumulative cargo volume of the Three Gorges Shiplock reached 137 million tons. The Three Gorges Reservoir has replenished water for 164 days in the middle and lower reaches of the Yangtze River. For the 10th year in a row, the 14th ecological regulation experiment of Three Gorges Reservoir was carried out to promote the reproduction of the four major fishes (black carp, grass carp, silver carp, bighead carp) and other fishes producing drifting eggs, and the effect was good. The Three Gorges Reservoir has more water and sediment than in 2019, and the surface water resources in the reservoir area are more than in previous years. The area of soil erosion in the Three Gorges reservoir area has decreased and new achievements have been made in soil and water conservation. The frequency and intensity of earthquakes in the Three Gorges reservoir area are low, the banks of the Three Gorges reservoir are generally stable, the influence of water storage and retreat is properly handled, the river regime in the middle and lower reaches of the Yangtze River is generally stable, and comprehensive control measures are further strengthened.
