Successful shutdown of Jinping I Hydropower Station, another giant hydropower station in China

At 10:06 on the 4th, it was located in Muli Tibetan Autonomous County and Yanyuan County of Liangshan Yi Autonomous Prefecture in Sichuan Province. Another giant hydropower station on the Yalong River, Jinping I Hydropower Station, successfully intercepted.

At 9 o'clock, the Yalong River hydrological situation shows that the current flow rate is 470 cubic meters per second, the width of the cofferdam is about 10 meters, and the difference between the upper and lower reaches of the cofferdam is 5 meters, which is very beneficial to the interception. At 9:35, the main venue of Chengdu issued a interception and closing command through satellite remote transmission. At 10:06, the upstream Longkou victory achieved Helong.

The Jinping I Hydropower Station with a total investment of about 24 billion yuan is located in the Muli Tibetan Autonomous County and Yanyuan County of Liangshan Yi Autonomous Prefecture, Sichuan Province. It is the leading cascade hydropower station in the downstream of the Yalong River, with a total installed capacity of 3.6 million kilowatts and an average annual power generation of 166.2. Billion kWh. The Yalong River is extremely rich in hydropower resources. The basin's dry tributary technology can develop a capacity of 34.62 million kilowatts, ranking first among all rivers in Sichuan. Among them, the two rivers below Jiangkou is one of the twelve major hydropower bases in China's energy development plan, and it is an important power supply base for the planned “West-East Power Transmission”.

As the leading power station of the five cascade hydropower stations planned for the Kara-Jiangkou section of the mainstream of the Yalong River, the Jinping I-level power station has many world firsts, including the world's first high arch dam of 305 meters and the world's largest water. Work tunnels, etc. Its development task is mainly power generation. It has a total storage capacity of more than 15 billion cubic meters in cooperation with Ertan Hydropower Station. The compensation benefit can also be extended to the lower reaches of the Jinsha River and the Gezhouba and Three Gorges power stations of the Yangtze River. At the same time, it has important functions of sand interception and flood storage. Flood control burden in the middle and lower reaches of the Yangtze River.

According to Chen Yunhua, general manager of Ertan Hydropower Development Co., Ltd., the successful interception of the Yalong River was two years ahead of the state-approved interception period, creating a new record in the history of hydropower development in China. At the same time, the realization of this major milestone of interception marks that the main project of Jinping I Hydropower Station has already started the basic conditions at the end of 2006, and laid a solid foundation for the smooth start of Jinping II Hydropower Station.
