四川雅砻江流域两座大型水电工程实现同步大江截流

Core Insights - The simultaneous river diversion of two large hydropower stations, Mengdigou and Yagen I, marks a significant milestone in the Yalong River basin hydropower development [1][3] Group 1: Project Details - Mengdigou Hydropower Station has a total installed capacity of 2.4 million kilowatts and an average annual power generation of approximately 10.4 billion kilowatt-hours [3] - Yagen I Hydropower Station has an installed capacity of 300,000 kilowatts and an average annual power generation of about 1.15 billion kilowatt-hours [3] - Both hydropower stations are part of the "one reservoir and seven levels" development plan in the Yalong River basin, with Mengdigou being the largest ongoing hydropower project in the region [3] Group 2: Operational Efficiency - The simultaneous river diversion is a first for the Yalong River basin, enhancing overall efficiency and minimizing the impact of diversion on other downstream hydropower stations [3][5] - The operation utilizes the regulation capacity of the upstream Two Rivers Mouth Reservoir to create a favorable "low flow window" for construction, significantly reducing construction difficulty and increasing safety [5] Group 3: Future Development Plans - The Yalong River basin hydropower development company is part of a national plan for a water-wind-solar integrated demonstration base, with a total planned installed capacity of 78 million kilowatts by 2035 [5] - Currently, the base has approximately 21 million kilowatts of clean energy installed and around 14 million kilowatts under construction, contributing over 1.1 trillion kilowatt-hours of clean electricity [5]
