金川水电站成功下闸蓄水 每年可替代约百万吨燃煤消耗

Core Viewpoint - The completion of the dam construction at the Jinchuan Hydropower Station marks the countdown to its commissioning, highlighting significant advancements in China's hydropower infrastructure and ecological protection efforts [1][3]. Group 1: Project Overview - The Jinchuan Hydropower Station, located in Aba Prefecture, Sichuan Province, is the sixth hydropower station in the Dadu River's 28-level planning scheme, with a total installed capacity of 860 megawatts [1]. - The construction site is characterized by complex geological conditions, being the highest rockfill dam in a deep cover layer region in China, presenting unprecedented construction challenges [1]. Group 2: Environmental and Technological Innovations - The project features Asia's longest ecological fishway, designed to protect migratory fish species in the Dadu River through a combination of natural river channels and tunnels [3]. - The Jinchuan Hydropower Station has established China's first fully domestic three-dimensional digital modeling standard system for hydropower projects, enhancing geological analysis, construction simulation, and safety management [3]. Group 3: Economic and Environmental Impact - Once operational, the Jinchuan Hydropower Station is expected to generate an average annual electricity output of approximately 3.5 billion kilowatt-hours, replacing about one million tons of coal consumption and reducing carbon dioxide emissions by around one million tons [3]. - The project is significant for optimizing China's energy structure and promoting coordinated economic and social development [3].
