Core Viewpoint - The Yebatang Hydropower Station, the highest hyperbolic arch dam under construction in China, has officially commenced power generation with its first batch of units, contributing to the development of a new energy system and the construction of an energy powerhouse [1][2]. Group 1: Project Overview - The Yebatang Hydropower Station is located at the junction of Baiyu County in Ganzi Tibetan Autonomous Prefecture, Sichuan Province, and Gongjue County in Changdu City, Tibet, on the mainstream of the Jinsha River. It is a major project under China's 14th Five-Year Plan [1]. - The total installed capacity of the Yebatang Hydropower Station is 2.24 million kilowatts, making it the largest hydropower station in the upper reaches of the Jinsha River in the Sichuan-Tibet section [1][2]. - The maximum dam height is 217 meters, characterized by five high features and one large feature: high cold, high altitude, ultra-high arch dam, high ground stress, high burial depth, and large-span underground powerhouse [1][2]. Group 2: Technological Innovations - During construction, the project team conducted research on high-altitude cold region ultra-high arch dam winter concrete construction technology and innovatively established the "Yebatang Cloud" digital management platform, creating a smart control system covering the entire construction process [2][3]. - The project achieved uninterrupted concrete pouring year-round in high-altitude cold regions for the first time in China, providing valuable experience for seamless dam construction in similar environments [2][3]. Group 3: Environmental Impact - Upon full capacity operation, the average annual power generation is expected to exceed 10.2 billion kilowatt-hours, saving approximately 3.1 million tons of standard coal annually and reducing carbon dioxide emissions by over 8.3 million tons [3][4]. - The clean electricity generated will be transmitted through the Jinshang to Hubei ±800 kV UHVDC project to the Central China region, further optimizing China's energy structure and promoting a green and low-carbon energy transition [4].
