Core Viewpoint - The construction of the Shuangjiangkou Hydropower Station, a key energy project under China's 14th Five-Year Plan, is progressing rapidly, with significant milestones achieved, including the completion of the first water storage, which marks an important step towards its operational launch [1][3][17]. Group 1: Project Overview - The Shuangjiangkou Hydropower Station has an installed capacity of 2 million kilowatts and an average annual power generation of 7.7 billion kilowatt-hours [1][17]. - The dam, designed to be the highest in the world at 315 meters, has a total fill volume exceeding 46 million cubic meters, which could form a wall that wraps around the Earth's equator if constructed as 1-meter square sections [1][10]. Group 2: Construction Progress - The reservoir of the Shuangjiangkou Hydropower Station completed its first water storage, reaching a depth of over 90 meters, with a current water volume of 110 million cubic meters, equivalent to nearly 8 West Lakes [7][9]. - The dam's construction has reached a height of 205 meters, with plans to add another 110 meters [10][11]. - The project aims to achieve the first unit's power generation by the end of this year, contributing an additional 6.6 billion kilowatt-hours to downstream power stations, sufficient to meet the annual electricity needs of over 3 million households [17]. Group 3: Engineering Challenges - The rapid rise in water level during the initial storage phase posed significant challenges to the dam's quality and construction techniques, with an elevation increase of 80 meters in less than 20 days [9][11]. - The dam's structure features a trapezoidal design, with a base thickness of 1,400 meters tapering to 16 meters at the top, enhancing its stability against the immense pressure from upstream water [11][13]. Group 4: Historical Context - The construction of the Shuangjiangkou Hydropower Station began in July 2015, with key milestones including the river diversion in December 2015, the start of dam filling in April 2020, and the completion of underground powerhouse excavation in December 2022 [20].

Core Viewpoint - The construction of the Shuangjiangkou Hydropower Station, a key energy project under China's 14th Five-Year Plan, is progressing rapidly, showcasing the country's commitment to enhancing its energy capacity and infrastructure [3][6]. Group 1: Project Overview - The Shuangjiangkou Hydropower Station has an installed capacity of 2 million kilowatts and an average annual power generation of 7.7 billion kilowatt-hours [3]. - The dam, designed to be the highest in the world at 315 meters, has a total fill volume exceeding 46 million cubic meters, which could form a wall that wraps around the Earth's equator if constructed as a one-meter square wall [10][12]. Group 2: Recent Developments - On May 1, 2023, the reservoir of the Shuangjiangkou Hydropower Station completed its first water storage, marking a significant step towards operational readiness [6][8]. - The current water storage level has reached 1.1 million cubic meters, equivalent to nearly 8 West Lakes, with plans to raise the water level by over 150 meters by 2027 [8].
