京津冀｜70年官厅水电站“正青春”

Core Viewpoint - The article highlights the significance of the Guanting Hydropower Station as a cornerstone of China's hydropower development, celebrating its 70th anniversary and emphasizing its contributions to ecological sustainability and energy production in the Yongding River basin [1][2]. Group 1: Historical Significance - The Guanting Hydropower Station, inaugurated on December 26, 1955, was the first fully automated hydropower station designed and built in China, with a total installed capacity of 30,000 kilowatts [2]. - Upon completion, the station increased the power generation capacity of the Beijing-Tianjin-Tangshan grid by 14% [2]. Group 2: Modern Upgrades - In 2023, the Guanting Hydropower Station underwent its largest upgrade since its establishment, replacing units 1 and 3 with small-flow generators and overhauling unit 2 to enhance operational efficiency [4]. - The upgraded units can now achieve stable power generation at a flow rate of 10 cubic meters per second, effectively doubling the annual power generation capacity compared to previous levels [4]. Group 3: Ecological Impact - The Yongding River basin's hydropower stations have collectively generated 488 million kilowatt-hours annually, with Guanting contributing over 121 million kilowatt-hours, saving approximately 3 million tons of standard coal and reducing carbon dioxide emissions by about 8.24 million tons [6]. - The hydropower projects have executed 99 unified dispatch commands since 2021, ensuring a stable flow of 3.6 billion cubic meters of water, which supports the ecological integrity of the Yongding River [6].
