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 [3][4][8]. Group 1: Historical Significance - The Guanting Hydropower Station, inaugurated on December 26, 1955, is recognized as China's first fully automated hydropower station, contributing 14% to the power capacity of the Beijing-Tianjin-Tangshan grid at its inception [4][6]. - The station has played a crucial role in developing a complete domestic system for hydropower design, construction, and operation, fostering a generation of management and technical talent [4][6]. Group 2: Modern Upgrades - In 2023, the Guanting Hydropower Station underwent its largest renovation since its establishment, replacing units 1 and 3 with small-flow generators and overhauling unit 2 to enhance operational efficiency [6][7]. - The upgrades allow for stable power generation at a flow rate of 10 cubic meters per second, effectively utilizing the Yongding River's ecological water supply and increasing annual power generation capacity by nearly double [6][7]. Group 3: Ecological and Economic Impact - By December 26, 2025, the cumulative annual power generation of the Yongding River basin's hydropower stations is expected to reach 488 million kilowatt-hours, with Guanting contributing over 121 million kilowatt-hours, equivalent to saving approximately 3 million tons of standard coal and reducing CO2 emissions by about 8.24 million tons [7]. - The hydropower projects have also facilitated effective flood control and ecological management, successfully managing significant flood events and ensuring water flow throughout the Yongding River [7][8].
