永定河山峡段4座梯级水电站累计发电破100亿千瓦时

Core Viewpoint - The four hydropower stations in the Yongding River Gorge section have collectively surpassed a cumulative power generation of 10 billion kilowatt-hours over 70 years, marking a significant milestone in China's hydropower development and contributing to energy supply and ecological restoration in the Beijing-Tianjin-Hebei region [1][7]. Group 1: Power Supply - The Yongding River Gorge hydropower stations have played a crucial role in supporting national industrial development since the commissioning of the Guanting Hydropower Station in 1955, which increased the power generation capacity of the Beijing-Tianjin-Tangshan grid by 14% [1][2]. - The construction of the downstream Xiaomaling and Xiayi Dian hydropower stations in 1961 and 1975, respectively, has established a solid framework for coordinated power supply in the region [2]. Group 2: Quality of Power - The hydropower stations have implemented intelligent and automated upgrades to enhance operational efficiency and reduce costs, ensuring reliable power supply while contributing to ecological restoration efforts [5]. - Since the implementation of comprehensive governance and ecological restoration of the Yongding River in 2016, the hydropower stations have actively participated in flood control, ecological replenishment, and water resource optimization [4][5]. Group 3: Green Power - The 10 billion kilowatt-hours of clean hydropower generated by these stations significantly contribute to Beijing's carbon neutrality goals, reducing fossil fuel consumption and carbon emissions [7]. - The clean energy produced is equivalent to saving approximately 3 million tons of standard coal and reducing carbon emissions by 7.25 million tons, providing clean energy for 2.7 million households in the Beijing-Tianjin-Hebei region [7].
