【新春走基层】秦皇岛：抚宁抽水蓄能电站建设正酣 “超级充电宝”加速成型

Core Viewpoint - The successful installation of the last unit's volute shell at the Hebei Funing Pumped Storage Power Station marks a significant milestone in the project, which is expected to enhance the capacity for renewable energy integration and improve the reliability and economic operation of the power system [1][3]. Group 1: Project Progress - The final unit, Unit 4, has completed the installation of its volute shell, contributing to the overall capacity of 1.2 million kilowatts for the pumped storage power station [1][3]. - The project has a total investment of 8.059 billion yuan and aims to have the first unit operational by 2027, with all four units expected to be connected to the grid by 2028 [3]. Group 2: Technical Details - The volute shell, weighing 176 tons and measuring 2.5 meters in height with a maximum diameter of nearly 12 meters, is crucial for the stable and efficient operation of the power generation units [1][3]. - The installation process required precision, with an allowable error of no more than 0.3 millimeters, ensuring that the volute shell was accurately positioned [2][3]. Group 3: Environmental Impact - The power station will have multiple functions, including peak shaving, energy storage, system backup, and black start capabilities, which will lead to a reduction of 105,200 tons of standard coal consumption and a decrease of 249,000 tons in carbon dioxide emissions annually [4].
