Core Viewpoint - The Hebei Fengning Pumped Storage Power Station, the world's largest in terms of installed capacity, has officially commenced commercial operation, contributing to energy security with green power [1][3]. Group 1: Project Overview - The Fengning Pumped Storage Power Station is located in Fengning Manchu Autonomous County, Chengde City, Hebei Province, with a total installed capacity of 3.6 million kilowatts [3]. - The annual designed power generation capacity is 66.12 billion kilowatt-hours, while the annual water pumping capacity is 87.16 billion kilowatt-hours [3]. - The project holds the world record for total installed capacity, energy storage capacity, underground plant chamber scale, and single underground plant scale, earning it the nickname "the world's largest power bank" [3]. Group 2: Construction and Technology - China Energy Construction Gezhouba Group Co., Ltd. is responsible for key construction tasks including the upper and lower reservoirs, water inlet and outlet, gate wells, and dam [3]. - The project management team has implemented advanced technologies such as digital dam management, rapid quality testing for roller compacted concrete, intelligent digital grouting, and slipform construction techniques [3]. Group 3: Energy Integration and Environmental Impact - The Fengning Pumped Storage Power Station is the first to connect to a 500 kV flexible DC grid, achieving multi-energy complementarity and enhancing the ability to absorb and deliver renewable energy [3]. - Since the first batch of units was put into operation in December 2021, the station has generated a total of 86.16 billion kilowatt-hours and absorbed 109.02 billion kilowatt-hours of renewable energy and off-peak electricity [3]. - Upon full operation, the station is expected to save 480,800 tons of standard coal annually and reduce carbon dioxide emissions by 1.2 million tons, playing a significant role in optimizing energy structure and reducing carbon emissions [3].
