（活力中国调研行）探访世界坝体最高抽水蓄能电站：大号“充电宝”为华东电网注入绿色动能

Core Insights - The article highlights the significance of the JiuRong Pumped Storage Power Station as a major energy hub in Jiangsu, contributing to the green energy transition and addressing the challenges of electricity supply in the region [1][2]. Group 1: Project Overview - The JiuRong Pumped Storage Power Station is the highest of its kind in the world, located in the load center of the East China Grid, near key electricity consumption areas like Nanjing [2]. - Construction of the power station began in March 2017, with a total investment of 9.606 billion yuan, featuring six reversible turbine generator units with a total installed capacity of 1.35 million kilowatts [2]. - The power station consists of an upper reservoir, a lower reservoir, a water conveyance system, an underground powerhouse, and a switch station [2]. Group 2: Operational Impact - The power station plays a crucial role in peak shaving, frequency regulation, phase adjustment, and energy storage, helping to stabilize grid fluctuations and achieve time-space energy complementarity [2][4]. - Once all units are operational, the annual pumped water electricity generation is expected to reach 1.8 billion kilowatt-hours, with green electricity generation of 1.35 billion kilowatt-hours, sufficient to meet the annual electricity needs of approximately 360,000 households [7]. - The facility is projected to reduce carbon dioxide and sulfur dioxide emissions by about 357,000 tons annually, aiding in alleviating peak load pressure in Jiangsu and promoting the consumption of renewable energy [7]. Group 3: Technological Achievements - The dam of the JiuRong Pumped Storage Power Station stands at 182.3 meters, equivalent to the height of a 60-story building, showcasing significant technological advancements in constructing pumped storage facilities in flat terrain [4][7]. - The project has overcome multiple technical challenges, setting several world records and providing a replicable model for the construction of pumped storage power stations in high-load flat areas across the country [7].
