广西南宁抽水蓄能电站首批机组投产

Core Viewpoint - The first batch of units at the Guangxi Nanning pumped storage power station has been put into operation, marking a significant milestone in China's "14th Five-Year Plan" for major engineering projects [1][5]. Group 1: Project Overview - The Guangxi Nanning pumped storage power station has a total investment of approximately 8 billion yuan and is equipped with four units, which will be launched in two phases [5]. - The first batch of units will enhance the grid's regulation capacity by 1.2 million kilowatts, supporting the large-scale integration of wind and solar power in Guangxi [5][6]. Group 2: Operational Capacity - The newly operational units can convert 500,000 cubic meters of water into 600,000 kilowatt-hours of clean electricity per hour, sufficient to meet the daily electricity needs of 100,000 households [3]. - Once fully operational, the power station is expected to consume approximately 2.5 billion kilowatt-hours of clean energy annually, which will reduce carbon dioxide emissions by 2.2 million tons [6]. Group 3: Technology and Functionality - Pumped storage power stations operate by using excess electricity to pump water to a higher elevation during periods of high renewable energy generation, and then releasing it to generate electricity when renewable generation is low [8]. - China's installed capacity for pumped storage has exceeded 64 million kilowatts, providing robust support for the high-quality development of renewable energy [8].
