广西首座抽蓄电站告捷

Core Viewpoint - The Nanning Pumped Storage Power Station, as part of China's 14th Five-Year Plan, is set to be fully operational by the end of 2025, marking a significant step in the development of a new energy system in Guangxi [1] Group 1: Project Overview - The Nanning Pumped Storage Power Station has an installed capacity of 1.2 million kilowatts, featuring four 300,000-kilowatt pumped storage units, and is the first independent pumped storage project approved, constructed, and put into operation within a single five-year plan in China [1] - The power station is expected to consume up to 2.5 billion kilowatt-hours of clean energy annually, leading to a reduction of 2.2 million tons of carbon dioxide emissions [1] Group 2: New Scenarios and Technologies - The construction site of the Nanning Pumped Storage Power Station showcases new scenarios, including the use of a tunnel boring machine that completed a 5-kilometer drainage tunnel in 460 days, achieving four times the efficiency of manual drilling [2] - The project has implemented a battery swap station for electric heavy trucks, allowing for quick battery changes in 3 to 5 minutes, which supports the green construction initiative [3] - The waterway system of the power station utilizes innovative materials, such as reinforced concrete, which saves approximately 10,000 tons of steel compared to pure steel materials [5] Group 3: Innovative Construction Methods - The project has adopted a new water storage method combining "large flow pumping" and "small flow stabilization" to address safety concerns related to the natural basin topography, achieving a water storage efficiency over 20 times that of natural rainfall [8] - The construction timeline from the start of the main project to full operation is only 41 months, reflecting a new speed in the construction of pumped storage projects in China [7]
