广西首个抽水蓄能电站上水库启动蓄水

Core Viewpoint - The initiation of water storage at the Nanning Pumped Storage Power Station marks a significant milestone in the project, transitioning into a full water storage phase, which is crucial for its operational readiness [1][5]. Group 1: Project Overview - The Nanning Pumped Storage Power Station is the first of its kind in Guangxi, consisting of an upper reservoir, lower reservoir, water conveyance system, and underground powerhouse [3]. - The total water storage capacity of the upper reservoir is approximately 4 million cubic meters, utilizing a combination of "large flow pumping" and "small flow stabilization" methods for efficient water transfer [3][6]. Group 2: Operational Efficiency - The entire water storage process is expected to take 32 days, facilitating subsequent water debugging and full-scale power generation [5]. - The innovative water storage method allows for completion in just over a month, achieving efficiency levels over 20 times that of natural rainfall storage, while ensuring the safety and stability of the dam [6]. Group 3: Capacity and Impact - The Nanning Pumped Storage Power Station has an installed capacity of 1.2 million kilowatts and is projected to be operational by the end of the year, with the potential to absorb up to 2.5 billion kilowatt-hours of clean energy annually [7].
