11月7日，记者从南方电网储能公司了解到，国家"十四五"重大工程南宁抽水蓄能电站上水库正式 启动蓄水，标志着工程建设进入全面蓄水阶段，为年内投产创造有利条件。 本次蓄水的成功启动，综合检验了南宁抽水蓄能电站上下水库以及输水、发电系统的整体性能，为 国内在建抽蓄工程树立了高效蓄水的新范式。作为广西首座抽水蓄能电站，该电站装机规模120万千 瓦，建成后每年最多可消纳清洁能源25亿千瓦时。（陆权香 黄昉） 启动上水库蓄水，是抽水蓄能工程的一个重要节点。针对南宁抽水蓄能电站上水库大坝前方存在40 米高坑的特殊库盆地形，项目部在国内首创"大流量抽水"加"小流量稳压"的蓄水方式——利用电站已并 网调试机组的抽水功能，将下水库的水以每小时约25万立方米的大流量迅速抽至上水库进出水口前池， 再利用吸水装置，将前池积水以每小时2000多立方米的小流量排入大坝基坑，待大坝底部受压稳定后， 再将水灌入整个水库。 据了解，南宁抽水蓄能电站下水库已于今年1月启动蓄水，上下水库总库容1340万立方米，相当于 近一个西湖的水量。电站投产前，上水库需蓄水约400万立方米。 ...

Core Insights - The Nanning Pumped Storage Power Station in Guangxi has successfully passed the pre-storage acceptance test and is scheduled to begin water storage by the end of October 2023, laying a solid foundation for full production by the end of this year [1][5]. Group 1: Project Overview - The total scale of the Nanning Pumped Storage Power Station is 1.2 million kilowatts, with a total investment of approximately 8 billion yuan [5]. - Once completed, the power station is expected to consume up to 25 billion kilowatt-hours of clean energy annually [5]. Group 2: Construction Innovations - The construction of the power station incorporates green and intelligent practices, significantly enhancing production efficiency [3]. - The water conveyance channel, over 3.5 kilometers long, was built using reinforced concrete lining, saving about 10,000 tons of steel compared to pure steel channels [3]. - The project utilized mechanized construction for the excavation of the self-draining tunnel, achieving a fourfold increase in efficiency compared to manual drilling [3]. - The upper reservoir area features China's first heavy-duty electric truck battery swapping station, utilizing 20 electric trucks for transporting earth and stone, saving 680,000 liters of fuel annually and reducing carbon dioxide emissions by 1,800 tons [3].
