安徽向前丨藏在大山里的“超级充电宝”

Core Insights - The article discusses the significance of the pumped storage power station in Jixi County, Anhui Province, which operates as a "super battery" to stabilize the power grid in East China without relying on coal, wind, or solar energy [1][2]. Group 1: Pumped Storage Power Station Overview - The pumped storage power station consists of an upper reservoir, a lower reservoir, a water transport system, and an underground plant, utilizing excess electricity during low-demand periods to pump water uphill for storage [1]. - The station has a total installed capacity of 1.8 million kilowatts, making it the largest pumped storage power station in Anhui Province, with six reversible units of 300,000 kilowatts each [2]. Group 2: Economic and Environmental Impact - As of 2024, the power station has generated a cumulative 2.479 billion kilowatt-hours of electricity and has responded to grid demands 106 times with a 100% success rate, significantly supporting peak shaving and clean energy consumption in the East China grid [2]. - The economic output of the power station in 2024 is reported at 1.684 billion yuan, contributing 113 million yuan in taxes and boosting local employment and infrastructure development [2]. - The environmental benefits include an annual reduction of approximately 216,000 tons of coal consumption and a decrease in carbon dioxide emissions by 475,000 tons, along with reductions in nitrogen oxides and sulfur dioxide emissions [2]. Group 3: Future Developments - Jixi County is advancing new pumped storage projects, including the Jixi Jiaping pumped storage power station, which has been approved with a capacity of 1.4 million kilowatts and an investment of approximately 8.4 billion yuan, expected to be operational by 2030 [3]. - Another project, the Shangzhuang pumped storage power station, is in the planning stage with a proposed capacity of 1.2 million kilowatts, aiming to enhance the resilience of the power grid and convert local ecological resources into economic advantages [3]. - As of August 2023, China's total installed capacity of pumped storage power stations reached 62.365 million kilowatts, achieving the target set in the 14th Five-Year Plan [3].
