高原绿色能源“超级充电宝”迎关键突破 一文了解

Core Viewpoint - The Sichuan Yalong River Lianghekou Pumped Storage Power Station, the largest mixed pumped storage power station under construction globally, has reached significant milestones with the completion of the excavation of the power station building and the commencement of concrete pouring for the downstream reservoir [1][2]. Group 1: Project Progress - Over 1,000 builders have been working during the Spring Festival to ensure the project timeline, taking advantage of the dry season for construction [2]. - The underground powerhouse, located about 500 meters deep in the mountain, is designed to house four pumped storage units, which will allow for both power generation and water pumping [7][18]. - The construction site is characterized by challenging conditions, including nighttime temperatures dropping to -10°C, yet the work continues vigorously [5]. Group 2: Technical Aspects - The mixed pumped storage power station will utilize both upstream water flow and water from the downstream reservoir, distinguishing it from conventional pumped storage stations [16]. - The facility will have a total installed capacity of 4.2 million kilowatts, including four reversible pumped storage units of 300,000 kilowatts each, capable of absorbing approximately 7 million kilowatts of wind and solar energy [18]. - The project is designed to provide dual functions of water pumping and power generation, effectively balancing peak and off-peak electricity demands [20]. Group 3: Strategic Importance - The Lianghekou Pumped Storage Power Station is a core component of the Yalong River basin's integrated water, wind, and solar energy base, which aims to enhance the stability and reliability of clean energy supply [21][24]. - The entire Yalong River basin is planned to have an installed capacity of 78 million kilowatts by 2035, with current operational and under-construction capacities contributing significantly to national clean energy goals [22]. - Once completed, the facility is expected to generate approximately 200 billion kilowatt-hours of clean electricity annually, sufficient to power around 110 million households [24].
