我国海拔最高百万千瓦级光伏电站投产 参与构建全球最大水光互补项目群

Core Viewpoint - The successful grid connection of the Suorong photovoltaic project marks a significant advancement in the world's ultra-high altitude clean energy projects, contributing to the construction of China's first integrated water, wind, and solar energy base in the Yarlung Tsangpo River basin [1][3]. Group 1: Project Overview - The Suorong photovoltaic power station, located in Ganzi Tibetan Autonomous Prefecture, Sichuan Province, has a total installed capacity of 1 million kilowatts and an average annual power generation of approximately 1.98 billion kilowatt-hours [3][5]. - The project is expected to save 600,000 tons of standard coal annually and reduce carbon dioxide emissions by 1.64 million tons, thus enhancing the new energy system and ensuring national energy security [3][5]. Group 2: Environmental and Economic Impact - The project employs an ecological model of "pasture-solar complementarity" and "grass-solar complementarity," which allows for the unobstructed movement of yaks under the elevated solar panels, while also benefiting local grass growth through reduced soil moisture evaporation [3][5]. - As a key energy project in the national "14th Five-Year Plan" and the largest single investment in renewable energy in Sichuan during the same period, the Suorong photovoltaic station will optimize the regional energy structure and improve local infrastructure [5]. Group 3: Technical and Operational Challenges - The project faced severe challenges due to extreme natural conditions such as cold temperatures, low oxygen levels, strong winds, frozen soil, and significant temperature fluctuations, which were overcome through the technical and management experience accumulated from previous high-altitude renewable energy projects [5]. - The Suorong photovoltaic station will operate in conjunction with the nearby Kola photovoltaic station and the Yarlung Tsangpo River hydropower station, forming a world-class water-solar complementary project cluster with a total scale of 3 million kilowatts for both hydropower and solar energy [7].
