再创高原工程新纪录！全球海拔最高、西藏首个塔式光热电站吸热塔顺利结顶

Core Insights - The Tibet Kaitou Group has successfully topped the heat-collecting tower of the world's highest and Tibet's first tower-type solar thermal power station, the Anduo Tushuo 100MW solar thermal + 800MW photovoltaic integrated project, in just 233 days, setting a record for similar projects [1][2][4] Project Overview - The heat-collecting tower stands at 185 meters in the Tanggula high-altitude region, where the average annual temperature is -2.8°C and oxygen levels are only 60% of that at sea level [2] - The project utilizes 15,927 heliostats to focus sunlight onto the tower's top, heating molten salt to 565°C for energy conversion [2][4] Construction Achievements - The construction team overcame extreme cold and low oxygen conditions, achieving a vertical deviation of only 3 millimeters in the tower's structure [2][4] - Innovative techniques such as "layered thermal insulation pouring" and "electric heating" were employed to ensure concrete quality during construction [4] Project Significance - The project is a key energy initiative under Tibet's 14th Five-Year Plan, with a total capacity expected to generate approximately 260 million kWh annually, enough to power around 200,000 households [6] - It is projected to save 60,000 tons of standard coal and reduce carbon dioxide emissions by 165,000 tons each year, contributing to the development of clean energy in high-altitude regions [6]
