At 12:00 on September 21, the core structure of the solar receiver tower at the world's highest-altitude tower CSP plant—Tibet Kaitou Anduo County Tushuo 100 MW CSP Project—successfully reached the 100-meter elevation milestone. Located in Anduo County, Nagqu City, Tibet, the tower employs a hollow, thin-walled reinforced-concrete shell design with a total planned height of 185 meters. Completion of the 100-meter lift marks the project's transition into the most critical phase of superstructure construction.
Situated on the Tanggula Mountains at 4,645–4,657 m above sea level, the Anduo CSP plant has set a new world record for altitude among solar-thermal projects and offers a replicable “China solution” for clean-energy development in extreme high-elevation regions. Its smooth progress is vital for filling technological gaps in China's plateau clean-energy sector and for perfecting the nation's high-altitude CSP technical system.
The plant is invested in by Xizang Development Investment Group Co., Ltd and is being delivered under an EPC consortium led by Northwest Engineering Corporation Limited and POWERCHINA SEPCO1 ELECTRIC POWER CONSTRUCTION CO., LTD. Key equipment packages—covering the heliostat field, steam generator and turbo-generator sets—will be supplied by Dongfang Boiler Co., Ltd. Inner Mongolia Electric Power Survey & Design Institute Co., Ltd. serves as the project supervisor. Shouhang High-Tech Energy Technology Co., Ltd. won the direct air-cooled condenser package; Gansu Kaisheng Daming Solar Energy Technology Co., Ltd. secured the reflector mirror supply; Kearney (Jiangsu) Transmission Co., Ltd. will provide slew drives; and Beijing Aerospace Petrochemical Technology & Equipment Engineering Co., Ltd. is delivering safety valves for the steam-generator water/steam and molten-salt sides.
