On April 19, the 100 MW tower-type concentrated solar power (CSP) project in Tuoshuo, Anduo County, developed by Xizang Development & Investment (Tibet Development Investment), achieved a key construction milestone with the successful hoisting of its steam drum, a critical core equipment component. The project is the first tower-type CSP plant in Tibet and currently the highest-altitude CSP project in the world.
This installation follows several previous major milestones, including generator stator installation and high-voltage module hoisting. The successful completion of the steam drum hoisting marks a significant breakthrough in the installation of key power-generation equipment, laying a solid foundation for subsequent system installation, commissioning, and on-schedule grid connection.
The project is a key energy initiative under China’s 14th Five-Year Plan in the Tibet Autonomous Region. Located at an extreme altitude of 4,650 meters, it is the world’s highest-altitude CSP project to date. The plant adopts molten-salt tower CSP technology and utilizes 16,000 heliostats (sun-tracking mirrors) to efficiently convert solar energy.
Once completed, the project is expected to save approximately 60,000 tons of standard coal and reduce carbon dioxide emissions by 165,000 tons annually. It will contribute to rural revitalization and the achievement of China’s “dual carbon” goals, while providing strong green energy support for the development of a clean energy base in northern Tibet.
