On April 30, a major milestone was achieved at the world’s highest-altitude concentrated solar power (CSP) tower project—the Tushuo 100 MW CSP plant in Amdo County, Tibet—where all 15,927 heliostats manufactured by Dongfang Boiler have been successfully delivered.
As a key energy project in the Tibet Autonomous Region and the region’s first tower-type CSP plant, the Amdo project is located in the Tanggula Mountains at an elevation exceeding 4,650 meters. The plant adopts advanced tower CSP technology and is equipped with an 8-hour molten salt thermal energy storage system. The total reflective area of the heliostat field exceeds 800,000 square meters.
To address manufacturing challenges under high-altitude conditions, Dongfang Boiler has independently established the world’s first intelligent heliostat production line designed for ultra-high-altitude environments. The facility enables fully automated operations across multiple processes, including adhesive filling and surface shape inspection, with a single production line achieving a daily capacity of 6,000 square meters—reaching industry-leading standards.
The project is scheduled to achieve full-capacity grid connection in 2026. Once operational, it is expected to generate approximately 260 million kWh of electricity annually, with around 2,551 utilization hours per year. The plant is projected to save about 60,000 tons of standard coal and reduce carbon dioxide emissions by 165,000 tons annually. It will supply electricity to approximately 50,000 households in Amdo County and surrounding areas, effectively alleviating winter power shortages in the northern Tibet grid.
