On June 16, the first heliostat of the 100 MW CSP + 800 MW photovoltaic hybrid power project in Amdo, Tibet, was successfully assembled and installed. This marks a key milestone in the project’s construction and brings the world’s highest-altitude tower-type concentrated solar power (CSP) plant one step closer to reality.
The project employs cutting-edge molten salt tower CSP technology. Around 16,000 pentagonal heliostats, each covering 50.23 m², will direct sunlight onto a central receiver tower. The system heats molten salt to 560 °C, storing thermal energy that is then transferred via a counter-flow heat exchanger to generate mechanical energy and ultimately deliver stable, continuous clean electricity.
With a planned total investment of approximately 2.037 billion RMB (around €260 million), the plant integrates large-scale CSP with photovoltaic generation to enhance both renewable power output and grid stability. According to the project timeline, grid-connected operation is schedulded for October 2026.
