Innovation in the "100 MW multi-tower concentrated solar power system"

Date: 2026-02-09

CTG's "100 MW multi-tower concentrated solar power (CSP) system" has been recognized as one of 2025's top ten national energy technological innovations.

What's the breakthrough? The answer lies in its pioneering "multi-tower, single turbine" structure, which addresses the scaling limitations of the traditional "single-tower, single-unit" model. The multi-tower CSP system is now operational at the Guazhou 700MW "Solar Thermal Energy Storage+" project in Jiuquan, Gansu province. By integrating two solar towers with an unified heat storage and exchange system and a steam turbine generator, the project supplies approximately 1.8 billion kWh of clean energy annually, setting a new benchmark for efficiency and cost-effectiveness in the CSP sector.
