The world's first "dual-tower solo generator" solar thermal energy storage power station in northwest China's Gansu Province entered the commissioning phase on July 15, aiming for operation by year end. The power station features two adjacent heat-absorbing towers sharing a steam turbine generator, with nearly 30,000 heliostat mirrors installed, covering a light-collecting area of 800,000 square meters. It can also store excess solar energy with molten salt to achieve a 24-hour stable and uninterrupted power supply. Upon completion, the power station will complement surrounding photovoltaic and wind power to form a 700,000-kilowatt multi-energy complementary clean energy base. It is expected to produce 1.8 billion kWh annually, reducing carbon dioxide emissions by approximately 1.53 million tonnes.
