"Twin Tower Single Machine", the world's first multi-energy complementary project of wind-solar-thermal integration, was fully capped in Guazhou, Gansu, on October 12. The two towers, spaced 1 km apart, work in conjunction with 73 wind turbines and 48,897 PV components to pioneer new renewable energy base construction models.

Using molten salt heat storage, the project is China's first integrated wind-solar-thermal facility, expected to be completed by the end of 2024. With an annual generation of 1.8 billion kWh, it will save 560,000 tonnes of standard coal and reduce carbon emissions by about 1.53 million tonnes, promoting green energy transformation through exploring renewable energy integration and stable power output.
