The 1 million-kilowatt wind-solar power project in Qingyang, Northwest China's Gansu Province, started operation as the first 4.05-megawatt wind turbine began to run on Dec 21.
It was the first project to begin service at the Huaneng Longdong Energy Base, the country's first 10-million-kW multi-energy complementary comprehensive energy base.
The project is also one of the first national large-scale wind-solar power base projects located in the desert and Gobi areas.

With 759,000-kW of wind power and 241,000-kW solar power generator units, the project also included construction of two 330-kilovolt booster stations.
Upon operation, it is expected to generate more than 2.27 billion kWh of green power annually, equaling that produced by burning 680,000 metric tons of standard coal and a reduction of 167 tons of carbon dioxide. The power output can meet demands of 780,000 households for a year.
It's worth noting that the project is also the first new energy site that combines both wind and solar power generation units in China, a combination that improves land utilization rate, cuts down investment, raises wind-solar energy complementarity and power transmission stability, and provides technological support for future wind-solar energy generation and storage projects.
The smart and green Huaneng Longdong multi-energy complementary energy base has a total installed capacity of more than 10 million kW, more than 80 percent of which is clean energy. All projects at the base are scheduled to be put into operation within China's 14th Five-Year Plan (2021-25) period.
Once operational, the base is expected to export 24 billion kWh of power annually to East China’s Shandong Province through the ultra-high-voltage power transmission line.
The full operation of the base will help accelerate green transformation of local power structure, turn Gansu's resources into economical advantage and realize the country's "dual carbon" goals of peaking carbon dioxide before 2030 and reaching carbon neutrality before 2060.
The clean energy projects at the base are planned to have an installed capacity of 6 million kW, which includes 4.5 million kW of wind power and 1.5 million kW of solar power. Construction of the supporting energy storage facilities is also included. Once operational, the base is expected to generate more than 14 billion kWh of clean power, equaling that produced by burning 4.2 million tons of standard coal and a reduction of 11 million tons of carbon dioxide.
