On December 31, 2021, the first wind, solar and energy storage integrated demonstration project under China Energy Gansu Branch successfully began operation as the photovoltaic power grid-connected cabinet switched on.

With a total installed capacity of 40MV, the project takes use of the company’s existing 600MV wind power booster station and grid-connected lines, and gives full play to the mutual complementarity between wind power and solar power to enhance the power transmission efficiency. It fully demonstrates the company’s advanced ideas and technologies in reliable power supply and intelligent power utilization in terms of green energy. Throughout its life cycle, the project will generate electricity of more than 2.16 billion kVh, averagely supplying electricity of more than 86.53 million kVh to the grid each year. The project is expected to annually save nearly 265.66 million tons of standard coal and reduce carbon dioxide emissions by 86,273.4 tons, thus relieving environmental pollution and achieving coordinated ecological and economic development.
