Green power transmission network fully operational, exporting 11 TWh from Gansu to Shandong

With the line now fully operational, the corridor is expected to transmit more than 11 billion kilowatt-hours of green electricity annually to Shandong and adjacent provinces in central and eastern China.

The delivery volume is equivalent to saving 3.5 million tonnes of standard coal and reducing carbon dioxide emissions by roughly 9 million tonnes each year, helping to ease supply pressure in one of China's largest power-consuming provinces while supporting its ongoing energy transition under the country's dual-carbon goals.

To boost capacity and efficiency, the project deployed high-strength aluminum alloy conductors with steel cores, raising transmission capability by about 30 percent. A mobile umbrella-type crossing frame, applied for the first time at this scale, improved line-stringing efficiency by 70 percent while sharply reducing onsite manpower demand.

The project also underpins Gansu's long-term energy development. Under the province's action plan to build a national new energy and equipment manufacturing base, Gansu aims to reach 80 gigawatts of installed renewable capacity by 2025.
