CGN's 750 MW Heishan Wind Power Project in Xinjiang Achieves Full-Capacity Grid Connection

en.Wedoany.com Reported - On November 7, the 750 MW Heishan wind power project built by China General Nuclear Power Group (CGN) in Jeminay County, Altay Prefecture, Xinjiang Uygur Autonomous Region, achieved full-capacity grid connection and commissioning. The project has installed a total of 75 wind turbine generators with a unit capacity of 10 MW each, supported by a 220 kV wind power collection station and transmission lines, with all units connected to the State Grid. The project is expected to generate approximately 1.88 billion kWh of electricity annually and has now officially entered the full-capacity grid-connected operation phase.

The project is located in Karjaw Township, Jeminay County, in the Irtysh River Valley wind zone. The wind farm adopts large onshore wind turbine generators with a unit capacity of 10 MW, with 75 units totaling an installed capacity of 750 MW. During construction, wind turbine installation, in-field collector lines, and supporting power facilities were implemented concurrently.

For the power transmission system, a new 220 kV wind power collection station was built. The electricity generated by the wind turbines in the field is collected through the collector system and then transmitted via one 220 kV transmission line to the State Grid Kanas 750 kV substation, connecting the wind farm to the regional main grid.

The project construction unit had previously advanced the supporting works for the wind farm collector lines. In May 2026, the Heishan wind power project completed the first lifting of an angle steel tower, entering the collector line construction phase. With the completion of unit installation and supporting transmission works, the project achieved grid connection of all installed capacity on November 7.

According to estimates published by CGN, once completed, the project is expected to supply approximately 1.88 billion kWh of clean electricity to the grid annually, equivalent to saving approximately 568,000 tonnes of standard coal and reducing carbon dioxide emissions by approximately 1.546 million tonnes per year. The above electricity and emission reduction figures are projected annual operating indicators for the project.
