Chongqing - Chongqing's wind power manufacturer has marked a milestone with the delivery of the 100th 10-megawatt wind turbine to a wind power project in Xinjiang, as part of an effort to build China's first large-scale desert renewable energy base connected to an external transmission channel, local media reported recently.

The turbines, produced by China State Shipbuilding Corporation Haizhuang Windpower (CSSC Haizhuang Windpower) in Chongqing, are delivered to the Huadian Tianshan North Slope wind power project, which are powering clean energy generation for the Hami-Chongqing ±800 kV ultra-high voltage direct current transmission project, said the reports.

According to CSSC Haizhuang Windpower, production of the 100 turbines began last year and reached the 100th delivery in eight months. 

A CSSC Haizhuang Windpower representative said that the 10 MW units were specifically designed for the desert and Gobi environment, using mature high-speed doubly-fed drive train technology, load reduction control systems, and advanced power optimization design.

To address extreme conditions such as high and low temperatures and sandstorms, the turbines feature engineering adaptations aimed at ensuring economic efficiency, operational stability, and environmental resilience.

The "Jiangdian Ruyu" project began power transmission on June 10. The HVDC line connects Hami in Xinjiang to Yubei Converter Station in Chongqing, covering a distance of 2,260 km across Xinjiang, Gansu, Shaanxi, Sichuan, and Chongqing. Once fully operational, electricity generated in Xinjiang will reach Chongqing in seven milliseconds.

The project is one of 102 major infrastructure works listed in China's 14th Five-Year Plan. Upon completion, it will deliver over 36 billion kWh of electricity annually to Chongqing, increasing the city's power supply capacity by more than 20%. Clean energy will account for over 18 billion kWh of this supply, equivalent to replacing 5.9 million tonnes of standard coal and reducing carbon dioxide emissions by 15 million tonnes each year.
