China has commissioned its newest offshore wind farm, which is also setting a record for the country’s deepest fixed-bottom wind turbines and is located far out to sea. The Huaneng Shandong wind farm, made up of 42 12MW turbines, was officially connected to the power grid and began delivering full power on April 7, 2026. Officials highlighted the complex geology and challenges of extreme sea conditions in developing and operating the 504 MW wind farm, the Huaneng Shandong Peninsula North L Site.
The wind farm was developed by the state-owned China Huaneng Group and will be managed and operated by the Yantai Power Plant.
The wind farm is located in northern China approximately 70 kilometers off the northeast coast of the Shandong Peninsula in the Yellow Sea. The position meant that the developers had to overcome the challenges of a 95.6-kilometer submarine cable to bring the power to the grid.
The location required the wind turbine foundations to be at depths ranging between 52 and 56 meters. It is the deepest position developed by China and rivals the deepest wind farm in the world – Scotland’s Seagreen 1GW Wind Farm, which is at a position of 58.7 meters, commissioned in 2023.
China Huaneng Group highlights the use of a four-pile jacket foundation structure with a maximum height of 83.9 meters to ensure the safety and stability of the turbines in the deep-sea and complex geological environment.
The project developed high-precision positioning technology using a navigation satellite system for the positioning of the foundations. The project was also able to reduce the pile driving time for a single wind turbine from 48 hours to 29 hours. The company expects the wind farm to save about 500,000 metric tons of standard coal per year.
