The Huaneng Shandong Peninsula North L Site project has completed its full connection to the national power grid. This complex is located 70 kilometers offshore and operates at depths ranging from 52 to 56 meters, establishing itself as the deepest commercial facility in the Asian country to date.

Indeed, the installed capacity reaches 504,000 kilowatts through the synchronized operation of 42 wind turbines of 12 megawatts each. This infrastructure has the capacity to generate approximately 1.7 billion kilowatt-hours annually.
Likewise, the launch of this park will reduce standard coal consumption by 500,000 tons each year, strengthening the sustainability and decarbonization objectives of the Shandong region.
Regarding technical challenges, construction faced extremely complex geological conditions and ultra-long transport distances. To ensure turbine stability, four-pile jacket foundation structures with a height of 83.9 meters were implemented.
Precision on the seabed was achieved using the BeiDou Satellite Navigation System, allowing for a millimeter error margin during pile driving.
Subsequently, the use of intelligent assisted sinking technologies optimized execution times, reducing turbine installation from 48 to just 29 hours. The final interconnection relied on a 95.6-kilometer submarine cable, whose installation was supervised by drone systems and artificial magnetic fields.
