China: China Huaneng Group has successfully connected its 504 MW offshore wind farm off the Shandong Peninsula to the grid, with the project now running at full capacity.
The Huaneng Shandong Peninsula North development features 42 turbines, each with a capacity of 12 MW. Positioned around 70 km offshore in waters between 52 m and 56 m deep, it is described as China’s deepest commercial offshore wind project.
According to the company, the wind farm is expected to produce about 1.7 billion kWh of electricity each year. This output is equivalent to saving roughly 500,000 t of standard coal annually.
The project uses a four-pile jacket foundation design, with structures reaching heights of up to 83.9 m. This allows stable performance in challenging deep-sea conditions.
China Huaneng Group noted that construction involved overcoming difficulties such as complex seabed conditions, harsh weather and long-distance offshore operations. Advanced solutions were introduced to manage these challenges effectively.
The BeiDou navigation system was used to achieve highly precise positioning during pile installation, reducing installation time for each turbine foundation from 48 hours to 29 hours.
In addition, the project included the installation of a 95.6 km subsea cable, supported by drone-assisted work and magnetic field technology to guide placement.
The company said the project marks further progress in using large-capacity turbines and modern construction methods in deep and distant offshore environments, supporting the continued growth of China’s offshore wind sector.
