On January 11, 2026, the offshore wind power project of Huaneng Shandong Peninsula North L site was successfully connected to the grid for power generation, setting a new record for the deepest commercial offshore wind power depth in China. This marks a crucial step forward in the development of offshore wind power in China, injecting strong momentum into the national energy structure transformation and the achievement of the "dual carbon" goal.

The project is invested and constructed by Huaneng Shandong Branch, and operated and managed by Yantai Power Plant. The total installed capacity is 504000 kilowatts, and 42 Yuanjing Energy EN-252/12MW offshore intelligent wind turbines are deployed. The wind turbine fleet stands in the northern waters of the Shandong Peninsula, with an average depth of 53 meters and a center 70 kilometers offshore. It is the farthest offshore and largest single unit capacity offshore wind power project in Shandong Province.

According to calculations, after the project is fully put into operation, the annual power generation can reach 1.7 billion kilowatt hours, saving about 500000 tons of standard coal annually. The emission reduction benefits and energy supply value are outstanding. To cope with the complex geology and extreme sea conditions of the deep sea, the project innovatively adopts a four pile pipeline foundation structure, with a maximum height of 83.9 meters, setting a new height record for similar foundation structures in China. It can effectively resist the impact of harsh marine environments such as waves up to 6 meters high, ensuring the long-term safe and stable operation of the wind turbine.

Looking back at the development history of offshore wind power in Shandong Province, in September 2021, the EN-161/5.2MW wind turbine of Huaneng Shandong Peninsula South No. 4 offshore wind farm successfully produced the "first" offshore wind power in Shandong Province, achieving a breakthrough of zero. Over the past four years, the construction team has faced multiple challenges such as long offshore distances, harsh construction conditions, and tight schedules. Together with participating units such as Far East Energy, they have overcome a series of technical difficulties and ultimately achieved smooth grid connection of the project.

The operation of the Huaneng Shandong Peninsula North L site project not only demonstrates China's strong capabilities in offshore wind power equipment manufacturing and engineering construction, but also accumulates valuable experience for the large-scale development of offshore wind power, promoting China's offshore wind power industry to move towards deeper, farther, and stronger directions.Editor/Bian Wenjun
