This project is the first million kilowatt offshore wind power project in Northeast China, marking the official start of large-scale development of offshore wind power in the Northeast China Sea and injecting a "booster" into the energy structure transformation of Northeast China.

In terms of project scale, the total installed capacity of the winning bid project is planned to be 1 million kilowatts, with a total of 112 offshore wind turbines with a single capacity of 9MW, supporting the construction of 1 220kV offshore boosting station, 1 onshore centralized control center, and a 50000 ton wind power operation and maintenance dock. After the completion of the project, it is expected that the annual power generation will reach 2.43 billion kilowatt hours, which is equivalent to reducing standard coal consumption by about 730000 tons and carbon dioxide emissions by about 2.4 million tons per year. The environmental benefits and energy supplement value are significant.

As the general contractor of the project, Electric Power Construction Central South Institute will be fully responsible for the survey and design, equipment procurement, engineering construction, and grid connection commissioning of the project. According to the project leader, the team will adopt anti ice wind turbines and low-temperature resistant submarine cable technology to ensure stable operation of the equipment in extreme temperatures ranging from -25 ℃ to 40 ℃, in response to special environments such as low winter temperatures and sea ice coverage in the Northeast China Sea. At the same time, five professional offshore construction ships will be put into operation during the construction phase of the project, and it is expected to achieve full capacity grid connected power generation by the end of 2026 through the "land sea cooperation" operation mode.

From a regional development perspective, the implementation of this project not only fills the gap of millions of kilowatts of offshore wind power in Northeast China, but also drives the development of local wind power equipment manufacturing, port logistics, operation and maintenance services and other industrial chains. During the construction period of the project, it is expected to create over 3000 job opportunities. After being put into operation, it will provide stable clean electricity for Liaoning power grid every year, helping Liaoning Province achieve the goal of "reaching 22% of non fossil energy consumption by 2030" and providing important support for the green transformation of the old industrial base in Northeast China.

Industry insiders analyze that this winning bid is another breakthrough in the field of deep-sea offshore wind power by the Central South Institute of Electric Power Construction. Its accumulated experience in low-temperature offshore wind power construction will provide a replicable "Liaoning solution" for the development of offshore wind power in northern coastal provinces of China. As the project progresses, the Northeast China Sea is expected to become a new growth area for offshore wind power development in China, following Guangdong, Fujian, and Jiangsu.

From technology implementation to industrial linkage, the promotion of this billion dollar wind power project is quietly reshaping the green industry pattern in Liaoning and even Northeast China. In the practical application of anti icing technology, the project team not only installed special anti icing coatings on the wind turbine blades, but also innovatively adopted the "blade electric heating and melting system" - when the sea temperature is below -5 ℃ and there is an ice warning, the system can automatically start the heating function to maintain the surface temperature of the blades above 5 ℃, avoiding the influence of ice adhesion on power generation efficiency. This technical solution has been simulated and tested in the Bohai Sea area, and can reduce the winter unit failure rate by more than 60%, providing a key technical reference for wind power projects in low-temperature waters in the north.

The synergistic effect of the industrial chain is gradually emerging in the project promotion. At present, the Central South Institute of Electric Power Construction has reached cooperation agreements with 12 local enterprises in Liaoning. Dalian Heavy Industry is responsible for customized production of ice resistant wind turbine hosts, Yingkou Port Group undertakes equipment sea transportation and port loading and unloading services, and a cable enterprise in Panjin specializes in the research and development of low-temperature resistant submarine cables. This "localized procurement+customized production" model not only reduces the transportation cost of project equipment by 18%, but also drives local enterprises to add 15 new wind power related production lines. It is expected to generate a supporting industry scale of over 5 billion yuan in the next three years. Taking Dalian Heavy Industry as an example, the 9MW anti icing unit developed for this project has successfully obtained orders for low-temperature wind power projects in Shandong, Hebei and other places after project delivery, achieving cross provincial transformation of technological achievements.

The social value of the project is also reflected in the two-way integration of ecological protection and improvement of people's livelihoods. To reduce the impact of construction on marine ecology, the project team adopts the "non sinking pile construction technology" to construct an offshore booster station. Through modular assembly and floating installation technology, it avoids the damage of traditional pile driving operations to the habitats of underwater organisms. At the same time, the wind power operation and maintenance base planned and constructed in Donggang City, Dandong has cooperated with local vocational colleges to establish a "Wind Power Operation and Maintenance Professional Orientation Class". The first batch of 50 students will participate in practical training during the project construction period and directly enter the operation and maintenance team after graduation to train professional and technical talents for the local area. According to calculations, throughout the entire lifecycle of the project (25 years), in addition to providing stable green electricity annually, it will also contribute over 1 billion yuan in tax revenue to the Dandong region, indirectly driving the development of related industries such as tourism and catering.

As the project officially enters the offshore construction phase in the third quarter of 2024, the prelude to the development of offshore wind power in Northeast China is accelerating. The relevant person in charge of Liaoning Energy Bureau stated that relying on the technology and industrial foundation of the project, Liaoning has launched the preliminary work of two offshore wind power planning areas in Liaodong Bay and the northern Yellow Sea. It is expected that by 2030, the total installed capacity of offshore wind power in the province will exceed 8 million kilowatts, becoming the core pillar of green energy supply in the northeast region. The Central South Institute of Electric Power Construction also plans to summarize the experience of the Liaoning project as the "low-temperature sea wind power development standard system", promote its inclusion in the national energy industry standards, and further assist China's offshore wind power industry in extending to a wider northern sea area.Editor/Bian Wenjun
