Lai Zhou offshore wind power and integrated development research and pilot project grid-connected power generation
On December 24th, the Laizhou offshore wind power and marine ranch integrated development research and test project successfully achieved grid connection of all 38 wind turbines, marking the successful completion of full-capacity grid connection of the nation's first offshore wind power and marine ranch integrated development research and test project.
Located in the national-level marine ranch demonstration area west of Furong Island in Tushan Town, Laizhou City, Yantai City, Shandong Province, the Laizhou offshore wind power and marine ranch integrated development research and test project is the nation's first offshore wind power and marine ranch integrated development research and test project jointly invested and constructed by China General Nuclear Power Group and Shandong Chengyuan Group. It is also a key project for incremental mixed-ownership reform in the new energy field approved by the National Development and Reform Commission and the National Energy Administration, with the EPC general contracting undertaken by China Power Construction South China Institute. The project site has a planned area of 48 square kilometers, an installed capacity of 304 megawatts, a total investment of 3.3 billion yuan, and is equipped with 38 of the most advanced 8-megawatt high-efficiency wind turbines in China, along with a newly built 220kV onshore substation.
The first wind turbine was installed on September 21st, the overhead lines were completed on November 5th, the onshore substation was successfully energized on November 25th, all wind turbines were installed on December 5th, and all submarine cables were laid on December 20th. The project has now achieved full-capacity grid connection, creating a domestic offshore wind power project with the lowest cost and shortest construction period.
The project can generate 1 billion kilowatt-hours of electricity annually. Compared with conventional coal-fired power plants, it can save about 300,000 tons of standard coal per year, reducing carbon dioxide emissions by about 780,000 tons, sulfur dioxide emissions by about 5,700 tons, and nitrogen oxide emissions by about 8,500 tons. The project practices the new and old kinetic energy conversion and high-quality development concept of “blue energy + offshore granary”, contributing to the achievement of the “dual carbon” goals, and providing a replicable and promotable new model for the integrated development of offshore wind power and marine ranches for Shandong and even the whole country.
Dalian Haien Gebhard Electrical Apparatus Co., Ltd. provided the fog horn obstacle light system and power distribution system for this project, providing a strong guarantee for the safe, stable, and reliable operation of the project.
