Rudong H7

Location

The Jiangsu Nantong Rudong H7 Offshore Wind Farm is located in the Yellow Sea, off the coast of Jiangsu Province, China. Specifically, it is situated in the Rudong Sea area, north of the Yangkou Port boundary.

Capacity and Turbines

• The wind farm has an installed capacity of 400 MW.
• It consists of 100 wind turbines, each with a nameplate capacity of 4 MW. The turbines used are Siemens Gamesa SWT-4.0-146 models.

Development and Ownership

• The project was developed by Rudong Hefeng Offshore Wind Power and Shanghai Electric Power.
• The wind farm is currently owned by Shanghai Electric Power, which holds a 57% stake in the project.

Construction and Operation

• Construction on the project began in 2020.
• The wind farm entered into commercial operation in June 2021.
• The project involves the installation of wind turbines on fixed foundations, specifically using monopile foundations for both Phase I and Phase II.

Contractors and Suppliers

• The engineering, procurement, and construction (EPC) services for the project were provided by East China Survey and Design Institute, Jiangsu Zhongtian Technology, and Shanghai Electric Power.
• Shanghai Electric Wind Power Equipment was the turbine supplier for the project.

Technical Details

• The wind turbines were hoisted using advanced technology, with each turbine weighing 257 tons, including a nacelle of 142 tons and a hub of 56.2 tons. The blades were hoisted individually, each weighing 19.6 tons.
• The project includes the construction of onshore centralized control centers and offshore booster stations to support the operation of the wind farm.

Power Generation

• The Jiangsu Nantong Rudong H7 Offshore Wind Farm generates approximately 1,260,000 MWh of electricity per year.

Economic Impact

• The project is significant for the local economy, with more than 90% of the offshore equipment provided by local enterprises in Rudong. This includes the wind power main engine assembled by Shanghai Electric, steel pipe piles and towers supplied by Haili Wind Power, and submarine cables provided by Zhongtian Technology Group. The project is expected to bring over 10 billion yuan in orders to the local industry chain, driving economic growth in the region.

Environmental and Industrial Significance

• The project is part of China's efforts to expand its offshore wind power capacity and contribute to the country's renewable energy goals.
• It marks a major step forward for the State Power Investment Corporation in building large-scale offshore wind power bases in Yancheng and Nantong.
