Rudong H10

Location

The Rudong H10 offshore wind farm is located in the Huangshayang sea area, to the east of Rudong County, near Nantong city, in the Jiangsu province of China. Specifically, it is situated approximately 63 kilometers away from the shore.

Project Details

• Capacity: The Rudong H10 wind farm has an installed capacity of 400 MW.
• Turbines: The project comprises 100 wind turbine units, each with a nameplate capacity of 4 MW. The turbines are supplied by Shanghai Electric and are of the SWT-4.0-146 model. The rotor diameter of these turbines is 146 meters.

Site and Layout

• Area: The wind farm site measures approximately 8 kilometers in the east-west direction and 8.8 kilometers in the north-south direction, covering a total sea area of about 66 square kilometers.
• Water Depth: The turbines are installed at water depths ranging from 9 meters to 20 meters.

Foundations and Installation

• Foundations: The wind turbines are installed on monopile foundations. The installation was carried out using a 600-ton jack-up wind power installation platform along with 1,600-ton floating specialized marine equipment.

Power Evacuation

• Transmission: The electricity generated by the Rudong H10 wind farm is evacuated to the power grid through a combination of submarine cables, including a 35kV submarine cable, a 400kV flexible DC transmission submarine cable, and two 220kV AC submarine cables. The project also includes the construction of offshore and onshore converter stations and an offshore auxiliary platform.

Contractors and Developers

• Developer: The project is developed by Three Gorges New Energy Rudong Company, a subsidiary of the state-owned China Three Gorges (CTG) Corporation.
• Contractors:
  • Shanghai Electric Wind Power Equipment: Supplied the wind turbines.
  • Zhongtian Technology Group Offshore Engineering Company: Contracted for the foundation and installation of wind turbines.
  • East China Survey and Design Institute: Engaged in the design and engineering works.
  • Chongqing Waterway Engineering Bureau: Involved in the construction of the H10 offshore wind farm.
  • Jiangsu Power Construction No 3 Company: Contracted for the construction of the onshore converter station and the supply of auxiliary equipment for sea-land converter stations.
  • Nantong Ocean Water Conservancy Engineering Company: Awarded a contract for the construction of wind turbine foundations, booster stations, and submarine cable laying.

Environmental Impact and Benefits

• Annual Power Generation: The Rudong H10 wind farm is expected to generate up to 2.4 billion kWh of electricity annually, combined with the H6 wind farm, which can power approximately 990,000 households.
• Carbon Emissions Reduction: The project will offset up to 1.83 million tons of CO2 emissions annually by avoiding approximately 740,000 tons of coal consumption per year.

Construction and Operation Timeline

• Construction Start: The construction works on the project began in February 2020.
• Commercial Operation: The project entered into commercial operation in December 2021.
