The Jiangsu Rudong (H4, H7) wind power project is an 800MW project comprising two offshore wind farms, namely H4 and H7 in Rudong Sea, Jiangsu Province, China.
Estimated to cost approximately £1.67bn ($2.06bn), the offshore wind power project is owned and being developed by China’s State Power Investment Corporation (SPIC).
The Jiangsu Rudong H4 and H7 wind farms will be operated by Rudong Hefeng Offshore Wind Power Company and Rudong Haixiang Offshore Wind Power Company.
The construction works on the project were started in May 2020, while both the wind farms are expected to be operational by December 2021.
Upon commissioning, the Jiangsu Rudong (H4, H7) offshore wind power project is expected to generate up to 2.5 billion kWh of electricity annually.
Location and site details
The Jiangsu Rudong (H4, H7) wind power project is located offshore Rudong County, Nantong city, in the Jiangsu province of China.
While the Rudong H4 wind farm site lies on the north side of the Yangkou Port boundary with the centre of the site is located approximately 33km away from the shore.
The Rudong H7 wind farm site is situated in the northeast corner of the Rudong Sea area with the center of the site lying approximately 62km away from the shore.
The total planned sea area for the wind farms is about approximately 130km2, while the water depth ranges from 16m to 19m.
Rudong (H4, H7) wind farm make-up
The Jinagsu Rudong H4 and H7 offshore wind farms will be equipped with 100 4MW wind turbines from Shanghai Electric for an installed capacity of 400MW each.
The project also involves a 35kV inter-array cable system, two 220kV sea booster stations, a 220kV submarine export cable, and two onshore centralised control centers.
A consortium of East China and Design Institute, Shanghai Electric, and Zhongtian Technology entered into a general engineering, procurement, and construction (EPC) contract with SPIC for the H4 and H7 Offshore wind farms in April 2020.
East China Survey and Design Institute was engaged in the design and engineering works of the offshore wind farms.
Shanghai Electric is responsible for the supply of wind turbines, while Haili Wind Power Company has been engaged for the supply of steel pipes and towers.
Zhongtian Technology Group has been engaged in the supply of submarine cables for the project.
Rudong (H4, H7) wind farm project background
The preliminary work for the Rudong (H4, H7) Offshore wind power project was approved by the Rudong County Energy Bureau in July 2018.
The Rudong H4 and H7 offshore wind farms are expected to annually generate up to 1.2 billion kWh and 1.26 billion kWh of electricity respectively.
The project, once fully functional, will offset 768,000tonnes of coal consumption and 1.632 million tonnes (Mt) of CO2 emissions a year.
