Qidong H1

Location

The Qidong H1 Offshore Wind Farm is situated on the north side of the Yangtze River estuary in Qidong City, Jiangsu Province, China. The center of the site is approximately 40 kilometers offshore.

Capacity and Configuration

• The Qidong H1 wind farm itself has a total installed capacity of 252 MW.
• However, it is part of a larger project that includes three independently approved wind power projects: H1, H2, and H3. The combined capacity of these projects is 802 MW, making it the domestic offshore wind power project with the largest single capacity in China.

Turbines and Manufacturers

• The entire Qidong Offshore Wind Farm project, including H1, H2, and H3, features a total of 134 wind power generators.
• These turbines are from 7 different models supplied by 4 manufacturers.

Infrastructure

• Each of the three wind farms (H1, H2, and H3) has its own 220kV sea booster station.
• There is also a jointly built onshore centralized control center, making this project China's first "three-station-in-one" offshore wind farm.

Environmental and Technological Significance

• The project is notable for being the first large-scale application of impressed current in China, which is a friendly approach for marine environmental protection.
• Once connected to the grid, the entire Qidong Offshore Wind Farm is estimated to generate 2.2 billion kWh of power annually, saving 766,000 tons of standard coal and reducing 1.469 million tons of carbon dioxide emissions. This is significant for promoting local industrial structure adjustments and achieving "carbon peak" and "carbon neutrality" goals.

Ownership

• The Qidong H1 Offshore Wind Farm is owned by Jiangsu Huawei Wind Power Co Ltd.

Construction and Operational Milestones

• The construction of the project faced several challenges, including large swells, complex geological conditions, and tight construction schedules during monsoon and typhoon periods, as well as under normalized epidemic prevention and control measures.
• Despite these challenges, the project achieved records such as completing 14 single-pile sinkings by a single ship in a single month and installing 31 wind turbines in a single month.
• The main part of the project was completed with the installation of the last wind turbine, marking a significant milestone in the development of large-scale offshore wind farms in China.

Completion and Commissioning

• The project was fully commissioned by the end of 2021, with the last wind turbine installed and the main part of the project completed.
