Qidong H3

Location

The Qidong H3 Offshore Wind Farm is located in the Yellow Sea, off the coast of Qidong City in Jiangsu Province, China. Specifically, it is situated about 38-40 kilometers offshore from the north side of the Yangtze River estuary.

Ownership and Development

The project is owned and developed by Jiangsu Huawei Wind Power Co Ltd, although the broader Jiangsu Qidong Offshore Wind Farm project, which includes H1, H2, and H3, involves coordination with other entities such as the East China Institute.

Capacity and Configuration

The Qidong H3 Offshore Wind Farm has a total installed capacity of 300 MW (or approximately 304,200 kW). This is part of the larger Jiangsu Qidong Offshore Wind Farm project, which has a total capacity of 802 MW and includes three independently approved wind power projects: H1, H2, and H3.

Turbines

The wind farm consists of multiple wind turbines, though the specific manufacturer for the H3 project is not detailed in the sources. However, the larger Jiangsu Qidong Offshore Wind Farm project includes a total of 134 wind power generators with 7 models from 4 different manufacturers.

Infrastructure

Each of the H1, H2, and H3 wind farms has its own 220kV sea booster station, and they jointly use an onshore centralized control center. This setup is China's first "three-station-in-one" offshore wind farm configuration.

Construction and Challenges

The construction of the project faced several challenges, including large swells, complex geological conditions, short construction windows during monsoon and typhoon periods, and tight schedules under epidemic prevention and control measures. Despite these challenges, the project team achieved records such as completing 14 single-pile sinkings by a single ship in a month and installing 31 wind turbines in a single month.

Environmental Impact

Once connected to the grid, the Qidong H3 Offshore Wind Farm, as part of the larger project, is estimated to generate 2.2 billion kWh of electricity annually. This will help save 766,000 tons of standard coal and reduce carbon dioxide emissions by 1.469 million tons annually, contributing significantly to achieving the goals of "carbon peak" and "carbon neutrality".

Commissioning and Cost

The Qidong H3 Offshore Wind Farm was commissioned in 2021. The estimated cost for the project is approximately €711.7 million.

Operational Status

The wind farm is operational and contributes to the overall energy production of the Jiangsu Qidong Offshore Wind Farm project.
