Xiangshui Demonstration

Location

The wind farm is located in the outer waters of Xiangshui County in Jiangsu Province, China.

Project Overview

This project is notable for being China's first offshore wind power project to transmit power via an offshore transformer substation. It was authorized by the National Development and Reform Commission in 2013.

Capacity and Turbines

The project has a total capacity of 202 MW. It includes two types of wind turbines:

• 37 units of 4 MW turbines
• 18 units of 3 MW turbines These turbines are based on high-rise pile cap foundations with a height of 146.5 meters and a hub height of 90 meters. Each turbine has a rotor diameter of 113 meters.

Grid Connection

The power generated by the turbines is transmitted to the grid through a 220kV offshore substation provided by ABB. The 35kV voltage generated by the turbines is stepped up to 220kV before being transmitted onshore via subsea AC cables, which feed clean wind power into the grid of Northern Jiangsu.

Environmental Impact

The project is expected to reduce CO₂ emissions by approximately 389,085 tons per year by replacing electricity generated by fossil fuel-fired power stations in the East China Power Grid.

Contractors and Construction

• China Offshore Oil Engineering (COOEC) was contracted for the booster station of the wind farm.
• CCCC Third Harbor Engineering received a contract for the foundation works and installation of the wind turbines. The construction involved onshore work and offshore transportation and installation, with all 55 turbines expected to be installed by October 2016.

Project Management

The project is managed by Yangtze River New Energy Development, which is established by China Three Gorges Project Corporation (CTGPC). The environmental impact assessment (EIA) was approved by the Jiangsu Environmental Protection Bureau in 2007.

Completion and Benefits

The project was scheduled for completion by 2016. Upon its completion, it is expected to enhance the local energy structure and generate significant social and economic benefits. The water depth in the operational area of the wind farm ranges between 8 and 12 meters.

Turbine Details Specific to Xiangshui

While the turbines used in this project are not specifically branded as Goldwind in the available sources, here are the key details about the turbines:

• Capacity: 3 MW and 4 MW
• Foundation: High-rise pile cap foundations
• Hub Height: 90 meters
• Rotor Diameter: 113 meters
• Grid Connection: 220kV offshore substation.

In summary, the Xiangshui Offshore Wind Farm is a pioneering project in China's offshore wind energy sector, emphasizing advanced technology and significant environmental benefits. However, it does not specifically involve Goldwind turbines, as the turbines mentioned are part of a broader Chinese wind energy initiative managed by different entities.
