Rudong H4

Location

The Jiangsu Rudong H4 Offshore Wind Farm is located in the Rudong Sea area, on the north side of the port boundary of Yangkou Port, in Jiangsu Province, China.

Capacity and Projects

The project is part of a larger development that includes two offshore wind farms, H4# and H7#. Each of these wind farms has an installed capacity of 400 MW, totaling 800 MW for the entire project.

Wind Turbines

The project involves the installation of 100 Shanghai Electric 4MW wind turbines for each of the H4# and H7# wind farms. This makes it one of the largest single-unit capacity offshore wind power projects in China.

Construction and Installation

• The construction includes the installation of wind turbines, with the first wind turbine of the H4# project successfully hoisted on November 10, 2021. The H4# project had completed the construction of 16 single pile foundations by then, while the H7# project had completed 8 single pile foundations.
• The wind turbines are hoisted using advanced technology, with the nacelle weighing 142 tons and the hub weighing 56.2 tons. The blades are hoisted individually, each weighing 19.6 tons, to an altitude of nearly 100 meters.

Infrastructure

• The project includes the construction of onshore and offshore infrastructure. This includes an onshore centralized control center and an offshore booster station. The land-based centralized control center was set to start electrical installation by the end of November 2021, and the sea booster station was scheduled to be shipped out to sea in December 2021.

Investment and Economic Impact

• The total investment for the project is approximately 14.8 billion yuan. For the year 2021, the project planned to complete an investment of 5.6 billion yuan.
• The project is expected to bring significant economic benefits to Rudong county, with over 90% of the offshore equipment provided by local enterprises. It is anticipated to generate more than 10 billion orders for the upstream and downstream enterprises in the Rudong offshore wind power industry, driving local economic growth.

Power Generation

• Once fully operational, the project is expected to achieve full-capacity grid connection by the end of the following year after the start of construction. The annual power generation is projected to reach 2.4 billion kilowatt-hours.

Completion Timeline

• The project aims to connect the first batch of units to the grid for power generation in the first quarter of the year following the start of construction. Full-capacity grid connection is expected before the end of the next year after the start of construction.

This project is a significant step forward for the State Power Investment Corporation in building large-scale offshore wind power bases in Yancheng and Nantong, and it plays a crucial role in the development of the offshore wind power industry in China.
