1. Name of project
Formosa 4, Offshore Wind, Taiwan
2. Description of project
The project is an offshore wind development in the Taiwan Strait. The Project is expected to consist of 35 wind turbine generators (WTGs), each with a capacity of 14.14 Megawatts (MW). The project will have a grid capacity of up to 495 MW. The WTGs will be connected to one offshore substation (OSS) via 66 Kilovolt (kV) inter-array cables, and subsequently to the landing point through two export cables. The landing point is then connected to the grid through an onshore cable via an onshore substation (OnSS) which will be built as part of the project.
3. Location of project
Approximately 20km from the Western shore of Taiwan.
4. Source of environmental information
An Environmental Impact Assessment has been developed for the Project (Mandarin) along with various additional environmental and social studies (English) and a Non-Technical Summary (Mandarin and English). These documents can be accessed at the following weblinks:
