Formosa II is a 376MW offshore wind power project. It is planned in Taiwan Strait, Miaoli County, Taiwan. According to GlobalData, who tracks and profiles over 170,000 power plants worldwide, the project is currently at the partially active stage. It will be developed in multiple phases. The project construction is likely to commence in 2020 and is expected to enter into commercial operation in July 2022. Buy the profile here.


The project is being developed by Sea Wind Power. JERA, Green Investment Group, Stonepeak Partners and Swancor Holding are currently owning the project having ownership stake of 49%, 26%, 23.75% and 1.25% respectively.

The project is expected to supply enough clean energy to power 380,000 households, to offset 18,750,000t of carbon dioxide emissions (CO2) a year. The project cost is expected to be around $2,000m. The project will be spread over an area of 73.36km². The turbines will be mounted on fixed jacket foundations.

Development status

The project construction is expected to commence from 2020. Subsequent to that it will enter into commercial operation by July 2022.

Power purchase agreement

The power generated from the project will be sold to Taiwan Power under a power purchase agreement. The power will be sold at the rate of $0.188kWh for a period of 20 years. The capacity to be procured is 376MW.

Contractors involved

Siemens Gamesa Renewable Energy will be the turbine supplier for the wind power project. The project consists of 47 units of SG 8.0-167 DD turbines, each with 8MW nameplate capacity.

Siemens Gamesa Renewable Energy is expected to perform operations and maintenance for the Formosa II (Formosa II Phase I) for a period of 20 years.
