Windfloat Atlantic is a semi-submersible floating wind farm. The project is a consortium led by a joint venture of EDP and Engie, Ocean Winds, and also includes Repsol and Principle Power Inc.
Windfloat Atlantic is the world’s first semi-submersible floating wind farm, led by EDP Renovables in northern Portugal, and generated 75-gigawatt hours (GWh) during its first year. There are three 50-meter turbines anchored to the seafloor, with a total installed capacity of 25 megawatts (MW) and capable of withstanding wind gusts of 100 kilometers per hour and 20-meter waves.
The first of the three platforms of the WindFloat Atlantic project was successfully connected in December 2019, after the installation of the cable that runs the 20 kilometers of distance that separate the wind farm and the station installed in Viana do Castelo. In May 2020, the project took another decisive step with the departure of the third, and last, of the three platforms off the coast of Viana de Castelo. Since it became 100% operational, the wind farm is able to generate enough energy to supply the equivalent of 60 thousand inhabitants per year.
WindFloat Atlantic uses advanced technology from Principle Power, which makes it possible to install floating platforms in deep waters, previously inaccessible, and where abundant wind resources can be harnessed. The wind farm will be located 20 kilometers off the coastline of Viana do Castelo, where the waters reach a depth of 100 meters.
WindFloat Atlantic has an O&M base in the port of Viana do Castelo, from where the team receives all the information in real-time from the wind farm and controls the different issues that may arise and require on-site intervention, which is complex due to the adverse weather and sea conditions in the wind farm area in the Atlantic Ocean.
Windfloat is designed to operate for 25 years and currently has a permanent staff of 12 people who service and operate the park on a full-time basis.
