WindFloat Atlantic is now fully operational and supplying clean energy to Portugal's electrical grid. Following the connection of the last of three platforms to the 20 km export cable connecting the wind farm to the substation at Viana do Castelo, Portugal, the construction of the wind farm is now complete.

The project has a total installed capacity of 25 MW and is one of the world’s first semi-submersible floating wind farms. It is expected to generate enough energy to supply the equivalent of 60,000 users per year.


The project is led by the Windplus consortium, comprising EDP Renewables (54.4%), ENGIE (25%), Repsol (19.4%) and Principle Power Inc. (1.2%). Windplus installed and connected three floating wind platforms - measuring 30 m in height with a 50 m distance between columns. Each is able to accommodate an 8.4 MW turbine, the largest ever installed on a floating platform.

The platforms have been built jointly by the two Iberian countries: two of them were manufactured at the shipyards in Setúbal (Portugal), while the third was constructed in Avilés and Fene (Spain).


Its mooring technology allows for installation in waters over 100 m deep, and its design offers stability in adverse weather and sea conditions. According to Windplus, its Dry-dock assembly has provided logistical and financial savings with the platforms towed to the offshore site using standard tug boats.


The floating technology was implemented in a first of its kind prototype,
WindFloat 1, near Póvoa do Varzim, which was installed back in 2011. The project was a full life cycle demonstration featuring a Vestas V-80 2 MW turbine, and was decommissioned last year.
