EDP Renewables, Mitsubishi Corp., Chiyoda Corp., ENGIE and Repsol create a consortium to implement a floating offshore wind farm in Portugal using Principle Power’s WindFloat Technology

  • The first Windfloat prototype © EDPRThe WindFloat Atlantic project envisages the construction of an offshore wind farm comprised of 3 or 4 wind turbines and a total capacity of 25 MW.
  • The project will be rolled out by Windplus, a consortium owned by EDP Renewables, Mitsubishi Corporation, Chiyoda Corporation, ENGIE and Repsol.

EDP Renewables (EDPR), Mitsubishi Corporation (through its subsidiary Diamond Generating Europe), Chiyoda Corporation (through its subsidiary Chiyoda Generating Europe), ENGIE and Repsol announce today an agreement to implement a floating offshore wind farm off the coast of Northern Portugal, known as the WindFloat Atlantic (WFA) project.

The project, located 20 km off the Portuguese coast at Viana do Castelo, is planned to be operational in 2018 and will consist of 3 or 4 wind turbines on floating foundations, accounting for a total capacity of 25 MW. WFA will benefit from the support of the European Commission, through the NER 300 program, and of the Portuguese Government through the Portuguese Carbon Fund. It was also selected for the InnovFin program by the European Investment Bank.

The first Windfloat prototype © EDPRThe consortium will use the WindFloat technology, an innovative semi-submersible foundation developed by Principle Power, Inc. This technology was already implemented in a first of its kind prototype called WindFloat 1 near Póvoa do Varzim. It comprises 2 MW Vestas V80 commercial wind turbine mounted on a WindFloat floating offshore wind turbine foundation.

The prototype has already produced more than 16 GWh over almost four years of operation – performing excellently through extreme weather conditions. Its successful results have been key for the creation of this consortium and the launch of the WindFloat Atlantic project, the aim of which is to demonstrate the economic potential and reliability of this technology, advancing it further in the path towards commercialization.

This project represents a key step forward in establishing the WindFloat technology as a leader in deep water offshore wind power generation.
