Other project partners include EDP, Repsol, Portugal Ventures and A. Silva Matos.
During the testing, the WF1 system has undergone extreme Atlantic Ocean weather conditions, including waves exceeding 17m in height, and winds exceeding 60kt.
The partners validated the operational performance of the WF1, which also generated approximately 17 gigawatt hours of energy to the local grid while providing high levels of availability.
Principle Power board member and EDP Inovação executive director Luís Manuel said: "The WF1 is the most successful demonstration project in Portuguese Offshore Renewables, cementing Portugal, and the project partners, as global leaders in floating wind offshore.
"The technology has proven to be reliable and competitive. Now we want to bring it to the next level through a multi-unit project.
"We believe many more floating offshore wind projects will follow throughout the world."
The WindFloat project has now entered the final stage of the technology demonstration which involves the decommissioning of the system.
The final phase involves demonstration of WindFloat’s decommissioning risk, costs and environmental impacts.
Principle Power president and CEO Joao Metelo said: "We continue to incorporate all the learnings from this prototype into our current and subsequent designs and we look forward to delivering on our robust pipeline of projects in the coming years."
Principle Power said it is advancing the development of the WindFloat Atlantic project, a 3-unit, 25MW array of WindFloat systems, in Portugal. The project is backed by the EU’s NER300 scheme.
