Floating offshore wind turbines in Portugal generate 25MW of green electricity annually and prevent the emission of 33,000 tonnes of CO2/year

Floating wind turbines, also known as marine wind turbines, offer numerous advantages. Positioned farther from the coastline, they capitalize on stronger and more consistent winds compared to their land-based counterparts. Consequently, due to their enhanced power output, floating wind turbines can generate up to twice as much energy as onshore turbines. However, installing these “offshore” wind farms in waters too deep for fixed-foundation turbines poses a challenge.

The ENGIE Solution: The world’s first semi-submersible floating wind farm

ENGIE collaborated with EDP Renewables, Repsol, and Principle Power to develop WindFloat Atlantic, leveraging innovative technology for harnessing wind power at depths exceeding 40 meters in Portugal.

Launched in 2020, WindFloat Atlantic utilizes cutting-edge technology designed by Principle Power, facilitating the installation of floating platforms in previously inaccessible deep waters, where abundant wind resources can be tapped. The wind farm, situated 20 kilometers off the coast of Viana do Castelo, Portugal, features three floating wind turbines, each boasting a capacity of 8.4 MW. Anchored firmly at a depth of 100 meters, akin to boats, these turbines supply the Portuguese electricity grid, meeting the energy needs of approximately 25,000 households.

Europe’s maiden floating wind farm, WindFloat1, underwent testing between 2011 and 2016 off the coast of Aguçadoura, Portugal. Despite encountering extreme weather conditions, including 17-meter waves and winds of 110 km/h, WindFloat1 generated 75 GWh of electricity in its inaugural year of operation. This successful prototype paved the way for the subsequent WindFloat Atlantic project, marking a significant milestone in the evolution of offshore wind energy.

WindFloat® technology: Due to its ability to be deployed in extremely deep waters, WindFloat® has the potential to tap into vast oceanic energy resources, addressing critical societal challenges such as the transition to clean energy, energy security, and climate change. In addition to providing solutions to these challenges, WindFloat® also brings opportunities for job creation, economic growth, and sustainable investment. This technology offers several advantages, including the ability for dry-dock assembly and towing without the requirement for specialized towing vessels, eliminating the need for complex offshore operations associated with the installation of conventional bottom-fixed structures. These features contribute to cost reduction throughout the lifecycle and mitigate risks. Moreover, the WindFloat® foundation has the capacity to accommodate the world’s largest available turbines, enhancing energy production capabilities and significantly lowering lifecycle costs.
