DemoSATH Floating Offshore Wind Project Powers Up, Pioneering Clean Energy in Spain

(IN BRIEF) The DemoSATH floating offshore wind project, led by Saitec Offshore Technologies in collaboration with RWE and KEPCO, has achieved a significant milestone by commencing electricity generation. Located off the Basque coast, the DemoSATH platform features a 2 MW turbine, equivalent to the annual electricity consumption of about 2,000 Spanish households. This project marks the introduction of floating offshore wind technology into Spain’s renewable energy mix. Over the next two years, the project will collect data on the behavior of the SATH technology and its interaction with the ecosystem, including monitoring of birds, bats, and marine biodiversity. It also aims to evaluate environmentally friendly solutions to support marine biodiversity and fishing resources in floating offshore wind farms. The project’s success is the result of collaborative efforts between technology developers, energy companies, supply chain partners, and government support.

(PRESS RELEASE) ESSEN, 19-Sep-2023 — /EuropaWire/ — The floating offshore wind project DemoSATH, led by the Spanish engineering firm Saitec Offshore Technologies, in collaboration with the German energy company RWE and the Japanese company Kansai Electric Power (KEPCO), achieves a significant milestone as it commences electricity generation.

In August DemoSATH was installed offshore at the BiMEP testing area at Armintza in the Basque Country. Subsequently, the connection of the existing static seabed cable to the motion-absorbing dynamic cable, and the link to the platform’s bow turret was successfully completed. This achievement enables the transmission of the generated electricity into the electrical grid through the BiMEP substation, converting the force of the wind into clean renewable energy.

The DemoSATH platform, located 2 miles off the Basque coast, features a turbine  with a capacity of 2 megawatt (MW). Its annual production is equivalent to the annual electricity consumption of approximately 2,000 Spanish households. As a result of this project, floating offshore wind technology is being introduced as a new renewable generation technology in Spain’s energy mix for the first time.

The commissioning marks the beginning of a two-year operational period to gather data about the behavior of the SATH technology, developed by Saitec Offshore Technologies, and the monitoring of the systems installed on the platform to understand its interaction with the surrounding ecosystem.

Specialized tools for the identification of birds and bats have been installed, as well as systems for monitoring marine ecosystem biodiversity (such as crustacean communities, other invertebrates, fish, and cetaceans) within the local environment. These monitoring activities will provide insights into the behavior of groups and species around the floating offshore turbine.

Additionally, the project will involve the evaluation of environmentally friendly solutions, custom-designed for SATH, which will aim to support marine biodiversity and enhance fishing resources in floating offshore wind farms.

The DemoSATH project represents a significant milestone in the floating offshore wind industry, becoming Spain’s first floating offshore wind turbine to connect to the electrical grid, the 5th European floating technology with a turbine of over 1 MW installed in open sea, and the 3rd concrete-based technology to reach this level of development.

David Carrascosa, COO at Saitec Offshore Technologies: “The start of energy generation from DemoSATH marks a culmination in the project. We are proud of the work accomplished and of being the pioneers in Spain in providing renewable energy with a floating wind turbine. This will be our testing ground to gain knowledge based on real-world experience and apply it in future larger-scale projects.”

Sven Utermöhlen, CEO RWE Offshore Wind: “We are glad to see that DemoSATH has been successfully commissioned. For us at RWE it is also another milestone on our way to unlock the great potential of floating wind globally, especially in countries with deeper coastal waters, like the US, France, UK, Norway and – certainly – Spain. Our ambition is to be a market leading floating wind player who safely develops, builds, and operates cost-competitive, commercial-scale floating wind projects around the world. Jointly with our other demonstration project, DemoSATH enables us to gain early experience for our future commercial-scale developments. Its unique concrete-based platform and single point mooring design further broadens our knowledge on innovative floating wind concepts.”
