Ecowende, in partnership with Waardenburg Ecology, DHI, and Robin Radar, is conducting field research to evaluate the effectiveness of this approach. The trial aims to determine if a single red blade creates a visible “smear” effect that birds can more easily detect. While the optimal colors and patterns remain under study, red was selected for its balance of visibility, durability, and resistance to overheating.
Line Kyndi Behrens, Vestas’ technical project manager at Hollandse Kust West VI, explained: “Initially, colors like black and fluorescent were considered, but red was ultimately chosen based on performance criteria, particularly its ability to avoid overheating and ensure blade durability.” Vestas has tailored the production, transport, and installation of these non-standard blades to fit the project’s logistical constraints, including harbor storage and turbine assembly schedules.
The trial is part of Ecowende’s broader ecological strategy, which includes measures like adaptive curtailment and a designated bird corridor to minimize impacts on seabird populations. These efforts aim to exceed current industry standards for environmental protection in offshore wind projects. The research findings will be shared to inform future wind farm developments, balancing renewable energy production with wildlife conservation.
Thomas Haex, wind turbine engineer at Ecowende, stated: “By testing a wide variety of promising innovations, Ecowende aims to prove the most effective technologies. We share this knowledge to support future offshore wind projects, helping to minimize the impact on birdlife while maximizing renewable energy production—driving the energy transition in harmony with nature.”
Behrens added: “Many countries now emphasize ecological considerations in project permitting. While this specific initiative is still being tested and evaluated, it’s a valuable opportunity for us to explore what’s possible and prepare for evolving regulatory and environmental expectations. As a sustainability frontrunner in the wind industry, we see it as our responsibility to support such forward-leaning projects and contribute to shaping future ecological standards.”
The project underscores a commitment to advancing sustainable energy while addressing environmental challenges. By testing innovative solutions, Ecowende and Vestas aim to set new benchmarks for protecting birdlife in offshore wind developments, contributing to a cleaner and more harmonious energy future.
