We are especially proud that Siemens Digital Industries Software has published a comprehensive case study on Eunice Wind and the EW16 Thetis wind turbine, showcasing how digital simulation and digital twin technology accelerate innovation in sustainable energy.
Eunice Wind, a subsidiary of the Eunice Group with headquarters in Mandra Attica, designs and manufactures advanced clean energy technologies, including wind turbines, hybrid energy systems and intelligent charging infrastructure. The company applies state of the art design methodologies, with a strong focus on quality, traceability and engineering excellence.
At the heart of the case study is the EW16 Thetis, a fifty kilowatt wind turbine that has been designed, certified and manufactured in Greece. The turbine holds type certification from TÜV Rheinland and NATO and has been successfully deployed in a wide range of environments, supporting both grid connected and autonomous applications, with proven reliability and high performance.
For the design and optimization of the EW16 Thetis, Eunice Wind collaborated with FEAC Engineering, an official Siemens partner, leveraging Simcenter STAR CCM+ to develop a highly accurate digital twin. Through advanced CFD simulations, including detached eddy simulation, transient wake flow analysis and unstructured meshing, the teams achieved automated and repeatable evaluation of multiple design variants under realistic wind and terrain conditions.
With the support of the FF4EuroHPC infrastructure, engineers from Eunice Wind and FEAC Engineering utilized high performance computing resources, reducing iteration time from one month to just one week and lowering total development costs by up to 83%. At the same time, digital simulations enhanced structural robustness through material fatigue prediction, load optimization and improved alignment between aerodynamic performance and manufacturability.
Blade pitch optimization resulted in a 1.5 % increase in energy output, while virtual material testing enabled an 8% reduction in blade weight. In parallel, automation of analysis workflows and report generation reduced reporting time by up to 70%.
Digital validation of the EW16 Thetis performance accelerated certification readiness and significantly reduced time to market, while strengthening confidence among investors, partners and customers. The digital twin also evolved into a powerful sales enablement asset, enabling evidence based demonstration of real world product performance.
Looking ahead, Eunice Wind plans to further expand the use of Siemens solutions across new development initiatives. These include the redesign of drivetrain systems and power electronics, as well as the integration of operational data through Simcenter SCADAS to support predictive maintenance and continuous performance optimization.
