What ETA Blades does
ETA Blades (legal entity ETA s.r.l.) is an Italian wind turbine blade designer, developer, and manufacturer founded in 2011. Its operational headquarters and composite manufacturing facility are located in Fano (Marche region), with a corporate office in Livorno. The company produces blades across two main segments — small rotors (Minieolico) for distributed/mini-wind installations and large rotors (Grandi Rotori) for utility-scale wind farms — using aero-elastic design methodologies and proprietary aerodynamic profiles. Its flagship product, the eTa4X, is engineered specifically for the re-blading of 600–800 kW turbines and has demonstrated a net AEP improvement of more than 20% with reduced structural loads and no additional acoustic emissions. The company is also advancing the MEWi-B (More Efficient Wind Blades) R&D project, focused on universal, recyclable aero-elastic blades operating across multiple wind regimes.
ETA Blades operates a B2B enterprise model targeting wind farm operators, asset owners, and turbine manufacturers. Revenue is generated through hardware (blade) sales and professional services including re-blading, retipping, design, moulding/tooling, and testing & certification. Re-blading offerings are priced either as discrete component transactions or via multi-year full-service management agreements; pricing is quote-based and not publicly disclosed. GTM is delivered through direct enterprise engagement supplemented by heavy participation in European industry events (WindEurope, TORQUE, AEE, Key Energy, WindEnergy Hamburg). Key disclosed customer relationships include Enel Green Power, ERG, and an unnamed major Italian energy player.
Since February 2021, ETA Blades has been part of the Nabla Wind Hub international group, formed through the merger of Nabla Wind Power, eTa Blades, and Romo Wind to deliver integrated "NextGEN wind solutions" and asset requalification services. The company holds ISO 9001:2015 and ISO 14001 certifications (DNV GL, 2021), received the Horizon 2020 Seal of Excellence in 2016 for the MEWi-B project, and was named among Enel/Symbola Foundation's "100 Italian Energy Stories" at COP21 in Paris. Its eTaGreen sub-brand codifies a circular-economy sustainability framework covering blade end-of-life, material reuse, and regenerative manufacturing.
