eTa Blades has introduced into the market the Re-blading concept with the aim to provide a solution for Performance Improvement and Life Extension. eTa Blades is among the Top companies of “Green Made in Italy” – a Sustainable Development Award promoted by the Foundation for Sustainable Development and by Ecomondo. The award has been granted because of the achievements in re-blading.
Today this activity is carried out within Nabla Wind Hub, the international group which merged eTa Blades, Nabla Wind Power and Romo. The international platform is able to offer exclusive redevelopment services for assets within the wind sector.
For wind farms already in operation which may have already exceeded the period of access to incentives or which, as they age, suffer from the decrease in expected yields Nabla Wind Hub offers blades with an innovative design that allow you to obtain more energy for longer. Furthermore, the retipping solution aims to increase the wind turbines rotor diameter in order to significantly affect energy production.
eTa4X was the first blade to be designed for the Re-blading of 600-800 kW turbines. It was also joined by eTa5X for 850 kW turbines.
The blades have obtained the Design Conformity Declaration from DNV-GL.
