An official recent field test performed on a 660kW turbine equipped with the new blade by eTa Blades confirms Re-blading as an efficient solution for aging wind-farms
A recent field test, which has been officially performed on a historical Italian wind-farm owned by one of the most relevant Italian energy players and in collaboration with the top industry technical advisors, has shown that the adoption of the eTa4x blade – a specific blade designed and manufactured by eTa Blades – is able to deliver a net AEP increase of 20%+ if compared to the original blades, reducing loads on the turbine, with no additional noise emissions. Re-blading becomes therefore an available tool / strategy to eliminate the symptoms of aging on wind-farms.
Giovanni Manni, eTa Blades’ CEO, states that “This result has been made possible through the adoption of the most advanced design and manufacturing techniques: new aero-elastic concepts on innovative aero-dynamic profiles, linked to the adoption of new materials originally unavailable or not used for the manufacturing of wind blades. The target is to significantly enhance the cash flows of the assets, at the same time optimising the LCOE”.
eTa Blades, Italian wind blade designer and manufacturer, has introduced the concept of Re-blading in the wind industry to face the increasing need of reducing the impact of degradation on aging wind-farms and making marginal sites exploitable.
Re-blading is not just the possibility to purchase unavailable spare components, often out of production when it comes to old turbine models, but also the opportunity to increase the electrical output of the assets, reduce the OPEX, achieve a true life-extension.
eTa Blades has conceived two possible business models to offer Re-Blading: sale of components or long-term full-service.
