Nabla Wind Hub products

Generally, the design conditions of old wind turbines are very conservative compared to the reality of the sites where they are located, so they have a huge potential to be unlocked, in terms of life extension, performance improvement and maintenance optimization. In this sense, the retipping solution proposed by nabla wind hub aims to increase the rotor diameter of wind turbines in order to significantly impact in the energy Production. By upgrading the rotor of wind turbines with modular configurable tip extension designs, nabla manages to deliver Annual Energy Production (AEP) increases of up to 10% and a significant reduction in the Levelized Cost of Energy (LCOE). The objective of this solution is to achieve a redevelopment of the asset, reformulating the business plan for each wind farm, unlocking the hidden potential that the site-specific conditions are allowing.

nabla wind hub has introduced the concept of reblading wind turbine which represents not just the possibility to purchase unavailable spare components, often out of production when it comes to old turbine models, but the opportunity to increase the electrical output of the assets, reduce the OPEX, adopt a true Life Extension enabler.

Available pure data analytics tools do not match market expectations. These tools are centered only in some drive train components neglecting ageing of the main structural components which size the financial life expectancy of the asset (blades, hub, mainframe, main shaft, yaw, tower, foundation. Also, they are base the learning process on high uncertainty wind data based on nacelle anemometers and/or sensorics which do not represent the entire turbine behavior, delivering a reactive learning data systems that waits to be taught based on the experience. Therefore, they are not able to predict failures that have not occurred before, thus not able to identify failure modes or track root causes either.
