World Energy Day is celebrated annually on May 29th. The commemoration of this day aims to sensitize people and government leaders to save energy and to promote renewable energies, more environmentally friendly, replacing fossil energies highly polluting and harmful to life on Earth.
In Portugal, the celebration of this day began with an initiative of the General Directorate of Energy of Portugal, on May 29th, 1981. However, some people celebrate World Energy Day, on October 22nd, due to an initiative launched by the World Energy Forum in 2012.
With 30 years of experience, Energiekontor is continuously working on innovation and developing new solutions, with maximum efficiency, in order to achieve harmonious and conciliatory interaction with the environment, landscape, fauna and flora, integrating a complete concept of Clean Energy.
Technical innovations, such as Rotor Blade Extension – RBE, are part of the strategy to improve and optimize the performance and yields of wind farms.
How Rotor Blade Extension project was born?
To improve the energy production at its own wind farms, Energiekontor requested fk-wind, from the Hochschule Bremerhaven (Germany), to study possible solutions for this problem. The conclusion was that wind turbines have to be improved or repowered. Repowering was not an economic solution and some wind farms even cannot be repowered due to a denied building authority approval.
In 2009, fk-wind presented a solution for increasing the rotor diameter with an extension of the blade, and that was clearly recognized to be the best compromise for an effective realization – RBE – Rotor Blade Extension.
RBE is an innovative modification product, currently available on the market, that increases wind turbine efficiency and provides AEP increase. Therefore, Energiekontor has applied this technology in wind farms in Germany and Portugal.
