Energiekontor and Rotor Blade Extension

Energiekontor and Rotor Blade Extension

Energiekontor is a renewable energy company based in the German city of Bremen.  In addition to its headquarters in Bremen, Energiekontor has offices in Bremerhaven, Hagen im Bremischen, Aachen, Bernau near Berlin, Potsdam and Augsburg. The company also has branches in England (Leeds), Scotland (Edinburgh, Glasgow), Portugal (Lisbon), USA (Austin / Texas and Rapid City / South Dakota) and France (Toulouse, Rouen).

The Group was founded in 1990 as a private and independent company to plan and develop wind farms. In 2002, was listed on Frankfurt securities exchange.

Since 1990, Energiekontor has developed 126 wind farms and 10 solar parks with a total capacity of over 1 gigawatt (GW). This corresponds to an investment volume of approx. wind and solar parks that have been realised produce more than 2 billion kilowatt hours (kWh) of electricity per year. This corresponds to the electricity requirements of a large city like Hamburg.

Energiekontor analyzed the production on own wind farms equipped with wind turbines type Bonus 1.0 and Bonus 1.3, and realized that some of them didn’t have the expected production.

To improve the energy production on those 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 a product that increases the efficiency of wind turbines. Therefore, Energiekontor has applied this technology in wind farms in Germany and Portugal.

Energiekontor is continuously working on innovation and developing new solutions, with the maximum efficiency, in order to achieve harmonious and conciliatory interaction with environment, landscape, fauna and flora, integrating a complete concept of Clean Energy.
