Energiekontor is a renewable energy company based in the German city of Bremen, with subsidiaries in Portugal and the United Kingdom. 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 over 90 wind farms across Europe in Germany, Portugal, Greece and the UK. The company detains a total power of 760 megawatt, which makes it one of the leading project developers in Europe. The investment was 1.2 billion euro since the establishment, with a total of 180 co-workers and an annual turnover of 160 million euro.
At a certain point, 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.
