From Planning to Operational Approval

Wind energy conversion only makes sense for operators and consumers if it is economical.

Project development with an investment volume of more than 2,1 billion euros have shown us just how to do this. Professional planning is the most important tool – starting with the choice of location and turbine layout, through the limitless variety of approval processes all the way to turbine selection and grid connection.

We welcome energy projects in any stage and will help you turn them into a success.




Maintenance and Repair

With our service, everything runs like clockwork, and around the clock. 

More than 95 employees at the headquarters and at 16 locations manage 1.400 of our own and third party wind turbines. 

Our team has twice the know-how:  that of a turbine manufacturer and that of an operator. Maintenance, inspection, preventive servicing and repair together with unique live and online monitoring technologies all ensure the economic success of turbines at calculable costs.
