A municipal success story

Wittbek Citizen Wind Farm

Whether for the generation of energy for self-consumption, conversion into hydrogen or power-to-heat: citizen wind farms have great potential for communities and municipalities. GP JOULE offers everything that is critical to success – from a single source: from the necessary studies and concepts, public relations, project financing as well as legal and technical planning through to implementation, customer management and operations management.


We have been supporting ambitious local authorities in the realisation of their plans for many years. One of them is Wittbek in Schleswig-Holstein. The Wittbek community wind farm has been connected to the grid since September 2015 and GP JOULE ensures the commercially and technically flawless operation of the four 3 MW class wind turbines.
