The goal in the focus

All partner firms in the Group have a common goal: We promote energy using the the forces of nature.



Our thoughts and actions reflect our sense of responsibility and our attention to both detail and the big picture and hence are the foundations of our corporate philosophy. Get to know us. Here, we present our executive board.
