Wind farms at sea are the key to a successful energy transition. At sea the wind is strong and constant, and there is enough space to build wind farms which have several hundred megawatts of capacity.
However, planning an offshore wind farm makes high demands of the project team: environmental studies, water depth, shipping routes, tides and long distances from the coast make the planning a special challenge. To this, the permitting procedure of offshore wind farms, which in itself can take several years, is also very complex and multifaceted.
Unlike our onshore projects, we typically sell our offshore wind farms "ready to construct"; i.e. we have fulfilled all the prerequisites needed for permitting and the implementation phase can be immediately started followed by the subsequent construction. We are currently working on 13 projects and below you will find a detailed overview of our competences.
Our business model begins with the identification of a suitable area. Extensive surveys of biological, geological, oceanographic and meteorological conditions have to be performed, e.g. relating to marine environment, wind, waves, currents, and the sea bed floor on which the wind farm will be built. The further planning is based on the results of these studies.
In order to obtain the authorization to build an offshore wind farm, the project must meet extensive requirements. In coordination with the competent authorities and public agencies, we fulfill the requirements needed to develop the wind farm project to the point that it is ready for construction.
Offshore wind farms are located many kilometers off the coast. The grid connection and transportation of the electricity to land is the responsibility of the grid operator. Obtaining a grid connection is a central challenge of the project developer
and requires considerable legal and administrative expertise. For the offshore projects Gode Wind I and II and Borkum Riffgrund I and II, we have received a grid connection commitment from the grid operator TenneT.
At the time of the sale, our offshore wind farms normally meet all the conditions required to immediately begin with implementation stage. The planning is completed, all surveys have been integrated, the sea bed
floor examinations have been completed, the most suitable turbines, foundations and suppliers have been selected and the planning permission and grid connection have been secured. The buyer is therefore able to begin realizing the project right away.
After the project sale, we offer the buyer our advice and support and these consultancy services are integrated into various aspects of the realisation and operation phase.
We are currently working on six projects of our own in the German North Sea and acting as service providers for another five projects which we have already sold.
