In this sub-project, needs-based knowledge and recommendations for stakeholders involved in the planning and approval of the further expansion of offshore wind energy are derived, which not only focus on wind farm efficiency and yields, but also directly include environmental impacts. In the process, mesoscale modelling approaches for large-scale expansion are being further developed with regard to resolving wake effects and improving yield calculations.

In this sub-project, potentials and obstacles to the co-utilisation of wind energy with other land users (e.g. fishing, military, transport), but also through uses such as wave, tidal or solar energy, are being developed.

Based on interviews with stakeholders from research and industry as well as users of the maritime space, various co-utilisation scenarios are also being developed, e.g. for energy conversion and storage.

When large wind structures such as low-pressure areas or fronts move through offshore wind farms, this poses a major challenge for the electrical grid due to the magnitude of the affected power that needs to be integrated.

Therefore, a definition of system integration requirements for the modelling of yields is carried out. On this basis, the modelling and analysis methods for the time-dependent analysis of generation potential are being improved.

Studies on sustainable spatial and land use planning require accurate information on wind resources from mesoscale simulations.

A more precise modelling of coastal processes and the first analysis of operating strategies of offshore wind farms and co-utilisation concepts on the mesoscale are missing.

The issues and modelling requirements are identified together with the stakeholders.

The design of sustainable maritime spatial planning for the German Bight should also take into account uncertainties arising from the further development of the climate for wind resources in the German Bight.

The aim of the project is to develop a method that can be used to derive corresponding uncertainties.
