Short summary

As green energy demand rises, offshore wind farms in the North Sea are expanding. This study examines the uncertainties in power output predictions, considering turbine arrangements and different atmospheric situations. Using an advanced climate model, we found that power output can vary by up to 10 % due to these reasons. The findings are vital for accurate economic and environmental planning. This research will contribute to a better understanding of the potential of offshore wind energy.
