Renewable energy systems are becoming vital in fulfilling global energy demand. In this context offshore renewable energy resources constitute an important sector in which to invest to reach the ambitious decarbonisation targets. As renewable energy sources, they are affected by weather and climate, resulting in significant spatial and temporal fluctuations hence complicating power grid stabilisation. Offshore renewable energy sources, whenever available, offer significant potential to enhance the reliability of renewable energy systems by complementing each other across temporal and spatial scales. Specifically, the integration of co-located systems within a single power station presents a viable approach to manage the natural variability of renewable energy sources.
