New results on offshore electricity grid infrastructure in Europe: the EU “OffshoreGrid” project analysis reveals tremendous cost saving potential. Report published in Brussels today.

Offshore grids, connecting North and Baltic Sea wind farms to electricity consumers, will be substantially cheaper to build than expected. Building “hub connections” at sea instead of using cables to connect single wind farms individually to the shore will result in investment costs that are 14 billion Euros lower. Additionally if these hub connections were combined with an even more interconnected “meshed grid”, the necessary additional costs of 5 to 7 billion Euros would be compensated by 16 to 21 billion Euros of additional benefits over 25 years of grid operation.
