How feasible is an interconnected offshore grid in the North Sea?

The NorthSeaGrid project, partly funded by the Intelligent Energy Europe (IEE) program, is the follow-up project of OffshoreGrid that investigated an optimal design for a meshed offshore grid directly building on and integrating offshore wind energy infrastructure.

NorthSeaGrid builds further on the results and investigates why these projects are not being built today. Instead of assessing another overall grid design for the North Sea, NorthSeaGrid carries out an in-depth analysis of three concrete case studies: the German bight, UK-Benelux and UK-Norway, and analyses the costs and benefits of integrated offshore grid solutions which are solutions that combine cross-border electricity transmission lines with offshore wind farm connections.

 

At the final event of the NorthSeaGrid project that will take place on 12 March 2015 in Copenhagen at the EWEA OFFSHORE event, the main project results will be presented and discussed with key stakeholders. The study shows that for these three cases, an integrated approach is more beneficial than an uncoordinated one where transmission lines and offshore wind farm connections would not be planned separately. However, costs and benefits are distributed asymmetrically between participating countries and stakeholders. Therefore, different cost-benefit allocation mechanisms have been examined, which could be the basis for bilateral or trilateral talks between affected countries.
