The North Seas Countries' Offshore Grid Initiative - Initial ... - Benelux

This study emphasises the importance of studying scenarios developed against common
foundations to avoid distortions created by differences within the scenario rather than
genuine market need. Both the radial and meshed approaches produce similar levels of
interconnection, with similar associated production cost savings, although there are
significant differences in how they were achieved (e.g. Norway-Great Britain link in the
radial design is replaced by Norway-Germany and flows through Continental Europe in the
meshed design). These differences need to be further investigated.
The addition of new offshore wind park connections and new interconnectors require
reinforcement of the onshore grids to accommodate the increased power flows through
the onshore networks. The onshore reinforcements are, with the exception of very small
differences in Great Britain, of the same order in both the meshed and radial cases.
