Figure 5-6 Radial Grid New Circuit Investment Costs for 2030 Reference Scenario (additional to TYNDP
projects)
The total of the investment costs of the optimised 2030 meshed grid design is 30 €bn.
These costs are displayed by country and asset type in Figure 5-7. In this case the Great
Britain share of the costs is reduced to about 33%, while the German and French
investment costs have increased. The changes in total cost for each country are displayed
in Figure 5-8. While the positions of individual countries change between the two designs,
the important point to note is that the overall costs are somewhat lower for the meshed
case indicating a potential benefit to the region of such meshed design. However, the
difference in overall costs is relatively small compared to the overall capital costs
reflecting the limited amount of meshing proposed in the meshed case for this Reference
Scenario.
