Figure 5-8 Comparison of Radial and Meshed Grid Costs by Asset Class for 2030 Reference Scenario
Figure 5-8 shows cost differences across the different types of asset. The chart shows that
the two designs have similar costs across most asset types, but AC offshore and
substation costs are somewhat higher for the radial design.
