This project assessed the potential impact of selected, identified innovations on specific types of network (relating to heat, gas, electricity and hydrogen). Generic modelled networks will be developed utilising the 2050 Energy Infrastructure Cost Calculator model developed by a separate ETI project to understand the expected costs of certain types of network.The modelled networks will provide ‘business as usual data’ and a useful basis for further understanding of the impact of identified innovations in terms of overall cost and network performance.
This report considers electricity. Key points are:-Representative electricity transmission network model: Electricity networks modelled for 275kV and 400 kV network capacityThe increase in the costs is proportional to the increase in the network length for the same network capacity and installation date.For the same installation date, NPV total per km is higher for the higher capacity network.Representative Electricity Distribution Model: Electricity network modelled in rural, semi-urban, urban and London contextThe share of costs represented by each of the Assemblies changes slightly from 2020 to 2040, following the same trend in all contexts, except for London.Residential connections represent one of the highest costs in all contexts.The LV network makes a high contribution to total cost in the urban context while in London the LV substations make the highest contribution.First costs per capita increase as the context changes from rural through to urban areas.First costs per capita decrease slightly from urban to London contexts.The NPVs per capita increase as the density increases.One additional factor that influences costs in different contexts is their different lifecycle profiles.Generic upgrade costs at transmission scale: upgrading existing 275kV and 400kV lines to increase capacity by ~100%For the same installation date, Capex NPV per km is higher for the installation of a higher voltage network.Opex NPV per km is higher for higher voltagesRapid car charging: upgrading existing distribution networks to allow for connection of rapid car charging unitsCosts for the upgrade of the distribution network are dominant in all variations and contexts.For the same number of connection points at the same installation date the installation of rapid charge connections is more costly in the semi-urban context.he first costs and NPV per connection fall as the number of connections increases, which indicat...
