UK Power Networks has collaborated with Element Energy to develop an integrated top-down scenario planning tool which can be applied at the DNO level. The tool combines the UK Power Networks approach for modelling traditional load growth (i.e. domestic and commercial growth), with a number of low carbon technology models developed by Element Energy. The purpose of the model was to understand the overall impact on system peak demand for a range of economic and low carbon transition scenarios for each of our licence areas. The work is complementary to the Smart Grid Forum work but will provide the more detailed analysis required for investment planning
