# Abstract: This deliverable accompanies the slide pack Methodology & Key Inputs and is an Excel file of the Key Inputs. # Context: This knowledge building project aims to outline a number of price scenarios for the retail price of electricity across a number of different energy vectors in 2030. This project, delivered by Baringa, builds on their existing time series of hourly supplier electricity costs for 2030. They delivered an hourly electricity price series for 2030 based on traceable assumptions for three different 2030 supply-demand scenarios. The key objectives were: - To investigate the costs that domestic electricity suppliers in Great Britain might face in 2030. - To make projections on the assumption that, unless formally announced, no changes are made to the electricity market arrangements in place today - To focus in particular on the hourly variation and seasonal shape of supplier costs # Disclaimer: The Energy Technologies Institute is making this document available to use under the Energy Technologies Institute Open Licence for Materials.
