These maps show electricity data from our Future Energy Scenarios. They show a subset of the data available in our regional breakdown of FES data file and are intended as a demonstrator to facilitate feedback. We plan to use this feedback to help us refine the visualisation of our data in the future.

The demands shown are the typical demands that could be expected in each region at time of national system peak demand. Individually each region may experience higher demands as factors such as local weather conditions and local engagement with distributed energy resources impact demands at a local level throughout the year.

Transmission demands (such as large industrial customers connected directly to the transmission network) and transmission connected generation are omitted from this visualisation. The transmission demands are available to download from our data portal whilst the transmission generation aggregated by fuel type are available in our FES data workbook.
