National Grid's Future Energy Scenarios

Over the past few years we've been helping Northern Powergrid and UK Power Networks to visualise their Distribution Future Energy Scenario (DFES) data. The DFES data gives each Distribution Network Operator's yearly predictions until 2050 for various parameters - from numbers of electric vehicles to grid capacity - under four different scenarios and for different geographic areas. Similarly, National Grid ESO create Future Energy Scenarios (FES) but at a higher level in the distribution network - Grid Supply Points.

National Grid had already taken our DFES visualisation code (which we'd shared on Github) and created a visualisation of their 2021 data. As they wanted to add some new features and visualisations they asked for our help to create visualisations of their 2022 FES data.

The primary visualisation is a regional breakdown of parameters by Grid Supply Point and by region. This is largely based on our previous DFES visualisations. We've added the ability to download a CSV of the data for the current view. We've also added some extra notes to help explain the two different colour scale options as this is a common point of confusion - some people want to be able to compare different areas within a year and some want to compare the data over time.

We've added an experimental visualisation which lets you compare the FES data for two geographic areas side-by-side. The areas can by specific regions, one of the three nations, or Great Britain. The data is then displayed as heat maps, as line charts, and as a combined line chart. The line charts should help see patterns over time much more easily and the combined line chart lets you directly compare the two selections. It is experimental so please let us know what you think.

There are plans to add two more visualisations: one showing data for Local Authority heat model outputs and another for FES building block data. Expect these in the coming weeks.
