In the bottom-right corner of the tool above there is an 'open in new window' which might make viewing the maps easier.
The ENA demand and investment drivers heatmap data has been gathered from lines companies using a simple survey. The data in the heatmap is the best estimation of some of the drivers of demand and the scale of network investment required to support it, over the coming three decades. As the data looks out further into the future, there are significant uncertainties around these estimates, and we should bear this in mind. Refer to individual lines company Asset Management Plans (AMPs) for definitive information about specific investment plans. These can be found on the relevant lines company websites.
Pease also be aware that the majority of the drivers identified here are a product of consumer choices (for example, purchase of EVs). Therefore, this data should not be interpreted as lines companies choosing which drivers to support. But rather, their estimation of the technologies and behaviours consumers will adopt at what time, and to what extent, and then their necessary response to support these.
Lastly, the estimated increases in network investment presented here should not be interpreted as directly corresponding to increases in network costs. While the two are related, there is not a one-to-one relationship between these.
