We've created a map of the National Grid area that displays the carbon intensity for every substation, to give an overview of generation resources and how each substation compares to others in our area. Click on an area to view a summary of types of generation for that substation, and how much energy is locally generated.

You can control what is displayed on the map using the control fields above it. For the carbon intensity, you can set a date and time (within the range of our records or forecast) to see how the carbon intensity changes. The map can also be used to show other information for the substation, such as its assessed type (urban, rural etc. which helps understand what is likely to be possible in the way of local generation) and the overall level of renewables which are connected to it (measured by installed capacity, a theoretical maximum figure).

If you would like to know more about how we generate the information below, take a look at our FAQs. We also have a number of online Videos and Guides which tell you more about what we do in the community energy and network innovation areas.  These are available here. To find out more about what we do as a Company please view some of our videos in our video library.
