EHV Substation Combined Service Areas

Our EHV Substation combined service areas dataset provides an interactive shapefile to indicate the service areas of our Grid Supply Points, Bulk Supply Points, and Primary substations. Users can filter for each of these substation levels using the left hand panel.
These shapefiles show where the bulk of connections to each substation can be found. There could be cases where large, individual connections will fall into the shapefile of one substation, but is in fact supplied by a neighbouring site.
