UK Power Networks Secondary Substation Distribution Areas

Methodological approach The dataset is generalised using our GIS customer connectivity model. Each Secondary Substation's connected LV Network is traced out to its electrical extents, including all connected customers.

Using the geographic position of customer connections and key network points of both the Substation being traced and surrounding Substation's network, a Voronoi diagram is created. Each Voronoi polygon that intersects with the traced network is joined together to produce a single polygon, depicting the Supply Zone. Quality Control Statement The data is provided "as is".
