NDP SPM Primary Group Polygons

Information

The "NDP SPM Primary Group Polygons" data table provides the geographic areas supplied by the primary substations, grid groups and GSPs in SPM.

The table gives the following information:

  1. Geo point for each primary group
  2. Geo shape for each primary group

Disclaimer

Whilst all reasonable care has been taken in the preparation of this data, SP Energy Networks does not accept any responsibility or liability for the accuracy or completeness of this data, and is not liable for any loss that may be attributed to the use of this data. For the avoidance of doubt, this data should not be used for safety critical purposes without the use of appropriate safety checks and services e.g. LineSearchBeforeUDig etc. Please raise any potential issues with the data which you have received via the feedback form available at the Feedback tab above (must be logged in to see this). 

The boundaries change periodically as our network evolves, e.g. if we add a new primary substation or interconnect primary substations.  These are the polygons that reflect the network at the time the DFES is published; other publications have their own sets of polygons where applicable.
