SPM LTDS Appendix 7 Substation Abbreviation Codes (Table 7)

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). Each substation is assigned a unique four-character abbreviation code which is derived from the site name. This then permits plant and circuits to be identified by referring them to substation codes.

A unique node reference is obtained by appending two additional characters to the four-character substation code. The additional characters are generated to ensure that the node is uniquely identified and can comprise letters, alphabetic characters or a dash. By adopting this convention, all sites and equipment can be uniquely identified.

Any circuit or item of equipment simply connects two node points. For example, the 33 kV circuit between Ayr GSP and Heathfield Primary is defined as AYR-31 / HEFIT1.
