The "SPM LTDS Appendix 7 Substation Abbreviation Codes (Table 7)" dataset outlines a standardised method of plant referencing in order to accurately identify equipment and locations for system analysis, network studies and network administration.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.Click here to access our full Long Term Development Statements for both SP Distribution (SPD) & SP Manweb (SPM).For additional information on column definitions, please click on the Dataset schema link below.Note: A fully formatted copy of this appendix can be downloaded from the Export tab under Alternative exports.Download dataset metadata (JSON)If you wish to provide feedback at a dataset or row level, please click on the “Feedback” tab above.
