SPM LTDS Appendix 3 System Loads (Table 3) HV Historic

The "SPM LTDS Appendix 3 System Loads (Table 3) HV Historic" dataset provides the previous years demand contribution, for each substation in a group, to the corresponding groups maximum demand.

Generation is connected to a number of primary substations and BSPs. This has the effect of supporting/offsetting local demand. Therefore the stated maximum demands for these locations may be lower than the connected load, if these generators were operating at the time of the maximum demand. Similarly, significant generation in the form of Combined Heat & Power (CHP) schemes can be embedded within customers' installations, which can have the effect of reducing the demand at their supply point and consequently the demand of the corresponding Primary substation or BSP.
