Half Hourly (HH) Estimation During COVID-19

The below guidance only relates to HH Import Metering Systems. For Export Metering Systems, the current estimation rules remain applicable.  BSCP502, paragraph 4.2.2a requires that HHDC estimate zeroes “until such time that evidence of Export energy transfer is provided”. In the current circumstances, Suppliers and HHDCs should not take too narrow a view of what sort of evidence is acceptable (for example, the availability of a meter advance), to ensure that generators are not settled on zeroes inappropriately.
