CP1188 – Improvements to the use of the Half Hourly Aggregation Exception Report (D0235)

Formal title: Improvements to the use of the Half Hourly Aggregation Exception Report (D0235)

Summary

Currently if a SVA metering system is de-energised a Half Hourly Aggregation Exception Report (D0235) is generated if non-zero consumption value is provided to the Half Hourly Data Aggregator (HHDA) by the Half Hourly Data Collector (HHDC). If the Metering System is de-energised by the Half Hourly Meter Operator (HHMOA) at a time later than 00: 00 hrs it is likely that a non-zero value will be recorded by the HHDC on the effective from date of the de-energisation.   This will cause an exception report (D0235) that the Supplier will never be able to resolve. CP1188 proposes that non-zero values recorded on the effective from date of an energisation status change, from energised to de-energised, should not be reported as an anomaly to the HHDC and Supplier.
