Formal title: Clarification on the MAR tolerance calculation
BSCP502 section 4. 7 requires that the HHDC Agent performs the Meter Advance Reconciliation to ensure that the Half Hourly data taken into Settlements sums to the meter advance read on site from the prime registers for the same interval “within a tolerance of 0. 1%”. It has been observed previously during discussions with two of the HHDC Agents that they have applied a different interpretation of the tolerance indicated in BSCP502. The current wording of BSCP502 is sufficiently ambiguous to allow either interpretation.
