Topic Detail Review of HWG minutes

Minutes of HWG from 6th April were reviewed.

Review of DRs and MCRs from HWG

The HSG approved, the following MCRs: MCR 1051: New 017 Meter point Status Reason – Re-energise (rewire) MCR 1052: Keypad Meter CoS Process – Removal of old keypad Reference Number on 105L and 110 Market Messages MCR 1053: Fieldwork Cancellation on CoS MCR 1058: Meter Works type Code, Access Arrangements – CoS

The HSG also approved MCR 1054 (Removal of Supplier certification checks during MM validation) in principle. This MCR would see the removal of supplier certification checks being carried out within the market systems – aligning with the scenario in the Republic of Ireland. In their place, broader checks will be conducted. The nature and extent of these broader checks are to be confirmed to the Utility Regulator by NIE.

The HSG was informed that the following three MCRs were jurisdiction specific and were being progressed through the SIG. MCR 1060: Removal of Fieldwork Notice Periods MCR: 1061: De-energisation Requests by Old Suppliers during CoS MCR 1063: EUF Calculation for Re-energised Sites The HSG was informed that the following DRs are still in progress and will be discussed at the next HWG on 18th May. DR 1055: New register types, time of Use Codes and MCC Codes (H) DR 1056: Removal of Fields from NI Market Website (N) DR 1057: Removal of Usage type (including MCC / DUoS group) on CoS Message (H) DR 1059: Removal of Implied Energisation from 030 (N0 DR 1062: Removal of DUoS tariff T051 (H) DR 1065: Removal of Implied Change of Usage from 030 (N)

MCR1055 v2- New Register Types, Time of Use Codes and MCC Codes

Change Request Register Types/Timeslot Codes

To more accurately define the types of registers and the time periods for measuring consumption that exist within the NI Market and to support the MCC codes that are proposed for the ESP

MCC Codes To rationalise the set of MCC codes that will be available to

Suppliers so that where possible a single MCC code will describe a unique register configuration. The proposed set of MCC codes will support the tariffs that will be available to Suppliers in the Enduring Solution and will reflect the Register Types and the time periods for measuring consumption that exist in the NI market

Harmonisation Impacting change request No change since DR
