IREG Update: May 2018

IREG met on 9th May 2018 and discussed the following MRA Issue Forms (MIFs):

MIF219 – Full Review of Working Practice Product Set

IREG deferred the paper until its June 2018 meeting.

MIF248 – Plot Addresses

IREG agreed the reporting on Plot Addresses that will be sent to Ofgem. It also considered three changes to MRA Agreed Procedure (MAP) 09 (Address maintenance using the Standard Address Format), recommending that a single Change Proposal be taken forward.

MIF258 – Near Time Improvements to Electricity Meter Technical Details

IREG considered the Request for Information (RFI). It noted that some additional responses not provided with the published papers have now been included due to an extension to the RFI deadline for some responders. It noted the wide variety of responses, including those which are not Meter Technical Detail (MTD) related. It welcomed that the Meter Timeswitch Classes (MTCs) are validated when received. However, it noted issues with discrepancies between the MTDs and Electricity Central Online Enquiry Service (ECOES). It was agreed that, considering the potential volumes of work, the Faster Switching Workgroup should consider the RFI responses in more detail and prioritise the areas of activity based on future value.

IREG considered some initial analysis of MTC data, which indicated significant amounts of erroneous data. IREG agreed to consider what ‘pots’ were a priority to resolve and agreed that a report should be requested that identifies all non-address data so that these pots can be assessed at Supplier/MOP/Distribution level.

MIF261 – D0312 Process – Quick wins to aid MAP14

IREG considered MIF261, which seeks to bring down the number of unallocated monies owed associated with prepayment meters. It identified that further analysis of ECOES D0312 (Notification of Meter Information to ECOES) data flow validation functionality was required before any solution could be identified. Additional data to be provided on the Supplier-side D0312 rejections report was agreed to be progressed.

MIF262 – D0312 ECOES E2E Review

IREG agreed with the Proposer to postpone this MIF to the Faster Switching Workgroup, so it can be considered in the context of future requirements. As part of this review IREG noted that there will be a need to understand the validation process and perform a data comparison.

DTC CP3528 – Interoperability in the sub 100kW Half Hourly Market Post P272

IREG provided comments on the Data Transfer Catalogue (DTC) change, which the MRA Development Board (MDB) had asked it to look at. The Proposer agreed to make further changes and to bring the updated CP back to the June IREG.


IREG approved the ECOES User Requirement Specification (URS) with two minor amendments. Additional changes will be required subject to any changes identified to the D0312 data flow resulting from MIF261 and MIF262.
