IREG Update September 2019

IREG met on the 11th September 2019 and discussed the following MRA Issue Forms (MIFs) and Electricity Central Online Enquiry Service (ECOES) changes.

MIF219 – Full review of the Working Practice Product Set (WPPS)

IREG received an update of the progress of the review. IREG noted the further analysis carried out on the remaining Working Practices and agreed to continue the review. It noted that there were still Working Practices (WPs) that could be removed from the WPPS due to redundancy. As such it agreed that the drafted Change Proposal (CP) to remove WP76 could be progressed to MDB.

MIF281 – Crossed Meters

The ECOES TSP presented a revised overview of the ECOES element of the Crossed Meter solution process having considered comments made from the previous meeting’s presentation. IREG discussed whether cases should be closed when ECOES has been updated with the meter details or when settlement is corrected. One party questioned the benefit of using another system especially when this may differ to gas, however, IREG noted that Ofgem are keen to see a solution in place as it is currently mandated within the SPAA and therefore a step to delivering what will be required under the REC.IREG felt the concerns from the previous meetings presentation had been addressed by the TSP and the suggested technical amendments had been incorporated into the design. IREG were presented with the draft Crossed Meters MAP which was amended further after a workshop review. IREG walked through the redlined changes and updated the details of the updated version to agree a final draft to be taken forward. IREG agreed that the CP to introduce the new MRA Agreed Procedure for Crossed Meters could now be drafted and submitted into the change process and be presented at September’s MDB (MRA Development Board).

MIF283 – ECOES Upload to Distribution Third Party Systems

IREG were informed that the additional development work for the ECOES enhancement was due to go live in November. IREG agreed for the MIF to be closed.

MIF288 – Industry Contacts Database

IREG was informed that the upgrade to the MRASCo Industry Contacts Database was still in the User Acceptance Testing (UAT) phase. Parties were again encouraged to take part in UAT with one party agreeing to take part. A few issues had been identified which had been raised with the TSP with most issues already rectified. IREG noted that Parties had also been contacted to ensure data for the database was accurate.

MIF294 – Suppliers can require New Connection registrations, without a Meter installed, to be cancelled

The Proposer advised that the draft amendments to the BSCP’s were now with the British Gas SVG representative.  The proposer confirmed that this MIF could be parked until November when a status update was next expected.

MIF296 – Review of the Non-Domestic Customer Access to ECOES

IREG noted the papers provided. IREG discussed the fact that there are potentially some issues with the process that needed to be investigated such as what happens, when a customer within the NDC portfolio changes and not part of their portfolio, when a customer within the portfolio sells off some of that portfolio, how are those MPANs within the portfolio taken out. IREG further noted that consideration needs to be assessed regarding the access principles along with whether those companies should be included within the annual audit process. IREG agreed that this was a security issue that should be considered first at the MSC October 2019 meeting.

MIF301 – Post Implementation review of the DTC CP 3554

IREG discussed issues relating to the recently implemented changes to the D0312 Dataflow processing. These included problems validating MAP ID’s and updating historical records. IREG continued to focus on the rules that were in place to correct all D0312 related issues advising that previously these could be manually corrected in ECOES and now actions can only be fixed by issuing new D0312 Data Flows and updating their own systems. IREG discussed the need of having a guidance document to aid parties with issues that arise. IREG noted that the reject codes are set  out in the MPRS Validation Rules but do not give enough understanding as to how the validation is and what specifically is being validated as the codes are “short codes”, therefore it would be helpful to try and understanding the detail of those rules for the D0312 and D0304. This would could then either be updated in the MPRS Validation Rules or a separate guidance document could be created.

Parties were encouraged to send issue examples to understand the various scenarios that are occurring so that they can be collated for the next meeting.

MIF302 – Ceasing the Related Meter range of MTCs

The Proposer highlighted that the issue had been raised following the implementation of the new “Related MPAN Indicator (J2245) and changes to MPAS Processing for CSS. The Proposer advised that it was an opportunity to look at the option of removing the related ranges of MTCs from the MDD. The Proposer noted that they felt there were 3 options; 1) Do nothing; 2) Rationalise the range of MTCs or Remove Related MTCs from the MDD. A party noted there was a 4th option removing of the MTC’s as they were not required for billing purposes. Another party confirmed DNO’s require the MTC to map the LLFC to the SSC to ensure the correct tariff is being used and billing of DUOs charges. IREG agreed that plenty of work was required to understand the severity of the issue and whether it was too early to unpick the details at this moment in time. Other opportunities may be better timing to consider the use of MTCs such as when the Radio Tele-switches are removed or revisiting consequentially to the Smart metering roll out and the market wide Half Hourly Settlement as part of targeted review further down the line. IREG agreed the MIF should be closed.

Secure Communications

IREG were presented with an updated draft MAP and were asked for comment on the latest version. The new MAP is setting out the rules of the use of the new service. It was agreed that comments on the MAP and Access Agreement should be sent to the IREG mailbox by 20th September 2019. IREG recommended the Proper to postpone submitting the related MAP CP until the Access Agreement had been legally reviewed in case any consequential changes are needed as a result of that review. One party queried whether the related Use Cases would be incorporated into the MAP. An advisor confirmed the Use Cases will go into the URS and individual MAPS. IREG agreed the updates to the IREG ToR were sufficient and were happy for them to be presented to MDB for final approval.

Safeguarding Customer Working Group

IREG were advised that there was no new progress since there had been no meeting since the last IREG, however everything was still on track as last reported. The only significant update of note was that Utility Weekly Magazine had written a related article but there was no planned date of publication. The Energy and Water companies have requested site of the finished article before it is published. IREG were also informed SPAA voted on the related changes to the PSR codes and this was expected to align with the MRA change due for implementation in February 2020.


IREG were advised that minor changes had been made to the URS but nothing material was changing. Changes to clause 15.2 are due to be discussed by FSEG so IREG agreed the final version of the change would be brought back to IREG next time. IREG agreed the other two additional minor changes should be approved.


The next meeting is scheduled for Wednesday 9th October
