IREG Update December 2019

IREG met on the 11th December 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 on the progress of the review. IREG noted the further analysis carried out on the remaining Working Practices and agreed to continue the review. IREG was presented with two draft Change Proposals (CPs), one for the removal of WP124 from the WPPS and a subsequent CP to move the guidance contained within WP124 in to MRA Agreed Procedure (MAP) 14. IREG approved the draft of the CP for the removal of WP124 from the WPPS and agreed that further work was required on the CP to add the guidance to MAP14. IREG agreed that Gemserv would draft a CP for the removal of WP145 and present to the group at the January 2020 meeting.

MIF288 – Industry Contacts Database

IREG was advised that the MRASCo website TSP was currently working on updating the Industry Contacts Database in User Acceptance Testing (UAT). IREG noted that there had been a slight delay with the progress of the upgrade. Gemserv had received a reasonable proportion of contact spreadsheets from parties which has been collated on a single spreadsheet and arrangements are being made for the data to be updated on the current Live environment in order to be converted into the new database.

MIF301 – Post Implementation Review of the DTC CP 3554

IREG noted the responses to the Request for Information (RFI) which was issued to parties following the October 2019 meeting. IREG discussed the next steps for the issue and potential solutions with members highlighting that the main problems lay with understanding how Meter Point Administration Service (MPAS) was processing the information. The group discussed potential ways in which data could be corrected using a Data Flow rather than the current manual system. The group discussed the MAP04 linkages and agreed that the MIF and the RFI responses would be presented at the next MPRS Service Management Group (SMG) meeting.

MIF306 – MAP08 – Missing/Disputed Read Process Issues

IREG noted the responses to the RFI. The Proposer advised that most of the responses highlighted the same sort of issues with the process that had been listed in the MIF and been discussed at the November 2019 IREG meeting. IREG agreed that a training session as opposed to a change to MAP08 would be the best way to resolve the issues. It was agreed that a training session for parties would be developed, with two parties agreeing to support the development of the training session. A party noted that the training session should be recorded so parties could access on demand. Gemserv advised that a request would need to be taken to the MRASCo Executive Committee to approve the training. The group agreed that a paper would be taken to the January 2020 MEC meeting seeking approval.

MIF 307 – Incorrect Designation for Domestic Elective Half Hourly MPANs in ECOES

The Proposer advised IREG that they had identified an issue whereby Domestic MPANs with Measurement Class F, a domestic indicator, and Profile Class 00 are being designated as Industrial and Commercial on ECOES incorrectly due to the historic association between Half-Hourly (HH) settlement and business energy supplies. It was advised that this was likely to cause more confusion due to the Market-wide shift toward more domestic half-hourly settlement.

The group discussed the issue and agreed this could cause problems in switching particularly with Third Party Intermediaries (TPIs) enacting switches as they would likely use the indicator in ECOES as opposed to the data. The group discussed potential solutions, such as removing the indicator all together from ECOES and amending the back-end data which populates the indicator field in ECOES. It was agreed that Gemserv would contact the ECOES Technical Service Provider (TSP) to identify how the indicator was populated and circulate this information to the group as soon as possible. Gemserv agreed to present a paper at the January 2020 meeting advising on potential solutions.

MIF308 – Prepayment Clearance Volumes

The Proposer advised IREG that they wished to conduct a review of the changes to the D0312 Data Flow processing which took place in June 2019 and assess the impact on the volume of unallocated prepayment transactions. IREG discussed the issue and agreed that the total of unallocated transactions was having a negative impact on the Customer, particularly those prepayment Customers.

The group discussed the way in which information was available to Suppliers prior to the June 2019 change. It was advised that the information had been available centrally in ECOES. Now the information was only available through Data Flows. IREG discussed how to resolve the issue and it was agreed that comparative data would be required to see the impact of the June 2019 change. It was suggested that data could be gathered from ElectraLink however, that would come at a cost. The specific data that would be required to identify whether there had been an increase in unallocated transactions since June 2019 because of the move to MPAS processing the D0312 Data Flow. It was agreed that the unallocated transaction report that is presented to the MRASCo Development Board (MDB) would be reviewed to identify if there was a change. The Proposer added that Gemserv should look for both a rise in the total of unallocated transactions and a reduction in clearance rates.

MIF309 – Related MPAN Objection

The Proposer advised that Ofgem via the Data Working Group (DWG) had set targets to cleanse related MPANs by 26th October 2020 however, this could not be achieved if Suppliers continued to split MPANs. The group discussed reasons for MPANs continuing to be split and discussed the Objections process. It was agreed that there was not an issue with the objections process itself rather Suppliers were not following the process correctly. The group discussed potential solutions and how the MRA could resolve the issue. IREG agreed to progress with a solution Gemserv would investigate what powers the MRA have to govern parties on this issue and potentially send a communication to parties that were continuing to split MPANs advising of the issues caused by this. It was agreed that the MIF would also be raised at the next DWG meeting.

Safe Guarding Working Group Update

IREG was advised that the needs codes changes have now been agreed for implementation through relevant governance groups (MDB/SPAA) and will go live from February 2020 to support a maturity of thinking and adapt to the needs of the water sector. It was highlighted that water companies and Distribution Businesses were sharing data manually in some cases in preparation for go live. IREG were advised that water companies had been tested Data Flows with a Distribution Business.

IREG noted that there had been a lot of work to progress the DPIA which is now with companies and working group members for review. I was advised that there had been discussions amongst a small number of companies about exploring SPI as a legal basis for sharing data (as opposed to explicit consent) but these are early conversations and certainly won’t impact the project.

There is a joint task and finish group, created to produce a single manual detailing a standardised approach to data sharing based upon the current mechanism. This document will act to pull together all of the governance and support details that are already available, creating a one stop shop – but importantly it will have links to relevant parties’ external pages, to ensure that future revisions are automatically available. The group were advised that all companies involved were still committed to April 2020 go live.

Secure Data Exchange Portal (SDEP)

IREG noted the first draft of the SDEP User Requirement Specification (URS). The group were advised that Gemserv were not seeking approval on the draft until the conclusion of User Acceptance Testing (UAT) in May 2020. It was highlighted that the document would be brought back to IREG for review prior to this to ensure that Gemserv deliver the document correctly and is fit for purpose for all parties. It was clarified that the SDEP URS would be a standalone document and would not link to the ECOES URS. The group discussed the file size upload limit, it was highlighted that this information was still to be confirmed and an update would be available to IREG at the next meeting. It was advised that .zip files could be sent through the system as an attachment much the same as an email. The Chair advised that parties could send comments ex committee to Gemserv via an email to or
