IREG Update January 2021

IREG met on the 13th January 2021 and discussed the following MRA Issue Forms (MIFs) and Electricity Central Online Enquiry Service (ECOES) changes.

MIF 322 – ‘Automating Communications with the Secure Data Exchange Process (SDEP)’

IREG were updated that the draft design document had been returned by the SDEP Technical Service Provider (TSP) and would be shared with parties for review ahead of a technical workshop meeting which was currently scheduled for 27th January 2021. Industry parties would be informed as soon as arrangements were finalised.

Open SDEP MIFs and Issues Update:

MIF331 – ‘SDEP User Reporting’

IREG noted that the Impact Assessment was still with the Technical Service Provider (TSP) after Gemserv had provided them with further information. An update would be provided once the IA has been returned.

Implementation/Transition issues with the SDEP

IREG were informed that the log of issues was currently with the ECOES TSP for consideration and that an update would be provided once the IA had been returned.

MIF335 – MSN History Details available on ECOES

IREG noted that the MRA Executive Committee (MEC) and MRASCo Board had approved the funding for MIF335 and that the change would be incorporated in the February 2021 Release. IREG agreed to close MIF335.

MIF337 – ‘Inserting an Import/Export MPAN indicator in the ECOES API’

IREG were introduced to MIF337 which seeks to insert an import/export indicator into the ECOES API for clearer identification of the Meter Point Administration Number (MPAN) types.

IREG discussed a two -part solution, agreeing that a Change Request should be raised to address part one – to insert the indicator in the ECOES API to address the first part under the MRA. IREG recommended that part two – to update the MPAS/ECOES interface to include the Data Item held in MPAS into the Data Flow to replace the derived indicator in the GUI and API, should be addressed after Central Switching Service (CSS) go-live under the Retail Energy Code (REC). IREG agreed to close MIF337.

MIF338 – ‘Related MPAN Definition’

IREG discussed MIF338 which was raised following discussions held at the Data Working Group (DWG), where parties reported being unclear on the existing method for identifying if MPANs are related or not.

IREG discussed the options for making the Related MPAN guidance clearer for industry to follow, noting that an existing guidance document produced by Energy UK, should be reviewed by the DWG as an interim measure and until the guidance currently under consultation for the REC could be shared. It was noted that the DWG would be updated on the IREG discussions at its January 2021 meeting, and that a further update on the outcomes would be provided to IREG at its February 2021 meeting.

SPF109 – New BSC Data Flow for P375 

IREG reviewed SPF109 which seeks to introduce a new DTC Data Flow for the Half Hourly Data Collectors (HHDC) to send to Settlement Volume Allocation Agent (SVAA) to be used in Settlement. It was noted that the new Data Flows would not impact Suppliers or Distributers, as the Data Flows were only being re-purposed for HH and Meter Operation, however there could be some impact for Meter Operators (MOPs).

IREG noted the update and acknowledged that the next steps would be for the MRA Development Board (MDB) to discuss the proposal further and for the P375 Expert Group to report back to IREG if a future solution were required for development.

The next IREG meeting will take place on Wednesday 10th February 2021.


IREG Update October 2020

IREG met on the 14th October 2020 and discussed the following MRA Issue Forms (MIFs) and Electricity Central Online Enquiry Service (ECOES) changes.

MIF332 – ‘Changes to Message Ownership in Secure Data Exchange Portal (SDEP)’

IREG discussed MIF332 which proposes to add functionality to the SDEP to allow parties to bulk assign messages and to filter messages either by assigned/unassigned and read/unread. IREG were satisfied that the proposed solution addressed the issue provided and agreed for a request to be made to the MRA Executive Committee (MEC) for the approval of funding.

MIF331 – SDEP User Reporting

IREG were presented with the feedback and examples received from Parties regarding the SDEP User reports, where the current SDEP reporting could provide the outcomes requested by parties.

Gemserv advised that having multiple different bespoke reports within the SDEP would be costly however, parties would first need to identify the defects to be addressed in the reports before new or bespoke reports can be created.

Gemserv agreed to investigate the filter requirements for each of the reports and to provide a further update at the November 2020 IREG meeting.

MIF 322 – Automating Communications with the Secure Data Exchange Process (SDEP)

Gemserv advised that the second iteration of the Impact Assessment (IA) had been received from the ECOES Technical Service Provider (TSP) too late for IREG’s consideration at the meeting, but noted that the IA would still be presented to MEC for approval at its meeting on 27th October 2020.

MIF333 ‘New Meter Type (J0483) values to identify Auxiliary Proportional Controllers (APC)’ and MIF334 ‘Identifying Additional Electricity Smart Meters (ESME) and Standalone Auxiliary Proportional Controllers (SAPCs)

IREG reviewed MIF333, which seeks to identify if a change is required to the Meter Type Data Item J0483 in the Data Transfer Catalogue (DTC), to align with the Smart Metering Equipment Technical Specifications second generation (SMETS2) changes being implemented into the Smart Energy Code (SEC) Schedule 9 in November 2020. The SMETS2 functionality is being amended to incorporate Auxiliary Proportional Controllers (APC’s) in order to enable more precision and flexibility in the control of load. As a result, possible consequential changes are required to minimise data quality impacts for Suppliers and MOPs.

IREG also discussed MIF334 which addresses the Change of Supplier (CoS) process for the additional meters and APC’s to ensure settlement integrity is not compromised by Suppliers incorrectly matching ESMEs to incorrect meters.

IREG reviewed the proposed solutions for both MIFs and agreed that they should be combined and progressed as one MIF. IREG agreed to address all solutions under MIF334 and that MIF333 would be closed.

MIF320 – Review of the Unallocated Transactions Process

IREG discussed the proposed amendments to be made to MAP14 in order to improve the Unallocated Transaction process. IREG noted the amendments are an initial step in the performance assurance process and that MEC were committed to improving the Unallocated Transaction process prior to migrating to the Retail Energy Code (REC).

MIF335 – MSN History Details available on ECOES

IREG were provided with an overview of the MIF, noting that a request to include the full history of MSN details to be added to ECOES had been made. IREG discussed the proposed solution and put forward suggestions for the ECOES Technical Service Provider (TSP) to include in the Impact Assessment phase. A further update would be provided at the November 2020 IREG meeting.

ECOES User Requirement Specification (URS)

IREG reviewed the updates made to the ECOES URS ahead of November 2020 Release. IREG had no further comments and approved the ECOES URS.

ECOES Data Permissions Review


The MRA Executive Committee requested that IREG conduct a review of the data permissions available to each ECOES User Type. Gemserv provided an overview of each User Type and the suggested amendments to each category inviting IREG members to comment. IREG members agreed to provide feedback regarding PCW data permissions ahead of the November 2020 IREG meeting.

MIF336 – Secure Data Exchange Portal (SDEP) Central Switching Service (CSS) Data Cleansing Use Case

IREG reviewed MIF336 and were supportive of the proposed solution to create a specific Data Cleanse Use Case. Gemserv advised that an Impact Assessment would be sought from the ECOES TSP and that a paper requesting its approval would be taken to MEC at its October 2020 meeting.

The next IREG meeting will take place on Wednesday 11th November 2020.
