IREG Update September 2018

IREG met on 12th September 2018 and discussed the following MRA Issue Forms (MIFs) and Electricity Central Online Enquiry Service (ECOES) changes:

MIF219 – Full review of Working Practice Product Set

IREG:

  • Noted that the MRA Development Board (MDB) rejected WPPS CP 150 (Delete WP77 from WPPS). The rejection came about when one Distribution Business (DB) rejected the change, one supported it and the other DBs were neutral or had no interest. The DB that rejected it as there were no corresponding DTC CP to add clarity in the Data Transfer Catalogue (DTC). A Proposer will be raising a DTC CP to address this and a new WPPS CP to remove WP77.
  • Agreed to progress CPs for WP6 (Determining the Meter Reading on Change of Supplier (MRoCoS)); WP104 (Population of D0086 for Non-Settlement Registers); WP119 (Change of Supplier with shortened registration); WP152 (Requesting Additional or New MPANs).
  • Agreed to the review of WP 57 (Error Handling – Notification); WP 58 (Error Handling – Whole File Retransmission); and WP 59 (Error Handling – Correction of Errors).

MIF258 – Near Time Improvements to Electricity Meter Technical Details

IREG supplied feedback on the draft reports issued to it. The group agreed amendments required to enable the reports to be re-issued along with documenting how the design of the reports were developed. IREG agreed to transfer this MIF to the Faster Switching Expert Group (FSEG) for future management of the activities.

MIF261 – D0312 Reports

IREG noted that the FSEG is drafting changes, that if approved, would remove the D0312 (Notification of Meter Information to ECOES) Data Flow. Instead, ECOES will receive the metering information from Meter Point Administration Services (MPASs) in the future. IREG noted that the rescoping of the reporting under the MIF would better sit under the FSEG work as the data cleansing of ECOES is for the benefit of the Ofgem Switching Programme. IREG agreed to transfer this MIF to the FSEG.

MIF264 – DTC Annex C – D0148 Section – 10 scenarios not explicitly covered

IREG noted that the Proposer of the MIF is unable to attend to discuss or progress this MIF. Although there are no formal processes for adoption of MIFs, IREG agreed to share the MIF on Huddle with a message seeking a new Proposer. Should no new Proposer be found ahead of the MRA Development Board on 27th September 2018, then the MIF will be closed.

MIF271 – Managing ECOES User Access

IREG considered the estimated costs of implementing the changes and agreed that the ECOES User Requirement Specification (URS) changes should be reviewed and agreed at its October meeting.

MIF272 – Meter Serial Number not known on CoS for Smart DCC-serviced meters

IREG noted the three responses received for the request for information (RFI) and supplied feedback on the draft changes. The Proposer will take forward a DTC CP that considers the feedback provided.

MIF273 – Additions to section 4 (Access to ECOES) of MAP15

IREG agreed with the proposed solution to include additional parties to MAP15. A Party agreed to Sponsor a MAP CP to take forward the solution.

MIF274 – Improve the Electricity Online Enquiry Service (ECOES) User Administration

IREG supplied feedback on the solution and considered the initial estimated costs of implementing the changes. It agreed to the proposals to improve the reporting. However, it wanted to seek feedback from the ECOES Master Administration Users (MAUs) and parties on which functions they would like to be able to give to others within their businesses.

MIF276 – ECOES Letter Privileges

IREG supplied feedback on the solutions and agreed to consider the ECOES URS changes at its October meeting.

MIF275 – Process to support an Authority decision when provisional order issued

IREG agreed with the proposed solution and recommended that the Proposer raise as a material MRA CP so that the Authority approves the CP. The Proposer will look to progress an MRA CP for the October’s MDB.

MIF277 – MS Access version of DTC

IREG noted that any change to version of the MS Access database used for the DTC is under the MRA Executive Committee’s (MEC) vires. It therefore recommended that a request is raised to MEC for it to consider upgrading to a version that Microsoft supports. The outcomes from MEC to IREG will be confirmed.

MIF278 – Gap with HH Change of Meter Operator process

Within the D0268 (Half Hourly Meter Technical Details) Data Flow, the Manufacturers Make and Type is optional. However, it is mandatory on the subsequent D0303 (Notification of Meter Operator (MOP), Supplier and Metering Assets installed / removed by the MOP to the MAP). IREG noted that in the D0150 (Non Half-hourly Meter Technical Details) Data Flow, the Data Item is mandatory. Annex C of the DTC, rule 5 states: “Manufacturers Make & Type optional as Outstation Type is coded.” IREG agreed to seek the Association of Meter Operators (AMO) views of whether the Data Item should be made mandatory.

ECOES testing approach for MAP CP 0298 and ECOES API

IREG supplied feedback on the testing approach for the two ECOES changes. IREG noted that, although it has agreed the ECOES specifications to support MAP CP 0298, it has not yet agreed the ECOES URS changes. As such, it will consider these at its October meeting.

Next meeting

The next meeting is scheduled for Wednesday 10th October.

IREG Update: August 2018

IREG met on 8th August 2018 and discussed the following MRA Issue Forms (MIFs):

MIF219 – Full Review of Working Practice Product Set

IREG deferred further discussions on this MIF to the next meeting.

MIF248 – Delays with Plot Addresses being updated

IREG agreed the Plot Address progress report for Ofgem and to seek feedback from them on the reports.

MIF258 – Near Time Improvements to Electricity Meter Technical Details (MTD)

IREG noted that the MRASCo Board had approved funding for MTD comparison reports. IREG provided feedback on the draft high-level guidance to be issued with the reports. The guidance will be finalised ex-committee.

MIF263 – Impact of Data Communications Company (DCC) Enrolment and Adoption on Register Mapping

The Proposer confirmed that they will close the MIF and progress a Change Proposal (CP) to the MRA Development Board (MDB).

MIF264 – DTC Annex C – D0148 Section – 10 scenarios in which a D0148 is necessary are not explicitly covered

IREG noted that the Proposer was unable to attend or send a representative to the IREG meeting and agreed to defer further discussions on this MIF to the next meeting.

MIF269 – Impact of SECMP0006

IREG gave comments on the draft Solution Pre-Assessment Form (SPF) which the Proposer had developed following initial discussions at the July meeting. They highlighted that ELEXON had suggested a third option to be included. All three options will be included in the updated SPF, which will also be issued via ELEXON to BSCCo change contacts.

MIF271 – ECOES User Management

IREG agreed to develop the following changes to Electricity Central Online Enquiry Service (ECOES) User Management:

  • For Solution 1, IREG supported option 1b of the MIF where the password reset function will be expanded to include ability to delete accounts. IREG agreed to seek costs from the Technical Service Provider.
  • For Solution 2, IREG agreed to take forward changes to the way password resets are done within ECOES. Under this option, Users who have their email as their username, any password reset is done by sending a reset link to their email address. This assumes that when an employee leaves a company their access to their email is revoked stopping them being able to complete a password reset process.

IREG noted a new MIF will be raised regarding the administration maintenance and agreed to seek costs ahead of the initial review.

MIF272 – Meter Serial Number not known on CoS for Smart DCC-serviced meters

IREG carried out an initial review of the MIF and agreed to issue a request for information (RFI) on:

  • sourcing of the Meter Serial Number (MSN) in the absence of the MTDs; and
  • actions taken when the MSN has a mismatch with the MTDs when received.

ECOES User Requirements Specification (URS)

IREG approved the changes to the URS for D0312 (Notification of Meter Information to ECOES) Data Flow reports, and to seek costs for the development. Following discussion and clarification on a few points for the Application Interface Solution (API) an updated document will be issued ex-committee for approval. The timetable for testing will be presented to the September IREG meeting for approval.

ECOES testing approach associated to MAP CP 0298

IREG agreed the test approach and criteria for the implementation of the ECOES solution associated with approved MRA Agreed Procedure (MAP) CP 0298 (Request for Additional Import / Export MPANs using ECOES2). A more detailed plan will be provided at the September IREG meeting.

MAP CP 0299 and MAP CP 0300 review

IREG considered the MAP CPs 0299 (Change to include D0171 and D0131 into process steps) and 0300 (Population rules for plot addresses) redlined changes to MAP09 (Address maintenance using the Standard Address Format). This followed referral from MDB. IREG proposed additional changes to ensure clarity was added into the process to address the comments received via the Impact Assessment. With these addressed and the Proposer agreeing to the changes, the CPs will be sent back to MDB for its decision.

Post implementation review of DTC CP 3508 and MAP CP 0283

IREG reviewed the RFI responses in respect the new processes implemented under two change proposals. IREG noted that clarity could be provided in Annex C of the Data Transfer Catalogue (DTC). This would ensure it is clear it is the Supplier’s contact details and not the Customer ones’ that should be provided in the D0381 (Meter Point Address Update) Data Flow. A Proposer was found to raise a DTC CP to progress the change. IREG identified no further actions and the review was closed.

IREG Update: July 2018

IREG met on 11th July 2018 and discussed the following MRA Issue Forms (MIFs):

MIF219 – Full Review of Working Practice Product Set

IREG agreed that all the Change Proposals (CPs) that had been proposed should be submitted, on condition that minor updates, identified during the meeting, have been incorporated. These CPs covered:

Working Practice (WP) 21 – Provision of Metering Point Changes to Agents;
WP 77 – Identification of New Agent on flow D0170;
WP 100 – Termination/Cancellation Dates on Agents appointment;
WP 34 – Termination of New Supplier Agents during the Objection Process; and
WP 33 – Providing Customer Details to the Distributor during Registration.

The next Working Practices to be reviewed are:

WP 9 – Related Metering Points;
WP104 – Population of D0086 for Non-Settlement Registers; and
WP119 – Change of Supplier with shortened registration.

IREG agreed to consider the prioritisation of the Working Practices still to be reviewed in more detail at the next IREG meeting in August 2018, in light of the proximity of the Retail Energy Code.

MIF248 – Plot Addresses

IREG were notified that the report had been re-run and the new instances are due to be issued to Parties by 13th July 2018. Analysis can be done and information fed back to the IREG Secretary by 31st July 2018 to be included in the progress report to Ofgem, which will be issued at the beginning of August 2018. IREG requested that a count of new Meter Point Administration Numbers (MPANs) be provided.

MIF258 – Near Time Improvements to Electricity Meter Technical Details (MTD)

It was noted that the request for funding for MTD comparison reports and improvements to D0312 reporting was due to be sent to MRASCo Board imminently. High level guidance will be prepared for parties if funding is approved, and once confirmation of the delivery timescales are known, will be sent to IREG members.

MIF259 – Update Contact Types and their mandatory status

IREG identified the action to amend each contact type following review of the responses to the Request for Information. Some contact types will be removed, some will be updated to Mandatory or Optional and some changes will be progressed to the MRA products. There will also be functionality updates requested to Industry Contacts Database.

MIF263 – Impact of Data Communications Company (DCC) Enrolment and Adoption on Register Mapping

IREG discussed the proposed drafting for Annex C changes, following minor updates that were identified, this CP should be submitted to the MRA Development Board (MDB).

MIF268 – Improving the Faults process

ELEXON introduced this MIF which seeks to update MRA products in line with changes identified to the BSC Procedures (BSCPs) to improve the fault investigation process. IREG provided feedback on the suggested solution and requested that the BSCP changes were provided against the MRA changes to provide an assessment. It was agreed that the solution would be best implemented for Half Hourly first and then consideration could be given to whether it works for Non-Half Hourly (NHH).

MIF269 – Impact of SECMP0006

IREG discussed the impact of SECMP0006 which introduces rules for the number of digits that can be displayed on a meter. As the impact was not fully understood IREG recommended that the Proposer draft a Solution Pre-assessment Form, to allow all parties to consider and feedback on the potential impacts and options for solutions.

MIF270 – Creation of a Valid set for CT ratio and VT ratio

ELEXON presented this MIF which seeks to introduce a set of valid values to be used in the Data Items J0454 (CT Ratio) and J0455 (VT Ratio). Two options were suggested, a national level list and a list per Distributor Short Code. Questions were raised regarding private networks, who would access the data and who would be responsible for obtaining the ratios in certain scenarios. ELEXON agreed to consider the questions and draft a CP.

ECOES User Requirements Specification (URS)

IREG reviewed the changes to the URS and following discussions it was agreed that the changes would be re-written to be clearer and more consistent with the rest of the document.

DTC CP 3536 – Amendment to descriptions in the J0483 Data Item

This CP has been approved for implementation in November 2018 however an update is also required to Annex C, to keep it aligned with the data item changes. IREG recommended this CP is submitted for consideration by MDB in July 2018.

IREG Update: June 2018

IREG met on 13th June 2018 and discussed the following MRA Issue Forms (MIFs):

MIF219 – Full Review of Working Practice Product Set

IREG deferred further discussions on this MIF to the next meeting.

MIF258 – Near Time Improvements to Electricity Meter Technical Details (MTD)

IREG agreed the top three mismatches of MTD data to be investigated further. Once the data has been extracted from Electricity Central Online Enquiry Service (ECOES) this will be distributed to parties to do an impact assessment. Approval for the data to be extracted from ECOES will be sent to the MRASCo Board.

MIF259 – Update Contact Types and their mandatory status

IREG deferred further discussions on this MIF to the next meeting.

MIF261 – D0312 Process – Quick wins to aid MAP14

IREG reviewed the D0312 (Notification of Meter Information to ECOES) rejection code processing and considered the changes proposed to the ECOES User Requirements Specification (URS) aimed at improving the reporting and the descriptions of the rejection reasons for users. IREG agreed these should be progressed and to request the approval of funding.

MIF263 – Impact of Data Communications Company (DCC) Enrolment and Adoption on Register Mapping

IREG discussed MIF263, which seeks to clarify the register mapping requirements for Smart Metering Equipment Technical Specifications (SMETS) 1 meters. Data Transfer Catalogue (DTC) changes were introduced in 2017 for register mapping rules on DCC-serviced meters and it is unclear if these now apply to SMETS1 meters when they are enrolled. IREG recommended that proposed changes to the D0367 (Smart Meter Configuration Details) and/or Annex C be circulated for wider comment via a Solution Pre-Assessment Form.

MIF264 – DTC Annex C -D0148 Section – 10 scenarios in which a D0148 is necessary are not explicitly covered

IREG discussed a gap in the process for Change of Measurement Class (CoMC) when moving from or to elective Half Hourly settlement. IREG discussed the need for a Smart Change of Supplier (CoS) indicator, so agents would know what process to follow. The Proposer agreed to work with another Supplier representative to draft changes for IREG to review.

MIF265 – Incorrect Grid Supply Point (GSP) Group

MIF265 looks to prevent MPANs being given the wrong GSP group, and agree a standardised process for correction of errors. IREG agreed that corrections should fall under the MRA Agreed Procedure (MAP) 04 (Procedure for Error Resolution and Retrospective Manual Amendments) procedure, but that this should be supplemented with specific rules or guidance for this scenario. The Proposer agreed to draft some wording for IREG to review, with assistance from a DB representative.

MIF266 – Exempt Premise List (EPL) ECOES 2 change

IREG discussed the licence obligations for Suppliers to provide an EPL of premises where the meter cannot successfully be connected to any type of Home Area Network (HAN). The obligations are independent of the Alt HAN go-live decision and must be delivered in an efficient and cost-effective method. IREG advised that without the detailed requirements of the data and the process to maintain the EPL it could not determine if ECOES is the correct repository. IREG recommended that the proposer request that a working group under the SEC further develop the requirements and then IREG can assess if ECOES and/or Data Flows are the correct solution.

MIF267 – Alt HAN Inventory ECOES 2 change

IREG discussed the licence obligations for Suppliers to provide a database of Alt HAN equipment installed at premises. IREG agreed that this was similar to MIF266 and should be progressed alongside it.

Post implementation review of DTC CP 3508 (New Address Flow)

IREG requested that a Request for Information (RFI) be issued to understand any issues or difficulties that parties had encountered with the introduction of the new D0381 Data Flow and the process to use it, under MAP CP 0283 (Secure data transfers changes to MAP09). The RFI questions and timescales were agreed, so that the responses can be considered at the August IREG meeting.

ECOES Application Programming Interface (API) requirements

IREG were informed that MRASCo Board has requested that the ECOES API for MRA parties be implemented as soon as possible. User requirements were presented to IREG as a late paper and were agreed, noting that a csv format output would be wanted. The ECOES User Requirement Specification (URS) will be presented to IREG for approval based on the requirements agreed.

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.

ECOES2 URS

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.

Special IREG Update April 2018

IREG met on 18th April 2018 and discussed MIF248 – Delays with Plot Addresses being updated.

The group reviewed the output of the draft extracts and reports, that shows instances of addresses that exist in Electricity Central Online Enquiry Service (ECOES) containing ‘plot’, ‘PL’ and ‘PC’,. The report provides detailed information per Supplier and per Distribution Business. IREG agreed that the initial focus should be on instances of ‘plot’ only, as ‘PL’ and ‘PC’ exist in small volumes and will be more complex to cleanse. Some duplicate records had also been identified in the initial set of records and IREG were notified that these had been caused by multiple Meter Serial Numbers (MSN) existing on a Meter Point Administration Number (MPAN). IREG agreed that the report should be re-run to exclude the duplicates and to identify ‘plot’ instances only.

The totals from the re-run report will be utilised to send the base-line figures to Ofgem. Quarterly progress reporting will then be provided.

The draft process steps to be included in MRA Agreed Procedure (MAP) 09 (Standard Address Format and Guidance Notes for Address Maintenance) were reviewed. IREG recommended various changes and agreed that the updated drafting would be reviewed at the IREG meeting in May. A further addition to MAP09 was identified, to define how plot addresses should be held in the Metering Point Address fields. This will standardise how plot addresses are applied across parties and allow future identification of the instances to be easier.

A proposal for data cleanse comparison, from the Technical Service Provider, was considered but IREG confirmed that it was not required at this time.

IREG Update April 2018

IREG met on 11th April 2018 and discussed the following MRA Issue Forms (MIFs):

MIF219 – Full Review of Working Practice Product Set

IREG was presented with updates on the review of the Working Practices (WP) and agreed that:

  • WP 21 (Provision of Metering Point Changes to Agents) – some rules could be added to MRA Agreed Procedure (MAP) 09 (Address maintenance using the Standard Address Format) and then to remove the WP. When updating MAP09, to ensure a complete process is captured it agreed that the processes associated with the D0171 (Notification of Distributor Changes to Metering Point Details) and D0131 (Metering Point Address Details) are included.
  • WP77 (Identification of New Agent on flow D0170) –the rules for this are already captured in the Balancing and Settlement Code (BSC) Procedures therefore the WP could be removed.
  • WP100 (Termination/Cancellation Dates on Agent Appointment) – that the notes from the WP should be moved to Annex C of the Data Transfer Catalogue (DTC) and then remove the WP.
  • The next WPs for review should be:
    • WP9 (Related Metering Points)
    • WP33 (Providing Customer Details to the Distributor during Registration); and
    • WP34 (Termination of New Supplier Agents during the Objection Process).

It was highlighted that some WP are referred to in the MRA Agreed Procedures (MAPs). The references need to be addressed alongside the assessment of the WPs.

MIF238 – Changes to WP152 Requesting Additional or New MPANs

IREG reviewed the proposed changes to the Electricity Central Online Enquire Service (ECOES) and the Change Proposals (CPs) to take forward the solution identified under this MIF.

IREG noted that the D0168 (Request for Additional/New MPAN Core(s)) could still be sent out up to the implementation of the CPs and there will still be a need to respond with to D0169 (Allocation of New/Additional MPAN Core(s)). It therefore suggested the following implementation approach for the two the DTC CPs:

  • remove the D0168 flow in November 2018 to align with implementing the new process; and
  • remove the D0169 flow in February 2019 to allow for responses to the D0168 up to this date.

It was discussed that the changes will only be made against ECOES2 therefore removing the flows would require participants to have migrated to ECOES2 to be compliant with the MAP. IREG agreed to the need to review the new process six-months after implementation of the new MAP.

IREG noted the need to have the funding for the ECOES2 changes approved by the MRA Board. The CPs will be submitted to MRA Development Board (MDB) April 2018. A change to remove the WP152 (Requesting Additional or New MPANs) will be submitted if the current CP is accepted.

MIF252 – Use of D0135, D0126 and D0368 Flows in Gas First Only Scenarios

IREG noted that this issue was discussed at another industry workshop. The Proposer is waiting for the outputs of that workshop before the MIF can be progressed.

MIF253 – Adding Estimated Annual Consumption (EAC) to ECOES

The Proposer advised that they were awaiting an update on this issue from internal colleagues.

MIF255 – Raising NHH Export MPANs for Smart

IREG reviewed the CPs and draft redlining, identifying some final amendments. The Proposer intends to submit the CPs in time for discussion at MDB April 2018.

MIF257– Meter Serial Number not on DCC Inventory

IREG commented on the draft CPs and red-lining. The Proposer intends to submit the CPs in time for discussion at MDB April 2018. Due to the timescales and changes to introduce changes to the DTC that will require party system changes, the implementation date was recommended to be February 2019.

MIF258 – Near Time Improvements to Electricity Meter Technical Details

The Chair summarised the outcomes of the Special IREG held on 28th March 2018.

IREG noted that the MRA Security Committee (MSC) has recommended a privacy impact assessment (PIA) for a full comparison of data, subject to MRA Board approving the funding.

ECOES2 Update

IREG noted that testing phase 2 functionally has progressed and the functionality will shortly be made available to those migrated to ECOES2. It was noted that more communication is required on progress.

IREG noted that some additional comments on ECOES2 User Requirement Specification (URS) have been received after the Special IREG that walked through the changes. All comments will be addressed in a final version of the URS and circulated with a comments review sheet detailing how the comment has been addressed. It considered what process was required to approve the URS and agreed to put the ECOES URS on the May IREG agenda for final approval.

Special IREG March Update 2018

IREG met on 28th March 2018 and discussed the following:

MIF258 – Near Time Improvements to Electricity Meter Technical Details

IREG noted that MIF258 was raised following a request of the Ofgem Switching Programme and the MRA Executive Committee (MEC). The MIF seeks short-term improvements in Meter Technical Details (MTD) data quality by the end of 2018, as well as consideration of any longer term or preventative measures that could be introduced. Representatives from Ofgem, the Association of Meter Operators (AMO) and Meter Operators (MOP)s were present for the discussions.

The group discussed at length the scope of the reconciliation, what the definition of MTD was and what was achievable by the end of the year. Some potential quick win scenarios were agreed, where combinations of Data Items held in Electricity Central Online Enquiry Service (ECOES) would suggest an error or mismatch exists.

The D0312 (Notification of Meter Information to ECOES) Data Flow and its associated processes, including rejections was also discussed. Investigations by some members of IREG on some of the existing rejected D0312s had been inconclusive regarding the actual cause of the failure. Some more analysis was requested by IREG, on the rejection methodology in place for each of the eight rejection types.

It was agreed that a Request for Information (RFI) will be issued to obtain wider engagement on the Data Items validated ahead of a customer switch, the use of the MTC and how the D0132 processes are utilised. Some analysis will also be undertaken to identify if Parties and their Agents are using the D0132 functions available in ECOES.

Following debate on potential comparisons that could be done between data held in ECOES and that held by Suppliers and/or MOPs, an issue with access to the data sets to do the analysis and compliance with General Data Protection Regulations (GDPR) was highlighted. IREG agreed that this should be taken to the MRA Security Committee (MSC) for advice on the security and data protection implications of accessing data for the work required.

IREG Update March 2018

IREG met on 14th March 2018 and discussed the following MRA Issue Forms (MIFs):

MIF219 – Full Review of Working Practice Product Set

IREG deferred the paper until its April 2018 meeting.

MIF238 – Changes to WP152 Requesting Additional or New MPANs

IREG walked through the updated solution proposal for changes to the Electricity Central Online Enquiry Service (ECOES) to address comments received at the previous IREG walkthrough. Additional adjustments were identified. The Proposer agreed to raise these with the Technical Service Provider (TSP). Once the requirements have been finalised a quote will be obtained for approval of central funding. Further work will also be required to develop a MRA Agreed Procedure (MAP), incorporating the new ECOES functionality.

MIF243 – Adding Supplier as recipient of D0005 Data Flow

The Proposer advised IREG that this MIF was still on hold, pending a new MIF which will supersede it to review the fault process.

MIF248 – Plot Addresses

IREG noted that the MRA Executive Committee (MEC) had approved the ECOES reporting, along with the provision of the underlying scripts to parties. Another Special IREG will meet to consider the outputs and other actions associated with the MIF.

MIF253 – Adding Estimated Annual Consumption (EAC) to ECOES

This issue seeks to improve customer switching and calculation of consumer costs, and looking to align with the gas change already implemented to have the Annual Quantity (AQ) available. The Proposer advised IREG that they are still to consider IREGs comments from February’s meeting. IREG were advised that although the EAC may not exist after 2020, that this MIF might raise a short-term change, or the MIF might be withdrawn. The Proposer advised IREG that an update will be provided at April’s IREG meeting.

MIF255 – Raising NHH Export MPANs for Smart

This issue looks to implement defined response times for Distribution Businesses to respond to following a request for a new Non-Half-Hourly (NHH) Export Meter Point Access Number (MPAN). A higher volume of these is expected as part of the Smart Meter roll-out, to allow Suppliers to correctly manage microgeneration export. IREG walked through a ‘strawman’ of a new MAP, providing comments for the Proposer’s consideration. The IREG suggested that the Proposer raise a Change Proposal (CP) to take the changes forward, mindful of the timescales of progressing and implementing the CP if it has the targeted November 2018 implementation date.

MIF257– Meter Serial Number not on DCC Inventory

Meter Serial Number (MSN) is used on many Data Flows to provide a link between a meter and Meter Point Administration Number (MPAN). For Data and Communications Company (DCC) enrolled meters that data is unavailable on the DCC inventory, so when a Change of Supplier (CoS) occurs, it cannot be provided to agents to ensure the correct meter is linked to the MPAN. This MIF seeks to add the Globally Unique Identifier (GUID) to certain Data Flows so that the relationship is established. IREG noted that a similar solution was considered under the Smart Energy Code (SEC); all be it, to include the MSN in the DCC. However, this was rejected on cost grounds, even though it was supported by the industry.

Two options were presented by the Proposer. IREG commented on these, which the Proposer will consider and look to bring the CP drafting back to the April IREG meeting for comment and look to go out for Impact Assessment at the April MDB meeting too.

MIF258 – Near Time Improvements to Electricity Meter Technical Details

IREG noted that MIF258 was raised following a request of the Ofgem Switching Programme and the MRA Executive Committee (MEC). It seeks views on the potential scope and approach for reconciling electricity Meter Technical Details (MTDs) held in Suppliers and Meter Operators (MOP) own systems with those held in the ECOES. This near-term reconciliation seeks to address potential inconsistencies and obsolete MTD records that could have a negative impact on the reliability of consumer switching and billing, prior to the implementation of the new switching arrangements. The MIF also seeks consideration of dual fuel in any reconciliation exercise; and steps to ensure that the MTD quality is maintained on an enduring basis following the first reconciliation exercise(s).

IREG agreed that a Special IREG should consider this, with input from the Association of Meter Operators. IREG agreed that this Special IREG should meet on 28th March 2018, where the scope of activities will be determined.

MIF259 – Update Contact Types and their Mandatory Status

IREG noted that following the completion of actions to address MIF218 (MRA Industry Contacts); and ongoing maintenance of contact records by the Contract Manager, a validation and cross-check of the Contact Types that now exist in the Industry Contacts Database was performed against the equivalent SPAA schedules. This included identifying if the contact type was Optional or Mandatory for Suppliers and/or Distribution Businesses.

IREG commented on the appendix, which details the current list of Contact Types. This included:

  • Concern that smaller parties will have the same contacts at all levels, which in times of absence can cause issues. However, it was noted that most will have out of office notification with alternate contacts.
  • Noted that additional contacts were added to align with the SPAA; requested that it be raised with SPAA that it carry out a similar exercise.
  • Concern that parties that have completed Controlled Market Entry (CME) have not updated contact details where the company has been sold on.

IREG agreed to issue a request for information (RFI) after Easter and consider the responses at its May meeting.

Special ECOES IREG Update March 2018

A Special IREG meeting  took place on 6th March 2018 and discussed the following:

ECOES2 Development

The group was given an update on the current position of the developments of phase 2 which are currently in test and expected to be released at the end of March.

A paper had been provided outlining some of the General Data Protection Regulations (GDPR) considerations and data items held within the current ECOES1 version, such as “Date of Birth” and “Payroll Number”. These were proposed as not required due to being seen as “personal data”. One party noted they used the Payroll Number and it would be helpful to understand if other parties use either of these fields. If used, some action will need to be taken if the parties are slow in migrating from ECOES1.

IREG noted that there could be challenges for some parties who are yet to migrate to ECOES2 in meeting an end date of May 2018, if that was a desired outcome to meet GDPR needs. Notification may be required from MRA Executive Committee (MEC) to highlight any risks or potential non-compliance.

IREG discussed the letters produced by the Distribution Network Operators highlighting that all letters are still held in ECOES1, whereas in ECOES2 a change has been introduced to delete the letters after 7 calendar days. Again, if migration from ECOES1 is delayed a process will need to be added in to delete all the letters held, and then implement a weekly check to delete any new letters produced.

IREG discussed the 3 options provided on Access Controls for ECOES2. The group noted that although the ideal would be to have one option as ECOES is a central system, the reality was that many users who access ECOES may have company emails for internal use only. Thus, some options were still needed and it should be for each company to decide which option they choose in managing users and passwords, and it is for each company to manage their own GDPR and IT security arrangements.

IREG noted that the User Requirement Specification (USR) would need to be updated based on previous discussions on the Access Controls along with some checks on spelling and grammar. Some process areas were highlighted that require a wider post-implementation review such as Non-Domestic Customers (NDC), MRA Agreed Procedure (MAP) 14 (Procedure for the Allocation of Pre-Payment Metering (PPM) Payments Transacted Against an Incorrect Device and the D0312 (Notification of Meter Information to ECOES). IREG agreed for an updated URS covering all the agreed amendments will be issued as part of the post meeting documentation for review and final comment.

Next standard meeting

IREG will next meet on 14th March 2018.
