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that although the EAC may not exist after 2020, that this MIF might raise a short-term change, or the MIF might be withdrawn.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.

IREG Update February 2018

IREG met on 14th February 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:

  • WP76 can be progressed to a Change Proposal (CP) to remove it from the WPPS.
  • WP122 and WP146 should be considered in line with MIF238 and MIF255.

The solutions proposed by Prepayment Metering Forum (PPMF) for the Pre-payment WPs should be progressed, including consultation with the Association of Meter Operators (AMO) and ELEXON where required.

A review of the outstanding items is now required to identify the next WP to be reviewed.

MIF231 – ECOES Search Facility

IREG noted that the new functionality has been implemented and the maximum search value be left at 600. The MIF will be closed.

MIF238 – Changes to WP152 Requesting Additional or New MPANs

IREG walked through the solution proposal for changes to the Electricity Central Online Enquiry Service (ECOES). Several questions and 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 then be required to develop a MRA Agreed Procedure (MAP), incorporating the new ECOES functionality.

MIF247 – ECOES Password reset access

The TSP had confirmed that the changes could be delivered without any release costs if progressed as part of ECOES2. The proposal was agreed ex-committee and funding was approved by MEC/Board. This MIF will be closed.

MIF251 – Review of DTC CP 3529 Provision of Last Meter Inspection Date

The proposed solution was discussed and a few minor amendments were identified. It was agreed that with these amendments the CP should be submitted to the MRA Development Board (MDB) and the MIF be closed.

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

Several approaches to enable Gas Meter Asset Managers (MAM) to report asset condition codes via an electricity Meter operator (MOP) were discussed, with the solution proving quite complex. As no quantification of the size of the issue was included in the MIF, IREG was unable to assess the benefit vs cost of any of the approaches. IREG noted that there would be complexities on who the Distribution Network Operator (DNO) would charge for the work carried out. The Proposer was requested to obtain further information from the Distribution Connection and Use of Systems Agreement (DCUSA) Interventions Working Group (IWG).

MIF253 – Improving  Accuracy of Customers’ Annual Consumption at Point of Sale

This issue was to improve customer switching and calculation of consumer costs, it is looking to align with the gas change already in to have the Annual Quantity (AQ) available. IREG noted that the Ofgem Code Review is looking at moving to mandatory Half Hourly metering and settlement, which would negate the need to use EAC/Annualise Advance. It was suggested that the Average EACs from Market Domain Data (MDD) could be used as an alternative. The Proposer was requested to consider the long-term requirement for this issue and the feedback received.

MIF254 – Review of J1839 ‘SMETS Version’

This was a new MIF that was raised by the Smart Energy Code Company (SECCo) after the MDB meeting in December 2017. It looked to investigate MRA impacts and solutions required to accommodate the new Smart Metering Equipment Technical Specification (SMETS) version control rules. Two Data Items (J1839 and J0483) were discussed and it was agreed that there was no benefit in making changes to the format of these Data Items, as they are not used to identify the SMETS version presently. Firmware information would be sourced direct from the Data and Communications Company (DCC). Instead, an update to the descriptions used in these Data Items was agreed to be progressed to a CP and the MIF closed.

MIF255 – Raising NHH Export MPANs for Smart

This issue looks to implement defined response time for Distribution Businesses (DBs) to respond to 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. It was noted that some of these may be bulk requests for new NHH Export MPANs from Suppliers to DBs. It was recognised that the proposed solution for MIF238 could support this MIF also, and that any MAP amendments would have to be co-ordinated for both MIFs. The Proposer agreed to draft a straw man for the processes in consultation with a DB representative, including single and bulk requests.

MIF256 – Data Flow changes to facilitate P354

This was a new MIF raised after December’s MDB, by ELEXON. It looks to progress changes to the Data Transfer Catalogue (DTC) required to support the solution for Balancing and Settlement Code (BSC) Modification Proposal P354. It was agreed that the proposed solution should go to CP and the MIF be closed.

ECOES

The updates to the User Requirement Specification (URS) for ECOES Phase 1 were reviewed. Concerns were raised regarding compliance with General Data Protection Regulations (GDPR) of the URS in its entirety. It was agreed that a GDPR assessment should be completed followed by a Special IREG meeting scheduled to complete the review of the full URS following the assessment.

Special IREG Update January 2018

IREG met on 31st January 2018 and discussed the following:

MIF248 – Plot Addresses

Xoserve presented an overview of the data cleanse exercise being undertaken in the Gas market, to update Plot Address data held in UK Link. The group discussed similarities and processes that could be useful for a similar exercise on the Electricity data.

The requirements and source of reporting were agreed, including content and frequency for Ofgem. It was requested that a solution proposal be obtained from the service provider. Once received, a request will be sent to the MRA Executive Committee (MEC) for funding approval.

The draft Request For Information (RFI) questions were reviewed. It was agreed that following the updates discussed during the meeting, the RFI would be issued to stakeholders.

Members agreed that a proposal for MRA Agreed Procedure (MAP) steps to standardise the data cleanse and define time scales would be developed before being circulated to all parties for comment, via Huddle.

Next meeting

IREG will next meet on 14th February 2018.

IREG Update December 2017

IREG met on 13th December 2017 and discussed the following MRA Issue Forms (MIFs):

MIF219 – Full Review of Working Practice Product Set

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

 

  • WP7 can be progressed to CP to remove it from the WPPS.
  • WP107, WP125 and WP144 investigation should be carried out to confirm that they should be included in Balancing and Settlement Code (BSC) configurable items or guidance.

The following WPs will be reviewed next – WP76 and WP122.

 

MIF238 – Changes to WP152 Requesting Additional or New MPANs

IREG noted that the proposal is to change the current process and use ECOES2 to facilitate requests for additional or new MPANs. This is could make the D0168 and D0169 Data Flows redundant. IREG requested that Gemserv seek an initial impact assessment from the ECOES service provider to determine the estimated costs of implementing the solution and any alternatives. IREG also requested that the Data Transfer Service provider identify the total number of D0168 and D0169 Data Flows are received; and the total number of requests for MPANs contained in these flows. It acknowledging that a large proportion are requested via email.

 

MIF240 – Missing Register Mapping Coefficient for Non-Settlement Meter on D0367

IREG noted that the Proposer has closed the MIF following advice received by MRASCo from ELEXON. It recommended against updating the D0367 Data Flow as the two metering arrangements described in BSC Procedure (BSCP) 516 are likely to persist into the smart arrangements. The non-settlement registers were included in the D0150 and D0149 Data Flows to allow the NHHDC to read the registers. For DCC-serviced SMETS v2.0 meters, the Supplier can retrieve non-settlement registers directly from the meter.

 

MIF246 – Review of MAP04 process for full and Selective refreshes

IREG advised that MAP04 is not clear and many parties avoid using it as it can be an expensive process to follow and compliance with BSC settlement drivers outweighed any benefit of using the process. The Proposer advised that the MIF should be closed therefore, IREG recommended that a CP should be raised to remove WP16; and that the detail not be added to MAP04 nor the DTC.

 

MIF247 – ECOES Password reset access

IREG agreed that the User Maintenance function should remain as is, but that a new ‘Password Reset’ function be created. The requirement and cost will be investigated with the technical service provider.

 

MIF249 – Review of the Distribution of Unallocated Transactions in MAP14

IREG agreed that the process for distribution of unallocated prepayment transactions was unclear. It noted that two PPMIPs had interpreted the process differently, which is inconsistent with how others have interpreted it for this year’s activity. IREG agreed to that some additional steps were required throughout the procedure including positive confirmation from the PPMIP that the data is complete. A Proposer was identified to raise a CP to take this forward in time for the 2018 run.

 

MIF250 – Review of the D0268 ‘Half Hourly Meter Technical Details’ Data Flow

IREG provided comments on the various changes to the D0268 Data Flow identified in the MIF. The Proposer will update the solution after taking in to consideration the feedback, with the aim of a second review of red-lined changes at the January IREG.

Special IREG Update November 2017

A Special IREG met on 22nd November 2017 to discuss MRA Issue (MIF): MIF248 – Plot Addresses.

The IREG agreed several recommendations to the MRA Executive Committee (MEC). These included:

  • providing guidance (to later be included in a new MRA Agreed Procedure (MAP) on sources of data for validation and how best to cleanse data;
  • issuing a request for information;
  • reporting against addresses where ‘plot’ is contained in lines one to three of the address; and another for where post codes are incomplete (and are not unmetered); and

further meetings of IREG to take the above forward, with coordination with Xoserve and potential cross-code meetings to find common solutions to address the symptoms and in the long term, underlying causes

IREG Update November 2017

IREG met on 8th November 2017 and discussed the following MRA Issue Forms (MIFs):

Special IREG meeting for MIF248 – Plot Addresses

IREG requested that a special IREG meeting be organised to be held on Wednesday 22nd November 2017. Notification will be sent via the IREG Huddle workspace and regular IREG members will be ensuring any business experts are notified and invited accordingly.

 

MIF244 – Review SPF102 following Impact Assessment

IREG discussed the draft redlined changes to Data Item J0385 (Communications Address), Data Flow D0268 (Half Hourly Meter Technical Details) and Annex C Rules for the D0268 and agreed with the additional points made and that the Proposer should proceed to Change Proposal (CP).  It was requested that the CP be submitted in January 2018, to allow review (under another MIF) of other items associated to the D0268 and any necessary resulting adjustments to be captured.

 

MIF236 – DTC Annex C – Wording not mandating population of data items

IREG reviewed the responses to a Request for Information and noted that all instances of ‘should’ identified in Annex C for the following Data Flows could be changed to ‘shall’: D0055, D0148, D0205, D0268, D0300, D0301, D0303, D0312, D0313 (see DTC for flow names). These instances will be included in a CP that will also look to introduce a contents page to Annex C.

The instances of ‘should’ in Annex C for the D0225 and the D0367 require further investigation to determine if they need to be changed to ‘shall’.

 

MIF237 – ETWG Contract Manager Guidance

A revised version of the guidance document was reviewed and no comments were received on the draft wording. Following a minor update to the Appendix and final confirmation from the Erroneous Transfers Working Group (ETWG), IREG agreed it would be ready to be included in the accession information sent to new MRA parties.

 

MIF239 – Permissible symbols included in email addresses sent through the DTN

Following review of data provided by ElectraLink showing the instances of invalid characters sent via the DTN, it was determined that the volume of rejections is insignificant compared to the transactions sent across the DTN. No significant issues were identified and therefore IREG agreed no action was required and the MIF could be closed.

 

MIF242 – Notification to Supplier of a Customer Preferred Agent’s contact end

ELEXON presented an overview that looks to address issues where a Customer’s direct contract with an agent (Meter Operator/Data Collector/Data Aggregator) ends and the Supplier is not notified in time, so that it can either change the agent or agree terms with the existing agent. IREG advised that as agents are not a party to the MRA but are governed under the Balancing and Settlement Code (BSC) Procedures, an addition to the BSC is the correct solution.

 

MIF243 – Adding Supplier as recipient of D0005 ‘Instruction on Action’ Data Flow

IREG agreed that the proposed solution for this MIF – to add an instance of the D0005 Data Flow from Meter Operator (MOP) to Supplier – would improve the process for Suppliers and MOPs. An associated BSC change will be required with the MRA DTC change and should be progressed in line.

 

MIF245 – DTC Annex D use of ‘Not Used’ as the description of a valid value

IREG discussed the instances of valid values with a description of “Not Used”. It was identified that these values have been purposely left in the Data Transfer Catalogue (DTC) and set to ‘Not used’ to allow historic instances of the value to still be transmitted. It was not thought that any of the instances are currently causing issues and therefore a change was not deemed to be beneficial.

 

MIF246 – Review of MAP04 process for full and Selective refreshes

The Proposer requested that this be rescheduled to the December IREG meeting.

 

MIF247 – ECOES Password reset access

IREG agreed that splitting out the password reset access would be useful for parties and that the requirement and cost should be investigated with the technical service provider.

 

MIF219 – Full Review of Working Practice Product

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

  • WP144 and WP147 can be progressed to CP to remove them from the WPPS.
  • WP150 will be progressed to CP to add rules to Annex C and remove the WP.
  • WP6 – the proposer will investigate aligning the MRA and BSC.

The following Working Practices will be reviewed next – WP7, WP107 and WP125.

IREG Update October 2017

IREG met on 11th October 2017 and discussed the following:

MIF219 – Accuracy of Working Practice Product Set (WPPS)

  • Working Practice (WP) 16 (MPAS – Differentiation between Supplier Full or Partial Refresh (D0204)) – IREG agreed that the details can be added to MRA Agreed Procedure (MAP) 04 (Error Resolution and Retrospective Manual Amendments). However, IREG noted that this would require a wider review of the MAP, therefore agreed to close WP16 from MIF219 and for a separate MIF to explore this.
  • WP66 (Change of Measurement Class – NHH to HH) and WP116 (Change of Measurement Class from NHH to HH Coincident with CoS) – IREG agreed that WPPS Change Proposals (CPs) should be raised to remove these WPs as the detail was captured in relevant Balancing and Settlement Code (BSC) Procedures (BSCPs).
  • WP144 (The use of Site Visit check codes 02 and 20) – IREG agreed that the WP could be removed, however, believe that the rules would be better accommodated with the BSCP where the processes which use the codes are outlined. ELEXON to consider raising a BSC change to include the codes.
  • WP147 (Auxiliary Metering Information) – IREG noted that this was originally a short-term solution pending DTC changes that have since come in to effect. As such, WPPS CP should be raised to remove this WP.
  • The next WPs to be reviewed will be WP6 (Determining the Meter Reading on Change of Supplier (MRoCoS)) and WP150 (Advanced Meters: Auxiliary Metering Information)

MIF225 – Update on legal counsel for Intellectual Property drafting

Gemserv presented the responses from the MRASCo lawyer on the clarification questions. IREG noted the responses, but still was not clear on what the issue the MIF intended to address was nor why the MRASCo Board wanted IREG to consider the MIF. As such, this was passed back to the Board to clarify.

MIF235 – Review of MAP17 MIF process

IREG agreed amendments to both MAP17 (Issues Resolution and Change Management) and the IREG Terms of Reference to better clarify the process and timings for the progression of MIFs.

Gemserv is making MIFs available via the MRASCo website in the short-term, though there are issues with those that do not include an implementation date. The new website requirements include these in the Change Tracker as the long-term solution.

MIF237 – Contract Manager Guidance Document

The draft document produced by the Erroneous Transfers Working Group (ETWG) is still under development following previous IREG comments and will be presented to the next IREG.

MIF238 Changes to WP152 Requesting Additional or New MPANs

IREG considered the processes and noted that the Proposer will work with a Supplier to bring either an amended MIF or new MIF to the next IREG.

MIF239 – Permissible symbols included in email addresses which appear in dataflows sent through the DTN

This MIF seeks to address issue highlighted in the impact assessment of DTC CP3515 (Allowing the use of an underscore). Specifically, that the CP had not gone far enough to encompass enough symbols in the J1844 (Customer Preferred Contact Details) or J2060 (Contact Email) that were leading to customer email rejections.

IREG agreed that the J0012 (Additional information), where this is used in the D0012, was also relevant. However, it also considered the potentially large number of flows to be affect if the J0012 is included in this MIF, and the amount of testing that would be required by parties. As such, it agreed to determine the most frequently rejected email addresses characters within the last six-months.

MIF240 – Missing Register Mapping Coefficient for Non-Settlement Meter on D0367’

IREG noted that the D0367 (Smart Meter Configuration Details) was created following the approval of BSC Modification P302 (Improve the Change of Supplier Meter read and Settlement process for smart Meters). It therefore asked ELEXON to consider whether there were reasons why Register Mapping Coefficient for Non-Settlement Meter were not included in the Data Flow at the time.

MIF241 – Enabling identification by gaining Supplier of a Customer Preferred Agent

The initial discussion of this MIF explored one of the three potential solutions previously discussed under closed MIF234 (Potential Change Proposals to improve BSC processes in identifying and managing Customer Preferred Agents). The other two associated MIFs will be addressed at a future IREG.

IREG considered the two broad solutions of either ECOES changes or DTC changes with amendments to the registration process. However, noted issues with both options. ELEXON agreed to consider the feedback and come back to the next meeting with either a more detailed solution for consideration; or to close the MIF if it agrees that the costs and issues it introduced outweigh any perceived benefits.

MIF244 – Review of SPF102 following Impact Assessment – Review solution

MIF244 was raised to allow IREG to consider the responses to Solutions Pre-Assessment (SPF) 102 (Interoperability in the sub 100kW Half Hourly Market Post P272). IREG suggested several amendments and alternative approaches to the proposed solution. The focus of these was to avoid any unnecessary changes to Distribution Businesses systems that D0268 Data Flow changes would introduce. Following feedback from IREG, the Proposer agreed to review the suggestions and bring updated solution drafting back to the next meeting for further discussion.

Next meeting

IREG will next meet on 8th November 2017.

 

IREG Update September 2017

MIF215 – Metering Commission Flow

ELEXON has confirmed that this will be progressed to Change Proposal (CP) with the aim of submitting to September’s MRA Development Board (MDB).

MIF219 – Accuracy of Working Practice Product Set (WPPS)

  • Working Practice (WP) 45 (NHH Metering – Timing of when D0052 may be sent), WP61 (Content of D0148 between a Supplier and its Agents) and WP74 (Use of D0010 and J0171 on a Change to Metering System Configuration) have been cross-checked against the Balancing and Settlement Code (BSC) Procedures (BSCPs) by ELEXON, and are satisfactorily included. The CPs to remove the WPs will be progressed.
  • WP75 (Use of ‘Date and Time’ in D0010 for HH Market) – a request for information (RFI) was inconclusive on where the rules should be moved to and parties confirmed that either would achieve the aim. The Proposer will raise their preferred solution as a CP.
  • A draft solution was presented for WP129 (Usage of DTC flow D0290 “Instruction to Read Meter” (DP to DR)) and it was agreed that it should progress to CP.
  • WP16 deferral by MDB will be discussed at IREG 17_10.
  • It was also agreed that towards the conclusion of this MRA Issue (MIF), a CP will be raised to add a contents section to the beginning of the Data Transfer Catalogue (DTC) Annex C (‘Rules for the completion of Data Flows), to allow easier usage and navigation of the document.
  • The next WPs to be reviewed will be WP144 (The use of Site Visit check codes 02 and 20), WP150 (Advanced Meters: Auxiliary Metering Information) and WP6 (Determining the Meter Reading on Change of Supplier (MRoCoS)).

MIF225 – Update on legal counsel for Intellectual Property drafting

Gemserv advised that this is pending response from the lawyer on the clarification questions, therefore was not discussed.

MIF231 – ECOES Search Facility

Following the feedback from IREG, the MRA Security Committee (MSC) has requested that the report that shows the levels of searches is re-run to allow a further assessment of the cap numbers. IREG will await further output from MSC.

MIF232 – Issue with Suppliers sending D0135 to Distribution Companies

Following the results of an RFI, the Proposer directed that this MIF be closed as it was confirmed that Suppliers can populate the 60H group of the D0135. Any D0135s received by the Distribution Network Operator (DNO) from the Supplier without this group populated with the asset condition code will be rejected.

MIF233 – Creation of a ‘rejection flow’ response to a request to send a D0215

ELEXON has confirmed that this will be progressed to CP with the aim of submitting to September’s MDB.

MIF234 – Potential Change Proposals to improve BSC processes in identifying and managing Customer Preferred Agents

The initial discussion of this MIF identified that there are multiple issues to be addressed. Therefore, IREG recommended that the MIF should be Closed and three new ones raised to address the following issues:

  • How does a Supplier identify that a new Customer has a direct contract with preferred agents?
  • How does a Supplier identify that an appointed agent’s direct contract with the customer has ended?
  • How does the supplier get visibility of the fault resolution process, as currently they do not see the D0005 ‘Instruction on Action’ Data Flow sent between Meter Operators and Data Collectors?

MIF235 – Review of MAP17 MIF process

IREG agreed that the scope of the MIF was limited to how MIFs are scheduled. It agreed that the inconsistencies in MRA Agreed Procedure (MAP) 17 (Issues Resolution and Change Management) should be amended to clarify that MIFs received after MDB paper day can be scheduled for the next IREG, at the discretion of the Chair. Gemserv will propose changes to the MAP and MDB and IREG Terms of Reference to achieve this.

Gemserv will also look at making MIFs available via the MRASCo website in the short-term; the new website requirements include these in the Change Tracker as the long-term solution.

MIF236 – DTC Annex C wording not mandating population of data items.

This MIF identifies instances in the DTC Annex C where the word ‘should’ potentially need to be changed to ‘shall’, as the rules are mandatory. It was agreed that an RFI be issued to understand the impact of changing each instance of ‘should’ to ‘shall’.

MIF237 – Contract Manager Guidance Document

The draft document produced by the Erroneous Transfers Working Group (ETWG) was reviewed by IREG. Although it was agreed that a guidance document, to be issued to new parties and hosted on the website was useful, the wording needs some revision.

IREG Update August 2017

IREG met on 9th August 2017 and discussed the following:

MIF215 – Metering Commission Flow

ELEXON provided an update on the development of the Metering Commissioning Data Flows, as discussed at the last workshop.

The workshop has developed two Data Flows:

  • For the notification of commissioning information and status, sent by the Distribution Network Operator (DNO) to the Meter Operator (MOP); and
  • For the notification of additional defect information and commissioning status, sent by the MOP to the Supplier.As part of the development of these Data Flows, several Data Items are being developed, along with a list of reason codes to be used to notify defect/omission reason.Further consideration is being carried out by ELEXON on the associated risks posed by the role of National Electricity Registration Scheme (NERS) accredited Independent Connection Providers (ICPs) in the process. A BSC Issue may be raised to consider this further.ELEXON will update IREG at the next meeting, on progress.
  • ELEXON is also proposing to amend Metering Code of Practice (CoP) 4 regarding the retention of commissioning records. This is because under the proposed changes to the commission process, the DNO and MOP will hold the commissioning records from their respective commissioning actions.
  • ELEXON also advised that changes to the relevant processes captured in the Balancing and Settlement Code (BSC) Procedures (BSCPs) are being developed. These changes will set a maximum of 80 Working Days to complete the commissioning processes, ahead of the second reconciliation run for settlement (R2) at 84 Working Days.
  • It is intended that both Data Flows will also be used on a change of MOP, sent by the old MOP to the new. The first flow is intended to pass on relevant commissioning information to the new MOP. The second flow would be used where part or all the commissioning information is incomplete. The group felt that the utility of these flows in MOP to MOP communications will negate the need for the original third Data Flow.

MIF233 – Creation of a ‘rejection flow’ response to a request to send a D0215

ELEXON presented an overview on its new MRA Issue (MIF). This proposes a new Data Flow where by the DNO can reject a request from the MOP to send a D0215 (Provision of Site Technical Details) Data Flow. This is so that the DNO can advise, for instance, that it is not the equipment owner or the metering equipment was installed pre-BSC Modification P283 (Reinforcing the Commissioning of Metering Equipment Processes).

This MIF is to address two issues:

  • The current industry issues and complaints around the sending of the D0215 Data Flows from a DNO to a MOP where a request for the flow may be inappropriate; and
  • BSC auditor identified issues around the quality of information provided in the D0215 Data Flow, particularly on communications sent pre-P283.

MIF219 – Accuracy of Working Practice Product Set (WPPS)

Gemserv presented draft changes to four Working Practices (WPs):

  • WP45 – NHH Metering of when D0052 may be sent;
  • WP61 – Content of D0148 between a Supplier and its Agents;
  • WP74 – Use of D0010 and J0171 on a Change to Metering System Configuration; and
  • WP75 – Use of ‘Date and Time’ in D0010 for HH market.

Pending confirmation by both ELEXON and Gemserv as to whether the provisions in the Working Practices relating to settlement are already captured under the BSC and its subsidiary documents, IREG agreed that the four WPPS CP should be raised to delete the WPs; and that no changes to the Data Transfer Catalogue (DTC) will be required. If, however, the assessment identifies that the provisions from a settlement perspective are not captured in the BSCPs, then the DTC CPs, along with the WPPS CPs can be raised.

For WP75, IREG agreed that if the BSCPs do not capture the requirements; or that there is no need for the notes to be included in the DTC for non-settlement purposes, the Gemserv should issue a request for information (RFI). This will be to determine whether the changes to the DTC as presented by amendment of the D0010 (Meter Readings) should instead be captured in the J0016 (Reading Date & Time) Data Item. In addition, any RFI should seek to determine if the notes should apply to elective Half Hourly (HH) meters, non-Data Communications Company (DCC) HH meters or both.

Gemserv also presented three additional WPs for the next reviews. IREG agreed that these should be progressed to review, which should include an assessment by both ELEXON and Gemserv on whether the provisions are already captured in the BSCPs or needed for non-settlement purposes. These being:

  • WP129 – Usage of DTC flow D0290 “Instruction to Read Meter” (DP to DR);
  • WP144 – The use of Site Visit check codes 02 and 20; and
  • WP150 – Advanced Meters: Auxiliary Metering Information.

MIF225 – Update on legal counsel for Intellectual Property drafting

Gemserv advised that the MRASCo Board has sought legal counsel on the Intellectual Property drafting. Further clarification is being sought, which includes the impacts on Parties and third-parties; and on cross-code working.

MIF227­ – Referral from MAP10 to MAP12

IREG discussed the wider considerations regarding the associated processes captured by MRA Agreed Procedures (MAPs) 10 and 12, as well as the mismatches. It was agreed that a MAP CP should be raised to clarify that the processes apply to Domestic HH sites, as well as Non-Half Hourly sites. A Sponsor for the CP was identified, who will also consider whether to progress changes (either as part of the MAP CP or as a separate MAP CP) to include Co-operative Objections

  • MAP 10 – ‘Resolution of Erroneous Transfers’
  • MAP 12 – ‘Customer Requested and Co-operative Objections’

MIF231 – ECOES Search Facility

MIF231 seeks to amend the ECOES User Search functionality to enable the maximum number of searches be set at a Company level. Along with initially resetting the maximum numbers to a multi-tier approach. IREG questioned the rationale for the change, and specifically the maximum number of searches for each tier. It was noted that the rationale is associated with data protection risks, identified as part of the MRA Security Committee’s (MSC) assessment of General Data Protection Regulation (GDPR). IREG requested that MSC release the rationale so that IREG could agree on the proposed solution.

MIF232 – Issue with Suppliers sending D0135 to Distribution Companies

MIF232 seeks to address issues where Suppliers are continuing to send D0135 (Asset Condition Report) Data Flows to Distribution Businesses with the relevant Asset Condition Code in the “Additional Information” field due to the restriction placed on the Supplier in the 60H group within the flow. IREG agreed to issue an RFI to determine from Suppliers:

  • in what situations do they send the D0135 flow; and
  • when it is sent, how they identify if the equipment is under the DNO or MOP responsibility.

Next meeting

IREG will next meet on 13th September 2017.
