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.
