DR1105 V1 - Change to MPD36 - Change of Grouped MPRN_No CoS

  • Change Request

    • The unmetered market has grown significantly since Market Opening in 2005

    • RMDS-driven process review project has assessed the processes in terms of bottlenecks, weaknesses and areas for improvement

    • This second DR has been created to facilitate changes to MPD 36 - where there is no CoS

    • Previous DR from last HWG – DR1084 with CoS

  • At today’s Meeting

    • Classification as ROI-specific

Dr1110 v1 updates to es ni market message implementation guides and retail market procedures

DR1110 V1 - Updates to ES NI Market Message Implementation Guides and Retail Market Procedures

  • At today’s Meeting

    • Classification as NI-specific

Dr1106 v1 update to nie revenue protection process

DR1106 V1 – Update to NIE Revenue Protection Process

  • Change Request

    • Process Change

      • Where a RP Inspection Visit detects an unauthorised re-energisation of a domestic premise the RPU will replace the credit meter with a prepayment meter, preloaded with a small amount of credit and disabled from vending on the PRI system.

      • The RPU team will then email the registered Supplier for that premise to notify them that they must submit 017 & 030 market messages to request the re-energisation and (retrospective) replacement of the credit meter with a prepayment meter.

      • The email will contain an appointment ID for use on the 017(E01) & 030(K05) market messages.

      • RPU will complete the 017 & 030 orders and the 332 market message will be sent to the Supplier as confirmation of the meter exchange.

    • The 131[C1] market message that is sent on completion of the RP Inspection Visit will have

      • - Work Type Code = W402 - RP Inspection Visit

      • - Outcome Reason Code = C008 - Revenue Protection Issue

      • This requires the Code Value ‘W402’ on Data Item ‘Work Type Code’ to be changed to ‘Valid in NI’ in the HBL Data Code.

  • At today’s Meeting

    • Approval as DR and as MCR

Dr1107 v1 new connection card required code on 102p

DR1107 V1 - New 'Connection Card Required' code on 102P

  • Change Request

    • Introduction of a new ‘Provisional Acceptance Completion Requirement Code’ code of “CCR – Connection Card Required” for the 102P market message to notify the Supplier that a Connection Card is required before the meter works requested on the 010 (CoS) can be completed.

    • This 102P will return this code when

      • - an 010 (CoS) is submitted with Meter Works included, and

      • - the Meter Works involve a change to an MCC which includes heating, and

      • - the premise does not currently have an MCC which includes heat.

    • NIE need to know the additional Heating Load that is required at the premise and the Connection Card will provide this information.

    • The CoS meter works will not proceed until NIE have received a valid Connection Card from the Customer.

  • At today’s Meeting

    • Approval as DR and as MCR

Dr1108 v1 update to description and usage of delay reason code de01 on 130d

DR1108 V1 - Update to description and usage of Delay Reason Code ‘DE01’ on 130D

  • Change Request

    • Request proposes three changes

      • That the description for Delay Reason code ‘DE01’ is changed from “Completion Certificate Required” to “Completion Certificate/Connection Card Required”

      • That ‘DE01’ will be used in NI

      • That ‘DE01’ will be sent on the 130D to notify Suppliers that a requested change of MCC will be delayed because a new Connection Card will be required from the customer before the work can be completed.

    • This situation will arise where an MCC which includes heating is being requested and the premise does not currently have an MCC which includes heat.

    • NIE need to know the additional Heating Load that is required at the premise and the Connection Card will provide this information..

  • At today’s Meeting

    • Approval as DR and as MCR
