– DR 0124 will be re-issued by RMDS



• Action Item 39 – To get information on the volumes of readings that are currently rejected because they are outside of the tolerance ranges for the different DGs

– Daily figure of 4% - 6% of all NQH readings are initially implausible

– Reduces to 1% outsorted after re-estimations



• Action Item 41 – Raise a DR to propose the initiation of the updates to the Central Market Systems of a QH to QH meter replacement at the same time as the MV90 is updated

• Action Item 156 – Update on ‘Universal Meter’ (3 register meter)

The proposed approach is:

New Connection– Conventional MCCs will be used i.e. 24hr. or Day/Night– The service order will specify the MCC requested on the

application form.– At connection, the NT takes the appropriate readings and

completes the service order.– ESBN will do a development to ‘force’ the meter characteristics at

completion into the mode appropriate to the MCC– Meter Reader handhelds will hold only the registers for the MCC



• Action Item 156 – Update on ‘Universal Meter’ (3 register meter) (contd.)

Change in MCC– Conventional MCCs will be used i.e. 24hr. or Day/Night– The service order will specify the MCC requested on the supplier

message– The NT does not change the meter but takes the appropriate

readings and completes the service order.– On completion in database, the meter characteristics into the

relevant mode depending on the MCC.– The Meter Reader will ‘see’ only the relevant registers on his/her

handheld.



• Action Item 169 – Examine preventative measure with the message reconciliation and resending processes to ensure there are no exceptions over the Christmas period

– There were no message resends over the Christmas period



• Action Item 174/188 – RMDS to Advise IGG of assurance measures to detect issues with future schema

changes by IPT stage

– In the future, the Hub team will carry out extra tests prior to the issue of a new draft schema using a software tool:

• a compare between the live schema and the new schema to ensure that the only differences are those covered by MCRs

• To validate a sample of real XML messages against the draft schema

– Incorporate dependency for sign-off on completion of internal Regression Testing in advance of commencement of IPT



• Action Item 186– RMDS to provide update at the next IGG on message monitoring over the Christmas 2007/New Year 2008 period– Messages backed up in the Hub over the Christmas period and

were released on 29th December – There was an accidental second batch run of the QH readings

job which resulted in duplicate 341 messages issuing for 29


Action Items to be carried forward

Discussion Requests & Market Change Requests

Susan Morrissey, RMDS


MCR 0063 - Provision of reconciliation data

1. Aggregation input file data:

• MPRN• Supplier Unit• SSAC• DLF• Usage factor by time

of use• Load Profile

2. ESBN records at the time of the aggregation run:

• MPRN• DG• Load Factor (if MD)• Usage Factor• Load profile per time of

use• Whether actual or

estimated consumption

MCR ready for circulation.

Requirement: For all MPRNs included in a specified aggregation run, 2 data extracts on request:


MCR 0063 - Provision of reconciliation data

Assumptions

1. Suppliers can validate QH Export Aggregations by using the existing data (Generator Unit / Export Arrangement).

2. Timing of extract runs to fit in with the live production schedule

3. Output format will not be in the form of new messages

4. The frequency and costs of producing the reports would need to be discussed as an MRSO item at future IGGs.


DR 0117 New Status Message for Meter Works and Special Read requests

• Where we are:– DR0177 circulated and agreed

– New IGG Action (18.10.2007):• add the list of codes• clarify how these messages tie in with

chargeable and non chargeable transactions (in DUoS) when there is a cancellation.

MCR 0127 - Decouple Connection Agreement requirement from Change of Supplier

• In order to maximise potential value to suppliers, will request impact on the following alternative proposal:– Removal of CA requirement for all

MPRNs connection at low voltage.• Advantages:

– Would remove a larger number of sites from the requirement.

– Compatible with NI design.

• DSO are in agreement in principle


Market Change RequestDR 0113 Supplier of Last Resort Update

DR ready to be circulated to the market• SoLR Process Assumptions

– For a defaulting Supplier only. Cannot be initiated by a defaulting Supplier Unit.– On day 1 all MPRNS are to be reviewed by MRSO / ESBN for any outstanding service orders.– The data file is issued by MRSO on Day 1 and a revised data file will be issued by close of business on day 19 to the SoLR -

excluding any MPRNS that have since been registered to Alternate Suppliers.– Existing CoS’s to the exiting Supplier are to be cancelled and notified by MRSO.– Existing CoS’s to Alternate Suppliers are processed to the SoLR event date and procedures.


Market Change Request

DR 0113 Supplier of Last Resort Update

• SoLR Assumptions– Alternate Suppliers are obliged to cancel 010 CoS’s

submitted after day 19 for MPRNs on the day 1 CSV file– Alternate Suppliers will not receive Customer Name for

domestic MPRNS (existing market rules).– Meter Work service orders to be analysed case by

case.– All 010 messages for SoLR MPRNs to contain the new

SoLR Read Arrangement Code.– Analysis work and actions will be carried out by MRSO

and ESB Networks on MPRNs with certain statuses.


Market Change RequestDR 0113 Supplier of Last Resort Update

New Working Practice• A new working practice will be initiated from this DR to provide guidelines on how to handle:

– Disputed reads– Inaccurate / poor estimates readings (e.g. withdrawals, present < previous)– Meter works


Next Schema Release

• June 2008

• Prioritised MCRs/DRs:– DR 117 – Meter Works status message– MCR 0063 – Aggregation Reconciliation Data– MCR 0127 - Decouple CA and CoS

• SoLR Read Arrangement code value

Status: • No impact as MCRs are not complete. Need to

complete rapidly to facilitate development.


Next Steps
