2. Key √ = Agreed for the purpose of Mod Development X = Rejected
? = More work required
Owner = Person to submit proposed solution or discussion starter at next meeting
Owner = Person to submit proposed solution or discussion starter

3. Meter Reads

4. Meter Reads √ ? SB SL Meter Readings will continue to be submitted
Owner
Meter Readings will continue to be submitted √
Acceptances and rejections will be notified to the User as separate data items
Accepted meter reads will be put forward for review
USRVs will be put forward as current practice
To be considered as part of validation ? SB
All NDM meter types will be put forward (except below)
DMs to be considered further SL
Opening read estimate will only be used as opening read for any variance period

5. Consumption Periods

6. Consumption Periods √ SB ? SN Maximum period will be three years
Owner
Maximum period will be three years √
Minimum period will be nine months plus one day SB
Target period will be different for monthly and non monthly:
Monthly will be 50 weeks ? SN
Non-monthly will be 42 weeks
Current backstop will no longer apply

7. Validation Principles

8. Validation Principles
Validation will be able to be systematised √
Current manual validations will be systematised where practicable
The User will be notified of rejection
Reason codes will be issued with rejections
The User may resubmit for the following month
User identifier will allow validation to be overridden

9. Validation Details

10. Validation Details ? SN EL √
Owner
AQ increases of over 500% will be rejected ? SN
May need to reflect AQ band EL
If User resubmits with an identifier it will be accepted the following month √
Negative AQs will be rejected
All reductions (other than negatives) will be accepted

11. Change Threshold

12. Change Threshold √ ? SB X ST
Owner
There will be change thresholds below which changes in calculated AQ will be ignored √
The Small Supply Point Threshold will be [x]% ? SB
The Large Supply Point Threshold will be [y]%
There will be no exceptions to this rule X
Potential zero or smaller percentage for larger EUCs ST

13. Timescales

14. Timescales √ ? AQ updates shall be monthly
Meter readings will be processed on 15th ?
Calculations will take place between 15th and 25th
Users will be advised on 25th
New values will be live from 1st of the following month
There will be no amendment process

15. Appeals

16. Appeals
Owner
Appeals will not prevent calculated AQs going live but the agreed value will apply in subsequent months √
Meter reading data can be changed by:
A replacement read
A more recent read
Appeals will be allowed if User demonstrates:
Meter asset data is erroneous
Incorrect data adversely affects the AQ
There is a manifest change in usage
Need to debate appeal process for SSPs ? SL

17. Monitoring

18. Monitoring
Owner
Statistics will be reported at an industry forum √
Ofgem will receive a reporting pack ? JB
Reports will be produced per User :
Reports to be determined SN
Frequency to be determined
User anonymity will be retained
All

19. Implementation

20. Implementation ? DNs Large Supply Points will be implemented in 2012
Owner
Large Supply Points will be implemented in 2012 ?
DNs
Small Supply Points will be implemented in 2013

21. Threshold Crossing

22. Threshold Crossing ? SB/ SN MJ All √
Owner
LSP will only become SSP or vice versa when the AQ changes by more than [5]% ?
SB/ SN
Mod 0640 replacement required MJ
Mandatory Daily Metering will only apply when the AQ is calculated to be above the threshold for [three] months
All
Site Specific Correction Factors will only apply when the AQ is calculated to be above the threshold for [three] consecutive months
Supply Points will not automatically revert back if AQ reverts √

23. Other Parameters

24. Other Parameters
Owner
AQ will be updated using the revised WAALP at the first accepted meter reading following a change in the Seasonal Normal Composite Weather Variables √
When SNCWV is changed all AQs will be scaled
WAR will be calculated each year at the first accepted meter reading after 31 March
SOQs will be revised when AQ revised
SOQs will be revised to reflect load factor changes (trigger to be determined) ? SB
