1. UNC Modification Proposal 0362
Chris Warner
Network Code Manager

2. Overview of Issue
CSEP NExA (Annex A Part 5) requires iGTs to issues reconciliation volumes (in respect of CSEP Larger Supply Points) to the upstream Distribution Network
CSEP NExA restricts the meter readings that can be utilised for reconciliation to “Valid Meter Readings”
“Valid Meter Readings” (UNC TPD M3.1.4) do not include
estimated (‘notional’) Opening Meter Readings provided by the DN (UNC TPD M3.8.5)
Agreed Opening Meter Readings (UNC TPD M3.8.7)
iGTs and Users have highlighted this as a key reason why there is a lack of reconciliation volumes submitted in respect of CSEP Larger Supply Points.
risks associated with unreconciled energy and Transportation charges

3. UNC Terms for DN Connected Supply Points
“Valid Meter Readings” (UNC TPD M3.1.4) do not include
estimated (‘notional’) Opening Meter Readings provided by the DN (UNC TPD M3.8.5)
Agreed Opening Meter Readings (UNC TPD M3.8.7)
However
estimated Opening Meter Readings can be used for Individual NDM Reconciliation (UNC TPD M3.8.5(a)); and
Agreed Opening Meter Readings can be used for Individual NDM Reconciliation (UNC TPD M3.8.8(c))

4. Proposed Change to CSEP NExA Annex A Part 5
UNC Modification Proposal 0362
Proposes to extend scope of Meter Readings eligible to be utilised to generate reconciliation volumes. In addition to ‘Valid Meter Readings’:
Estimated Opening Meter Readings; and
Agreed Opening Meter Readings
Would be consistent with UNC terms
Proposal was considered by UNC Modification Panel on 17 February 2011
Subject to Self Governance provisions
Referred to Distribution Workgroup

5. Benefits
As at January 2011
3,995 live LSP LMNs
1,569 (39%) with some reconciliation activity
2,426 (61%) with no reconciliation activity
6,159 closed LSP LMNs
3,238 (53%) with some reconciliation activity
2,921 (47%) with no reconciliation activity
How much additional energy / periods could be reconciled if estimated Opening Meter Readings and Agreed Opening Meter Readings could be used for reconciliation?
UNC 0362 would be enhanced by quantification of this benefit
