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.

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))

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

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
