  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 • As a guide, Xoserve is identifying volume of online reconciliation using the two read types
