Enhanced Energy Reconciliation System for Efficient Point Metering

The Individual Meter Point Reconciliation system calculates actual energy use at the meter point level, allowing precise site reconciliation. It incentivizes shippers to obtain reads with transparent supporting data. Developed to aid competition, the system addresses energy misallocations, supports reform, and ensures precise settlement arrangements. Benefits include certainty for shippers, reduced risk, and improved data quality. The implementation timeline encompasses a review in 2007 leading to Ofgem's determination in Q1 2008. Issues to consider include modeling, cost allocation, funding, resistance, timing, shipper targets, reconciliation periods, settlement impact, and data aggregation strategies.

  1. Individual Meter Point Reconciliation

  2. What? • Calculation of actual energy used at meter point level for all supply points • Allow sites to be accurately reconciled • Incentives on shippers to obtain reads • Transparent supporting data

  3. Why? • RbD was essentially an interim step to enable competition amidst data, process and system limitations • RbD works with one dominant shipper, however, there are now six shippers with large RbD portfolios • Approx 400TWh of unreconciled energy p.a. • Huge potential cost misallocations • Support for reform from RbD shippers • The industry has evolved, as has technology, no excuse for acceptance of imprecise settlement arrangements • UK Link replacement system due in 2012 • Electricity has worked for almost a decade ???

  4. When? • Jul ’07 – Review proposal to Panel • Aug ’07 – Initial review group meeting • Oct ’07 – Report to Mod Panel • Nov ’07 – Raise mod & consultation • Jan ’08 – Panel recommendation • Q1 ’08 – Ofgem determination

  5. Benefits • More certainty for RbD shippers • Incentives to get meter readings • Less potential for ‘gaming’ on AQ review • Smaller AQ review process • More correct cost allocation to shippers • Improved data quality • Will emphasise extent of other ‘leakage’ points and increase incentives on market to address • Reduced risk for RbD shippers • Incentives for smart metering

  6. Issues • Type of Model – LSP / electricity / other • Establish an accurate view on costs • Funding arrangements • Resistance from neutral participants • Timing • Shipper performance targets • Reconciliation periods • Impact on settlements • Data aggregation • Inclusion of IGT meter points
