  1. Datalogger / DMV Modification Proposals - Summary Simon Trivella – 24th June 2010 Distribution Workstream - Elexon

  2. Background / Drivers • The world is changing – increase in AMR usage and new supplier obligation increases the number of devices attached to meters • More options for obtaining data • More cases of devices being disconnected resulting in lost data and therefore data not being usable • DM elective (DME) due to be introduced in November 2010 • Consistent with meter reading being a competitive activity • Modification Proposal 0258 already implemented which reflects this changing world • Allows Transporter to procure data from 3rd parties

  3. Background / Drivers • DM Unbundling to be considered / developed • Potential lengthy timescales • WWU is drafting three Modification Proposals • Priority of position for Transporter equipment • Removal DM voluntary (DMV) sites from DM liability regime • Removal of DMV regime when DME is operational and after transition period • Detailed discussions to take place at June 2010 Distribution Workstream • Feedback / comments welcome in the interim period

  4. Priority of position for Transporter equipment • Gives priority of position to Transporter dataloggers and data recorders installed for UNC purposes • UNC refers to IGE Meter Recommendations • Installation of Supply Meter only • IGEM/GM/7A proposes that loggers used for fiscal purposes should have priority • This does not apply to equipment used for other purposes (e.g. Demand Estimation) • We recognise work to develop standard MPU contract • For historical reasons Transporter equipment tends to have priority of position • Modification raised to regularise situation and ensure that the position is clear within the UNC

  5. Removal DM voluntary sites from DM liabilities • DMV sites can be from 73,200kWh to 58,599,000kWh • Not material to daily balancing requirements • Daily settlement data requirements are D+5 • Removal of DMV from DM liability regime would mean that networks concentrated on the DMM sites that are material to daily balancing

  6. Removal of DMV regime • Once competitive activity established then the bundled service should cease to be an obligation • Transporters could act as a DM(E)SP (outside of UNC arrangements) • Consistent with meter reading being competitive activity • DM elective will provide competitive alternative to DMV • Phased approach consistent with DME rollout • Transition period of [3] months following each Phase • 1st Phase transition period of [6] months • After transition period all DMV sites become DME or NDM

  7. Next steps • Comments / Feedback welcome • [Draft] Modification Proposals raised in June 2010 • Further Discussion / Development at June 2010 Distribution Workstream
