Datalogger / DMV Modification Proposals - Summary

• Simon Trivella 27th May 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

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

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 D5
• 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

Next steps

• Comments / Feedback welcome
• Draft Modification Proposals raised in June
  2010
• Further Discussion / Development at June 2010
