DM Elective Transfer Scenarios 29 January 2009

2 Principles  Incoming Shipper or Read Provider responsible for obtaining read at Start of GFD – i.e. 01/01/09  Where Outgoing Shipper or Read Provider provides reading this will be rejected, regardless of whether Incoming Shipper or Read Provider provides reading  If Actual Reading not provided by Incoming Shipper or Read Provider, Reading Calculated by:  D-7  AQ/365  NDM Estimate Read Process  File to notify Shippers of ‘Transfer’ Readings will be relevant to read service

3 Further Principles  If Outgoing Shipper disagrees with ‘Transfer’ Reading (whether Actual or Estimate), a Consumption Adjustment is required  Incoming Shipper will be required to raise  As per Shipper Agreed Reads process where a CA is received around transfer the CA is assumed to be agreed with Shipper A

4 Discussion Points: Asset Exchanges IDC Changes

5 Discussion Points: Datalogger to AMR kit Exchanges DMSP / IDC Switch

6 Discussion Points: AMR to Datalogger kit Exchanges IDC / DMSP Switch

7 Discussion Points – Read Not Provided: No DM history for D-7, or AQ/365 Previous NDM Readings may be aged Discussion Points – General: Assumes NDM-DM Readings follow on

8 Discussion Points – Transfer Reads (D): DM / NDM Readings may not be in sequence Opening Reading may not get loaded until D+10 Likely to require Manual Intervention Discussion Points – Transfer Reads (>D): DM / NDM Readings may not be in sequence Inferred large consumption for GFD 31/12 Ratchet Functionality? Opening Reading may not get loaded until D+10 Likely to require Manual Intervention

9 Discussion Points – Transfer Reads (<D): DM / NDM Readings may not be in sequence Inferred negative consumption for GFD 31/12 Opening Reading may not get loaded until D+10 Likely to require Manual Intervention
