1. DM Elective Transfer Scenarios 26 February 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
For DMM/V/E – NDM Transfers the DM estimate will be loaded to create the Transfer Read.
If Outgoing Shipper disagrees with ‘Transfer’ Reading (whether Actual or Estimate), a Consumption Adjustment is required
Incoming Shipper will be required to raise SAR/Consumption Adjustment.
As per Shipper Agreed Reads process where a CA is received around transfer the CA is assumed to be agreed with Shipper A.

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

7. 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
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
