3. Transfer issues with new Regime
Read obtained 5 days either side of the transfer date may not work for sites where daily reads submitted.
Obtain read on the transfer date?
Deadline for submission of the transfer read required to ensure any subsequent reads loaded are processed
Apply a D+5 close out for submitting a valid transfer read for Processes 3 & 4?
Where a read is not loaded GT estimates on D+5
Processes 1 & 2; no issue as a read is received/loaded by D+5
Deadline for the Outgoing Shipper to submit their ‘normal’ reads?
Processes 3 & 4 only. Impacts if reads not received?
Change of regime to Processes 3 or 4; should a batch of reads or periodic read only be accepted after a valid transfer read is loaded or at [D+6] (estimate submitted by GT)?
The transfer read process must also be appropriate for dumb metered sites

4. GT estimate issued where a valid transfer read
Ideal Solution: Shipper & Regime Transfer all Processes (except Dumb sites?)
