Objectives for Today’s meeting
• Review ‘As-is’ iGT process for MPRN creation,
set up & initial Shipper registration
• Review Strawman processes
• Agree requirements
• Agree plan for next meeting
Key aspect of current arrangements and
possible changes with Nexus solution
• CSEP set up is a two stage process;
– GT notifies Xoserve of CSEP creation
– iGT submits nomination file in respect of shipper confirmation on
the CSEP
• Issue:
– Timing of notification by GT can lead to shipper confirmations
with iGT before set up in Xoserve
• Current arrangements use aggregated values for SSP and
individual values for LSP within a CSEP
• Issue:
– The LMN for the aggregated shipper SSP portfolio and individual
shipper LSP is not efficient
7
Key aspect of current arrangements and
possible changes with Nexus solution cont.
• For SSP sites within a CSEP a Shipper “bulk” confirms
with the iGT
– Process is initiated by the iGT
– This process to continue under Nexus for the initial
registration of new meter points
• For LSP sites within a CSEP shipper confirms at meter
installation
• The Nexus solution will be to hold every supply point at
individual MPRN level
