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
7Key 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
8Key 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
