7. 7 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

8. 8 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
