Summary

This change requires various amendments to the current FSG/GSOP1 service provided by Xoserve.

   - Scheduled payment frequency from fortnightly to weekly.

This would accommodate the reduction from 20 to 10 working days for settlement after an FSG event.

The adhoc FSG process should endure in the event of a major incident.

   - UK Link SAP ISU parameter change.

The current Ofgem level of compensation (£1,000) will no longer be required as the ceiling on payments will be lifted with no upper compensation level required.

   - Removal of the maximum number of days payable to a customer who has been off gas, this will now be unlimited.

   - All GSOP (1, 2, 3,12 & 13) rates of compensation are to be amended yet to be advised by Ofgem.

These changes will require amendments to the validation rules applicable to GSOP1 and the subsequent payment of GSOP12 in the event of a failure to make payments within the 10 working days window.

Consideration any changes within the process required to address iGT customer payments i.e. timescales constrictions, payment recipient iGT or Customer and GSOP 12.

This Change is in scope of Minor Release Drop 9.
