5. Gas Settlements, Energy Retail Governance Structure – Initial Stage 5 Performance Committee Performance Assurance Panel Report on issues Analysis required Reporting by Xoserve Reporting requirements to be established Performance Committee to be set up Performance Assurance Panel to be appointed and constituted Report on issues Consider anonymous reports Determine implications on industry process and procedures Are the issues “resolvable”? What is the materiality of the issue? Will the issue be resolved without incentive? (possible MOD in progress or system issue that is scheduled to be fixed, maybe through Nexus) Create report to Panel - issues, materiality, possible target/incentives Receive reports Request additional information as necessary Consider materiality, ability to resolve and prioritise, outlining actions Parties can take to resolve Consider where targets/incentives could be applied Either raise a MOD with Performance target and incentives (where necessary) or develop Working Practice and Procedure Process serials to be developed. For example: AQ Review – AQs of 1kWh, unallocated site statuses Meter read submission – meeting UNC requirements Asset issues – incorrect data Reconciliation – timing out of reconciliation, MOD640 sites Opening Meter Readings RGMA – flow and update issues KEEP THE FOCUS ON ESTABLISHING QUICK WINS
