Deployment of Error Failure Resolution (EFR) against Settlement Risk 008
This is of interest to all Suppliers with Non Half Hourly portfolios
At its meeting on 27 April 2023, the Performance Assurance Board (PAB) approved the deployment of EFR for Settlement Risk 008; the risk that Supplier Volume Allocation (SVA) metered data is not processed or transferred correctly, or is not processed at all.
Deployment of EFR based on performance against materiality threshold
The deployment of EFR will be based on a Supplier ID being above or below its materiality threshold located in its monthly Large Estimated Annualised Consumption (EAC) / Annual Advance (AA) Materiality Report.
This threshold is determined by multiplying market-level error by the Supplier ID’s NHH energy share down to a minimum threshold of 3,300MWh.
When Suppliers would be considered for EFR
Suppliers will be considered for EFR if the total materiality of their unresolved instances of Large EAC / AAs is above their threshold for three consecutive months.
- If the sending of the Instance and Materiality reports for a given month are delayed, and such delays affect the Party’s ability to resolve instances, the following month will be omitted from the three month count and the next month of timely correct reporting sent will be counted instead.
Parties in EFR will be considered for exit following three consecutive months below the threshold.
- If the sending of the Instance and Materiality reports for a given month are delayed, and such delays affect the Party’s ability to resolve instances such that it breaches the threshold, this month will not be considered as having broken a run of consecutive months below the threshold
Contacting Suppliers that are currently above the threshold
Elexon will contact those Suppliers that are currently above the threshold for the March reporting period shortly after the sending of the April 2023 Materiality Reports, to confirm that two further months above the threshold will mean they will be assessed for EFR.
