CP1545 ‘Introducing Technical Assurance of Metering (TAM) Central Volume Allocation (CVA) Specific Sample audits’

Formal title: Introducing Technical Assurance of Metering (TAM) Central Volume Allocation (CVA) Specific Sample audits

Elexon is currently only able to conduct Specific Sample Audits on Supplier Volume Allocation (SVA) sites, which limits our ability to assure the integrity of Settlement across Central Volume Allocation (CVA) sites.

The Technical Assurance of Metering (TAM) Performance Assurance Technique (PAT) monitors compliance of Metering Systems against requirements in the BSC and its subsidiary documents. It comprises of a combination of on-site Inspection Visits and remote Desktop Audits, on Half Hourly (HH) SVA and CVA Metering Systems.

The Performance Assurance Board (PAB) have the option to request a Specific Sample through the TAM, which focuses on an area of perceived risk to Settlement. However, we are currently only able to undertake a Specific Sample on SVA Metering Systems, which limits our ability to provide targeted Assurance on CVA Metering Systems.

The solution is to remove the ‘SVA only’ clause from BSCP27 ‘Technical Assurance of Half Hourly Metering Systems for Settlement Purposes’.
