Potential Causes

Potential causes, or as they known in the Risk Evaluation Register: Risk Factors are the points of failure that could result in erroneous or estimated data entering Settlement.

Elexon has identified a number of typical failure points related to this risk, parties should note the list is non-exhaustive, and not all risk factors are applicable to every role type.

  • Meter reads are not transferred to Data Collector (e.g. Customer, initial, final etc. from Supplier, Licenced Distribution System Operator and Meter Operator Agent)
  • Meter reads are not validated correctly (by the Supplier or DC, or both)
  • DC calculates EAC/AAs incorrectly, including deemed reads (e.g. using incorrect Daily Profile Coefficients)
  • DC does not send energy volumes to Data Aggregator correctly, or at all (e.g. D0019 / D0036 / D0380)
  • Unauthorised changes to Settlement data are made after Final Reconciliation
  • DC does not reprocess Metered data when additional information becomes available
  • Meter Operator Agent does not calculate Complex Site rule correctly
  • HHDC does not apply the Complex Site rule correctly
  • HHDC does not correctly apply Allocation Schedules for Shared SVA Metering Arrangements
  • Failure to install or maintain communications including cost of line installation and lack of interoperability on Change of Supplier
