Performance Assurance: Risk Evaluation Register

The Risk Evaluation Register (RER) sets out the Settlement Risks that have been identified and evaluated by reference to classes of Performance Assurance Party (PAP) rather than to a particular PAP. 

How it relates to you

Settlement Risks relating to Supplier Volume Allocation, Central Volume Allocation and Central Systems processes fall under the scope of the RER.

The RER explains the annual process of review whereby existing risks are amended and/or new risks included. 

A Settlement Risk is a risk of any failure or error in a process required under the BSC that may impact (or has impacted) Settlement. Settlement Risks are recorded on the Risk Evaluation Register (RER).

An example of a Settlement Risk description from the RER is:

“The risk that [the NHHDC does not enter valid Meter readings by the Final
Reconciliation (RF) Settlement Run] resulting in [old/default data entering
Settlement]”.

Elexon review the Risk Evaluation Register (RER) annually, as required in the Balancing and Settlement Code (BSC) section Z5.5.3.

Elexon use the approved Risk Evaluation Methodology (REM) to identify and evaluate the Settlement Risks.

The PAB consults with stakeholders on the Settlement Risks, before approving the register for use.
