Dispute Decisions

We assess all Trading Disputes (Disputes) against the three criteria that must be met. We send our view to the Raising Party and any affected Parties. The Trading Disputes Committee (TDC) hears all Disputes that we think are valid.

ELEXON Trading Dispute Decisions


Disputes that we think are invalid can be closed without being heard by the TDC. However, this is only if, within 14 days of our decision:

  • The Raising Party doesn’t object to the findings
  • No affected Parties object to our findings
  • No other Parties have contacted us to state that they believe they are an affected Party but weren’t informed of our findings.

If you don’t notify me, how can I know whether I’m affected?

The spreadsheet below lists our findings for recent Disputes. If a Dispute is invalid and you haven’t been contacted as an affected Party but believe you should have been, you can contact us via disputes@elexon.co.uk and we will take the Dispute to the TDC.

Register of TDC Determinations


The Register of Determinations is a document which contains all of the Disputes which were upheld by the Trading Disputes Committee (TDC) for the TDC meetings.

It is used to track decisions made and agreed by the TDC for each Dispute which has been presented for the relevant TDC meetings.

It contains information on Disputes such as Dispute reference, raised/end date, materiality, settlements errors and root causes. This document is updated and published on the ELEXON website every 5 working days after the TDC meetings.

EAC/AA Finding Forms

Every month, the TDC authorises the correction of data in the Non Half Hourly market to resolve errors associated with erroneous large Estimated Annual Consumptions (EACs) and Annualised Advances (AAs) in the Post-Final Settlement Run. A Finding Form is issued each month setting out the TDC’s decision.
