Trading Disputes and Decisions

Trading Disputes provide a mechanism for correcting identified Settlement Errors. It allows for energy that was incorrectly calculated to be re-calculated, and the corrected Trading Charges distributed accordingly. 

The Trading Disputes Committee (TDC) hears all Disputes that we think are valid.

How it relates to you

Trading Dispute: trading charges

A Trading Dispute can arise when errors in the data, processes and/or rules used for the purposes of Settlement affect Trading Charges paid to or from Parties.

Any BSC Party can raise a Trading Dispute.

If you have Category O authorisation (see BSCP38 ‘Authorisations’) you can raise a Trading Dispute by completing a form in BSCP11 ‘Trading Disputes’ and sending it to us with supporting information, e.g. Data Flows, Bid Offer Acceptances or consumption information.

Trading Dispute: credit default

Trading Disputes can also arise as a result of errors in the determination of whether a Party is in Credit Default.

Manifest Errors

A generator or National Grid can claim a Manifest Errors where a Bid or Offer was accepted in error.

The TDC makes determinations on Manifest Errors (see BSC Section Q7) which are processed in accordance with BSCP14 ‘Processing of Manifest Error Claims’.

Q8 Claims

You can claim for unavoidable and material losses incurred as a consequence of not being able to communicate Physical Notifications to National Grid during unplanned outages by National Grid.

The Q8 committee is an extension of the Trading Disputes Committee (TDC) and hears trading compensation claims. The same members who sit on the TDC also form the Q8 Committee.

Process

ELEXON manage the process and investigate the Trading Dispute in consultation with any relevant Parties, Agents and/or experts.

Trading Disputes is a remedial technique in ELEXON’s Performance Assurance Framework.

We assess all Trading Disputes against the three criteria that must be met. The results of our assessment are sent to you (the ‘Raising Party’) and any other affected Party.

Criteria

  • Timeliness (was the Dispute raised within the timescales set out in BSCP11?)
  • Settlement Error (was there an error in the data and/or processes used for Settlement arising from a failure to follow the provisions of the BSC such that the error affected Trading Charges?)
  • Materiality (was the effect on Trading Charges greater than £3000?)

Invalid Dispute

If we believe the Trading Dispute is invalid and you as Raising Party are happy with the findings then we will close the Trading Dispute.

If you disagree with us finding the Trading Dispute invalid we are able to refer the case to the Trading Disputes Committee (TDC) for consideration.

Valid dispute

If the Trading Dispute is valid, we will take it to the Trading Disputes Committee (TDC) who will assess the dispute. 

We notify the Raising Party and affected Parties of the TDC’s decisions after the meeting. The Raising Party or any affected Party has the option to attend the Trading Disputes Committee meeting where the Trading Dispute will be heard.

If the TDC doesn’t reach a majority decision or a Party disagrees with the TDC decision, the TDC or the Party can refer the matter to the BSC Panel

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

Being notified

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, please contact us 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) at its meetings.

It contains information on Disputes such as Dispute reference, raised/end date, materiality, settlements errors and root causes. It is used to track decisions made and agreed by the TDC for each Dispute when it has been presented at the relevant TDC meeting.

This document is updated and published on the ELEXON website every 5 working days after the TDC meetings.

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.
