Why is Elexon making this error public?
Elexon’s core role is to ensure that payments for wholesale electricity supply and demand are settled accurately and efficiently.
Elexon implemented Modification P427 ‘Publication of Performance Assurance Parties’ impact on Settlement Risk’ in February 2023. Since then the BSC Panel has the authority to publish details for public notification of EFR status and contribution to risk where a Performance Assurance Party fails to meet a milestone in its EFR plan following escalation to the Performance Assurance Board (PAB).
Elexon and the BSC Panel believe that this additional transparency and accountability will help drive BSC Parties to improve their performance, to the benefit of all electricity customers.
The BSC Panel approved a publication of the information about Tomato Energy’s error at its meeting on 12 December 2024.
