Annual Run Hours Limited De-Rating Factor Consultation for the T-3 2024/25 Capacity Auction

In SEM-18-009, the SEM Committee consulted upon the derating approach for emissions-limited plant, noting the emerging risk of some plant being limited in operating hours due to emissions. In the following decision document, SEM-18-030, the SEM Committee decided not to impose mandatory additional derating for emissions limited plant, but decided to allow market participants with emissions-limited plant, to (voluntarily) DECTOL their plant to reflect the limitation on their run hours.

New factors are now combining to lead the SEM Committee to consider whether a purely voluntary DECTOL based approach is still appropriate for emissions-limited plant, and the consultation attached seeks responses from industry on a number of options, both in the short and long term.

The deadline for submitting a response on the Consultation to the RAs is 19 July 2021 and responses sent to Kevin Baron (Kevin.Baron@uregni.gov.uk) and Billy Walker (Billy.Walker@uregni.gov.uk).
