Catching up: GB TCLC penalty, IOLC and market design (GB/EU)

This is the final “catching up” post following our offline period. The previous post on REMIT can be found here and CBAM/EMIR here.

In Great Britain a generator was asked to pay a penalty of 23.63m GBP for a breach of the Transmission Constraint Licence Condition (TCLC). The notice can be found here. The generator was accused of submitting bids for a reduction in generation when behind a transmission constraint, in a manner that obtained an “excess benefit”, which is prohibited by TCLC. The activity took place between October 2019 and May 2021. The fine follows several in 2023 (for example see here). Recently the “Inflexible Offer Licence Condition” in Great Britain (IOLC) came into force (see here).

Also in Great Britain, Ofgem issued this paper as part of the Review of Electricity Market Arrangements (REMA) which puts forward a view that the wholesale market should move to a locational pricing model. The paper looks at the different options in detail.

The EU Electricity Market Redesign in now in Trilogue (see here for a post from EFET on X). This follows the Council’s stance being published (see here).
