Ofgem, GB’s National Regulatory Authority, has rejected the proposal to continue with Capacity Market payments using a temporary scheme as per “notice P378” for now. This is because Ofgem do not believe they have the power to make the modification to the Balancing and Settlement Code as outlined in P378. The decision notice can be found here.
In parallel, the European Commission has opened a detailed investigation into the scheme, as announced in this press release. The Commission, who were supporitve of the market design to begin with, are required to continue with this, despite also appealing against the ECJ decision.
