Ofgem's determinations on Tier 2 Capacity Market disputes: Delivery Year 2024 to 2025
Summary
Ofgem determinations on Tier 2 Capacity Market disputes for Delivery Year 2024-25. Tier 2 disputes are appeals against Capacity Market decisions on individual CMUs (Capacity Market Units).
Why it matters
Annual dispute determinations are a window onto specific CMU controversies. Outcomes set precedent for how the Capacity Market treats edge cases (de-rating, refurbishment, longer-duration storage participation). Reading them tells you what the CM is wrestling with on the margin.

If an applicant disagrees with the Delivery Body’s decision, it may ask the Delivery Body to review it – a Tier 1 dispute. Following a Tier 1 review, the appellant can ask us to consider the Delivery Body's decision and make a determination – a Tier 2 dispute. Our review considers whether the Delivery Body had applied the Capacity Market Regulations and Capacity Market Rules correctly when making its decision, based on the evidence before it when it did so. We have a duty to publish our determinations in respect of Tier 2 Capacity Market Disputes.
