Overview

• EDF cited a series of positive graphite inspections over the past nine months as the basis for the one‑year extensions.
• The decision secures employment for longer for more than 1,000 workers and preserves capacity equivalent to powering over four million homes.
• EDF said the additional year of generation could reduce reliance on imported gas and support the UK’s clean‑power goals.
• Heysham 2 and Torness remain on track to close in March 2030 with no change to their timelines.
• The update coincides with the government’s Sizewell C funding package — 44.9% public stake, Centrica investing £1.3bn for 15%, EDF at 12.5%, alongside La Caisse and Amber Infrastructure — and EDF signalled a potential Sizewell B life extension subject to a viable commercial model.
