Government Response: Alternative OPZ arrangements and REPPIR19 reform

Policy delivery is already underway. Experts have identified alternative OPZ arrangements, and options are being prepared for both GW-scale and SMR/AMR reactors. The Government will amend REPPIR19 and introduce an appeals process for disputed DEPZ determinations. This aligns closely with the Taskforce recommendation and demonstrates that technical groundwork has progressed ahead of the formal response, giving confidence in the December 2026 delivery timeline.
