Anglesey has its mandate. On 13 November 2025, Great British Energy – Nuclear confirmed Wylfa as the site for the UK’s first small modular reactors, with a programme designed to deliver up to 1.5GW of low‑carbon power and create thousands of jobs. Today’s December edition of The Spark pulls the strands together for readers following the project’s progress.

The leadership to deliver it is now in place. Simon Bowen was announced as GBE‑N Chair on 13 November, and on 8 December the organisation named energy veteran Simon Roddy as Chief Executive, who takes up the role on 2 March 2026. The pairing signals a shift from site acquisition and technology selection to delivery and accountability.

What will be built first is clear: three Rolls‑Royce SMRs at Wylfa, each around 470MW, with scope for further units subject to contracts and consents. Rolls‑Royce says deep collaboration with the Ynys Môn community is the first priority as supply chains and training pathways are assembled. The Welsh Government has also flagged potential for up to five additional reactors in time.

Regulation is running in parallel. The Rolls‑Royce SMR design entered the final Step 3 of the UK’s Generic Design Assessment in August 2024, with a decision due towards the end of 2026. That process does not replace site‑specific permissions, environmental permits and community consultation, but it is a necessary gateway for safe deployment.

Why this matters for climate is straightforward: nuclear’s full life‑cycle emissions are very low. A United Nations Economic Commission for Europe assessment finds nuclear typically at 5.1–6.4 gCO2e/kWh, comparable with wind and below most solar ranges, supporting a cleaner power mix when paired with demand‑side savings and renewables.

The IPCC’s latest mitigation assessment underlines that reaching net zero requires a largely zero‑carbon power sector with clean firm capacity alongside renewables. In practice, that means projects like Wylfa helping reduce gas dependence while the UK accelerates wind, solar, storage and efficiency.

Jobs and skills are a near‑term prize. Government estimates point to up to 3,000 roles at peak construction in Wales, with long‑term careers on site and across the supply chain. GBE‑N has already launched its Early Careers Programme with Energus and Cogent Skills, bringing graduates and apprentices into post from September 2025.

For people in North Wales, the next year is about tangible engagement. Rolls‑Royce and GBE‑N stress ongoing community dialogue, bilingual updates such as Y Sbarc/The Spark, and clear routes for residents and local firms to feed into procurement and skills offers. Trust is built early and maintained through transparent milestones.

Delivery still has tests to pass: final contracts, the generic design decision, and site‑specific planning and permits. The UK’s aim is to see SMRs operating in the 2030s; meeting that aim will depend on steady regulatory progress and predictable financing that keeps benefits rooted in local communities.

Zooming out, the Wylfa plan sits within a broader public‑ownership push to speed clean power. Great British Energy’s five‑year strategy targets 15GW of generation and storage by 2030 with public investment crowding in private capital; the nuclear arm’s programme complements that by providing dependable low‑carbon output to stabilise the system.

Eco Current will track three signals of success: how fast early careers convert to local, lasting jobs; how clearly regulators communicate each step; and how benefits flow to households via lower wholesale volatility as clean, domestic power grows. If Wylfa delivers on those fronts, it strengthens the UK’s climate and energy security story.
