● Superscale AI campus · Anglesey, Wales

830 MWe AI data centre in Phase 1. c. 3.3 GW on plan.

A consented 2.5 million sq ft compute campus on Anglesey, inside the Freeport and the North Wales AI Growth Zone. A 958 MWe power programme — a signed 210 MWe firm grid tie-in stepping to 390 MWe, an 18 MWe distribution tie-in, and 550 MWe of on-site generation — with sub-5 ms dark fibre to Dublin, Manchester and Cardiff.

Request capacity
  • 210 MWe contracted, plus 180 MWe under the Modification Application — 390 MWe in total
  • A path to 1,000 MWt of gas across the campuses by 2029: 400 MWt confirmed, 600 MWt requires costed reinforcement works
  • 2.5 million sq ft consented under OP/2025/2
  • The campuses lie within the Anglesey Freeport area and the North Wales AI Growth Zone
  • Subsea cable and dark fibre terminating immediately adjacent to the campus
  • Access to renewables, with sea-water cooling under study

958 MWe. Quarter by quarter.

Capacity arrives in steps, each one already contracted, confirmed, or costed but not yet contracted. On-site generation carries the platform from 2027, ahead of the grid tie-in energising in 2028.

The programme
01 · GRID
Grid tie-in
390MWe
210 MWe contracted

A signed bilateral embedded generation agreement at 210 MWe firm, stepping to 390 MWe under the Modification Application. Offer signed and deposits paid.

02 · ON-SITE
On-site generation
550MWe
220 MWe current · 330 MWe costed, not yet contracted

A path to 1,000 MWt across the campuses by 2029: 400 MWt confirmed, 600 MWt requires costed reinforcement works. This is what carries the platform ahead of the grid.

03 · DISTRIBUTION
Distribution tie-in
18MWe
18 MWe subject to SPEN offer and order

A separate substation through the distribution network — the earliest power available on the platform.

Headline path · three phases
Headline path to c. 3.3 GWe
Phase 1 · To 20300.96GWeIn programmeThe 958 MWe programme — grid tie-in, distribution tie-in and on-site generation.
Phase 2 · To 20320.83GWeDevelopmentA further 1,200 MWt of gas (660 MWe), 120 MWe of tidal and 54 MWe of solar, each shown as static equivalent. Additional to Phase 1.
Phase 3 · To 2034c. 1.5GWeDevelopmentSmall modular reactor capacity, offered under private wire. Additional to Phases 1 and 2.

Phase 1 is the programme above. Phases 2 and 3 are additional to it and to each other: each is a development position, none is contracted, and none carries value in the current plan. Gas converts to electricity at 55 per cent on gross calorific value, so a further 1,200 MWt gives 660 MWe. Tidal and solar are shown as static equivalent, not as generated output.

03 · Deployment classes

Six bands. One pennant.

Capacity is offered in standard bands rather than by bespoke quote. Each deployment carries a pennant — C-01 is the first Cruiser — and that identifier follows it through commissioning and every invoice. Halls are built in 10 MW blocks against 15-year leases.

KCorvette
1–5 MW
ProfilePilot / research

Shared hall. The smallest band offered, and the shortest path to first compute.

FFrigate

Multiple blocks within one thermal zone, commissioned and handed over together.

Capacity federated across campuses under a single offtake. Sovereign and frontier-lab scale.

04 · Commissioning

8 months from signature to load.

Every campus runs the same six-gate commissioning programme, witnessed and evidenced at each stage, from signature to handover and into service. You see the same rail we do.

Dublin in 1.8 ms.

Dark subsea and carrier fibre terminates adjacent to the campus — the nearest existing subsea infrastructure is 0.8 km away. Primary and diverse routes reach Equinix MA5, Interxion/DLR and VDC CWL-1 at sub-5 ms round trip, with onward paths to the United States and mainland Europe. The campus benefits from direct access to subsea cable landings connecting Europe and the Americas, positioned at the gateway between Europe and the Atlantic.
