Nscale’s Loughton AI campus faces reported grid wait into 2030s

Nscale’s planned AI computing campus in Loughton, Essex, faces a reported wait for sufficient grid power that could run into the 2030s. The Morning Intelligence first reported the delay on September 24. The Guardian says UK Power Networks (UKPN) has reportedly told Nscale that sufficient power will not be available until the early to mid-2030s. UKPN declined to comment on the individual project, and no revised connection offer or opening date has been made public in the sources reviewed here.

The big change

• What changed: Nscale planned to deliver the first GPUs for its Loughton partnership with Microsoft in the first quarter of 2027. A reported wait for sufficient grid power into the 2030s puts the timing of that deployment in doubt.
• Why it matters: Nscale says the planned 50-megawatt facility would provide Microsoft Azure services in the UK. If enough power cannot reach the site on the planned schedule, delivery of that Azure capacity depends on an earlier connection or another workable power source. Neither company has announced a revised service date in the sources reviewed here.
• What to watch: A confirmed power arrangement for the initial 50 megawatts and a revised Azure service date would clarify the deployment schedule. Nscale and UKPN have not publicly confirmed the reported grid timetable.

The plan and the reported constraint

In January 2025, Nscale said its Loughton site was scheduled to be live in the final quarter of 2026. Its September 2025 announcement with Microsoft described an initial 50 megawatts of AI capacity, scalable to 90 megawatts, and 23,040 Nvidia GB300 GPUs to be delivered in the first quarter of 2027. Nscale said the facility would support Microsoft Azure services in the UK. Microsoft confirmed the partnership to build a UK supercomputer supporting its services. Neither announcement gives a grid connection date.

The specific 2030s timetable rests on reporting. The Guardian quotes UKPN saying it cannot discuss an individual project. UKPN said many data centres seeking distribution-network connections await work on the wider transmission network before they can operate. Nscale told the Guardian it remained committed to Loughton and was examining on-site generation and ways to accelerate a connection. The report gives no delivery date for either option.

Nscale specified 50 megawatts as the initial facility capacity and 90 megawatts as a possible scale. The public reporting leaves open whether the grid timetable applies to the initial capacity, the full scale or another stage. It also leaves open whether another power arrangement could support an earlier start.

A wider connection problem, with no site-specific remedy yet

Ofgem’s June 2026 update identifies network-build times and non-viable projects in the demand queue as causes of delay for well-progressed projects. Its July consultation proposes fees and milestones to discourage speculative data-centre applications; the consultation has closed and awaits a decision. NESO’s connections timeline describes when categories of revised offers are due, but does not supply a public Loughton connection date.

The reported delay makes the 2027 GPU plan uncertain. A dated connection offer or a confirmed power plan tied to the initial deployment would clarify the schedule.

• The Guardian’s follow-up, September 24, 2026. Attributes the early to mid-2030s timeline to what UKPN reportedly told Nscale, and records UKPN’s refusal to discuss an individual project, its general transmission explanation, and Nscale’s response. It is reporting, not a published connection offer.
