The UK has cleared five 'AI growth zones' for 500MW AI datacentres by 2030. Documents from the most recent one suggest the plans were waved through without the land, power, or grid to deliver them.
When the UK cleared its fifth AI Growth Zone, in Lanarkshire east of Glasgow, the site developer DataVita told the public the datacentre campus would run entirely on on-site renewables, with no connection to the electricity grid. Internal documents reviewed by the Guardian show the same company privately admitted the campus will plug into the grid. DataVita also controls roughly a tenth of the land the scheme requires.
Lanarkshire is the most recent of five "AI Growth Zones" the UK government has cleared, and the first one for which a detailed site record has emerged. The policy, formally opened for applications on the gov.uk portal in late June, is meant to be the centrepiece of Britain's industrial-AI push: 500MW-plus datacentre complexes, larger than any operating in the UK today, sited on former industrial land and wired into a national race for compute capacity. The Department for Science, Innovation and Technology has set 2030 as the delivery deadline.
The gap between those targets and the Lanarkshire engineering record matters because the same clearance template is being applied to the other four zones, including the Stargate UK site at North Tyneside near Newcastle. Documents from the consultation that created the policy, CP 1440, frame the strategy as a coordination exercise across planning, grid, and power. The Lanarkshire file suggests that coordination has not yet happened. Computer Weekly, summarising the policy for the trade audience, has read it the same way: a planning exercise first, an industrial-AI policy second.
The renewables pitch was the public foundation of the Lanarkshire designation. DataVita's announcement described a campus that would generate its own electricity on site and need nothing from the National Grid. The Guardian reports that in communications with the Scottish government and the local council, the same company said the opposite: the campus would take grid power during construction and commissioning, and rely on the grid as a permanent backstop once operational. A 500MW datacentre, roughly the continuous draw of a mid-size city, is not a load that on-site renewables can carry in any UK climate. The 500MW figure is the government's stated feasibility bar, not a design choice.
DataVita's footprint at the site covers about a tenth of the area required for the announced build-out, according to the documents. The remaining land is in third-party hands and has not been assembled. A 500MW datacentre is not a single building but a phased campus of buildings, substations, and cooling plant, and the 500MW threshold is meant to be met in stages. On the land DataVita currently controls, the stages do not line up.
The pattern looks similar at the second named site. North Tyneside, east of Newcastle, was promoted as the Stargate UK campus for OpenAI's UK compute build-out. The Guardian reported that OpenAI did not send representatives to visit the site, despite the project's profile. The Department for Science, Innovation and Technology declined to characterise the visit record, and OpenAI has not published one. The Stargate UK brand has carried the heaviest political weight of any of the five zones, and the absence of a confirmed operator presence on the ground shifts the centre of gravity of the policy from private capital to public planning.
A former UK government official briefed on the policy told the Guardian that the plan was "at best unclear and at worst complete bunk." It is the strongest single line of criticism on the public record, and one source's view. Defenders of the policy argue that the application round will surface the engineering detail that the initial designations skipped. The application process opened formally on the gov.uk portal in late June, and CP 1440 sets out what applicants must show.
Whether the five zones can be built to the 500MW, 2030 standard will turn on three things the Lanarkshire documents do not yet show: a binding grid connection date from National Grid ESO, a land assembly plan that closes the gap between the developer's current footprint and the build-out, and a power supply mix that does not depend on unbuilt on-site generation. The next public checkpoint is the first round of applications, opened under the CP 1440 consultation. If the Lanarkshire record is the template, applicants will be measured against engineering commitments the original designation did not require.
