CX Tech says its proposed data-center campus at Chapelcross, Scotland, could reach 1GW of capacity. The company’s filing puts that ambition before planners, but it does not establish that the campus can obtain the electricity, financing or permissions needed to reach that scale. The verdict on delivery is unproven.
The distinction matters because the numbers are substantial: a stated £16.5 billion investment value and a proposed buildout on land north of a former nuclear power station. Neither the price tag nor the location turns a planning application into a funded project.
What has CX Tech actually filed?
CX Tech has applied to Dumfries and Galloway Council for Planning Permission in Principle for the CX Technology Campus. The proposal covers eight data-center buildings and associated development across a 55-hectare site, with construction envisaged in phases from 2027 to 2035, DatacenterDynamics reported. The 1GW figure is the company’s stated potential capacity, not power already available to the site.
A filing is a real planning step. It gives the council a proposal to assess and the public a clearer account of what the developer wants to build. But CX Tech itself says later phases depend on further design, commercial, planning and investment decisions. Permission in principle has been sought, not granted; it would not, by itself, deliver every phase.
There is a credible case for assessing a project of this scale rather than dismissing it because the numbers are large. A phased application can expose questions about land use, infrastructure and environmental effects before construction decisions are made. That is what scrutiny is for. Treating the filing as proof of delivery would bypass the very tests the process is meant to provide.
Where does the 1GW claim meet the power question?
A gigawatt is a measure of power, and CX Tech presents 1GW as the campus’s potential capacity. It says it is exploring connections to wind, solar and biomass generation and describes renewable power as central to its plans. Exploring a connection is different from demonstrating that electricity has been contracted and can be supplied on the proposed timetable. The reported plans do not establish that those arrangements are secured.

The Chapelcross name may invite another mistaken inference. The proposed site lies north of a former nuclear station, but that station was decommissioned in 2004. Its history does not show how much electricity could be supplied to a new data-center campus. An old generation figure or a familiar industrial location cannot substitute for evidence of present-day power arrangements.
The same test applies to money. DatacenterDynamics reports £16.5 billion as the investment value attached to the proposal. That figure describes the project’s stated scale; it is not evidence that £16.5 billion has been committed or that a final investment decision has been made. Nor do the available accounts establish named customers. Before treating the campus as a deliverable investment, readers should expect to see financing and a credible path from each proposed phase to the infrastructure it requires.
CX Tech also projects about 750 construction roles, 540 permanent direct jobs and 40 apprenticeships per construction year. These estimates help explain why the proposal deserves attention. They remain forecasts tied to a buildout whose permissions, power supply and funding have yet to be established, not jobs already created.
What will planning scrutiny establish?
The Scottish Government announced on Sept. 16 that new data-center applications above 50MW must include an Environmental Impact Assessment, a review of a project’s likely environmental effects. CX Tech says one accompanied its application. Submitting an assessment is part of scrutiny, not a ruling that the proposed development’s effects are acceptable.
The political position is also more precise than a blanket ban. Scotland’s Parliament agreed an amended motion calling for no planning or consenting decisions on hyperscale data-center applications until national guidance is complete. The Scottish Government said it did not support a moratorium. The parliamentary call does not prohibit CX Tech from filing an application, and it should not be mistaken for a decision approving or rejecting this one.
Opposition is part of the record, too. South Scotland Green MSP Laura Moodie has argued that the project’s scale risks the energy supply and natural environment. Those concerns deserve examination through the planning and environmental evidence, just as the developer’s claims about renewable power and employment do. Neither concern nor promise settles the outcome in advance.
CX Tech’s filing supports a narrow conclusion: a developer has put a large, phased proposal before the council. The stronger claim—that a 1GW campus can be powered, financed, approved and built on the proposed schedule—remains unproven. Evidence of workable power arrangements, committed financing, planning decisions and independently assessable plans for each phase would change that verdict. The filing alone cannot.
