CX Technology Campus Chapelcross Data Centre 1GW Scotland

Status: Announced / In Planning (Planning Permission in Principle Application Submitted)   |   Location: Former Chapelcross Nuclear Power Station site, B722, near Annan, Dumfries and Galloway DG12 6RF, Scotland, United Kingdom

Project Overview

The CX Technology Campus at Chapelcross is a proposed £16.5 billion digital infrastructure development planned for the 500-acre site of the decommissioned Chapelcross nuclear power station near Annan in Dumfries and Galloway, Scotland. Submitted by developer CX Tech Limited through a Planning Permission in Principle application to Dumfries and Galloway Council, the project aims to establish one of Europe’s largest AI and cloud computing campuses. Its scale and focus on advanced computing reflect the growing demand for infrastructure capable of supporting artificial intelligence, hyperscale cloud platforms, and increasingly data-intensive digital services. By repurposing a former nuclear power station site, the proposal also places large-scale technology development within an existing industrial location.

The planned campus is intended to accommodate extensive computing infrastructure for AI and cloud workloads. These applications require significant processing capacity, dependable power supplies, and supporting systems designed to maintain continuous operations. A development spanning 500 acres offers substantial space for multiple data center buildings and associated infrastructure, although the project’s specific IT capacity, power allocation, cooling design, and energy sourcing arrangements have not been provided. The proposed investment of £16.5 billion highlights the scale of the development ambition, but its ultimate capacity and delivery will depend on planning decisions, infrastructure requirements, and subsequent project stages.

The Chapelcross site’s industrial history provides an important context for the proposal, which would transform the former power station location into a major digital infrastructure campus. If delivered as envisioned, the development could expand Scotland’s role in the European AI and cloud computing market while attracting significant investment to Dumfries and Galloway. However, the project remains proposed, with a Planning Permission in Principle application submitted to the local council. Its development timeline, final specifications, and operational arrangements have not been confirmed in the supplied information. The CX Technology Campus at Chapelcross therefore represents an ambitious proposed addition to the UK’s digital infrastructure pipeline, with its eventual significance dependent on planning approval and implementation.
