DATA CENTRES Building data centres off-site
By Michael Beagan, Managing Director of TES Power The Data Centre Industry’s Shift from On-Site Construction to
Off-Site Manufacturing is an Opportunity for Northern Ireland A
s of August 2025, the UK data centre pipeline was valued at around £36.4 billion, spanning close to 100
developments. Much of this activity is being driven by the need for infrastructure to support AI workloads, which are expected to add around 6.2 GW of IT capacity to the UK by 2030, more than twice the current UK capacity of 2.9 GW. Meeting the demands of AI data centre growth means learning to design and build for the AI age. The scale, complexity and pace associated with AI infrastructure is reshaping where, how, and how fast digital infrastructure is built. Growth is being encouraged at the national policy level, with the government establishing AI growth zones across the UK, designed to accelerate planning approvals, improve access to power and attract investment. At the same time, grid constraints, land costs and the lower latency sensitivity of AI workloads are pushing development beyond established hubs such as London. However, building larger and more complex facilities in less established regions presents challenges, particularly around labour availability, delivery timelines and construction risk. It also creates opportunities for regions with strong manufacturing capabilities, including Northern Ireland.
The increasing scale of AI deployments, combined with tighter timelines, means the next generation of digital infrastructure will be built in a different way. Modular, pre-engineered assemblies can support faster deployment, more consistent quality and more reliable performance. They also allow operators to scale capacity in a more controlled and predictable way. Historically, construction involved multiple
trades working simultaneously on-site, often leading to coordination challenges. Today, elements of this process are being moved into controlled manufacturing environments, where critical infrastructure components are designed, assembled and tested for consistency and precision. Modular, pre-engineered power pods are gaining traction as part of this shift. This approach enables faster deployment, improved consistency and more predictable performance. It also makes it easier to deliver projects at the pace demanded by the AI boom, aligning build-out with demand.

recent years. While modularisation was once considered a niche solution for edge data centres and disaster recovery, it is now being adopted more widely across parts of the data centre market, including larger-scale developments. Critical infrastructure components including
power, cooling and UPS, can now be fully assembled and tested prior to delivery. This allows for tighter quality control, reduced reliance on on- site labour, and the ability to test systems earlier in controlled environments. Power Pods can undergo Level 1 and Level 2 Factory Acceptance Testing (FAT) before they are shipped, which reduces on-site installation time, helps shorten project timelines and lowers risks. Northern Ireland’s manufacturing sector offers a compelling combination of advantages. The region’s strong industrial heritage in areas like Mid Ulster and the North West, where clusters developed over decades. This provides both the infrastructure and skilled workforce required to support high quality, precision led production. Northern Ireland’s unique trading posting
offers a strategic advantage. Under the Northern Ireland Protocol and the Windsor Framework, goods produced in Northern Ireland can move with relative ease between the EU and the UK,
free trade agreements. This dual market access can help reduce the administrative complexity of cross- manufacturers targeting multiple markets. For companies involved in data centre supply responsiveness to demand across the UK and Europe is invaluable. As modularisation becomes the solution to data centre construction challenges, Northern Ireland is well placed to address the related challenge of manufacturing and transporting complex infrastructural components within the regulatory landscape of a post-Brexit Europe, and an increasingly strained global supply chain. As the industry evolves to meet the demands
of AI, the way data centres are delivered is becoming more industrialised, with a growing role for off-site manufacturing and modular assembly. This shift places greater emphasis on regions that can deliver precision manufacturing at pace, Northern Ireland is well positioned within this landscape, with its manufacturing expertise, skills base and trading access, all factors that play a data centre development.
