3 UK Stocks Tied To AI Data Centre Power Demand

AI is hungry for two things, computing power and reliable energy, and Drax Group’s £20bn data centre plan has just thrown a spotlight on both. When money starts chasing new infrastructure on this scale, capital often flows in clumps, not in straight lines. This piece examines what that could mean for UK listed data centre and power businesses and describes three stocks that appear particularly exposed to this news.

The three stocks in this piece are only a sample of the theme, and the full screen surfaced 8 more UK listed data centre and power providers with equally interesting stories that are not covered here. To go wider than this article and identify, compare, and analyze potential high conviction ideas directly, head straight into the AI datacentre infrastructure and power providers screener.

Calnex Solutions (AIM:CLX)

Overview: Calnex Solutions designs and sells specialist test, timing, and network emulation equipment that helps telecoms and data centre operators keep AI era infrastructure running reliably.

Operations: Calnex generates about £21.9 million from electronic test and measurement instruments, with revenue split across the Americas (£6.7 million), North Asia (£3.6 million), and the rest of the world (£11.6 million).

Market Cap: £49.8 million

Calnex Solutions matters for this AI datacentre infrastructure theme because its timing and network test gear helps keep increased capacity stable when operators push networks harder.

Rapid build out of AI driven cloud and data center infrastructure, including new PTP timing profiles and more complex architectures, is expanding demand for Calnex timing and network emulation tools.

What happens to Calnex’s earnings power if a single key assumption about long term demand for this kind of tooling breaks?

That question sits at the centre of the full narrative for Calnex Solutions, which sets out how AI timing demand, margin risk and optionality could be decoupling for Calnex Solutions.

Tritax Big Box REIT (LSE:BBOX)

Overview: Tritax Big Box REIT owns and develops large UK logistics warehouses and land that can host data centres and power hungry AI infrastructure.

Operations: Tritax Big Box REIT generates about £354.5 million from investment in Big Box Assets, all from logistics properties across the United Kingdom.

Market Cap: £4.3b

Tritax Big Box REIT provides AI infrastructure exposure through its UK logistics estates, where power ready land can be turned into hyperscale data centre campuses. The REIT has secured 507MW of power and identified an opportunity pipeline of roughly 1GW. A key consideration for investors is how returns might change if assumptions about the timing or cost of that build out are adjusted.

If that timing on power and build costs is what you are weighing up, the analysis report for Tritax Big Box REIT looks in detail at how Tritax Big Box REIT’s opportunity set could evolve.

SEGRO (LSE:SGRO)

Overview: SEGRO is a UK and European REIT that owns and develops modern warehouses and data centre ready industrial estates near key infrastructure hubs.

Operations: SEGRO generates about £630 million of rental income from investment and trading properties, largely supported by additional service, rent and management fees.

Market Cap: £12.4b

SEGRO matters for this AI datacentre infrastructure screen because its power capable warehousing estates can be shaped into data and edge computing hubs where grid access and location are the scarce ingredients.

The "190 MVA" power reserve, frequently highlighted in reports, is a hidden treasure on SEGRO's balance sheet. Considering the cost and time involved in acquiring a new connection to the London grid, the value of this reserve is far more than just a "permit."

What those locked in power rights mean for SEGRO’s future cash flows depends on how one unseen pressure on returns ultimately resolves.

That pressure point is exactly where the full narrative for SEGRO shows whether SEGRO’s power reserve is quietly compounding value or masking a tougher trade off ahead.
