Microsoft's decision to pull the plug on its anchor AI data centre deal with Nscale has thrown fresh light on a less glamorous but critical piece of the story: the UK's power grid. While neocloud operators fight for funding and contracts, electricity networks and equipment providers still control the literal on switch for AI. This piece walks through three UK Power and Grid Infrastructure Enablers exposed to that shift and why they deserve a closer look right now.
The stocks covered below are just a starter pack for thinking about UK grid exposure. The full screen surfaced 26 more companies with equally detailed stories that are not covered here. To go beyond this short list, head straight into the UK Power and Grid Infrastructure Enablers for Data Centres screener to analyze, filter, and identify your own highest conviction power grid enablers for data centres.
Overview: Drax Group is a major UK renewable generator supplying large scale, dispatchable low carbon electricity and grid support services that data centre operators increasingly depend on.
Operations: Drax Group generates about £4.1b from Biomass Generation, £2.4b from Energy Solutions and £0.8b from Pellet Production, with most revenue earned in the United Kingdom.
Drax Group matters for this screener because it couples big grid connections with power assets that can flex around the stop start needs of energy hungry AI workloads.
"The build out of over 700MW of battery storage, supported by around £500m of committed capital and the Flexitricity optimization platform, creates scope for Drax Group to scale BESS system services income well beyond the £50 to £100m EBITDA contribution already included in 2029 guidance, which could lift long term margin mix."
What happens to that potential will depend heavily on how one less visible pressure reshapes the economics of keeping these assets online.
That pressure point is exactly where the full narrative for Drax Group joins the dots on policy risk, capital spend and how Drax Group's grid role could keep evolving in an AI hungry world.
Overview: Volex supplies power and high speed connectivity products, including data centre power cables, to keep AI compute and grid linked systems running.
Operations: Volex generates about $158 million in Asia, $439 million in Europe and $646 million in North America, showing a broadly diversified footprint.
Volex matters for this screen because it sells the heavy duty cabling and assemblies that turn new AI data halls and substations into working assets.
"Rapid build out of AI and cloud infrastructure is supporting demand for high speed copper data interconnects. Volex is already supplying up to 800 gigabits per second products to major data center customers, which directly supports revenue growth and a richer product mix that can underpin operating margins and earnings."
What that means for future profitability depends on how a relatively quiet shift in customer buying behaviour reshapes the mix of projects Volex wins.
That shift in buyer behaviour is exactly where the full narrative for Volex shows how Volex's AI data centre exposure, pricing power and risks could be pulling in different directions.
Overview: Invinity Energy Systems designs and sells grid scale vanadium flow batteries that store electricity for utilities, data centres and industrial users.
Operations: Invinity Energy Systems currently generates about £9 million of revenue from batteries and battery systems, its core energy storage activity.
Invinity Energy Systems fits this screen because its batteries operate directly on the grid, helping keep power steady when data centre loads surge or local renewables swing around.
"One key risk stood out, and that is the need for Invinity to maintain access either directly or indirectly to the raw materials required for their batteries, vanadium being of particular importance."
What happens to future project economics may hinge on how a single supply chain pressure shapes long term storage costs and contract terms.
This is where full narrative for Invinity Energy Systems pulls together how Invinity Energy Systems could turn that supply risk into either a catalyst or a ceiling for future grid scale storage demand.
