Fuse plans UK data centres to sell its own Nvidia GPUs
What's the deal? UK energy startup Fuse is moving into AI infrastructure, offering single-tenant Nvidia GPUs housed in its own UK data centres. The company has opened early access to compute capacity, listing 15 projects and a 142MW near-term development pipeline.
What's the endgame? Fuse is pitching "sovereign compute" — UK data centres, jurisdiction, and data path, run by a UK company. Its first listed capacity is a 0.7MW cluster of 192 Nvidia B300 GPUs slated for December 2026, followed by a 1,024-GPU B300 deployment in the second quarter of 2027.
What does Fuse do? It is an OFGEMDealroom has a profile for this one. Try Dealroom →-licensed energy supplier serving 450,000 UK homes, with an average annual saving of £270 per customer. The move extends its vertically integrated energy model into compute, pairing power access with GPU supply.
Why now? Fuse earlier said it was moving its own customer-support AI onto Nvidia-powered infrastructure. The data-centre plans mark a more consequential step, building on that in-house compute push.
Update, 2 November: Fuse chief executive Alan Chang said on X that Fuse Compute went from an idea in June to a signed first compute customer in October. He described the timeline: a US trip in June, where every AI company he met had the same problem of finding enough power for compute; two months learning the business; a dedicated team set up in August; and the first cluster due to go live in December. He did not name the customer. At launch, Fuse and its CTO Greg Wilk had described Fuse itself as Fuse Compute's first customer, using the GPUs for its own AI workloads. The launch plan, as reported by City AM and EU-Startups, starts with 128 Nvidia B300 GPUs in December 2026, rising to 1,024 in the second quarter of 2027, followed by 22MW of data centre capacity in late 2027 and 116MW from 2028. Chang told City AM that energy costs are only about 5% of GPU rental revenue, so Fuse's edge is not cheaper power but faster access to it. Pricing has not been disclosed.
What to watch: Owning compute for internal workloads is not the same as becoming a neocloud. The available reporting does not yet establish that Fuse is selling GPU capacity to outside customers at scale, so the "neocloud" label remains an ambition until third-party sales and operating capacity are clear.
The signal: Fuse's move reflects a broader shift in AI infrastructure, where power and grid access matter as much as GPU supply. UK players such as Nscale and Fluidstack are building businesses around securing both — and an energy supplier extending into data centres is a natural fit for that race.
