Fuse, the London energy supplier valued at $5bn (£3.7bn), has launched Fuse Compute, with its first 128 Nvidia B300 GPUs due online in December and a plan to scale to 1,024 GPUs by the second quarter of 2027.
Fuse was founded in 2022 by former Revolut executives Alan Chang and Charles Orr. It now supplies electricity to 470,000 British households, has raised about €178m ($199m) since launch and reached group-level profitability earlier this year, having reported monthly EBITDA profitability since December 2025.
Fuse Compute is its first commercial AI product. It offers bare-metal, single-tenant Nvidia GPU nodes hosted in UK data centres that Fuse powers itself, with data kept under UK jurisdiction. Reservations opened this week.
The build-out
The rollout runs in four stages. The first 128 Nvidia B300 GPUs are scheduled for December 2026, rising to 1,024 GPUs in the second quarter of 2027. Fuse then plans to add 22MW of data centre capacity in late 2027 and a further 116MW from 2028.
The company says its near-term projects represent about £1bn of UK infrastructure investment and will support 250 construction and operational jobs. It has 142MW of data centre grid connections in its pipeline across 15 projects, plus more than 1GW of planned power generation.
How the build-out will be financed was not disclosed. Neither was pricing; Fuse said contracts will be negotiated customer by customer.
Power, not price
Chang said Fuse's advantage is access to power rather than cheaper electricity. He told City AM that energy accounts for only about 5% of GPU rental revenue, so owning generation would not on its own let Fuse undercut rivals. Instead, he said, having power available means it can stand up data centres faster than developers waiting in the grid queue.
The company says its most recent solar site was built at about 30% below the industry average cost per megawatt. Chang said Fuse would price its GPUs competitively rather than promise to be the cheapest provider.
Why it matters
The launch comes days after Microsoft pulled out of Nscale's planned £2bn AI data centre in Loughton, Essex, after Nscale was told that securing enough grid power could take until the 2030s. The government's Compute Roadmap says the UK will need at least 6GW of AI-capable data centre capacity by 2030, while new sites face waits of up to a decade for a grid connection.
For Fuse's backers, the move adds a second revenue line beyond household energy supply, which has grown from 50,000 homes in July 2025. It also puts the company in competition with better-funded neoclouds. Nscale alone has raised billions of dollars in equity and convertible debt. At 128 GPUs, Fuse's December launch is small next to those players, and the bulk of its capacity will not arrive until 2027 and 2028.
