Microsoft exits UK AI data centre plans at Nscale’s £2 billion Loughton site in Essex, after power grid delays pushed the expected electricity connection into the 2030s, raising questions about the project’s timeline.
Power Delays Disrupt Plans for Major AI Facility
Nscale, a data centre infrastructure company, said it remained committed to developing the Loughton site despite Microsoft’s departure. The project was announced last year and was expected to become one of the United Kingdom’s largest facilities dedicated to AI computing.
The BBC reported that Microsoft, which had planned to fund a supercomputer at the site, had terminated its involvement. Nscale had expected the facility to receive its power supply by the end of 2026, but the connection is now not expected until the 2030s.
The delay presents a major challenge for a project that depends on substantial and reliable electricity supplies to operate advanced computing infrastructure. AI data centres require significant power to run servers and cooling systems, making access to grid capacity a key factor in their development.
Nscale said it was investigating alternative energy sources and additional UK expansion sites. The company did not announce a revised opening date for the Loughton facility.
Nscale Seeks Alternative Power Sources
“We remain committed to both the Loughton project and the UK, and we are exploring alternative power sources for the site, in addition to other expansion sites in the UK,” an Nscale spokesperson told the BBC.
The company also sought to distinguish the setback from its wider relationship with Microsoft. “Our relationship with Microsoft remains strong and long-term,” the spokesperson said, adding that the London-area grid issue did not affect Nscale’s other contracts.
Microsoft declined to comment on its withdrawal from the Loughton project. However, the two companies continue to work together on projects in Norway, Portugal and the United States, according to the BBC.
The departure marks a change in plans for a project previously linked to Microsoft’s broader UK investment commitments. Last month, Microsoft announced that part of its planned $30 billion investment in the country would support the Loughton supercomputer.
The latest development leaves Nscale responsible for finding a viable path forward for the site, including securing a suitable power supply and determining how the project will proceed without Microsoft’s planned involvement.
Project Promises Jobs as UK AI Investment Continues
Despite the uncertainty, the proposed data centre is expected to create about 250 permanent jobs once it opens. The delay, however, could postpone those employment opportunities and the wider economic benefits associated with the facility.
The project highlights the infrastructure challenges facing companies seeking to expand AI computing capacity in the UK. Investment commitments alone cannot ensure that large-scale facilities become operational when electricity connections and other essential infrastructure are delayed.
For Nscale, identifying alternative power arrangements will be central to maintaining progress at Loughton. The company has reaffirmed its commitment to the UK, but the revised grid timeline leaves the site’s development schedule uncertain.
The withdrawal does not signal an end to cooperation between Nscale and Microsoft, whose other international projects remain active. Whether Nscale can revive the site after Microsoft exits the UK AI data centre project will depend on the alternatives it secures.
