Nscale Loughton AI Data Center Delay: Grid Power Slips to 2030s
Published by AINave Editorial
Nscale’s planned AI data center in Loughton, Essex, has a constraint that money and GPUs cannot solve on their own: electricity. The site was set to launch in 2027, but UK Power Networks told Nscale the grid would not provide enough power until the early 2030s. That shifts the project’s expected power availability by years, without establishing a firm revised opening date.
The timing is especially stark because the site was still operating as a scaffolding yard in March 2026, according to TechRadar. The project had also been cited by former UK prime minister Keir Starmer as part of the country’s AI strategy. Those details sharpen the contrast between a national AI ambition and the practical infrastructure needed to make one facility run. The report describes Loughton as the UK’s largest AI supercomputer project.
Why Loughton needs a major grid connection
The facility requires 90MW to operate, which TechRadar compares with the electricity use of 315,000 homes. Nscale’s planned neocloud is a GPU-based AI cloud data center, and the report says it cannot operate without that supply. In other words, the connection is a prerequisite for the planned facility, not a minor operational detail that can be added after launch. The site’s stated power requirement is 90MW.
Nvidia is among Nscale’s backers, but the obstacle described for Loughton is the timing of adequate grid power. The evidence does not identify a shortage of GPUs or funding as the reason for the delay. Hardware investment and site construction cannot substitute for a connection capable of delivering the required electricity.
Loughton sits inside a larger connection queue
The UK-wide figures help explain why this is more than a site-specific scheduling problem, while not predicting the outcome for every project. Ofgem figures cited by TechRadar show that, in June 2026, 315 data centers were awaiting connection, representing 73GW of demand. The report compares that with UK capacity of 45GW, making queued demand 62% higher. Those figures describe the national queue, not a guarantee that all projects will be built.
That context makes the Loughton delay a useful reminder about AI infrastructure: a planned compute cluster only becomes an operating service when the surrounding systems can support it. For this project, the published milestone is when sufficient grid power may become available, not when the data center will definitely open.
