Microsoft has confirmed that it terminated its agreement to lease capacity at a planned AI data centre in Loughton, Essex, built by Nvidia-backed British start-up Nscale. The facility was meant to house 23,040 Nvidia GB300 GPUs delivering around 50 megawatts of AI compute for Azure in Britain, with Microsoft as the anchor tenant. According to reporting from Reuters and others, electricity grid officials told Nscale they did not expect to supply power to the site until the 2030s, years after the planned opening.
A Microsoft spokesperson said the decision relates to a single site and that the company remains committed to its partnership with Nscale. The two companies continue to work together on projects in Norway, Portugal and the United States. Nscale says it remains committed to the Loughton project and the UK, and is exploring alternative power sources and additional UK sites. The site was expected to create around 250 permanent jobs when it opens.
Power is the new bottleneck for European AI
The cancellation matters beyond one contract. The Loughton site was one of the flagship investments announced to position the UK as an AI superpower, and its collapse for grid reasons rather than commercial ones shows where the real constraint now sits. Energy availability, connection queues and local opposition are shaping the European data centre landscape more than chip supply or customer demand.
For engineering teams, the practical lesson is that capacity planning is no longer only about choosing a region on a cloud console. Multi-year commitments to a single facility or provider carry real risk when power and construction timelines can slip by years. Distributed architectures across several European regions, sovereign cloud options and a clear exit strategy for capacity contracts are now baseline hygiene for any AI or data platform roadmap.
