Microsoft has withdrawn from an agreement to become the principal customer of a major artificial intelligence data centre being developed by Nvidia-backed Nscale in the United Kingdom, following prolonged delays in securing electricity supply.
The decision represents a setback for Britain’s ambition to become a leading global destination for artificial intelligence infrastructure and investment.
The proposed facility, located in Loughton, Essex, was expected to provide substantial computing capacity for Microsoft’s Azure cloud services.
However, electricity network officials reportedly informed Nscale that the site might not receive the necessary grid connection until the 2030s, several years later than originally planned.
Microsoft confirmed the withdrawal on Monday, October 19, but emphasised that the decision concerned only the affected development.
The technology company maintained that it remained committed to its wider partnership with Nscale, including other projects intended to expand artificial intelligence infrastructure internationally.
Nscale also acknowledged the setback, explaining that electricity connection difficulties affecting the London area had disrupted the project’s timetable.
The company insisted that its commercial relationship with Microsoft remained intact and that the development would continue to be pursued.
It disclosed that alternative electricity sources were being considered for the Loughton facility, alongside opportunities to develop additional data centres elsewhere in Britain.
The project was among several technology investments announced during United States President Donald Trump’s visit to Britain in September 2025.
Under the original arrangement, the facility was expected to begin operations in early 2027, delivering approximately 50 megawatts of computing capacity.
Plans included the deployment of 23,040 Nvidia GB300 graphics processing units to support advanced artificial intelligence applications and Microsoft’s cloud computing services.
However, delays in electricity infrastructure have emerged as a major obstacle to the rapid construction of energy-intensive data centres.
Industry reports indicate that some projects in Britain face grid connection delays extending several years, complicating investment decisions and infrastructure expansion.
The development comes as Nscale prepares for a proposed initial public offering in the United States, with Microsoft and artificial intelligence company Anthropic expected to remain among its major customers.
Nscale has expanded rapidly since its establishment, reporting more than $103 billion in total contracted value.
The company’s continued expansion reflects growing demand for specialised computing infrastructure as businesses invest in developing and operating increasingly sophisticated artificial intelligence systems.
Nevertheless, Microsoft’s withdrawal highlights the challenges facing governments and technology companies seeking to expand AI computing capacity without corresponding improvements in electricity generation and transmission.
While the broader Microsoft-Nscale partnership remains in place, the future timetable for the Loughton facility will depend on whether the developer can secure a viable alternative power supply.
