Microsoft has reportedly withdrawn from an agreement to become the anchor customer at Nscale's proposed data center in Loughton, Essex.
The project was intended to provide approximately 50 MW of computing capacity and accommodate roughly 23,000 Nvidia GB300 accelerators. Reports indicate that grid electricity might not become available until the 2030s, significantly later than the project's original deployment expectations.
Nscale confirmed that the site faces electricity-related difficulties and said it is exploring alternative power sources while maintaining its broader relationship with Microsoft. Microsoft declined Reuters' request for comment, and the company has not publicly confirmed the precise reason for its withdrawal. Reuters

Why it matters strategically
This development provides a concrete example of a dependency that is becoming increasingly important across AI infrastructure.
An AI data-center developer may possess several commercially valuable assets:
Land, financing, customer commitments, computing equipment, and technical expertise.
But none of these guarantees that the facility can operate.
Without electricity available at the required capacity and date, the remaining investments cannot generate their intended returns.
This creates a distinction between three different forms of infrastructure capacity.
Announced capacity: The amount a developer intends to build.
Financed capacity: The amount supported by committed capital.
Energized capacity: The amount that can actually operate with sufficient electricity, cooling, and network connectivity.
The third is the economically decisive variable.
