A major datacentre project in Loughton, Essex, announced in 2025 as the UK’s largest AI supercomputer, will not meet its intended launch deadline next year and may not become operational until the early to mid-2030s. The delay stems from power supply constraints at the local grid level, according to reports from industry sources.
UK Power Networks, the distributor responsible for connecting the site to the grid, has informed Nscale, the startup developing the project, that sufficient electricity capacity will not be available during the originally scheduled timeframe. This represents a significant setback for the scheme, which was referenced by the government when unveiling its AI strategy in 2025. The datacentre is expected to require up to 90 megawatts of capacity, equivalent to the energy needs of approximately 315,000 homes.
Nscale stated its continued commitment to the project and indicated it is exploring alternative solutions, including onsite power generation and measures to accelerate the grid connection process. The company has also completed clearing of the Loughton location, which had previously been identified as an operational scaffolding yard.
The delays reflect broader challenges within the UK’s energy infrastructure. Ofgem, the energy regulator, has identified a significant backlog of datacentre connection applications, with 315 facilities currently awaiting grid connections representing 73 gigawatts of demand, substantially exceeding the nation’s peak energy consumption of 45 gigawatts. Experts attribute infrastructure work requirements at the National Grid transmission level as a primary bottleneck affecting many large-scale datacentre projects.
The government has acknowledged the situation and stated that reforms to the connection application process are underway, with the National Energy System Operator and Ofgem working to prioritize projects and support economic growth. Officials described current efforts as reversing underinvestment in grid infrastructure through what they characterized as the largest upgrade to the system in recent decades.
