  "account": "The United Kingdom's largest planned AI supercomputer, set to launch next year, may face a delay until the 2030s, due to difficulties securing sufficient electricity. This project was announced as part of the first technology agreement between the UK and the United States, as the UK seeks to boost its artificial intelligence industry. The site, being developed in Loughton, east of London, by Nscale, a UK-based firm that includes US chipmaker Nvidia as an investor, is expected to host approximately 23,000 Nvidia AI chips by 2025. These chips will be interconnected to form what Nscale claims will be the United Kingdom's largest AI supercomputer, intended to support Microsoft's Azure cloud services.\n\nHowever, UK Power Networks (UKPN), responsible for connecting the site to the local power grid, has informed Nscale that the grid may not have enough electricity to supply the site until the early to mid-2030s. This concern stems from the need for upgrades to the broader national transmission network. National Grid, which manages England and Wales' power grid, is collaborating with NESO, the national system operator, and local network operators to expedite these connections. Nscale is also exploring on-site power generation and discussing potential ways to expedite the connection with UK Power Networks.\n\nThe data centre at Loughton could eventually expand from 50 to 90 megawatts of power, which, if used continuously, would consume as much electricity annually as roughly 315,000 typical UK homes, according to figures from UK energy regulator Ofgem. This Loughton site is part of Nscale's broader plan to install nearly 59,000 Nvidia AI chips across data centres in the UK. On a European scale, data center electricity consumption is projected to increase from 96 terawatt-hours in 2024 to 236 terawatt-hours by 2035, as highlighted by UK-based energy think tank Ember.\n\nRecent developments have seen Scotland halt new approvals for hyperscale AI data centres due to concerns over whether the country's energy grid can handle the rapidly rising demand. Similarly, Amsterdam has restricted new data centres and expansions over issues of space and power, while a proposed bill in Denmark would grant large electricity users, including data centres, lower priority in grid connections.",
