UK grid bottleneck threatens AI ambitions

the uk's energy regulator ofgem is facing a challenge in balancing the need to deter speculative data center projects from clogging the power grid with the risk of driving legitimate projects away. the queue to join the uk grid has ballooned, with 73 gigawatts of new data center demand added between november 2024 and june 2025. ofgem's proposed reforms include a steep, nonrefundable deposit that could reach hundreds of millions of dollars for large data centers and requirements for developers to line up customers and prove funding. the goal is to enable viable data centers to connect more quickly, supporting the uk's ai ambitions and future economic growth.
