The UK's largest AI supercomputer may not be operational until the 2030s due to insufficient power supply, according to a start-up. The data centre could eventually expand to consume up to 90 megawatts of power. This level of energy use, if maintained continuously, would be equivalent to the annual electricity consumption of about 315,000 typical UK homes, based on 2026 figures from the UK energy regulator Ofgem.
The start-up has outlined plans for the data centre to grow from its current 50 megawatts capacity. However, the expansion is constrained by the availability of reliable and sustainable energy sources. Ofgem's data highlights the increasing demand for electricity in the UK, particularly in sectors like technology and artificial intelligence.
The delay underscores the challenges of scaling up large-scale computing projects in a country already facing energy constraints. The start-up is now exploring alternative energy solutions and partnerships to ensure long-term power supply. The project remains a key part of the UK's strategy to advance AI research and innovation.
