UK Risks Falling Behind France in AI Data Centre Development Due to Power Capacity Concerns

Britain faces the prospect of lagging behind France in the race to construct artificial intelligence (AI) data centres, as highlighted by a senior Nvidia executive. David Hogan, the company’s European sales chief, emphasised that dwindling nuclear power capacity in the UK poses a significant challenge for developers striving to build advanced AI infrastructure.

Electricity supply has emerged as the primary limiting factor for AI development, particularly as the technology becomes more compute-intensive. Hogan noted during the New Nuclear Summit in London that nations with substantial nuclear power fleets hold a strategic advantage in establishing sovereign computing capabilities. Currently, the UK operates nine nuclear reactors with a combined capacity of approximately six gigawatts, starkly contrasting with France’s 57 reactors, which boast a total capacity of 63 gigawatts.

Many of the UK’s nuclear facilities are set to retire within the next decade, leaving only one new plant, Hinkley Point C in Somerset, currently under construction. Hogan remarked on the crucial need for a sustainable and consistent power supply to support the growing demands of AI. He stated that countries investing in nuclear energy, such as France, are better positioned to thrive in the emerging AI landscape, which requires ample energy resources.

At an AI summit in Paris, President Emmanuel Macron unveiled €109 billion worth of data centre projects, all centred around nuclear facilities. As technology giants like Microsoft, Amazon, and Google increasingly rely on nuclear power in the United States to meet growing energy requirements for AI, the UK must consider how to reinvigorate its nuclear infrastructure to remain competitive.

In response to these challenges, Sir Keir Starmer has proposed the creation of “AI growth zones” that would expedite planning permissions and establish robust electricity connections for companies. Additionally, discussions surrounding the implementation of small modular reactors (SMRs) have gained traction within the UK government, as nuclear minister Lord Hunt highlighted the potential of advanced nuclear technology to facilitate the development of AI data centres.

While Hogan noted that power requirements for a typical data centre in Europe have surged from five megawatts to 50 megawatts within just a few years, Edward Galvin, a data centre expert, cautioned that new nuclear plants may not be operational in time to meet the immediate demands of the industry. As a result, technology companies are exploring alternatives, such as gas-cooled turbines, which offer economically viable and quick-to-build solutions for ensuring reliable power supplies.

The urgency of the situation underscores the need for the UK to strategically develop its energy infrastructure to ensure it can compete effectively in the AI domain. Without such advancements, the risk of falling behind other countries, particularly France, remains significant.
