One has already been announced in Northumberland, but a decision on a second, planned for Teesside in north-east England, has been delayed until the end of this year by Miliband, whose department has to make a call on whether to greenlight plans for a hydrogen plant on the same site, which could preclude data centers being built there. “There is a large fight going on inside of government where Ed Miliband seems to have set himself up against not just the prime minister, but a number of secretaries of state,” Houchen told POLITICO during Conservative Party Conference in October. The nuclear option Long term, the government is betting on a cleaner, but more expensive energy source — nuclear, specifically small modular reactors. Michael Jenner, CEO of nuclear firm Last Energy UK, said they had received dozens of enquiries from data center builders and argued that the green credentials of nuclear was an ace card it could play against rival bids from gas companies. “If you're thinking about building data centers in South Wales, which a lot of people are, you have a problem with the authorities because they don't want new gas there,” he said. In September, EDF Energy announced plans to work with American company Holtec International building a crop of data centers next to small modular nuclear reactors at a disused coal plant in Nottinghamshire. The Tony Blair Institute, which is influential with government ministers, has argued nuclear has a “unique” advantage when it comes to data centers. It also believes the country should scale back its net zero plans in favor of reducing energy costs to attract data center investment. “Cheap, firm power is ... not a 'nice to have' but a prerequisite for attracting AI-driven growth,” it argued in a report last month. Gas, meanwhile, should be part of that energy mix, the Institute recommended in July. Firms represented at the AI Energy Council have urged ministers to green-light greater use of gas turbines in the short term. The clock is ticking. Gas, nuclear, renewables or even wooden pellets — ministers willing on an AI revolution need to make decisions fast.
