As data center Developers compete to get a share of the billions of dollar flowing into the artificial intelligence The queue for joining the UK power grid is now jammed up with projects which will never be built. This snarl increases the already long wait for feasible projects and complicates grid expansion plans and energy forecasting.
Ofgem (the UK energy regulator) announced in July that it would be implementing a new regulatory framework for the UK. laid out a proposal Force phantom is the opposite of what it means to say. data centers The queue is swollen. Developers would have to pay a large, non-refundable deposit, which could reach hundreds of millions for very large data centers, as part of the finalized plans that will be announced after the industry’s feedback process ends in September. In addition, developers will be required to confirm customers ahead of time and provide proof that they are able to fund their projects.
Ofgem is faced with a Goldilocks dilemma: the reforms need to be heavy enough to discourage speculators, but not too burdensome that it drives legitimate data centers to foreign shores and undermines UK ambitions to reach international standards. the voracious demand For the computation required to run complex AI models.
Similar grid congestion problems are affecting data centers developers almost everywhere afflict the US There are many countries in the world. across Europe. However, the US has a different approach. highly desirable market, Ofgem’s reforms risk making the UK—already unattractive for the high cost of energy and dearth of land—one of the world’s most expensive places to build a data center, industry experts believe.
Buildout of data centers is on the rise “is bringing a huge amount of capital investment into the UK,” Alex Burgoyne is the head of datacenters at Knight Frank, a real estate consulting firm. “We don’t want to shoot the golden goose.”
Ofgem states that they will consider industry concerns when deciding on fees, however the differences in international energy markets makes it difficult to compare like for like. “We recognize data centers are a key part of the UK’s AI ambitions and future economic growth. Enabling viable data centers to connect more quickly is an enabler of this,” Nathan Macwhinnie tells WIRED, in a written statement, that he is Ofgem’s deputy director, strategic planning, and connections.
Queue to join UK grid began to balloon Around 2024 the Government will begin to implement the new laws designated data centers “critical national infrastructure.” The total demand for energy of all the projects on the queue has increased between November 2024 to June 2025 from 41 gigawatts up to 125 gigawatts. according to Ofgem. New data centers make up 73 gigawatts of that—equivalent to one and a half times the peak demand for the entire UK last year—and counting.
The Government has said It believes that much of this demand is an illusion. “It’s absolutely insane,” says Taco Engelaar, managing director at grid optimization company Neara. “No one really understands … what the real grid demand will be because of these phantom projects.”
A lack of incentives is the main cause for the long queue. Developers are faced with a long wait to gain grid access and the cost to apply was only a few thousands dollars. They may as well join, even though they don’t have a plan for development. The bet is risk-free and allows developers to secure a future where demand for computation will continue to rise.
Grid operators must consider the impact of all large infrastructure projects on their network before they can grant individual connections. This means that phantom centers may prolong delays in viable projects. “They have to treat every project as serious when they try to study whether the system can handle them,” Olivier Darmouni is an associate professor at HEC Business School and a published author. research The impact of AI technology on electricity grids. “The more speculative projects are especially damaging because they make these studies more complex, more expensive, longer.”
