Britain’s energy regulator, Ofgem, announced on Wednesday a consultation on a proposed commitment fee aimed at reducing speculative applications from data center projects that are congesting the electricity grid. The new Data Centre Commitment Fee would require large data center developers to pay a fee ranging from £237,500 to £712,500 per megawatt (MW) when accepting a connection offer. This fee would be refundable once the project reaches grid connection status but forfeited if the project exits the grid queue prematurely, according to Ofgem.
Key Details
The regulator's proposal comes in response to a dramatic increase in connection applications, which surged from 41 gigawatts (GW) to 125 GW between November 2024 and June 2025. Ofgem noted that data centers accounted for at least 73 GW of this pipeline across 315 projects, raising concerns that speculative schemes were blocking viable developments from securing necessary grid capacity.
The connections system must work for consumers and for the projects that are ready to invest, build and connect,
said Eleanor Warburton, Ofgem’s Director for Energy System Design and Development.
Background
The rise in applications has been largely driven by the demand for AI infrastructure, with over 60 planning applications for new data centers submitted across England and Wales in 2025, a 63% increase from the previous year. The boom has attracted developers hoping to capitalize on rising land values, leading to speculation that many sites marketed as future AI campuses lack the necessary fundamentals to become operational. Pure Data Centres chief executive Dame Dawn Childs noted that
everyone’s trying to get a piece of the pie.
The proposed fees could impact the data center sector significantly, as developers may reassess their projects in light of the new costs, potentially slowing down the rapid expansion of AI infrastructure. Investors will watch for the outcomes of Ofgem's consultation and any subsequent regulatory changes that could affect future energy projects in the UK.
