UK proposes data center connection fees to curb speculation

Jul 28, 2026

UK energy regulator Ofgem proposes new rules to curb speculative data center projects clogging the electricity grid. Developers would pay a refundable deposit of up to £712,500 per megawatt to connect. The move follows a surge in grid connection requests from 41 GW to 125 GW in one year, driven by AI, far exceeding the UK's peak demand. The plan aims to ensure viable projects can connect without delay.

Grid connection fee proposal

▪UK energy regulator Ofgem has proposed new rules requiring upfront financial commitments for projects seeking to connect to the electricity grid.
▪A data center seeking 1 gigawatt of power would face an upfront payment of hundreds of millions of pounds, which is refunded upon project completion.
▪The proposed refundable deposit is between £237,500 and £712,500 per megawatt of power requested.
▪A public consultation on Ofgem's proposals is open until September 16.

Data centre demand surge

▪The 125 GW of requested capacity is more than double Britain's peak electricity demand of approximately 46 GW in 2025.
▪The volume of electricity capacity requested for grid connections in Britain has surged from 41 GW to 125 GW in the last year.
▪The increased demand for grid connections is driven by the computing power required to train and operate AI systems.

AI infrastructure concerns

▪The UK currently has 564 listed data centres, with 24 more in planning in Scotland due to its renewable energy supply.
▪Data centres have become controversial with local residents over concerns about noise, electricity demand, and water usage for cooling.

Speculative project crackdown

▪Energy Minister Michael Shanks said the actions would help "viable connection-ready projects" proceed without being held up by speculative applications.
▪The proposal aims to prevent "speculative projects" from securing grid capacity without a firm intention to connect.
▪In addition to fees, projects would need to meet key milestones to keep their place in the grid connection queue.
