Ofgem proposes upfront fees for data centre grid links

Britain's energy regulator has proposed imposing substantial upfront fees on large data centre developers to secure grid connections, aiming to clear a massive backlog of speculative projects that threatens to delay the country's energy transition and economic growth. The consultation, launched by Ofgem on July 29, 2026, would require developers to lodge refundable financial commitments when accepting a connection offer, with the funds forfeited if projects are abandoned.

The move follows an unprecedented surge in applications for electricity connections, which more than tripled from 41 gigawatts (GW) in November 2024 to 125 GW by June 2025. Data centres account for at least 73 GW of this requested capacity across 315 projects, a figure that far exceeds Britain's peak electricity demand of approximately 45 GW. Officials are concerned that speculative schemes, which may never be built, are reserving scarce network capacity and blocking viable developments from connecting.

Under the proposals, large data centre projects seeking connections of at least 40 megawatts would pay a fee ranging from £237,500 to £712,500 for every megawatt of capacity requested. This sum represents...
