Britain has applied for 3× more data centre electricity than it will ever need.

⚠️

Planning authorities are processing applications worth tens of billions of pounds — without checking whether the demand exists. Here is what the official data shows.

50 gigawatts queued to the British grid

That is three times the country's entire peak electricity demand. Applied for. In the queue. Right now.

What is queued vs what is needed

50 GW Applied for
right now

14.6 GW What Britain
needs by 2050

The numbers in plain English

50 GW Data centre applications in the British grid queue today

14.6 GW Maximum Britain will need by 2050, according to the grid operator

2.4 GW Actually connected and running today

21× The queue compared to what is actually built — the clearest measure of speculative excess

12 wks The window most communities have to object to a planning application — if they know about it at all

What this means for communities

Planning applications for facilities that may never be built are being processed right now — on land that cannot be returned.

Ancient landscapes. Green belt land. Protected hillsides. All being considered for infrastructure that independent bodies say will never be needed. Communities have 12 weeks to respond. Most never know the clock is running.

This has happened before

History calls it a speculative bubble. Britain's Railway Mania. The fibre-optic glut. The pattern is the same.

A real technology. Far more investment than the technology needs. Promoters profit. Late investors and local communities carry the consequences.

"Communities deserve better than a 12-week window on decisions that will affect their land, their water and their grid for decades."

What we are calling for

→An immediate moratorium on greenfield data centre applications until planning rules catch up with the pace of development.

→Applicants must demonstrate secured end-customer demand before any greenfield application is processed.

→Full water consumption estimates must be published alongside every planning submission.

→A brownfield-first policy for data centres — consistent with other major infrastructure categories.
