Ofgem targets speculative data centre grid connections

Ofgem opened a formal consultation on 29 July 2026 targeting speculative data centre projects it says are blocking grid connection capacity in Great Britain. The regulator's press release states the reforms are designed to manage fast growth in data centre demand and support a more efficient network, language that points directly at hyperscaler and colocation pipeline volumes inflating the connection queue.

The intervention follows the broader GB queue reform programme that has already restructured generation-side connections. Extending similar discipline to large demand users marks a shift: historically, load connections have faced lighter scrutiny than generation. Ofgem is now signalling that holding grid capacity without credible delivery timelines carries the same systemic cost on the demand side.

No binding rules are in place yet. The consultation period will collect industry responses before Ofgem sets final requirements. Traders and asset managers with assets or offtake exposure near congested connection points should track whether the reforms alter expected load growth assumptions in affected areas, and whether grid operators revise local demand forecasts as speculative requests are filtered out.
