The government has launched plans to clamp down on speculative electricity grid connection applications as part of wider reforms aimed at accelerating infrastructure projects that support economic growth.
Ministers say the move is designed to prioritise strategically important developments such as AI data centres, EV charging hubs and major industrial sites, many of which have faced long delays securing power connections.
The queue for demand connections to the UK’s transmission network has surged by 460% in just six months to June 2025, according to government figures. Officials say speculative applications have inflated the pipeline, contributing to waiting times of up to 15 years for some projects.
The reforms aim to tighten the conditions for joining and remaining in the grid connection queue, ensuring only viable and committed developments are allowed to progress.
AI GROWTH ZONES
Under the proposals, the government could publish a list of strategically important projects – including those linked to new AI Growth Zones – which would receive priority access to grid capacity as it becomes available.
Energy Minister Michael Shanks (main picture, inset) says: “Industries that can bring real economic benefits are ready and waiting to be powered up, but the queue for grid connections has grown exponentially due to speculative applications.
“We will prioritise the projects, including AI datacentres and industrial sites, that are ready and needed to deliver growth and jobs for communities across Britain.”
The reforms form part of a broader programme to modernise the electricity network and support the government’s clean energy strategy, which aims to unlock billions of pounds in private investment while improving energy security and supporting new infrastructure development.
NEW HOMES RISK
Lawrence Turner, Director, Boyer, says: “The Government is right to clamp down on speculative grid connection requests if the queue has genuinely become clogged with projects that were never likely to move forward.
“Tightening the conditions for entering and remaining in the queue should help redirect grid capacity toward schemes that are genuinely deliverable. If applied robustly, that could materially shorten connection times for viable projects.”
But he adds: “There is a flip side. Housing delivery increasingly depends on access to grid capacity, and in some areas, power constraints are already slowing development.
“If strategic infrastructure begins to receive preferential access to electricity connections, there is a real possibility that new homes could find themselves competing with server farms for power.
“The question becomes is, when electricity is scarce, do we power servers first, or homes? Both are strategic development.”
