New York has become the first state in the United States to impose a moratorium on new datacentre construction, halting approvals for any facility requiring more than 50 megawatts of power. The move, announced this week, puts the brakes on the Empire State's booming 'bit barn' sector while regulators draft fresh rules to balance economic growth with environmental protection and consumer electricity costs.
The pause affects all new build applications for large-scale datacentres — the kind that power cloud computing and artificial intelligence workloads — and is expected to last until the New York State Public Service Commission finalises a framework for siting, energy efficiency, and cost allocation. The decision reflects growing unease among US policymakers about the strain that hyperscale datacentres place on local grids and the risk that their power demands could push up household bills.
For UK businesses and technology leaders, the New York moratorium is a bellwether. Britain's own datacentre industry has expanded rapidly, particularly in the 'Datacentre Alley' corridor west of London, but has come under scrutiny from the Information Commissioner's Office and environmental campaigners. The UK's National Grid has warned that datacentres could consume up to six percent of the country's electricity by 2030, up from roughly one percent today, raising questions about grid stability and the nation's net-zero commitments.
Under the EU AI Act, which also influences UK regulatory thinking, large-scale compute infrastructure is subject to transparency and energy-efficiency reporting requirements. While the UK is no longer bound by EU law, the ICO has indicated it expects datacentre operators to demonstrate compliance with carbon-reduction targets and to mitigate the environmental impact of training and running large AI models. Industry experts caution that without a clear domestic framework, the UK risks both a planning bottleneck and a backlash from communities concerned about noise, water use, and visual intrusion.
Dr Eleanor Cross, a digital infrastructure analyst at the Centre for Policy Studies, said: 'New York's move is a shot across the bows for the entire sector. UK operators should not assume that planning permissions will keep flowing freely. The government needs to set out a national datacentre strategy that reconciles digital growth with energy affordability and climate goals.'
For now, UK datacentre developers are watching closely. The British Infrastructure Group has called for a 'smart growth' approach that encourages locating new facilities near renewable energy sources and using waste heat for district heating. Failure to act, experts warn, could see the UK follow New York's lead — or worse, lose investment to countries with clearer, more permissive rules.
