Capital is no longer the bottleneck for data centres; consent is. April 2026 brought the first US statewide moratorium, the IEA's hardest figures yet on growth and onsite gas, and a UK grid queue that exceeds Britain's peak demand. Operators with consent push concrete; operators without it pause, relocate, or burn gas behind the meter.
Consent has replaced capital as the gating constraint; operators with cleared sites attract all the capital, operators without them burn gas.
The IEA's 16 April release put global data centre electricity demand growth at 17% in 2025, six times the overall electricity growth rate, with five hyperscalers' capex topping $400 billion and projected to reach roughly $700 billion in 2026.
The IEA (International Energy Agency) reported on 16 April 2026 that global data centre electricity use grew 17% in 2025, six times the overall grid growth rate. AI-focused facilities were up around 50%. Five major tech companies collectively spent over $400 billion on capital investment last year.
The IEA projects capex rising a further 75% in 2026 to roughly $700 billion. Nuclear power agreements for data centre supply jumped from 25 GW to 45 GW in 16 months.
OpenAI paused its planned UK Stargate data centre at Cobalt Park, North Tyneside, on 23 April 2026, citing an 'unfavourable regulatory environment' and elevated energy costs.
OpenAI paused its planned data centre at Cobalt Park, North Tyneside on 23 April 2026, citing an 'unfavourable regulatory environment' and high energy costs. The Blackstone and Nscale components of the wider UK AI Growth Zone programme continue.
The pause is the first documented case of a Stargate partner withdrawing from a non-US site on regulatory grounds. It lands in a week when the UK grid-connection queue hit 50 GW against a 45 GW national peak.
The UK grid-connection register holds 50 GW of data centre demand from roughly 140 sites, against a national peak electricity use of 45 GW recorded on 11 February 2026.
United KingdomBritain's grid-connection register held 50 GW of data centre demand from around 140 facilities by February 2026. The national peak on 11 February 2026 was 45 GW. The total UK demand queue hit 125 GW by mid-2025, up from 41 GW in November 2024.
The data centre sub-queue alone now exceeds national peak demand. Ofgem launched three reform workstreams, but none shorten the physical build time for new transmission infrastructure.
Maine's legislature passed the first US statewide moratorium on large data centre development on 22 April 2026, with twelve further states carrying active bills and a Sanders/AOC federal proposal now in play.
United KingdomMaine's legislature passed the first US statewide data centre moratorium on 22 April 2026, pending Governor Janet Mills's signature. Good Jobs First counts 12 states with active moratorium bills in the 2026 session, including proposals in Oklahoma and Vermont.
Senators Bernie Sanders and Alexandria Ocasio-Cortez have introduced a federal version covering environmental, energy, labour, and civil-liberties conditions. Twelve state bills in one session moves moratorium legislation from a local fringe position to a coordinated national posture.
xAI received approval in March 2026 for 41 natural gas turbines totalling 1.2 GW to power its Colossus complex; Meta's El Paso project will run on a 366 MW behind-the-meter gas array.
xAI received approval in March 2026 for 41 natural gas turbines totalling 1.2 GW at its Colossus complex in Memphis. Meta's El Paso data centre runs on a 366 MW behind-the-meter gas array. Kevin O'Leary's Wonder Valley campus in Alberta includes a 7.5 GW bring-your-own-power gas plan.
All three bypass grid connection queues by generating power on site. Three such commitments in a single quarter marks behind-the-meter gas as the default model for large AI facilities.
GE Vernova's gas-turbine backlog reached 80 GW in December 2025, with deliveries booked into 2029 and reservations on track to sell out through 2030 by year-end.
GE Vernova's gas turbine backlog reached 80 GW in December 2025, with deliveries booked into 2029. The International Energy Agency projected 15 to 27 GW of onsite natural gas will power US data centres by 2030.
Operators who missed the reservation window in 2024 now face a multi-year wait for turbines. The behind-the-meter gas escape route has its own queue.
Ecologistas en Acción filed Spain's first data centre legal challenge at the Tribunal Superior de Justicia de Aragón in January 2026, contesting the regional government's agreement with Amazon for 30 buildings and 10 substations.
Ecologistas en Acción filed Spain's first data centre lawsuit in January 2026. It targets Amazon's agreement to build 30 data centres and 10 substations in Aragón. Aragón has overtaken Lisbon as Spain's largest data centre hub.
The challenge focuses on water use and infrastructure development. Amazon's build runs under a Programme of General Interest spanning land acquisition in 2026 and construction through 2036.
On 12 February 2026, the Loudoun County Planning Commission voted 7-1-1 to recommend a 268,700 sq ft data centre rezoning, in a state losing more than $1 billion a year to data centre tax abatements.
Good Jobs First found Georgia, Virginia, and Texas each forgo over $1 billion annually in data centre tax abatements. Ten further states lose over $100 million a year each. Loudoun County, Virginia voted 7-1-1 on 12 February 2026 to recommend a 268,700 sq ft rezoning.
Loudoun rejected its own moratorium in March 2025 and keeps approving projects. Its Phase 2 standards are not due for adoption until December 2026.
Pure DC's 110 MW Dublin microgrid became operational in April 2026, explicitly designed to bypass the Irish grid-connection queue and the CRU's 80%-renewables-within-six-years rule.
Pure DC's 110 MW microgrid went live in Dublin in April 2026. It bypasses the Irish grid queue and avoids the CRU (Commission for Regulation of Utilities) 80%-renewables rule for new data centres.
The CRU had required EirGrid and the distribution network operator to publish a data centre connection process by 31 March 2026. No publication appeared in the 26 days after that deadline.
Microsoft's Mount Pleasant phase 1 draws 8 million gallons of water a year, a figure released only after Milwaukee Riverkeeper sued the city of Racine to break a non-disclosure clause in the development agreement.
Microsoft announced a basin-level water disclosure framework in January 2026, committing to replenish more water than it withdraws. Its Racine, Wisconsin agreement contained a non-disclosure clause on community-impact data that Milwaukee Riverkeeper had to sue to break.
The released figure was 8 million gallons per year for phase one of a $3.3 billion site. Amazon still publishes no electricity figures at all.
Blackstone committed £10 billion to a Blyth data centre via QTS in April 2026, Amazon announced €33.7 billion of EU cloud and AI investment, and Stargate UAE phase 1 poured over 100,000 cubic metres of concrete.
United Arab EmiratesBlackstone committed £10 billion to a Blyth data centre, its largest UK infrastructure bet. Amazon pledged €33.7 billion of European AI investment in April 2026. In Abu Dhabi, Stargate's first phase has poured over 100,000 cubic metres of concrete with 5,000 workers on site.
The Abu Dhabi site targets 200 MW by Q3 2026 and 1 GW within three years. It runs on Gulf kafala labour contracts, the fastest large-scale AI build outside the United States.
Stargate US launched at $500 billion in January 2025, but only Abilene is partially operational at roughly 1.2 GW against a nominal 10 GW programme; Latitude Media forecasts 30-50% of 2026 data centre completions will slip.
United StatesStargate US launched in January 2025 at a $500 billion headline, with $100 billion committed at launch. By April 2026, only Abilene, Texas is partially operational at 1.2 GW of a nominal 10 GW programme. SemiAnalysis questioned whether SoftBank can finance the full sum.
Latitude Media estimates 30-50% of 2026 data centre completions will slip. Only 5 GW of 16 GW globally planned for 2026 is under construction.
The constraint side is strengthening. Maine's passage establishes a legislative template twelve other states can copy; the Sanders-AOC federal bill puts moratorium advocacy in both chambers of Congress for the first time. Ofgem's queue reform can accelerate queue discipline but cannot shorten physical transmission build timescales. The IEA's own central scenario projects 15-27 GW of US onsite gas by 2030, conditional on grid bottlenecks persisting at roughly current severity. The capital side is adapting rather than retreating. The likely escalation path runs through three named decision points: Governor Mills's Maine signature before May 2026, Ofgem's AI-demand consultation response this quarter, or a TSJ Aragón precautionary injunction on Amazon's Aragón land acquisition before mid-2026.
