35-50% of planned AI data centres are behind schedule
A new white paper from the Oxford Smith School and Marex points to a significant “delivery gap” for planned AI data centres, with up to 50% running behind schedule.
“This gap will have significant consequences for energy markets, climate progress, and AI development,” says lead author Dr Antif Ansar, Programme Director of the Oxford Programme on the Sustainable Future of Capital Intensive Industries.
A key finding of the paper is that markets appear to be pricing in the announcement curve, not the delivery curve. Commodity and equipment markets (copper, transformers, electrical steel) are responding to lofty buildout claims that may materialise years late or not at all, risking short‑term overpricing followed by oversupply.
“Media and markets are expecting a rapid, exponential ramp-up of Al infrastructure. The evidence tells a different story: a rollout that is delayed, lumpy, and constrained by physical realities,” says co-author Dr Stephen Lezak. “Our analysis suggests a significant share of announced capacity is inflated or postponed - ‘bragawatts’, not real assets."
“If enterprise AI adoption does not scale as expected, the result could be stranded assets or sharply lower utilization,” warns co-author Dr Guy Wolf, Global Head of Market Analytics at Marex.
The white paper details how execution challenges are reshaping energy markets by raising local power costs and driving increased natural gas usage. While power grids struggle to catch up, operators are increasingly turning to on-site gas turbines, fuel cells, and battery systems. By 2028, off-grid generation for data centres could account for a substantial uptick in natural gas usage not captured in official power sector statistics.
The authors conclude by warning that the economic case for the scale of buildout remains unproven: “The winners will be those who balance ambition with realism – investing in the future of AI without losing sight of the practical constraints of the present.”
