Stalled Mega-Datacentre Projects Threaten AI Growth

The 2,000-acre Prince William Digital Gateway in Prince William County, Virginia, was blocked by a local court and lost a key investor after legal challenges highlighted its proximity to a Civil War battlefield. The halt adds the site to roughly 125 announced datacentre projects that the Uptime Institute expects will be delayed or cancelled.

Developers announced 250 projects over 100 MW between 2021-2024, enough to power about 300,000 homes. Six mega-gigawatt proposals—five in the United States and one in the United Arab Emirates—target at least 5 GW each, comparable to Ireland’s peak demand. If all run at 25 % capacity, they would consume 1.3 % of projected global electricity in 2025, nearly doubling current datacentre demand, with about 80 % of new power needs coming from U.S. sites. The seven largest planned datacentres together propose 45 GW of onsite power, matching the United Kingdom’s peak demand.

Uptime’s January report warned that surging datacentre power demand cannot be met by grids already under strain, especially in North America. Google admitted its cloud business is “compute-constrained,” reflecting limited capacity for AI services. Andrew Batson of JLL said industry innovations such as battery storage and onsite generation will address energy constraints and keep construction on schedule.

A legal brief argued the development would “mar the solemn nature” of the historic battlefield. Community and environmental groups have repeatedly opposed large-scale datacentre proposals, citing visual impact, water use and the broader environmental footprint of massive electricity consumption.

Uptime’s outlook is pessimistic about near-term grid capacity, while JLL’s research suggests lease signings and groundbreakings in early 2026 are slightly ahead of schedule. Public data on specific grid upgrades for the identified projects remain unavailable, leaving the feasibility of meeting the projected 45 GW of onsite power uncertain.

• “If the development is allowed to proceed, the solemn nature of this historic site would become marred by sitting in the shadow of the monstrous datacentres, along with their associated electrical infrastructure,” — Legal brief, Prince William case

The Guardian

• “The global supply chain just cannot support the level of projects out there, on the timeline that is projected. The scale is such that it’s going to slow things down,” — Jay Dietrich, Research Director, Uptime Institute

• “Surging datacentre power demands, particularly in N[orth] America, cannot be supported by power grids already operating under heavy strain,” — Uptime Institute, January report

The Guardian

• “I am confident that the industry will work through the energy challenges,” — Andrew Batson, Global Head of Datacentre Research, JLL

Groundbreaking ceremonies for several U.S. projects are slated for early 2026, while Virginia regulators review permitting rules that balance heritage preservation with infrastructure needs. Stakeholders expect further legal challenges and grid-capacity studies that will shape the pace of AI-driven datacentre expansion.
