US Utilities Weed Out 'Phantom' AI Data Centers Over Grid Strain

The billion-dollar queue of ghost projects

Developers have asked US utilities for 1,066 gigawatts of power connections, an amount equivalent to roughly 83% of the nation's total utility-scale capacity at the end of 2025.

On paper, the artificial intelligence boom looks set to consume nearly every watt the United States can produce. In reality, power companies have realized that much of the line waiting for hookups consists of phantom projects that exist only on paper.

Analysis by Wood Mackenzie indicates that electric utilities will likely commit to serving only about 28% of the massive 1,066GW backlog. Roughly 12% already holds firm service commitments, with another 17% deemed plausible. The rest is mostly noise: developers submit the identical 1,000MW proposal to three or four different utility regions simultaneously, waiting to see who promises power first before abandoning the others.

Land speculators and private equity shops have also flooded queues, betting that securing a prospective power reservation will make empty farmland dramatically more valuable to flip, even without architectural plans or an actual anchor tenant.

Exelon tests the bluff with cash collateral

To separate real builders from speculative flippers, utilities are now insisting on transmission security agreements. These contracts require developers to post credit obligations, pay hefty study fees, and agree to shortfall penalties if their promised power consumption never materializes.

The impact of charging real money was instant. Mid-Atlantic and Midwest operator Exelon saw its high-probability data center load plunge almost 40%, falling from 18GW down to 11GW after instituting the requirement. Its broader pipeline of projects under evaluation contracted from 43GW to 25GW.

Similar infrastructure logjams are already shaking international markets, as seen when Microsoft abandoned a major UK data center buildout due to projected grid connection waits stretching toward 2030.

Residential rate hikes force regulatory action

Power companies cannot simply ignore speculative filings because grid expansion costs are pooled. If a regional transmission organization authorizes billions of dollars in new substations and high-voltage corridors for prospective AI clusters that never break ground, ordinary ratepayers get stuck footing the bill.

That risk is no longer theoretical. Regional transmission operator PJM saw its summer capacity auction clear at the maximum price cap for the third consecutive cycle while still missing its target margin by 6.8GW. PJM's market monitor subsequently reported that 4,017MW of projected data center demand—amounting to 42% of assumed growth—had quietly been canceled or delayed.

To protect their balance sheets, utilities have stretched required commitment terms. Data gathered by Halcyon shows average minimum contract durations for massive industrial power users jumped to 10.8 years, more than double the 4.6-year average standard before 2024.

What it means for US consumers and businesses

For American households, the fight over speculative data center queues directly affects monthly bills. In Virginia, Henrico County recently directed schools and municipal offices to trim electricity use following a 24.9% rate increase driven by local transmission buildouts.

Regulators in several states, including Virginia and Texas, are drafting rules to ring-fence data center substation costs and prevent utilities from passing commercial interconnection expenses onto residential accounts.

The gold rush mentality surrounding artificial intelligence infrastructure is hitting the hard limits of physical electrical engineering. Until tech giants prove their power needs with binding capital commitments, utilities will treat prospective gigawatts as ghosts.
