Cancelled data center projects leave utilities with stranded infrastructure costs passed to ratepayers; capacity reassignment takes months.

When a large data center project pauses or cancels, it leaves behind far more than an empty site. Connecting a facility to the power grid typically requires securing a place in a utility's interconnection queue, posting a deposit to hold that place, and often requiring the utility to build or expand substations or transmission lines tailored to the project's specific capacity needs. Once a project stalls, these commitments don't simply disappear—they're reassigned, clawed back, or stuck in limbo. The resulting costs surface in places few people examine closely.

Nearly one in five data center interconnection requests never materialize into actual load, according to the Capgemini Research Institute's 2026 report, "AI Meets the Grid: Shaping the Data Center Power Play." The report, based on a January 2026 survey of more than 600 electricity executives, found that 67% characterized these as "phantom" load requests, with roughly 19% never materializing. The gap reveals a structural problem: utilities are being asked to plan and invest ahead of uncertain, fluid demand.

**Stranded Capacity: Who Pays, and When?**

It's tempting to assume developers absorb the losses and everyone else moves forward. The reality is more complex.

Developers do lose real money on sunk costs—primarily engineering, permitting, and early construction that cannot be recovered, according to Sam Tabar, CEO of WhiteFiber. But utilities are equally exposed. By the time a project falters, they may have already begun building substations and transmission lines intended to serve it. Those investments typically remain as part of their rate base, whether the anticipated load materializes or not. Tabar calls this outcome the least examined aspect of the problem. "It is this cost socialization that is largely unaccounted for in the public discussion around data center projects," he said.

Timing determines who ultimately bears the cost, according to Ildi Telegrafi, a Policy Fellow at the Alliance for Innovation and Infrastructure. If a project is canceled before any utility construction begins and before customers are paying for it, the developer retains the cost. If construction is underway or finished when the expected load disappears, the bill shifts to other customers.

Jim Tyler, CEO of Erthos, frames this outcome as a genuine regulatory puzzle with no default answer—only options negotiated case by case. "This creates highly complex regulatory dilemmas about whether these costs should be reassigned to other projects, sit with the utility, or enter a rate case to be paid by ordinary customers," he said.

**The Interconnection Queue Reality**

There's a common assumption that when one project cancels, the next one in line simply advances. It rarely works that way.

"Interconnection studies are done by location and for a specific load," Tabar said. Substituting a different project at the same point typically triggers a fresh study because the original assumptions—load size, delivery point, and timeline—may no longer apply. That restudy is not a formality. "Restudies take time, sometimes six months to over a year, and the project inherits updated assumptions about grid conditions that can change its economics significantly," said Whitaker Irvin Jr., founder and CEO of Q Hydrogen.

**How Cancellations Cascade: Three Case Studies**

Three recent cases illustrate how differently a cancellation or reassignment can unfold. Importantly, replacing a project at the same site often requires new environmental reviews, fresh permits, and updated community engagement, each of which can introduce different timelines and levels of local support. These factors compound the timing and cost considerations that ripple through utilities and markets.

*Georgia.* Atlanta-based T5 Data Centers proposed a project near Fort Gordon in Augusta in 2022, then withdrew before year's end. Eagle South LLC later filed plans for "Project Eisenhower," a $2 billion, 2.1 million-square-foot data center campus on the same site, attracted by the same nearby Georgia Power substation that had made the location valuable to T5. The project is in site development but delayed relative to its original schedule for completion in the second quarter of 2026.

*Virginia.* QTS and Compass Datacenters both withdrew from Prince William County's "Digital Gateway" corridor, a 2,139-acre plan that could have drawn up to $30 billion in investment, after courts invalidated the county's rezoning approvals. Compass withdrew in April 2026 after spending $40 million. QTS ended its remaining appeals in July. The corridor sat atop Dominion Energy's transmission infrastructure, which the county had spent years marketing as the project's core selling point.

*Cloud leases.* Not every reassignment involves a utility filing. Microsoft walked away from roughly 2 GW of data center leases and projects across the US and Europe in early 2025. Some capacity in Europe was reportedly reassigned to Google and Meta.

**What the Ripple Effect Misses**

These cases point to divergent outcomes for a shared problem. In Georgia, a successor data center project directly reused the site and power access left behind by a canceled one, though years separated the two. In Virginia, hard-won capacity and transmission access remain without a confirmed successor. In the cloud-lease scenario, a competitor simply stepped into the space a rival had abandoned—no site or substation involved.

"The biggest shock has been the duration of the ripple effect," Tabar said.

Most people assume that when a project is canceled, the capacity it would have consumed simply frees up and the market adjusts. Tabar sees it differently: splashy announcements of proposed developments receive outsized attention, while cancellations and the committed infrastructure costs left in limbo receive far less scrutiny. The result is a persistent structural underestimation of what data center volatility actually costs the grid and ratepayers.
