The Phantom Power Demand Problem: Why Most Data Center Power Requests Will Never Get Built

Utilities across the country are sitting on more than 1,000 gigawatts of data center interconnection requests, roughly 83% of all existing U.S. utility-scale generation capacity. According to new Wood Mackenzie analysis reported by Bloomberg, utilities will realistically commit to only about 28% of that figure. Rapidan Energy Group puts the number even lower: 20 to 30%.
In other words, most of the power data center developers say they need does not exist, and never will. There is a data center power demand problem.
This is not a minor forecasting error. It is reshaping how utilities plan the grid, how regulators respond, and how developers have to approach site selection. At LandGate, we just published a white paper on exactly this problem, the data center power crisis and the rise of behind-the-meter solutions, and this week's headlines confirm just how urgent it has become.
Where the "phantom" data center power demand comes from
The gap between requested and deliverable power comes down to one practice: developers filing duplicate interconnection requests at multiple utilities and multiple sites for the same project, then keeping every option open until one pencils out. Grid operators have no reliable way to tell which applications represent a real, fully financed project and which are speculative placeholders.
Texas illustrates the scale of the problem. ERCOT is tracking 474 gigawatts of connection requests, more than five times the grid's record peak demand. That mismatch was significant enough that Texas Governor Greg Abbott ordered an audit of data center projects on August 3, citing roughly $13 billion in industry revenue at risk. Exelon, meanwhile, has already cut its own data center pipeline by nearly 40%, down to an 11 gigawatt queue it considers credible.
Rapidan's Glenn Schwartz summed up the core issue plainly: "Grid operators don't know which ones are real." Analysts don't expect that visibility problem to resolve before 2028.
Why this matters for developers, not just utilities
Phantom demand does not just distort national forecasts. It has direct, dollar-figure consequences for anyone trying to actually build.
Interconnection lead times in PJM, which serves 67 million Americans, now regularly exceed six years for high-voltage substation connections. To even hold a place in line, developers are paying non-refundable "readiness deposits" of roughly $4,000 per megawatt, which adds up to about $1 million just to reserve a queue slot for a 250 megawatt campus. And downtime once a facility is online costs an estimated $10,000 per minute, so getting the power question wrong is not a rounding error.
There's also a labor ceiling few developers are pricing in: only about 30% of the mechanical, electrical, and plumbing workforce needed for these builds is located where 70% of projects are sited, and the U.S. adds roughly 60,000 MEP craft workers a year. That constraint alone will limit how much of the "requested" capacity ever breaks ground, regardless of how the power question shakes out.
The workaround: behind-the-meter power
Faced with multi-year queues, a growing share of developers are routing around the grid entirely, and the underlying demand driving them to do so is real and still climbing even as the request numbers get inflated.
Behind-the-meter (BTM) generation, on-site natural gas, solar, batteries, fuel cells, and increasingly small modular reactors, now accounts for more than 25% of new data center capacity, according to our white paper research. Chevron's 2.67 gigawatt Texas power plant, built under a long-term agreement to supply a Microsoft data center, is one of the clearest signals yet that power generation is becoming part of the data center business model itself, not just an input to it.
Texas and Pennsylvania have emerged as the leading markets for this approach, thanks to regulatory environments that reward developers willing to bring their own power rather than wait on the interconnection queue.
Cutting through the noise
The phantom demand problem makes one thing clear: headline gigawatt figures are no longer a reliable signal for where data center development is actually viable. As our CEO Yoann Hispa put it in the white paper, "Site selection in this congested market is fundamentally about securing energy sovereignty."
That takes real, site-level data, not aggregate queue numbers that are increasingly disconnected from reality. LandGate's Offtake Capacity data gives developers nationwide, proprietary visibility into actual grid capacity at the interconnection point level, so you can tell a credible site from a phantom one before you commit capital.
