Americans are rallying against data centers. Surprisingly few are actually getting built
The AI Data Center Boom Faces Reality Check Despite Record Investment
Activelifezero.com – Public sentiment against artificial intelligence facilities has reached fever pitch, with politicians campaigning on platforms promising to halt their construction and voters expressing strong resistance. Yet beneath the headlines about local battles and proposed bans lies a more complex picture: the AI data center expansion is encountering substantial obstacles that have little to do with community opposition.
While the narrative suggests these massive computing facilities are springing up overnight across the country, the actual construction pipeline tells a different story. Building timelines are stretching, material availability is tightening, and power grid capacity is being tested to its limits. The infrastructure needed to support the AI revolution is proving far more difficult to assemble than investors initially anticipated.
Construction Delays Outpace Expectations
The gap between planned and actual delivery has widened considerably. Historically, approximately 72 percent of scheduled data center capacity reaches completion on schedule, but the AI sector is falling behind that benchmark. Only about half of the computing capacity slated for activation through 2028 is projected to materialize by its target date, creating potential bottlenecks for companies counting on this infrastructure.
Traditional data center construction requires 18 to 24 months from groundbreaking to operation, but those windows are expanding as supply chain disruptions and labor constraints compound. Even with $750 billion in AI infrastructure commitments this year alone, many projects remain stuck in planning phases rather than breaking ground.
JPMorgan analysis reveals that 60 percent of data center capacity scheduled for 2027 completion has not yet begun physical construction. An additional 7 percent of projects that have started have experienced subsequent delays, pushing completion dates further into the future.
The Scale of Planned Expansion
The ambition behind the current wave of data center development is unprecedented. The United States contained 5,427 data centers at the close of last year, according to Stanford University's AI Index Report. AI companies have now announced intentions to construct 3,969 additional facilities across the country, nearly doubling the existing count.
However, only 802 of those planned facilities are currently under construction. Skepticism exists about how many of these nearly 4,000 projects will actually materialize. Developers routinely submit multiple applications across different regions simultaneously, selecting only the most feasible options after evaluating regulatory environments, power availability, and construction costs.
Two-thirds of the pipeline is implausible. We expect just 180 gigawatts of the 565 gigawatts currently planned to actually get built over the next decade.
Stijn Van Nieuwerburgh, a real estate professor at Columbia Business School, characterized the majority of announced projects as unrealistic given current constraints. The total investment commitment of approximately $10 trillion represents 50 percent more spending than the nineteenth century railroad expansion, the largest infrastructure boom in American history.
Supply Chain Bottlenecks Threaten Timelines
The overwhelming demand for data center construction has created cascading shortages across multiple sectors. Building materials have become difficult to source as demand surges beyond historical norms. Even when structural components are available, the specialized chips housed inside these facilities face their own supply constraints.
Taiwan's TSMC manufactures virtually every leading AI chip, including Nvidia's Blackwell and AMD's MI300X processors. This concentration makes the company a single point of dependency in the global AI supply chain, according to Stanford's AI Index report. Any disruption at TSMC could ripple through the entire industry.
Power infrastructure presents equally significant challenges. Data centers currently consume roughly 8 percent of United States electricity, a figure projected to reach 12 percent by 2028 according to the American Edge Project, an advocacy organization supporting AI facility development.
Many AI companies have responded by building their own electricity generation facilities, but this strategy encounters its own obstacles. Wait times for generation step-up transformers have tripled, according to JPMorgan. GE Vernova, the largest natural gas turbine manufacturer, reported that bookings for its power generators doubled to $200 billion over a five-year period.
Inflation for transformers and power regulators has surged to the second highest level among all 47 categories tracked by the Bureau of Labor Statistics in its monthly Producer Price Index, reflecting wholesale price pressures throughout the supply chain.
Labor and Regulatory Headwinds
Meeting construction deadlines requires substantial workforce expansion. The American Edge Project estimates that the United States needs to add 500,000 electricians, 300,000 welders, and 550,000 plumbers to complete all proposed data center projects on schedule.
Recent immigration policy modifications have complicated labor recruitment efforts. Contractors operating around the clock face challenges when skilled workers remain tied to existing projects rather than available for new construction.
Some of our clients are developing 24/7/365, and contractors are moving around all day, but there's nothing they can do if all the labor is tied up in existing projects.
Joe Macejak, head of Marsh Risk's United States property digital infrastructure business, highlighted how labor constraints can stall even well-funded projects.
Public opposition has also intensified, with approximately a dozen states proposing data center building moratoriums. New York and Texas lead this effort, though these regulatory challenges represent only one layer of difficulty in an already complex construction environment.
Implications for the AI Industry
These construction delays carry significant implications for artificial intelligence development timelines. Companies that have committed to aggressive deployment schedules may need to adjust expectations or explore alternative solutions such as cloud-based capacity or international expansion.
The gap between announced plans and actual delivery could also affect investor confidence and valuation models. Projects that appear viable on paper may require additional financing or extended timelines to complete, potentially increasing costs for all stakeholders.
As the industry navigates these challenges, the companies that successfully secure materials, power, and labor will likely gain competitive advantages. The data center boom may ultimately prove more selective than initially anticipated, with only the most feasible projects reaching completion in the coming years.
