The Invisible Cornerstone of Data Centers: When City Competition Shifts to Talent Infrastructure

In the suburbs of Ashburn, Virginia, the roar of excavators mingles with the low hum of servers to form a new urban backdrop. Once the domain of apple orchards, this area has now become a physical hub of the global internet—dozens of data centers have risen, each night blinking with blue indicator lights, like silent power stations. Yet what truly keeps urban planners awake at night is not the energy consumption of these buildings themselves, but where the people who build them come from.

Lightcast's latest Data Centers and Local Workforce Report reveals a counterintuitive truth: even when land, electricity, capital, and political will are all in place, the availability of labor is the ultimate variable determining project success or failure. "You need power infrastructure, but you also need labor infrastructure," emphasized Josh Wright, Vice President of Growth at Lightcast, in a press release. This statement sounds like a management cliché, but in the data center industry, it is becoming a harsh reality.

Fleeting Boom and Permanent Void

The lifecycle of any data center can be clearly divided into two phases: construction and operation. And these two phases have vastly different impacts on a city's labor market. The report shows that the short-term construction phase requires 1,000 to 10,000 workers, while the long-term operational phase only needs 50 to 400 permanent employees. For example, a PwC data center completed in 2023 brought about 5,000 jobs during construction, but retained fewer than 300 people during operations; similarly, a 2024 JLARC project employed 4,000 people during construction, but that number plummeted to 200 during operations.

What does this mean? For a city, a data center is more like a feast than a long-term employment contract. Thousands of construction workers flood in, needing accommodation, meals, and consumer spending, driving short-term booms for local restaurants and hotels. But once the servers start running, they pack their tools and head to the next construction site. As Wright said: "Community leaders must ask themselves whether the short-term stimulus is worth the investment, because those people will eventually leave."

This pattern repeats in the suburbs of Portland, San Jose, and Northern Virginia. After local residents reap a wave of income, what is left behind is often empty temporary apartments and a building that requires little manpower to maintain. Cities need to provide temporary housing and public services for these workers, yet they cannot obtain a commensurate long-term tax base return.

Global War for Skilled Workers

Even if we accept this short-term boom, another question follows: do we have enough welders, electricians, HVAC engineers, and project managers to complete these projects?Even if we accept this short-term boom, another question follows: do we have enough welders, electricians, HVAC engineers, and project managers to complete these projects? Lightcast data shows that global job postings for data center construction roles have doubled over the past two years. In the six months from September 2025 to February 2026, construction job postings related to data centers increased by 23% compared to the previous six months. Demand for data center technicians and engineers has risen by a similar margin.

But these skilled trades have long been in short supply. Previous Lightcast research found that the annual shortfall of skilled tradespeople in the United States exceeds 1.7 million. You're not just competing with other data centers for the same electrician—you're also competing with commercial real estate, residential projects, and infrastructure projects for the same pool of workers. When a company tries to hire electrical installers for a data center project, it is effectively entering a bidding war with no end in sight.

In Austin, Texas, some construction firms have begun offering signing bonuses and hourly wages 30% above the industry average to attract welders; in Mesa, Arizona, enrollment in the local community college's data center operations certificate program has surged, but students need at least 18 months to graduate. Yet a project timeline is often only 24 months. That time gap alone is enough to stall the entire investment.But now, competition among cities is also reversing—not only for the capital of tech companies, but also for those who can build and maintain digital infrastructure. Cities that invest in apprenticeship programs, vocational education, and skills certification will win tickets to the next round of the digital economy. And communities that ignore this will only see those blue indicator lights turn on while realizing they have already been quietly bypassed.
