What Powers Data Center Construction?

Ask most people what data center construction involves, and they'll picture steel beams, server racks, and rows of cooling units. That picture only covers the surface.

Behind every hyperscale campus sits a web of industries working in lockstep long before the first concrete pour. There are nuclear engineers negotiating power purchase agreements, manufacturers producing switchgear and transformers on backlogged production lines, and utility crews racing to bring new power generation online.

Data center construction has become one of the most interconnected undertakings in modern industry and understanding that web is useful whether you're an organization trying to staff a project or a candidate wondering where your background fits.

Data Center Construction Doesn't Happen in a Vacuum

The scale of today's buildout explains why so many industries are getting pulled in at once.

The Scale of the Problem

The pace of data center development right now is hard to overstate. Goldman Sachs Research projects US data center power demand will roughly double, climbing from 31 gigawatts in 2025 to 66 gigawatts in 2027. That kind of growth touches nearly every industry tied to electricity, construction, and heavy equipment.

Why One Industry Can't Do It Alone

Numbers at that scale can't be met by data center developers alone. They depend on energy producers, equipment manufacturers, and a skilled trades workforce large enough to put it together on schedule. Every one of those industries is short on people right now, which is why data center construction has become as much a staffing challenge as an engineering one.

The Skilled Trades Behind Every Build

Every project starts with people on the ground, and right now there aren't enough of them.

A Widening Labor Gap

Long before a data center goes live, it needs electricians, HVAC technicians, mechanical pipefitters, and commissioning engineers on-site, often for years at a stretch. The Associated Builders and Contractors estimates the US construction industry needs roughly 349,000 additional workers in 2026 alone, a number expected to climb in 2027. Data center-specific projects add further shortages on top: some industry estimates put unfilled data center construction and operations roles at 340,000 by the end of 2026, out of roughly 650,000 total positions needed.

What This Means for Employers & Candidates

Journeyman electricians and MEP engineers are consistently the hardest roles to fill, with specialized vacancies sometimes taking months to close. For employers, that gap is worth treating as a fixed part of your timeline, not a mid-project surprise. If you're a candidate in the trades, experience on mission-critical, high-density construction sites is currently one of the most sought-after skill sets in the market.

Why Energy Jobs Are the Other Half of the Equation

Construction crews can only build what the grid can actually power.

Power Demand Is Outpacing Supply

None of this matters if the power isn't there to run it. EPRI projects US data centers could consume 9% to 17% of the country's total electricity by 2030. To keep pace, utilities are entering multi-year capital plans worth hundreds of billions of dollars for new generation, transmission, and grid interconnection work.

A Shared Labor Pool with Power Companies

That buildout is driving a parallel hiring wave in energy jobs: line workers, power plant operators, grid engineers, and project managers who can move fast enough to match data center timelines. In practice, many of these roles draw from the same limited talent pool as data center construction itself, which means energy companies and developers are often competing for the same candidates rather than filling separate needs. Explore our Energy Jobs Report for a closer look at where that demand is concentrated.

Nuclear Jobs and the Staffing Race Behind Them

Nuclear has become one of the fastest-growing pieces of the data center power puzzle, and its workforce is scrambling to keep up.

The Hyperscaler Nuclear Rush

Nuclear has become a preferred solution for operators chasing reliable, round-the-clock electricity, and hyperscalers have moved fast to lock it in. Meta has committed to securing up to 6.6 gigawatts of nuclear power by 2035. Microsoft is bringing a shuttered reactor back online. Google and Amazon have both signed early-stage agreements with small modular reactor developers. Behind every deal sits a workforce question.

A Workforce That Can't Keep Up

The nuclear energy sector employed roughly 67,900 workers in 2024, and the Department of Energy's latest US Energy & Employment Report found employers anticipating a 9.2% increase in the nuclear construction workforce, even before newer federal policy aimed at expanding domestic nuclear capacity took effect. Postings for licensed operators and nuclear engineers have climbed sharply industry-wide as utilities and developers race to staff up ahead of these builds.

The Nuclear Energy Staffing Challenge

Demand for licensed operators, health physicists, and construction trades with nuclear experience is rising faster than the pipeline of qualified nuclear jobs candidates can fill, particularly with Nuclear Regulatory Commission licensing timelines that run 18 to 24 months. Nuclear energy staffing has quietly become one of the tightest, most overlooked specialties in the data center ecosystem.

For employers, that means starting the search well ahead of a typical construction timeline, since qualified nuclear talent is rarely available on short notice. For candidates with plant operations or nuclear engineering experience, it means unusually strong leverage in a market that badly needs what you already know how to do. Read our Nuclear Jobs Report 2025 to see how that demand is playing out across openings.

Manufacturing Jobs and the Data Center Supply Chain

None of this gets built without the equipment behind it, and that equipment has its own labor problem.

A Supply Chain Built on Specialized Components

Every data center is, in a real sense, an assembly of specialized manufactured components: semiconductor chips, switchgear, transformers, generators, and cooling systems, most produced in a small number of facilities with limited spare capacity. Rabobank's research into the data center supply chain notes that because these components share critical inputs and suppliers, a shortage in one area cascades rather than stays contained, extending lead times and inflating costs before equipment ever reaches a job site.

The Manufacturing Talent Gap

Filling manufacturing jobs fast enough to keep that supply chain moving is its own challenge. Manufacturers across the electrical equipment, semiconductor, and heavy machinery space are reporting the same story: too few skilled workers to meet demand, and lead times that stretch even longer as a result.

For candidates with a manufacturing background, that shortage means real opportunity across an expanding set of employers who may not obviously connect to data centers on the surface.

For organizations, it means sourcing manufacturing talent early, often before a single piece of equipment is scheduled to ship. See our 2025 Manufacturing Jobs Report for current supply chain-related openings.

One Shared Talent Pool

The throughline across every industry above is that they're all drawing from an overlapping, shrinking talent pool. The same electricians, engineers, technicians, and project managers who could staff a utility-scale power project are often qualified for data center construction roles, and vice versa.

For employuers, that means the smartest sourcing strategies look across adjacent industries rather than searching within construction alone. For candidates, it means experience in energy, nuclear, or manufacturing work is rarely as far from data centers as it looks on paper. That overlap is why data center construction can't be staffed one industry at a time: a single project timeline depends on nuclear, energy, manufacturing, and skilled trades talent all being available at once, not in sequence.

Building the Team Behind the Build

Whether you're an organization staffing a multi-year data center construction project or a candidate deciding where your background fits, the takeaway is the same: this industry rewards those who understand how these pieces connect. A background in nuclear operations, grid engineering, industrial manufacturing, or specialized trades has a place in data center development, often in ways that aren't obvious from a job title alone.
