Data Centers Are Running Out of Electricians

The rush to build data centers for artificial intelligence has created one of the tightest labor markets in the skilled trades. Developers can secure land, financing and even power, but they still need hundreds of electricians on each site. Those workers are in short supply, and the gap is spreading to manufacturers, contractors and building owners that need electrical work of their own.

The size of the gap

Associated Builders and Contractors estimates that the construction industry must attract about 349,000 net new workers in 2026, as we covered in our construction workforce report. ABC chief economist Anirban Basu has noted that nearly one in five electricians is 55 or older and that demand for electricians capable of precision wiring has surged because of data center construction.

Union data points the same way. Fortune reported in March that nearly 30 percent of union electricians are between 50 and 70 years old and that about 20,000 electricians are expected to retire each year.

The Associated General Contractors of America has found that the vast majority of construction firms trying to hire report difficulty finding qualified workers, with electricians among the hardest roles to fill.

Why data centers matter

Electrical work makes up a large share of data center construction. Large facilities require extensive power distribution, backup systems and cooling infrastructure. Peak construction can require hundreds of electricians on a single site.

Microsoft president Brad Smith said in March 2026 that the shortage of electricians was the biggest constraint on the company's data center expansion in the United States. Large technology companies plan to spend hundreds of billions of dollars on AI infrastructure this year, and much of that spending depends on electrical labor.

Pay is responding. Indeed economist Sneha Puri reported year-over-year wage growth of 4.6 percent for electricians overall, 6.6 percent for journeyperson electricians, 8.2 percent for apprentice electricians and 9.9 percent for commercial electricians, according to a July report in Insurance Journal.

The ripple effect

The competition affects employers far beyond data centers. Manufacturers need industrial electricians and maintenance technicians to keep production lines running. Hospitals, universities and commercial buildings need electricians for ongoing maintenance. Residential contractors compete for the same workers.

When data center projects pay premium wages, other employers either match or lose workers. Manufacturers already face a wide skills gap, as we explained in our manufacturing workforce report, and electrical maintenance roles are among the hardest to fill.

Training takes time

Electricians cannot be produced quickly. A typical inside wireman apprenticeship requires about 8,000 hours of on-the-job training plus classroom instruction, usually over four to five years. Apprentices are paid throughout, and tuition is often covered.

That timeline makes long-term planning essential. Employers that start apprentices now will have journeyworkers in 2030 or later. Those that wait will compete for a limited pool of experienced electricians at ever higher wages. Our guide to Registered Apprenticeship explains how employers can build programs.

What employers can do

Partner with training providers. Community colleges, union training centers, ABC chapters and NCCER-accredited programs all train electricians. Employers can sponsor apprentices, provide equipment or offer instructors.

Reach younger workers earlier. High school career academies and pre-apprenticeship programs introduce students to the trades before they choose other paths. In Louisville, the Academies of Louisville connect students with employers in construction and manufacturing, as we describe in our report on the Academies of Louisville.

Retain experienced workers. Senior electricians are valuable not only for their own work but for training others. Flexible schedules, mentoring roles and phased retirement options can keep them on the job longer and help transfer their knowledge.

Watch pay ranges closely. With wages for apprentice and commercial electricians rising quickly, employers that set pay once a year may fall behind within months. Reviewing market rates each quarter for hard to fill trades helps prevent losing workers to competitors.

Support licensing. Paying for exam preparation and license fees helps apprentices finish and signals that the employer is invested in their careers.

Look beyond traditional candidates. Military veterans, career changers and workers from related trades can make strong apprentices. Skills-based hiring, described in our report on degree requirements, helps employers evaluate potential rather than credentials alone.

The demand for electrical work is unlikely to fade soon. Employers that invest in training now will be better positioned than those that rely on finding experienced electricians in an increasingly crowded market.
