Electrical subcontracting can account for 45% to 70% of a typical data center’s construction budget, according to the International Brotherhood of Electrical Workers.

That number helps explain what is happening to the electrical trade right now. When a project type this heavily dependent on electrical work begins scaling nationally, it does not simply add demand. Data center projects can compete directly with residential and commercial contractors for experienced electrical workers.

If you run an electrical business or are working toward a license, this is worth understanding as a broader market shift rather than simply another labor-shortage headline.

At a Glance: The Electrical Labor Picture in 2026

Annual openings: The U.S. Bureau of Labor Statistics projects about 81,000 electrician openings per year, on average, through 2034.
Growth rate: Electrician employment is projected to grow 9% from 2024 to 2034, compared with 3% for all occupations.
Aging workforce: Reuters reported in May 2026 that almost one in five electricians is age 55 or older.
Data center demand: Electrical subcontracting can account for 45% to 70% of a typical data center’s construction budget, according to the IBEW.
Training pipeline: Applications for commercial electrical apprenticeships reportedly increased by more than 70% between 2022 and 2024, according to Validated Insights data cited in recent reporting.

The Squeeze Is Structural, Not Cyclical

Two things are happening at once, and they push in the same direction.

On the supply side, the electrical workforce is aging. Reuters reported in 2026 that almost one in five electricians is already 55 or older. On the demand side, the Bureau of Labor Statistics projects electrician employment to grow 9% from 2024 to 2034 and estimates about 81,000 openings each year, on average, over the decade.

Importantly, those 81,000 openings are not all newly created jobs. BLS says many are expected to result from workers transferring to other occupations or leaving the labor force, including retirement.

That combination of growth and replacement demand creates a workforce challenge that may persist even as individual construction markets rise and fall.

Data Centers Are Competing for Your Crew

The demand side has a specific driver: the rapid expansion of data centers and AI infrastructure across the United States. These projects require significant electrical capacity and large numbers of skilled workers to build and maintain it.

The International Brotherhood of Electrical Workers estimates that 45% to 70% of the construction cost of a typical data center goes to the electrical subcontractor. That puts electricians at the center of the current data center construction boom.

That demand is colliding with an already tight labor market. Reuters reported in May 2026 that the U.S. data center boom is intensifying shortages of electricians and other skilled power-sector workers. Nearly one in five U.S. electricians is already age 55 or older, while BLS projects approximately 81,000 electrician openings each year through 2034.

Microsoft has identified the national shortage of skilled electricians and pipefitters as perhaps the single biggest challenge for U.S. data center expansion. The company estimates that the United States will need to recruit and train half a million new electricians over the next decade to meet the country’s growing electricity needs.

For a regional commercial electrical contractor, the practical effect is significant: your labor market increasingly includes large infrastructure and data center projects that may not compete for your customers, but do compete for experienced electricians.

That can make qualified workers harder and more expensive to recruit and retain, particularly as demand grows for electricians with the experience and credentials required to work on complex commercial and mission-critical electrical systems.

What This Changes If You Run the Business

Three practical consequences are worth planning around.

Bid pricing: Labor availability can become just as important as material pricing when determining what work you can realistically commit to. Bids based on historical staffing assumptions may carry additional risk when experienced electricians are difficult to recruit.

Schedule risk: Crew availability needs to be treated as a scheduling input. Taking on work without a realistic staffing plan can increase the risk of delays.

Retention economics: Investing in apprentices and helping employees progress toward higher-level credentials may become increasingly valuable when experienced replacement hires are difficult to find.

What This Changes If You Are Working Toward a License

The training pipeline is responding. Applications for commercial electrical apprenticeships increased by more than 70% between 2022 and 2024, according to Validated Insights data cited in recent reporting on the electrical workforce pipeline.

But more applicants entering the pipeline cannot close the experienced-worker gap immediately. The Bureau of Labor Statistics notes that most electricians learn through an apprenticeship, meaning it takes time for new entrants to develop the experience needed for higher-responsibility work.

That makes experience and licensure increasingly important. Depending on the jurisdiction and type of work, obtaining the appropriate license can expand the work an electrician or electrical contractor is legally qualified to perform, supervise, or contract for.

The opportunity: Entering the trade and becoming an experienced, appropriately licensed electrical professional are two different stages. As demand for skilled electrical labor grows, completing the licensing path can position contractors for a broader range of opportunities.

Where Licensing Can Expand Your Opportunities

If you already hold an electrical license and are considering where to expand, two directions are worth weighing.

The first is geographic. Data center construction is concentrated in particular markets, and qualifying for electrical licenses in additional jurisdictions may put contractors within reach of more projects.

The NASCLA Accredited Electrical Examination Program offers three open-book electrical trade examinations: Electrical Contractor/Master Electrician, Journeyman Electrician, and Residential Electrical Contractor. Contractors who pass a NASCLA Accredited Examination may use the result in lieu of a state-specific trade exam in participating jurisdictions, but candidates must still follow each licensing agency’s application policies and meet any additional requirements.

NASCLA also makes clear that its examination program is not a national license. Acceptance varies by participating agency and exam classification.

The second direction is scope. Contractors with experience in complex power distribution and other electrical systems required by large commercial and mission-critical facilities may be better positioned to pursue opportunities created by data center construction than contractors focused solely on standard commercial fit-outs.

Where CTC Fits

Contractor Training Center offers electrical contractor exam preparation for a range of state licensing paths, along with NASCLA Electrical Exam Prep for contractors and electricians pursuing the NASCLA Electrical Contractor/Master Electrician, Journeyman Electrician, and Residential Electrical Contractor examinations.

Structured exam preparation can help candidates become more familiar with approved reference materials, practice calculations, improve book navigation, and prepare for the testing format associated with their licensing path.

Frequently Asked Questions

How many electrician openings are projected each year?

The Bureau of Labor Statistics projects about 81,000 electrician openings annually, on average, from 2024 to 2034. These are not all newly created jobs; many openings are expected to result from workers transferring occupations or leaving the labor force.

Why are data centers increasing demand for electricians?

Data centers require extensive electrical infrastructure. The IBEW estimates that electrical subcontracting can account for 45% to 70% of a typical data center’s construction budget, concentrating significant construction demand in the electrical trade.

Is the apprenticeship pipeline closing the electrician gap?

Not immediately. Apprenticeship applications have increased, but new entrants still need time to complete training and gain field experience. That means an increase in applicants does not instantly increase the supply of experienced electricians.

Can a NASCLA electrical exam help with licensing in multiple states?

Potentially. Participating licensing agencies may accept one or more NASCLA electrical examinations in lieu of their state-specific trade exam. NASCLA is not a national license, and applicants must still meet each agency’s additional licensing requirements.

Does becoming licensed guarantee access to data center work?

No. Project opportunities depend on the jurisdiction, license classification, experience, scope of work, employer or business qualifications, and project requirements. Licensure can, however, expand the work a contractor is legally eligible to pursue.
