A contractor who has never set foot on a data center jobsite is still feeling the effects of the data center boom, whether that shows up as a harder search for licensed electricians, a longer wait on switchgear, or a prefabricated assembly arriving on a truck in place of raw conduit and fittings. EC&M’s 2026 Top 50 Electrical Contractors Special Report, published September 15, along with a companion editorial published a few days earlier, lays out just how dominant that single market has become across the trade.
The Numbers Behind the Boom
The scale of the shift shows up clearly in EC&M’s Top 50 report, which tracks the country’s largest electrical contracting firms.
| Metric | 2025/2026 Figure | Change |
|---|---|---|
| Combined Top 50 revenue growth | Up 35% year over year | The largest jump on record for the survey |
| Firms naming data centers a top-3 market | 91% | Up 5 points |
| Firms citing data centers as top electrification driver | 92% | Top-ranked driver this cycle |
| Firms reporting labor shortages | 83% | Up 9 points year over year |
| Firms citing AI as a major part of current work | 28% | Down from 42% the year before |
Wire and cable saw the sharpest cost increases among materials, and switchgear, transformers, and generators carry the longest lead times of any major equipment category.
Why It Reaches Beyond Data Center Sites
Data center demand doesn’t stay contained to the firms building hyperscale campuses. Chief economist Anirban Basu’s analysis, cited in EC&M’s coverage, found that nonresidential construction spending growth in July 2026 was driven entirely by data center activity, pulling skilled labor, wire and cable, and switchgear away from every other commercial and industrial job competing for the same crews and the same materials.
The Prefab Pivot: A New Core Skill
Nearly every firm surveyed reported growing use of off-site prefabrication, with roughly 60 percent calling it a significant shift rather than a minor adjustment. One example from the report: a prefabricated conduit-support assembly cut on-site install time by about eight hours on a hospital job. Receiving, verifying, and commissioning prefab assemblies is becoming a core field skill rather than a specialty one, and crews should expect more of it regardless of what market they’re working in.
A practical checklist for a crew receiving a prefabricated assembly for the first time:
- Confirm the assembly matches the shop drawing before it leaves the truck, not after it’s mounted.
- Inspect conduit, fittings, and terminations for shipping damage before installation begins.
- Verify labeling and circuit identification match the panel schedule.
- Document the commissioning steps actually performed on site, since prefab doesn’t remove the need for a paper trail.
Field Tech Becomes Standard Issue
Safety and compliance apps, along with BIM and VDC coordination software, are now the leading uses of jobsite technology, ahead of the AI tools getting most of the industry buzz. Field apps and software rank as a top training priority for 2026 and 2027, which makes basic comfort with a tablet or phone-based coordination tool as necessary as reading a print used to be.
Material Lead Times: Plan Earlier
Long lead times on major equipment mean project managers need to lock in orders earlier than the schedule might suggest is necessary:
- Wire and cable pricing has climbed the most of any material category tracked in the report.
- Circuit breakers and breaker panels should get flagged in early project planning rather than ordered on the usual schedule.
- Switchgear, transformers, and generators carry the longest waits of any equipment category, so those orders belong at the very front of a project timeline.
FAQs
Why did Top 50 electrical contractor revenue jump 35% in one year?
Data center construction drove the increase, with 92% of surveyed firms naming it their top electrification driver and 91% listing it as a top-3 market.
Does the data center boom affect contractors who never work on data centers?
Yes. It pulls skilled labor and materials like wire, cable, and switchgear away from every other commercial and industrial project competing for the same resources.
Is AI actually changing daily electrical work right now?
Not as much as the hype suggests. Only 28% of firms called AI a major part of current work, down from 42% the year before, though it remains a training priority looking ahead.
What is driving the shift toward prefabrication?
The ongoing labor shortage, with 83% of firms reporting shortages, is pushing firms to shift more assembly work off-site to make better use of the electricians they do have.
What should a tech check when a prefab assembly arrives on site?
Confirm it matches the shop drawing, inspect for shipping damage, verify labeling against the panel schedule, and document the commissioning steps actually performed.
Which materials have the longest lead times right now?
Switchgear, transformers, and generators carry the longest waits among major equipment categories, according to the EC&M report.
Should smaller firms worry about this trend if they don’t bid data center work?
Yes, since labor availability and material costs are shared across the whole market, even firms with no data center clients feel the ripple effects.
What jobsite technology is actually getting used day to day?
Safety and compliance apps and BIM or VDC coordination tools lead current jobsite technology use, ahead of AI-specific tools.
Is the labor shortage specific to electricians or broader across the trades?
The EC&M report specifically names electricians as the hardest role to fill, with nearly all surveyed firms hiring in 2025 and planning to hire more in 2026.

Staying Current
Data centers are pulling the electrical trade in their direction: stronger revenue, tighter labor, longer waits on switchgear, and prefabrication moving from novelty to standard practice. A firm does not need a hyperscale contract to feel the effects.
