88% of Data Center Employers Now Want Medium-Voltage Electricians

Kelly published its 2026 Data Center Salary Guide on August 25, and the finding that matters most to commercial electricians is a single percentage. Eighty-eight percent of the data center employers behind the guide reported high demand for medium-voltage electrical expertise. Only liquid cooling commissioning ranked higher, at 92 percent. GPU cluster operations, the skill the industry talks about most, came in third at 84 percent.

The guide attaches national salary midpoints to the roles that scarcity is repricing. Data center operations leaders sit at $178,000. AI engineers come in at $175,000, which means the people who keep the building energized are benchmarked above the people writing the models it runs. Commissioning program managers are at $135,000, construction managers at $128,000, and data center technician subject matter experts at $112,000. Kelly, a staffing firm reporting $4.3 billion in 2025 revenue and more than 375,000 placements a year, says it built the benchmarks from 18 trillion connected labor data points validated against 8.6 million company pay stubs.

Where the work sits matters nearly as much as what it is. Kelly found a 46-percentage-point spread between the highest- and lowest-paying data center metros. Silicon Valley pays 34.2 percent above the national average and Northern Virginia 16.0 percent above. Chicago is close to par at 1.4 percent above. Then the figures invert: Dallas-Fort Worth is 2.2 percent below the national average, Phoenix 3.8 percent below, Salt Lake City 4.4 percent, Las Vegas 9.2 percent, and Omaha 11.8 percent below. Several of those discounted metros are carrying campuses among the largest under construction in the country.

Set the guide against what the trade pays generally. The Bureau of Labor Statistics puts the 2025 median wage for electricians at $63,190 a year, or $30.38 an hour, across 821,000 jobs. Its Occupational Employment and Wage Statistics release of May 15, 2026, covering May 2025, counted 757,220 electricians and an annual mean of $65,360 for construction and extraction occupations as a group, below the $69,770 mean across all occupations. BLS projects electrician employment to grow 9 percent from 2025 to 2035, adding 75,900 jobs, with about 72,700 openings a year once retirements and exits are counted.

The distance between those two sets of numbers is the whole story. A $112,000 midpoint for a data center technician subject matter expert is not the median electrician's wage with a bonus attached. It is a different labor market that happens to recruit from the same hiring hall, and the entry ticket to it is increasingly voltage class rather than years in the trade.

What changes on the job is the gear and the paperwork that follows it. Uptime Institute's 16th annual global data center survey, released July 28 with more than 800 respondents, found modal rack densities still climbing and a growing number of operators reporting peak densities of 30 kW or higher. Density that high pushes distribution upstream. More capacity is carried at medium voltage and stepped down nearer the hall, which means more unit substations, more switchgear line-ups, more medium-voltage terminations and cable testing, and more of the work landing under qualified-person rules rather than general electrical scope.

Commissioning is where that scope gets validated and where the money concentrates. Kelly's top-ranked skill, liquid cooling commissioning at 92 percent, is not primarily a plumbing problem; it is pumps, controls, and the electrical distribution feeding them, tested in sequence against design intent. That the commissioning program manager benchmark lands at $135,000, above the construction manager at $128,000, is a signal about which phase of a data center build owners consider hardest to staff.

The retention numbers explain why the premiums exist. Uptime found more than half of respondents reporting difficulty finding qualified candidates, with staff turnover persisting as employees move to competing operators. Kelly puts a figure on the same churn: 25 percent of data center personnel get hired away by competitors, and 90 percent of operators identify staffing shortages as a critical constraint on facility development and expansion. Joel Leege, who leads Kelly's science, engineering, technology and telecom business, framed it as a shift in what limits growth: no longer power, land, or equipment, but talent.

The demand behind those constraints is not slowing on any published schedule. Kelly cites $700 billion in projected 2026 capital expenditure from the five largest providers, permanent data center employment reaching 650,000 positions by 2026 against a 2023 baseline 30 percent lower, and more than 180,000 data center construction jobs through 2028. Contractors bidding that work are pricing crews they do not yet have, and owners should expect commissioning schedules to be gated by the availability of medium-voltage-qualified people rather than by gear deliveries alone.

For a commercial electrician already comfortable in 480-volt distribution, the practical read is that the next pay band is one voltage class up, and that it is documented well enough now to negotiate against. For contractors, the same numbers say the shortage has moved from an excuse to a line item.
