St. Louis is building
data centers

Worth training up for in the St. Louis area?
YES means the data centers will need more of that trade than the St. Louis area can spare — so they pay well, pay to train, and run overtime. NO means there are already plenty.
"Short" means the data centers need more of that trade at the busiest point than the area has free to take on new work. Most workers stay on their regular jobs; only about 1 in 4 are free for big new projects like these.
Will the St. Louis area have enough workers?
At the busiest point of the build. Bars to the left mean a shortage (good if you are in that trade). Bars to the right mean workers to spare.
What this means for workers near St. Louis
St. Louis, MO has about 120 MW of AI data centers across 1 site, with 120 MW still to build. The builders here include Contour / TeraWatt / THO Investments.
At the busiest point, about 230 skilled workers will be on these sites at once, across all the trades. Many drive in from nearby towns, but the work starts here — and it is not split evenly, so some trades are short and some are not.
Worth training up for? The work near St. Louis is steady, but the area has enough workers for most trades. Here is the read by trade.
Ironworkers — probably not, just for this. The data centers need about 32 ironworkers, and the St. Louis area already has about 128 free for this kind of work. Plenty. Still steady work, but no special data-center shortage.
Electricians — probably not, just for this. The data centers need about 65 electricians, and the St. Louis area already has about 1,615 free for this kind of work. Plenty. Still steady work, but no special data-center shortage.
Network/low-voltage technicians — probably not, just for this. The data centers need about 14 network/low-voltage technicians, and the St. Louis area already has about 432 free for this kind of work. Plenty. Still steady work, but no special data-center shortage.
Pipefitters — probably not, just for this. The data centers need about 25 pipefitters, and the St. Louis area already has about 1,038 free for this kind of work. Plenty. Still steady work, but no special data-center shortage.
HVAC/R technicians — probably not, just for this. The data centers need about 14 hvac/r technicians, and the St. Louis area already has about 910 free for this kind of work. Plenty. Still steady work, but no special data-center shortage.
Sheet metal workers — probably not, just for this. The data centers need about 7 sheet metal workers, and the St. Louis area already has about 380 free for this kind of work. Plenty. Still steady work, but no special data-center shortage.
These are some of the best-paying jobs you can get without a four-year degree. When a trade is short, builders run overtime and pay to train, and experienced workers can clear $100,000 a year, with health care and a pension through the union. It is the same across the country: builders cannot find enough skilled workers. The U.S. needs about 140,000 more trade workers by 2030 to build all the data centers, and most builders say hiring is their hardest problem. Microsoft's president has called the shortage of electricians the biggest thing slowing data centers down.

"Needed at peak" is the most of that trade working across all the building at the busiest time. "Free to take it on" is how many local workers could move to data-center jobs — about 1 in 4 of the trade; the rest keep their regular jobs. "Short or extra" is the gap. "New data-center jobs" are permanent jobs that stay once a data center opens. "Train up?" is YES when the work needs more than the area can spare (so they pay well and pay to train), NO when there are plenty already. Elevator mechanics are left out of the verdict because their work depends on the building's design.
