Michigan's Data-Center Boom Is Quietly Raising What You Pay for Power, Parts, and People

The Stargate megaproject going up in Saline will reshape the cost of doing business for every trades shop in metro Detroit — including the ones that never bid a data center in their life. Here's how the squeeze actually reaches your bottom line.

If your electric bill went up this year and you couldn't figure out why, you are not imagining it, and it is almost certainly not your fault. On March 5, the rate DTE charges for electricity climbed again — the latest in a five-year run where Michigan regulators have approved roughly $1 billion in rate increases for the state's two biggest utilities. The official explanation is "reliability" and "infrastructure." The quieter explanation is sitting on 575 acres of former farmland south of Ann Arbor.

It's called Stargate — locals know it as "The Barn," for the red barn preserved at the entrance — and at $16 billion it's the single largest economic investment in Michigan's history. Oracle and OpenAI are behind it: three server halls on 250 acres of former farmland, operational by early 2028. It will draw 1.4 gigawatts of electricity — roughly the appetite of a million homes — from the same grid that powers your shop, your house, and every job site you run. At full build it lifts DTE's entire system demand by about 25%.

The deal that decides who pays to feed it — the tech company, or everyone else on the grid — was handed to regulators heavily redacted. Michigan's Attorney General fought to open the contracts and was denied. She did not mince words about the process.

"I have never seen, in the long history of the state, a process so secretive, rushed, and ripe for disaster as what the Commission rammed through."

That's the part most coverage stops at: a hidden wealth transfer, dressed up as progress, with you on the wrong end of the power bill. It's true, and it's worth being angry about. But the electric bill is the smallest way this project is going to touch your business — and the rest of it, almost nobody is explaining.

Part One · The Parts

The gear you order every week is now competing with a hyperscaler

A facility like Stargate doesn't just need electricity — it needs the hardware that moves electricity: transformers, switchgear, breakers, miles of copper, rooftop units, chillers. A single hyperscale campus can swallow dozens of large transformers, each costing up to $250,000 and weighing more than 100,000 pounds. When that demand lands on a supply chain that was already tight, everyone downstream feels it.

Here's the part that should stop a Detroit contractor cold: of all the equipment classes, the one analysts expect to get worse is the pad-mount distribution transformer — the everyday gear that energizes a strip mall, a new clinic, a subdivision, a light-commercial build. That's not hyperscaler hardware. That's your hardware. When transformers become "a form of currency" and the players who can pre-buy years of inventory win the schedule, the small shop ordering one unit for one job goes to the back of the line — and pays more when its number comes up.

To be straight about what's proven and what's coming: no Washtenaw contractor has yet gone on record blaming Stargate for a specific parts delay. But the national supply chain that feeds every Detroit distributor is already documented buckling under exactly this kind of demand — and Michigan just added one of the single largest draws in the country to it.

Part Two · The People

Your next hire just got a 30% raise — to work somewhere else

The build needs bodies even more than it needs boxes. The country is already short an estimated 439,000 skilled-trades workers, with construction unemployment at a record-low 3.2% — there is no bench. Into that, data-center work walks in offering 25–30% above standard construction pay, six-figure packages, and perks the trades have never seen. As one staffing analyst put it, a project like this is "a region-changing event that can instantly exhaust local talent pools."

Labor — not demand — has become the binding constraint. More than 80% of firms can't fill the roles they have, and some are turning down work they can't staff.

Locally, the numbers are concrete. The Barn is being built union — the first site under a landmark OpenAI–NABTU agreement — and will employ 2,500+ tradespeople. By the June 1 groundbreaking, more than 700 of them had already logged over 300,000 union hours on the site. Every one of those workers is one not available to the shop down the road.

You don't have to bid a data center to lose this fight. When the Saline site and the Southfield builds pull journeymen toward premium pay, the shops that stay in residential and light-commercial have to overpay to keep a crew — or watch jobs run long because they're short-handed. The poaching doesn't just raise wages on the megaproject. It raises the price of every hospital wing, school, and tenant build-out drawing from the same pool of hands.

On the Ground

This isn't a forecast. It's already happening — and it's already contested.

The Barn broke ground June 1 with the governor on stage; the Saline Township board had voted 4–1 against it before a lawsuit and settlement cleared the way. One state representative called the groundbreaking "a complete betrayal of the working class," and Michigan lawmakers are now moving to repeal the 6% tax break that helped lure the project. Even the people building it frame it as a turning point —

"Stargate Michigan will be the first data center built under NABTU and OpenAI's historic Memorandum of Understanding concerning data center construction."

— Sean McGarvey, President, North America's Building Trades Unions

A real win for organized labor, and for the 2,500 who get the work. But "first" is the operative word — DTE has 7 gigawatts of data-center projects in its pipeline, several more Barns' worth — and every one of them draws from the same finite pool of parts and people that your shop is drawing on right now.
