Belden Brick Company has been making bricks in Sugarcreek, Ohio for 141 years. Its products are in the Texas Alamo and Notre Dame University. Last year, its electricity bill surged 90%, and the company's president can tell you exactly where the money went: a single monthly charge that jumped from $1,600 to $12,000.

That charge is called a capacity fee. It is designed to pay power generators for keeping enough electricity available during peak demand, and to fund new supply. For most households, it sits quietly at roughly 10% of the bill. For manufacturers, it can run three times that share. And in the 13-state region managed by grid operator PJM Interconnection, covering a belt from New Jersey to northern Illinois and down to Tennessee, those fees have exploded.

The reason is data centers.

One large server warehouse can consume as much electricity as a mid-sized town. AI companies have been building them across the Rust Belt at speed. Of the eight U.S. states currently considered emerging data center hubs, five sit in the same industrial heartland where factories like Belden Brick operate. The result is a direct collision between two very different kinds of American industry sharing the same grid.

The factories are losing the collision

PJM's capacity fees have surged because supply has stagnated while data center demand has grown fast. Factory electricity costs are rising faster than for homes and most other businesses, according to a Reuters review of energy data and interviews with nearly a dozen manufacturers and industry advocates.

The scale mismatch is stark. A large data center operated by a company like Meta or Amazon can need 50 times more power than even a substantial factory. Yet some proposed policy fixes lump both together as "large power users," potentially making manufacturers pay more to subsidize grid upgrades that primarily serve Big Tech.

Belden Brick has already raised brick prices by 4%. Profits have still shrunk. Company president Brad Belden, fifth-generation family, said local manufacturers may quickly hit limits on what they can absorb. "There are going to be some companies that are on the razor's edge," he said.

Factories facing that edge are weighing their options: raise prices further, slow expansion, or relocate. All three outcomes cut against the Trump administration's stated priority of reviving domestic manufacturing. The White House pointed to tech companies signing a "ratepayer protection pledge" and executive directives to build more power plants in the PJM region, paid for by the tech industry. Whether those steps arrive fast enough to matter is a separate question.

The grid operator itself showed the strain last week. PJM was forced to ask users to cut electricity consumption to avoid rolling blackouts as record-breaking temperatures pushed peak demand to a new high.

A tension the grid was never designed to hold

The data center industry argues its expansion is finally forcing the U.S. to confront long-deferred decisions about grid investment. Aaron Tinjum of the Data Center Coalition said the growth is "making us finally grapple with the difficult decisions that we were always going to have to face." He also cited power-plant retirements and transmission bottlenecks as contributing factors, which is fair. The grid was already under pressure before AI arrived.

But the timing matters. The Rust Belt was supposed to be where America's manufacturing comeback happened. Instead, the factories that stayed through decades of deindustrialisation are now competing for electrons with server farms operated by some of the most valuable companies in the world. The capacity charges function, in effect, as a tax on showing up early and staying put.

If policymakers cannot separate industrial electricity users from hyperscale data centers in the rate structures and the regulatory fixes, the factories absorbing the costs will not wait around for a solution. They will move, shrink, or disappear. That outcome would be neither a grid problem nor a tech problem. It would be a manufacturing problem with no easy reboot.
