AI data center energy boom drives up factory power bills across the Rust Belt

Steelmakers and brick factories across the Rust Belt are facing an unexpected squeeze on their bottom lines as surging power consumption from AI data centers strains regional electricity supply. The sharp rise in energy costs threatens to undercut President Trump's push to revitalize domestic manufacturing—even as his administration has backed the tech companies fueling the data center expansion.

The Cost Surge#

Factory electricity bills are climbing faster than those for other customer categories, according to Reuters analysis. Belden Brick Company, an Ohio-based manufacturer with 141 years of history, saw its monthly electricity charges jump from $1,600 to $12,000—a shift driven by rising capacity rates in the 13-state region served by PJM Interconnection, the country's largest grid operator.

The steel industry has been hit particularly hard. According to industry data, US steelmakers across PJM's territory are absorbing tens of millions of dollars in extra annual power costs. Since electricity represents 20–40 percent of steel production expenses, these increases directly threaten profitability. Metallus, an Ohio-based producer, reported a 70 percent jump in electricity costs since 2024, translating to $15 million in additional annual spending.

Why Data Centers Are the Culprit#

The explosion in AI infrastructure has fundamentally reshaped regional power demand. Capacity charges in PJM's market—fees paid to generators based on supply and demand forecasts—have skyrocketed from $28.92 per megawatt-day in 2024 to $329.17 per megawatt-day in 2026. States across PJM territory have aggressively courted large-scale AI data center projects that require enormous amounts of continuous power.

Steel production itself is energy-intensive. Each electric arc furnace used in steelmaking draws between 40 and 200 megawatts at any given moment, and the entire US steel industry peaks at 11 gigawatts across all facilities combined.

A Mixed Legacy#

The data center boom has delivered some benefits to domestic steelmakers. AI infrastructure construction alone requires an estimated 1 million tons of steel annually, providing sustained demand for manufacturers. Yet that advantage is being overwhelmed by the cost side of the equation. The same growth that has generated new orders has also driven up the price of the electricity that steels mills depend on to operate.
