Steelmakers face rising energy costs as AI centers compete for power

The American steel industry, a traditional anchor of industrial power demand, is losing its stable pricing environment to the arrival of artificial intelligence. A report from the Steel Manufacturers Association indicates that the rapid expansion of data centers is driving electricity costs significantly higher, creating a direct competition for power between high-tech infrastructure and heavy manufacturing. For steelmakers using electric arc furnaces to melt scrap, these rising rates represent a structural threat to margins.

At JSW Steel USA’s plant in Mingo Junction, Ohio, executives have warned that the decades-long era of predictable electricity prices is ending. The impact is already measurable. Specialty producer Metallus, based in Canton, Ohio, reports that its annual electricity expenditures have risen by $15 million, an increase of roughly 70 percent since 2024. While the construction of data centers provides a new market for structural steel, the energy required to produce that steel is becoming increasingly expensive. This competition for a finite supply of grid power is forcing industrial operators to reconsider their long-term cost structures in a market where they no longer dominate the demand side.
