ENERGY
We are committed to minimizing our consumption of purchased non-renewable energy. Our efforts include process innovations, transitioning to lower carbon and renewable energy sources and enhancing energy efficiency beyond steelmaking operations.
| Energy (million megawatt hours) | 2025 |
|---|---|
| Energy Consumption – Total Corporation* | 89.75 |
| Energy Intensity1 – Total Corporation* | 5.87 |
Reporting timeframe is January 1, 2025, to December 31, 2025
*Total Corporation includes U. S. Steel and U. S. Steel Košice.
1. Energy intensity is based on the total energy consumption in megawatt-hours divided by the total quantity in metric tons of raw steel produced in North America that is converted into finished steel products.
Entergy Arkansas
In 2025, Big River Steel Works benefited from a full year of renewable power supplied by Entergy’s 250‑MW Driver Solar facility. At Big River 2, solar energy accounted for approximately 21% of total electricity use, with an additional 9% of solar energy allocated to Big River 1 (BR1).
BR1 continued to reduce Scope 2 emissions through the use of renewable energy credits (RECs) provided by Entergy’s Green Promise Tariff. BR1 also participated in Entergy’s Go ZERO program, receiving Alternative Energy Credits (AECs)2 to further offset Scope 2 emissions.
As a result of these initiatives, BR1’s Scope 2 emissions decreased by approximately 15% from 2021 to 2025. In addition, BR1 continued purchasing voluntary RECs through 3Degrees, Inc. as a short‑term measure to further lower Scope 2 emissions.
2. AEC is a certificate corresponding to the environmental attributes of energy produced from clean sources such as nuclear and hydro-electric generation.
Increased Efficiency
To reduce energy costs and reliance on an increasingly strained electricity grid at both the Mon Valley and at Gary Works, we generate our own electricity at the plants using blast furnace offgas. In 2025, we generated 608,250 MWh at Mon Valley, an 11% increase from 2024. That increase in generated electricity reduced our purchased electricity costs by about $4.8 million. Upgrades were made to the boilers and generators at Edgar Thomson, resulting in a 19% increase in electricity generation from 2024 to 2025. Gary Works generated 952,617 MWh of electricity in 2025, a 7% increase from 2024.
