Big River Steel Works (BR1 + BR2)
Large load · 2027 E. STATE HWY. 198, Osceola, AR
Big River Steel Works in Osceola, Arkansas, is U.S. Steel's electric arc furnace flat-rolled campus: the original Big River Steel mill (BR1) and the adjacent Big River 2 (BR2) expansion. With BR2 complete, U.S. Steel says capacity has nearly doubled from three to six million tons a year. The campus is served by Entergy Arkansas, which signed a special rate contract for the original mill in 2015 and said it planned to supply an incremental 550 MW for BR2.
Overview
- Planned demand
- 550 MW
- operating
Entergy Arkansas calls Big River Steel one of its largest industrial customers. In 2015 the utility agreed a special rate contract with the mill and built $73 million of substation and transmission lines to serve it. At BR2's February 2022 groundbreaking, Entergy said it planned to provide an incremental 550 MW to power the new mill on top of its existing supply to Big River Steel. The 550 MW is the utility's stated plan for the expansion. It is not a metered peak, and the original mill's contracted demand has not been published.
Profile
- Original mill: the Flex Mill
- Big River Steel announced in March 2017 that its $1.3 billion mill outside Osceola was complete. It describes itself as a "Flex Mill" that combines integrated-mill grade capability with a scrap-based mini mill. U.S. Steel, which later took full ownership, opened a $450 million electrical steel line on the site in 2023.
- Big River 2
- BR2 was designed with two electric arc furnaces and 3 million tons a year of steelmaking capacity, along with North America's only endless strip production (ESP) casting and rolling line. U.S. Steel said in December 2025 that the expansion was complete, and by March 2026 it described BR2 as complete and online. Entergy's 250 MW Driver Solar farm, approved in 2022, sits next to the campus and was presented as helping U.S. Steel meet its sustainability goals.
