Project Description

Mittal Steel (formerly International Steel Group (ISG)) and Primary Energy partnered to develop additional on-site energy capacity, reducing energy costs and providing a more reliable, secure source of power and steam for Indiana Harbor Works. Mittal Steel needed to retire an existing onsite blast furnace gas recovery boiler and address an opportunity to recover additional blast furnace gas. Primary Energy installed and owns a 50 MW comined heat and power (CHP) facility comprised of a blast furnace gas recovery boiler and a condensing steam turbine.
