Mittal Steel
Location
East Chicago, Indiana
Capacity
75 MW electric
Project Description
Mittal Steel (formerly Ispat Inland Inc.) has histoically produced a significant portion of their electricity requirements using onsite generation resources. Primary Energy worked with Mittal Steel to identify an additional opportunity to capture and recycle heat from Mittal Steel's principle blast furnace (No. 7), producing up to 75 MW of electricity.
Commercial Operation
May 1996
Benefits
The North Lake Energy project is capable of supplying more than 20% of Mittal Steel's electricity requirements using an onsite waste fuel that had principally been flared. Primary Energy built and owns the project while Mittal Steel delivers steam from the existing blast furnace gas recovery boilers. This facility has reduced energy costs substantially compared to purchased power alternatives while increasing reliability of the electric energy supply for Mittal Steel's plant operations. In addition, by using previously flared blast furnace gas to produce electricity instead of purchasing the power from the local electric utility, the project reduces regional air emissions on average by 1,300 tons of NOx, 1,500 tons of SO2, and 490,000 tons of CO2 emissions per year.
