Portage, Indiana
Project Description
United States Steel and Primary Energy identified an opportunity to replace an existing onsite boiler house with a state-of-the-art combined heat and power facility (CHP). Primary Energy built, owns, and operates a 63 MW facility that supplies process steam, hot softened water, and electricity to United States Steel's Midwest Plant operations.
Portside Energy, LLC
- Commercial Operation: September 1997
- Customer: United States Steel Corporation
- Location: Portage, Indiana
- Capacity: 63 MW/500 kpph steam/330 mmbtu/hr hot water
- CO2 Reduction: 180,000 tons
Combined Heat and Power (CHP)
Project Benefits
The CHP facility supplies 100% of the thermal energy needs and a significant portion of the electrical energy needs of the Midwest Plant. The combined impact of replacing steam production using natural gas/fuel oil and the simultaneous production of electricity also has the effect of reducing carbon emissions.
The United States Environmental Protection Agency recognized Portside Energy's 2007 operations for high environmental efficiency. The plant produced 180,000 fewer tons of carbon dioxide when compared to other plants using separate heat and power sources.
