Capacity
500 kpph steam
330 mmbtu/hr hot water
Project Description
United States Steel (formerly
National 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 USS's Midwest Plant operations.
Commercial Operation
September 1997
Benefits
The CHP facility supplies 100% of the thermal energy needs and the
majority of the electical 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 regional emissions by an average of 1,500 tons of NOx,
2,500 tons of SO2, and 380,000 tons of CO2 per year.
