Interstate Power and Light Announces Technology for New Power Plant

 
 

New unit will be able to burn biomass, provide co-generation opportunity



    CEDAR RAPIDS, Iowa, April 9 /PRNewswire-FirstCall/ -- Interstate Power
 and Light Co. (IPL), a subsidiary of Alliant Energy Corporation (NYSE:   LNT)
 decided to utilize super-critical pulverized coal boiler technology at its
 new generation facility planned for Marshalltown, Iowa. It offers IPL's
 customers affordable and reliable electricity and also boasts increased
 efficiencies over traditional plants. Those efficiencies provide a
 reduction in greenhouse gas emissions.

     "Our plant design team was charged with finding an environmentally
 responsible technology that was also reliable and affordable for
 customers," explained Kim Zuhlke, vice president of new energy resources
 for Alliant Energy. "Customers can be assured that we're building a plant
 using the best available proven boiler technology. It's highly efficient,
 meaning it takes less coal to produce power. That means lower emissions and
 fuel costs."
     Many factors were considered in selecting technology, and each site is
 different. To reduce risk to customers and shareowners, the utility focused
 on efficient technologies that are already in commercial operation and also
 focused on available fuels and available delivery methods.
     IP&L's plans call for the boiler to be designed to burn biomass fuels,
 such as switchgrass. Provisions are also being made to allow for
 co-generation. Co-generation allows a portion of the steam created during
 electric power production to be exported to a nearby facility, providing a
 future economic development opportunity for Marshalltown.
     IP&L project team members continue to pursue and review the best
 available control technology to further reduce air emissions. Those
 controls will ensure the plant can meet stringent air emission standards,
 and will reduce particulate, NOx, SO2 and mercury emissions as regulated by
 the Iowa Department of Natural Resources and federal regulators.
     Design work on the new plant continues and permitting and regulatory
 approval efforts are underway. The plant is expected to produce
 approximately 600 MW of electricity. IP&L expects to utilize at least 250
 MW of that output and make the remaining capacity available to other
 utility partners. IP&L expects a groundbreaking in late 2008 or early 2009.
 IP&L projects commercial operation of the plant in 2013 or 2014.
