July 27 Wisconsin Power and Light Co (WPL), a
unit of Wisconsin power company Alliant Energy Corp,
said it plans to invest more than $1.4 billion in its generating
fleet over the next five years.
WPL's plan includes investing in environmental controls on
its larger and efficient generating units to comply with state
and federal environmental rules.
The company aims to finalize purchase of Riverside Energy
Center, a natural gas-fired combined cycle plant in Beloit,
Wisconsin, by end of 2012 as a part of its investments.
In May, WPL had exercised an option to buy the 600-megawatt
natgas plant for about $392 million from U.S. generator Calpine
WPL also plans to file for additional emission controls for
its Edgewater Generating Station Unit 5 and construct emissions
controls at Columbia Units 1 and 2 and Edgewater Unit 5.
The company intends to retire its three oldest and smallest
coal generating units by the end of 2015.
These units include the 200-MW Nelson Dewey Generating
Station Units 1 and 2, located in Cassville, Wisconsin, and the
60-MW Edgewater Unit 3, located in Sheboygan, Wisconsin.
U.S. power companies plan to shut almost 35,000 megawatts
(MW) of smaller, older coal-fired plants over the next few years
as cheap natural gas prices and stricter environmental rules
have made coal the more expensive option.
