MADISON, Wis., May 2, 2013 /PRNewswire/ --Wisconsin Power and Light Company

install additional emission control technology at Edgewater Generating Station
Unit 5 in Sheboygan, Wisconsin.

"Edgewater Unit 5 has always been a strong and efficient energy source for WPL
customers," explained John Larsen, President – WPL. "Installing these
additional emission controls positions it to continue that service and deliver
on our environmental commitment as we transition our generating fleet to meet
our customers' energy needs in a safe, reliable and cost effective manner."

Pending a written order from the PSCW, today's decision authorizes WPL to
install a scrubber and baghouse system, which will reduce sulfur dioxide
emissions from Unit 5 by approximately 90%, with the co-benefit of
significantly reducing emissions of fine particulate matter.

WPL expects to begin construction of the project in 2014 and place it in
service in 2016. The estimated project cost approved by the PSCW is
approximately $410 million excluding AFUDC. This project is expected to create
as many as 400 jobs during peak construction.

Wisconsin Power and Light Company (WPL), based in Madison, Wis., provides
electric service to approximately 460,000 customers and natural gas service to
approximately 180,000 customers in more than 600 communities across central
and southern Wisconsin. WPL is committed to providing the energy and
exceptional service its customers and communities expect – safely, reliably,
and affordably. WPL is a subsidiary of Alliant Energy Corporation, for more
