Alliant Energy Receives Final Approval to Upgrade Columbia Energy Center

Alliant Energy’s Wisconsin utility and its co-owner utility partners
have received final regulatory approval to upgrade the coal
pulverizers and steam turbines at the Columbia Energy Center.
The upgrades approved by the Public Service Commission of
Wisconsin will help lower operating costs and improve the
efficiency and reliability of the generating station located near

“This project will provide direct benefits to customers and
is part of our overall energy resources strategy that puts a
priority on investing in our newer and larger generating
units,” according to John Larsen, President of Alliant
Energy’s Wisconsin utility.


The Columbia Energy Center upgrade project includes replacing
twelve pulverizers and upgrading two steam turbines installed
when the plant was constructed in the 1970s.  Installing this
newer technology is designed to increase the plant’s operating
capacity by nearly 10 percent, bringing more low-cost electricity
to utility customers. Construction of the project is expected to
begin in 2015, with an anticipated completion in 2017.  The
investment in new technology and equipment is expected to be
approximately $130 million and will be shared by Alliant Energy’s
Wisconsin utility and the co-owners: Madison Gas and Electric
Company and Wisconsin Public Service Corporation.
