Alliant Energy produces electricity and sells electricity and natural gas to customers in Iowa, Minnesota, and Wisconsin - as well as providing transportation and environmental engineering and consulting.

Power Portfolio

Out of its total 7,252 MW of electric generating capacity (0.67% of the U.S. total), Alliant Energy gets 55.9% from coal, 28.3% from natural gas, 8.2% from nuclear, 6.7% from oil, and 0.5% from hydroelectric. Alliant owns power plants in Illinois, Iowa, Minnesota, and Wisconsin.[2]

Coal Exit

In 2020 Alliant Energy set an “aspiration” to reach net-zero carbon by 2050 and eliminate all coal power plants from its fleet by 2040. Coal capacity made up 31 percent of the companies capacity in 2018.[3]

Coal-fired Power Plants

Alliant Energy had 30 coal-fired generating stations in 2005, with 4,055 MW of capacity. Here is a list of Alliant's coal power plants with capacity over 100 MW:[2][4][5]

Coal plant closures

Alliant cancels proposed Iowa plant

On March 5, 2009 Alliant subsidiary Interstate Power and Light Company announced that it was cancelling the proposed Sutherland Generating Station Unit 4. The company said the decision was based on a combination of factors, including the financial climate and concerns about the possibility of future regulation of greenhouse gas emissions.[6]

2010: Alliant to close coal boilers at six sites

According to plans filed with the Minnesota Public Service Commission on November 1, 2010, Alliant Energy plans to close coal-fired boilers at six sites in Iowa:[7]

The plan also designates two boilers at Dubuque Generating Station and another at the Sutherland Generating Station for retirement in 2015. Of this list, only one boiler (Lansing 3) is currently operational, and the replacement generation will come in significant part from running newer coal boilers at higher capacity.[7]

Proposed gas plant

As of April 2011, Alliant Energy is debating a natural gas plant for Iowa. Natural gas emerged as a possibility after the utility revised its future power-production projection downward, going from needing an additional 300 megawatts by roughly 2013 to 200 megawatts by 2025. Less demand has made the company consider natural gas, although the company has said it would not rule out a new coal plant later.[8]

Coal lobbying

Alliant is a member of American Coal Ash Association (ACAA), an umbrella lobbying group for all coal ash interests that includes major coal burners Duke Energy, Southern Company and American Electric Power as well as dozens of other companies. The group argues that the so-called "beneficial-use industry" would be eliminated if a "hazardous" designation was given for coal ash waste.[9]

ACAA set up a front group called Citizens for Recycling First, which argues that using toxic coal ash as fill in other products is safe, despite evidence to the contrary.[9]

Ties to the American Legislative Exchange Council

Alliant Energy has been a member of the American Legislative Exchange Council (ALEC). It sponsored ALEC's 1998 annual meeting.[10] Please see ALEC Corporations for more.

The company confirmed to Greenpeace in May 2014 that it had cut ties to ALEC.[11] Please see Corporations that Have Cut Ties to ALEC for more.

About ALEC
ALEC is a corporate bill mill. It is not just a lobby or a front group; it is much more powerful than that. Through ALEC, corporations hand state legislators their wishlists to benefit their bottom line. Corporations fund almost all of ALEC's operations. They pay for a seat on ALEC task forces where corporate lobbyists and special interest reps vote with elected officials to approve “model” bills.

Lawsuit by Sierra Club

In March of 2008 Alliant Energy based in Madison, Wisconsin received a notice of intent to sue from the Sierra Club. The notice claimed that the company did not file applications for air permit renewal on a timely basis and in doing so violated the Clean Air Act. In 2009, as a result of pressure from the Sierra Club and others, the federal government revoked its permit to the Columbia Energy Center. The result could mean that Alliant will be forced to install pollution reduction equipment or it could mean shutting down the facility for good.[12]
