About Alliant Energy Corporation

The spark of Alliant Energy's business is keeping the lights on and stoves lit for its upper Midwest customers. Alliant is the parent of two regulated utility companies, Interstate Power and Light (IPL) and Wisconsin Power and Light (WPL), which together serve approximately 970,000 electricity customers and approximately 420,000 natural gas customers in Iowa and Wisconsin. In addition to providing retail energy, the utilities sell wholesale electricity in Iowa, Illinois, and Minnesota.


Alliant reports financial information for three segments: Electric Operations, Gas Operations, and Other. Organizationally, the company's operations are primarily managed by its two regulated utility companies, Interstate Power and Light (IPL) and Wisconsin Power and Light (WPL).

The Electric Operations segment, accounting for about 85% of revenue, represent the largest operating segment for Alliant Energy, IPL and WPL. Alliant Energy's electric utility operations are located in the Midwest with IPL providing retail electric service in Iowa and WPL providing retail and wholesale electric service in Wisconsin. IPL also sells electricity to wholesale customers in Minnesota, Illinois and Iowa.

The Gas Operations unit, accounting for 15% of sales, located in the Midwest with IPL providing gas service in Iowa and WPL providing gas service in Wisconsin. In addition, IPL and WPL provide transportation service to commercial and industrial customers by moving customer-owned gas through Alliant Energy's distribution systems to the customers' meters.

Other operations include IPL's Prairie Creek facility is the primary source of steam for IPL's two high-pressure steam customers in Iowa. These customers are each under contract through 2025 for taking minimum quantities of annual steam usage, with certain conditions.

Geographic Reach

Madison, Wisconsin-based Alliant Energy provides retail electricity and gas in a 54,300 sq. mi. territory covering most of Iowa and southern Wisconsin. It generates electricity in both states and purchases natural gas from other parts of the US and from Canada. It sells some electricity to wholesale customers in Iowa and Wisconsin, as well as in Minnesota and Illinois.

Sales and Marketing

Through its regulated utility companies, Alliant Energy serves approximately 970,000 electric and approximately 420,000 natural gas retail purchasers, including residential, industrial, and commercial customers. It also serves wholesale customers such as municipalities and rural electric cooperatives.

Financial Performance

Despite sluggish energy usage growth in the US utility industry due to conservation efforts, Alliant has maintained steady revenue in the $3.2 to $3.7 billion range over the past five years.

In 2019, the company's revenue increased by $113.2 million to $3.6 billion from $3.5 billion in 2018. Alliant Energy's most significant source of cash is from electric and gas sales to IPL's and WPL's customers. Cash from these sales reimburses IPL and WPL for prudently-incurred expenses to provide service to their utility customers and generally provides IPL and WPL a return of and a return on the assets used to provide such services.

Net income rose 9% in 2019 to $567.4 million on higher revenue, despite an increase in operating expenses (including electric production and purchasing, transmission, and gas purchasing costs). Lower income taxes (resulting from the 2017 Tax Act) also boosted profits.

Net cash in 2019 was $17.7 million, 8% less from the prior year. Cash from operations was $660.4 million, cash used for investing activities was $1.3 billion, and cash from financing activities was $619.1 million.


Alliant Energy's strategy focuses on affordable energy solutions that support retention and growth of its existing customers and attract new customers to its service territories.

Alliant Energy's strategy includes actions to retain current customers and attract new customers into IPL's and WPL's service territories in an effort to keep energy rates low for all of their customers. The company strategy also includes constructing renewable generating facilities, large-scale additions and upgrades to our electric and gas distribution systems, constructing a natural gas-fired generating facility, and making other large-scale improvements to generating facilities.

Company Background

Alliant Energy was created in 1998 by the three-way merger of WPL Holdings (Wisconsin Power & Light), IES Industries, and Interstate Power. Alliant Energy combined the utility operations of IES Industries and Interstate Power to form Interstate Power and Light (IPL) in 2002.

Prior to 2015 the company's Minnesota operations included electric distribution assets that served more than 40,000 retail customers. It exited the retail market in that year but continued to sell wholesale electricity into the Minnesota market.
