Alliant Energy Corporation (NYSE: LNT) is a public utility holding company that incorporated in Madison, Wisconsin in 1981. It consists of two subsidiaries:[3]
Interstate Power and Light Company (IPL) is a public utility that generates and distributes electricity, and purchases and distributes natural gas in Iowa and Minnesota.
Wisconsin Power and Light Company (WPL) provides similar services as IPL in Wisconsin.

Alliant Energy Corporation (Alliant Energy), incorporated in 1981, operates as a regulated investor-owned public utility holding company. The Company focuses to provide regulated electricity and natural gas service to approximately one million electric and approximately 412,000 natural gas customers in the Midwest through its two public utility subsidiaries. The subsidiaries of the Company include Iowa Railway and Light Corporation (IPL), Eastern Wisconsin Electric Company (WPL), Alliant Energy Resources, LLC (Resources) and Alliant Energy Corporate Services, Inc. (Corporate Services). IPL is a public utility engaged principally in the generation and distribution of electric energy and the distribution and transportation of natural gas in selective markets in Iowa and southern Minnesota. WPL is a public utility engaged principally in the generation and distribution of electric energy and the distribution and transportation of natural gas in selective markets in southern and central Wisconsin. Alliant Energy’s non-regulated investments are organized under Resources. Corporate Services provides administrative services to Alliant Energy and its subsidiaries. The Company’s utility business has three segments: electric operations, gas operations and others.
Electric Utility Operations
The electric utility operations represent the operating segment for Alliant Energy, IPL and WPL. Alliant Energy’s electric utility operations are located in the Midwest with IPL and WPL providing electric service in Iowa, southern and central Wisconsin and southern Minnesota. IPL and WPL provide electric utility service to retail customers in several industries, with concentrations in the food manufacturing, chemical (including ethanol) and paper industries. Wholesale customers, who primarily consist of municipalities and rural electric cooperatives, are billed under wholesale service agreements. IPL and WPL own a portfolio of electric generating facilities located in Iowa, Wisconsin and Minnesota with a fuel mix, including coal, natural gas and renewable resources. Coal is the primary fuel source for Alliant Energy’s, IPL’s and WPL’s internally generated electric supply and generally represents approximately 50% of their total sources of electric energy. Alliant Energy owns several natural gas-fired generating facilities including IPL’s 565 megawatt Emery Generating Station, WPL’s 300 megawatt Neenah Energy Facility and Resources’ 300 megawatt Sheboygan Falls Energy Facility.
Gas Utility Operations
Alliant Energy’s gas utility operations are located in the Midwest with IPL and WPL providing gas service in Iowa, southern and central Wisconsin and southern Minnesota. In addition to sales of natural gas to retail customers, 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. IPL and WPL maintain purchase agreements with over 40 suppliers of natural gas from various gas producing regions of the United States and Canada. In providing gas commodity service to retail customers, Corporate Services administers a portfolio of transportation and storage contracts on behalf of IPL and WPL.
Steam Utility Operations
IPL has provided steam service to approximately 200 customers in Cedar Rapids, Iowa, who used high-pressure steam for production purposes or low-pressure steam for hot water and heat. In December 2009, IPL ceased low-pressure steam operations in downtown Cedar Rapids.

As IPC sold its properties that were isolated from the main system, it picked up others that were adjacent to its system and more easily interconnected: the Eastern Iowa Power system, and the Iowa / Minnesota properties of the Central States Power and Light Corporation.
The Wisconsin operations were sold to Wisconsin Power and Light (ironically, now the eastern half of Alliant's operations).
The other part of IPL — IES Utilities — incorporated in Iowa in 1925 as the Iowa Railway and Light Corporation. IES expanded across that part of Iowa south of IPC's territory, eventually acquiring the Iowa operations of the Union Electric Company of St. Louis, MO.
IES and IPC merged in the mid-1990s to form IPL. Today, IPL provides electricity and gas to communities in Iowa and southern Minnesota; while WPL serves the state of Wisconsin.[4] In late 2007, Alliant Energy received final approval to sell their utility services in Illinois to Jo-Carroll Energy.
In the 1970s IES constructed the Duane Arnold Energy Center, a 615 MW nuclear plant in Palo, Iowa. In 2006, Alliant closed a deal with FPL Energy to sell their stake in the plant.
Alliant Energy also provides several non-regulated services, including ground transportation and energy engineering (such as wind and geothermal energy).
