Its electric segment owns and operates a diverse portfolio of generation assets, including coal, natural gas, wind and solar facilities, while the gas segment delivers clean-burning natural gas through an extensive distribution network.
In addition to traditional generation, Alliant Energy has actively pursued renewable energy and energy efficiency programs.

Tracing its roots to early 20th-century regional utilities, Alliant Energy was formally organized under its current name in 2000 following the consolidation of Wisconsin Power and Light Company and Interstate Power and Light Company.
