ALLIANT ENERGY CORP
Alliant Energy Corp, trading as LNT, is rooted in Electric & Other Services Combined, delivering regulated electricity and natural gas distribution alongside transmission investments for residential, commercial and municipal customers in Midwestern markets governed by SIC 4911 legacy standards. The firm’s core offerings span power generation from utility-scale coal, natural gas and renewable sources, grid modernization, and customer-centric efficiency programs, while its gas operations supply heating and industrial fuel needs with bundled reliability services. Its target customers include households, small businesses, industrial facilities and local governments reliant on consistent delivery, billing platforms, and energy advisory support. Regulatory oversight from state public utility commissions and the Federal Energy Regulatory Commission enforces cost recovery, rate structures and environmental compliance, creating material risks such as demand fluctuations, fuel price shocks, wildfire and storm exposure, plus evolving decarbonization mandates that pressure capital plans and peaking capacity additions.
