Alliant Energy

Alliant Energy Corporation (NASDAQ: LNT) is a regulated utility holding company headquartered in Madison, Wisconsin, providing essential energy services to communities across the Midwest. Through its two principal subsidiaries—Interstate Power and Light Company (IPL) serving Iowa and Wisconsin Power and Light Company (WPL) serving Wisconsin—the company delivers electricity to approximately 1 million customers and natural gas to 430,000 customers across Iowa and Wisconsin. With a legacy dating back to 1917, Alliant Energy has evolved into a modern utility focused on clean energy transformation, having completed 1,500 megawatts of solar generation investments in 2024 to complement its existing 1,800 megawatts of wind resources.

The company operates as a vital infrastructure provider in the region, maintaining a diverse generation portfolio that includes renewable energy, natural gas, and coal-fired facilities, though it is actively transitioning away from coal with plans to cease burning coal at its Wisconsin facility before 2030. Alliant Energy's 2024 financial performance demonstrated resilience with ongoing earnings per share of $3.04, meeting analyst expectations, and the company has reaffirmed 2025 guidance of $3.15-$3.25 per share. The utility serves a balanced mix of customers, with approximately 85% residential accounts, 15% commercial accounts, and a small portion of industrial properties, providing reliable and affordable energy while advancing sustainability goals.

In recent years, Alliant Energy has positioned itself at the forefront of the clean energy transition, setting an aspiration to reach net-zero carbon emissions by 2050 and eliminate all coal power plants from its fleet by 2040. The company retired a major coal-fired facility in Iowa in 2023 and continues to invest heavily in renewable energy infrastructure and grid modernization. With approximately 3,000 employees dedicated to delivering exceptional service, Alliant Energy has received conditional commitment from the U.S. Department of Energy's Loan Programs Office to improve grid resilience in Iowa and Wisconsin. The company's leadership transition in January 2024, with Lisa Barton assuming the role of CEO, marks a new chapter focused on strengthening the clean energy element of the company's balanced generation portfolio while maintaining reliability and affordability for customers throughout the region.
