About
Alliant Energy Corporation is a Madison, Wisconsin-based regulated electric and natural gas utility — publicly traded on NASDAQ (NASDAQ: LNT) as an S&P 500 Utilities component — serving approximately 1 million electric customers and 430,000 natural gas customers in Iowa and Wisconsin through two regulated subsidiaries: Interstate Power and Light Company (IPL, Iowa) and Wisconsin Power and Light Company (WPL, Wisconsin), through approximately 3,000 employees. In fiscal year 2024, Alliant Energy reported ongoing earnings per share of $3.04 (up from $2.82 in 2023), meeting analyst expectations, with 2025 guidance affirmed at $3.15-$3.25 per share. CEO Lisa Barton assumed leadership in January 2024, initiating the next phase of Alliant's clean energy transition strategy. The company completed 1,500 megawatts of solar generation investments in 2024, supplementing its existing 1,800 MW wind portfolio to accelerate the retirement of coal-fired generation — with plans to cease coal operations at Wisconsin facilities before 2030 and eliminate coal from the entire fleet by 2040, targeting net-zero carbon emissions by 2050. Alliant's foundation traces to 1917 through predecessor utility companies serving the Upper Midwest. The US Department of Energy's Loan Programs Office issued a conditional commitment to Alliant for loan support to improve grid resilience in Iowa and Wisconsin, enabling investment in transmission and distribution modernization that supports renewable energy integration and grid reliability under increasing extreme weather events.

About

Duke Energy is one of the largest regulated utilities in the United States with approximately $29 billion in annual revenue, managing a generation fleet spanning nuclear, natural gas, coal (transitioning to retirement), solar, and wind across a 100,000-square-mile service territory. CEO Lynn Good, who has led Duke Energy since 2013, filed the company's 2025 Carolinas Resource Plan responding to unprecedented load growth — North Carolina attracted $19 billion in announced business investments and 25,000+ new jobs in 2025 alone, driven by semiconductor manufacturing, data center construction, and electric vehicle manufacturing — resulting in electricity demand growth projections 8x greater than the prior 15-year trend. The plan calls for 4,000 megawatts of solar capacity by 2034 and battery storage expansion to 5,600 megawatts by 2034 (+2,900 MW from current levels).
