WISCONSIN POWER & LIGHT CO

Wisconsin Power & Light Co. is a long-established regulated electric utility serving communities across southern Wisconsin and parts of northern Illinois, delivering power that stems from its mix of coal, natural gas, nuclear, and renewable generation assets before flowing through a widespread transmission and distribution grid; it markets reliable electricity and energy services to residential neighborhoods, commercial enterprises, and industrial customers while increasingly focusing on modern grid investments and customer-facing programs that smooth demand and support sustainability goals. Operating within SIC 4911 and subject to intensive oversight from state public service commissions and the Federal Energy Regulatory Commission, the company must manage the material risks of fuel-price volatility, capital-intensive infrastructure upgrades, extreme weather, and evolving environmental mandates that can reshape costs and timelines, all while balancing the expectations of regional stakeholders and communities.
