DOE finalizes $5.1 billion loan to Alliant Energy for new gas plants and storage in Iowa and Wisconsin

The U.S. Department of Energy closed a $5.1 billion loan package for Alliant Energy to build natural‑gas‑fired power plants, add energy‑storage systems and upgrade existing facilities in Iowa and Wisconsin. The financing will create several hundred construction jobs and deliver more than 2.6 GW of new or upgraded capacity, enough electricity for roughly 1.8 million homes. The loan expands an earlier conditional $3 billion proposal made in January 2025 under the previous administration. DOE Office of Energy Dominance Financing director Gregory Beard said the project will strengthen energy security and may lower electricity costs over time.

The loan provides Alliant Energy with substantial low‑cost capital to expand generation and storage, which could improve its long‑term revenue outlook. The financing also signals broader DOE support for natural‑gas projects, potentially influencing market sentiment toward utility stocks.
