DES MOINES, Iowa — The Iowa Utilities Commission has approved Alliant Energy’s request for a $185 million per year electric rate increase and is requiring transparency for future investments.
Tuesday, the Iowa Utilities Commission (IUC) ruled on an application Alliant filed late in October 2023. The application sought an increase in electric and natural gas rates, requesting a revenue increase of around $284 million for electric and $14 million for natural gas. In June 2024, a settlement was filed requesting the electric revenue increase be lowered to $185 million and natural gas revenue be reduced to $10 million.
The IUC ruling resolves the Alliant case and other similar contested issues. This increase will lead to the average customer’s monthly electric bill rising from $13 to $15.50. The order implements a rate increase cap of 15% for each customer class and approves a conditional electric rate base moratorium through October 2029.
