(Madison, Wisconsin) – Alliant Energy has filed a request with the Iowa Utilities Board (IUB) to adjust Iowa customers’ electric and natural gas rates, beginning in late 2024. The company is requesting a 7.7% (approximately $10 per month) increase to the average residential electric customer’s total bill beginning in October 2024 and a second phase increase of 5.7% (approximately $7 per month) to take effect beginning in October 2025. For natural gas customers, they are requesting a 5% increase (approximately $3 per month) to the average residential gas customer’s total bill in October 2024. The proposal and has to go through a lengthy process before it goes into effect. Company officials say this should give customers time to prepare for the changes.

The IUB will review the request within 10 months and establish final rates, which could be different from the proposed rates. They will also determine if and when any changes in final rates become effective.

Alliant says customers do have the right to file written comments and objections with the IUB that include any facts that would assist the Board in reviewing the proposed rate adjustment. Customers also have the right to request a public hearing regarding the proposed new rates. Comments, objections, or hearing requests can be submitted to the Iowa Utilities Board online, by email at customer@iub.iowa.gov or by mail at Iowa Utilities Board, 1375 E. Court Avenue, Des Moines, IA 50319-0069. All comments are a matter of public record and available to the Office of Consumer Advocate, who represents the public interest in rate cases before the IUB.
