The Iowa Utilities Board (IUB) issued an order today establishing a procedural schedule in the application to increase retail natural gas and electric rates filed on October 12, 2023, by Interstate Power & Light Company (IPL), a subsidiary of Alliant Energy (Alliant). IPL’s request is identified as Docket No. RPU-2023-0002. 

The procedural schedule sets a June 18, 2024 deadline for parties to reach a proposed settlement to any contested issues. A public evidentiary hearing for the presentation of evidence and the cross-examination of witnesses is scheduled for July 9-12, 2024, in the IUB Hearing Room.  

IPL’s application seeks an increase in natural gas service revenue of approximately $14 million, or 5 percent above its existing gas revenue requirement, and an increase in electric service revenue of $284 million, or approximately 16 percent above its existing electric revenue requirement. IPL’s proposal would implement an increase in customers’ rates in two phases, in October 2024 and October 2025

Alliant-IPL serves approximately 500,000 electric and 225,000 natural gas retail customers across Iowa.
