CITIZEN SCIENCE OPPORTUNITY: Help CEDI Calculate the Actual Impact of Rate Increases

Iowa’s ALLIANT ENERGY CUSTOMERS have a valuable opportunity RIGHT NOW to calculate the impact of Alliant’s 2024 electric rate increases. CEDI invites ratepayers to DOWNLOAD their electric billing data and submit it confidentially to CEDI for independent analysis.

In exchange, CEDI will send an overview (anonymized) of all rate impacts reported, which we will also submit to the Iowa Utilities Commission.

WHY NOW? Alliant Energy has to provide data to the Iowa Utilities Commission one year from the date the rate increase went into effect (October 1, 2024) to demonstrate that ratepayer bill increases are not higher than the Commission has authorized.

PLEASE USE THIS FORM to share your electric usage data. ALL DATA is confidential and will be anonymized in CEDI’s independent analysis.

It’s critical that we download and examine this data BEFORE DEC 1, 2025, allowing a clear comparison of your costs BEFORE Alliant’s most recent rate increase, compared with your costs AFTER the increase.
