About Us

Allamakee-Clayton Electric Cooperative was organized in 1938 because investor-owned utilities bypassed rural Iowa due to its sparse population.

ACEC provides electric power to more than 9,900 customers on over 2,500 miles of line in portions of eight counties: Allamakee, Clayton, Fayette, Winneshiek, Chickasaw, Bremer, Delaware and Dubuque.

Located in the extreme northeast corner of Iowa, the state of Minnesota borders our service area on the north and the Mississippi River runs along our eastern border. Our headquarters is located at Postville which is geographically near the center of our service area. We maintain 24-hour, around-the-clock service. Our customer base is 95% farm and rural residential.

ACEC's wholesale power supplier is Dairyland Power Cooperative, based in La Crosse, Wis. Dairyland provides the wholesale electrical requirements for 25 electric distribution cooperatives and 17 municipal utilities.
