Iowa's Electric Profile (as of December 31, 2012)

The Iowa Utilities Board (IUB) has regulatory authority over Investor-owned utility (IOU) rates and other service issues.   IUB authority is mostly limited to service, safety, and engineering issues for the Municipal Electric (Muni) and Rural Electric Cooperative (REC) utilities in Iowa.  The IUB has very limited authority for non-utility generators.

Amana Society Service Company
is an investor-owned utility but it is not rate regulated due to the number of customers it serves. For this reason, it files its annual report information on Form EC-1 rather than Form IE-1. The information required in the Form IE-1 is more applicable to a rate-regulated utility.
