Iowa's Electric Profile (as of December 31, 2010)

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.
