Umpqua Indian Utility Cooperative

The Umpqua Indian Utility Cooperative (UIUC) serves wholesale electrical loads of the Cow Creek Band of Umpqua Tribe of Indians at their casino and truck stop developments near Canyonville, Oregon. About 2.5 megawatts of power purchased from the Bonneville Power Administration is distributed by UIUC, which is the first tribal utility to acquire existing utility infrastructure and begin operation with a different power supplier.
