The Oregon Public Utility Commission (PUC) is the chief electric, gas and telephone utility regulatory agency of the government of the U.S. state of Oregon. It sets rates and establishes rules of operation for the state's investor-owned utility companies. With respect to publicly owned utility districts and cooperatives, its authority is limited to safety regulations. A second major change occurred in 1995. State legislative action transferred the responsibility for regulating motor transportation and rail safety to the Oregon Department of Transportation.
