Iowa rates and regulatory information

Tariff and regulatory documents

A tariff is a group of schedules filed with our regulatory commissions. Tariffs contain basic rates, supplemental rates or riders, and general terms and conditions for providing utility service.

The rates don’t apply to a residence used for commercial, professional or business activities. But if the domestic use can be separately metered from the business activities, then these rates would apply to the domestic part.

We consider a single-family dwelling one in which four sleeping rooms or more are rented or are available for rent as non-domestic, and the applicable general service rate applies.
