UI Rates and Riders

Understanding Rates

Your UI bill is broken down into two major components, Delivery and Generation.

  • Delivery -
    • The Delivery portion covers the cost to deliver electricity across our equipment. UI offers a variety of Delivery rates to accommodate various customer types and needs.
    • The Delivery portion of your bill includes several components, including Basic Service, Transmission, Distribution, Combined Public Benefits, Competitive Transition Assessment and Non-Bypassible FMCC line items. These pay for the equipment that delivers electricity to your home, social policy costs, and services and programs that benefit all UI customers. This portion of your bill is unchanged if you select an alternate supplier for generation service. Read more at Billing Glossary.
  • Generation -
    • The total rate you pay also includes a separate charge for Generation, which can be purchased from UI or alternate suppliers in a competitive market. Read more at Choose a Supplier.

Residential Rates RT & R

UI offers two rates for residential customers: Rate RT and Rate R.

  • Rate RT is our time-of-day rate for residential customers. From noon until 8 p.m. weekdays (the peak period), the electricity you use costs more than electricity used at other times.
  • Rate R provides a constant charge for the electricity you use regardless of when you use it. Day, night, weekend or weekday, it is the same price. There is a twice-yearly price adjustment from the winter to the summer peak period and back.
