Iowa residential rate options

With the Summer Saver rate option, you can reduce the amount you pay for electricity during the summer months by limiting usage at key times.

We’ll bill electricity you use from 2-7 p.m. on weekdays in June, July and August at a premium on-peak rate, excluding Independence Day.

We’ll charge a lower off-peak rate at all other times on those days, as well as on weekends and in the months of September through May.

On your bill, we’ll list this rate as 407 - Electric Residential TOD.

The Night Owl rate option is best for customers who can use most of their energy between midnight and 8 a.m.

We charge the lowest rate year-round from midnight to 8 a.m. We charge the highest rate weekdays June 1-Aug. 31 from 2-7 p.m. We charge a medium rate all other times.

With this rate, you will see these charges on your bill each month:

1. The demand charge is based on your peak demand during on-peak hours. In winter the rate is $12.63 per kilowatt of on-peak demand. In summer it’s $17.77 per kilowatt of on-peak demand.
   
   Peak demand is the spike in your monthly billing cycle when you use the most energy. If you manage your energy demand throughout the day, you can lower the peaks in your usage. A lower peak means a lower demand charge.
2. The energy charge is based on the amount of energy you use.
3. The service charge is a daily charge based on the number of days in your billing cycle.

On your bill, we’ll list this rate as 507 - Electric Residential TOD.
