Rate review impact on your bill (Iowa)

The average monthly bill for a typical residential customer is estimated to increase 6% beginning in October 2024.

Rate steps

Previously, bills included three different steps of rates that decreased as you used more energy. Now, bills include only one rate that only changes during the summer and winter periods, making it easier to follow how your energy use can impact your bill.

Summer / winter period

Following traditional calendar months, summer rates are now in effect from June 1 to August 31 and winter rates are in effect from September 1 to May 31. This change shortens the summer period by one month to benefit customers as rates during the summer period are higher due to the overall demands on the energy grid being greater during warmer weather. The new summer rate is $0.13398 per kWh. The new winter rate is $0.09992 per kWh.

Bill credit

You will receive a credit on your monthly bill for the next 12 months. This credit is based on kWh and will vary each month. This helps to offset some of the increase and will appear as a “Tax Benefit Rider” on your bill.

Transition to new rates

As new rates go into effect, your first new bill was calculated based on a combination of old rates and new rates. All future bills will be calculated using the new rates only.

Monthly service charge

Residential and Optional Demand customers will see an increase in the “Monthly Customer Charge” to approximately $15.50 per month.

Three-phase charge

Residential and Optional Demand customers who receive three-phase service will now see a new line item beginning on their next bill. This “Monthly Service Charge” is $45. This charge may have been incorporated into the old bills and has been broken out to provide transparency for customers. This charge reflects costs associated with additional infrastructure to provide three-phase service to customers.

Demand calculations

You are billed according to energy demand in kilowatts (kW) used during on-peak hours and off-peak hours. On-peak hours occur from 7 a.m. to 8 p.m., Monday-Friday, excluding holidays. The calculation to determine your billing demand has been simplified. Previously, billing demand was determined by the sum of the higher hourly demand during the on-peak period plus 50% of the amount of which the highest hourly demand during off-peak hours exceeded the highest on-peak demand.

Now, billing demand will be determined by the highest hourly demand during on-peak hours. Keeping your operations steady and maintaining a consistent demand helps to manage your bill.

The average monthly bill for a typical standby electric customer is estimated to increase 5.6% beginning in October 2024.

Time of Day energy rates

All electricity used during off-peak hours is billed at a discount. On-peak energy hours are from 2 -7 p.m., Monday-Friday during the summer period. Off-peak energy hours are all other times, plus Independence Day. The new energy charge is $0. 01959 per kWh during on-peak hours and $0.00896 per kwh during off-peak hours.

Demand charge/calculation

• Charge: You are billed reservation and standby demand in kilowatt (kW). Customers served at non-transmission voltage levels (under 69,000 volts) are billed distribution primary or secondary reservation and standby demand in kW. For customers served at non-transmission voltage levels, bills include one distribution reservation and standby daily demands.

• Calculation: The calculation to determine your reservation distribution demand has changed. Previously, reservation distribution demand was determined by the contracted standby demand. Now, the distribution reservation demand is determined by the observed annual peak standby demand for the previous calendar year. As-used demand is calculated in two categories: generation and distribution. Generation as-used demand is determined by the highest 15 minute on-peak standby demand during the billing period. Distribution daily as-used demand is determined by the sum of each daily maximum on-peak standby demand. Distribution reservation and daily as-used demands apply to customers served at non-transmission voltage, which is under 69,000 volts. During periods where standby power is required for operations, keeping your operations steady and maintaining a consistent demand during on-peak hours helps to manage your bill.

Bill credit

You will receive a credit on your monthly bill for the next 12 months. This credit is based on kWh and will vary each month. This helps to offset some of the increase and will appear as a “Tax Benefit Rider” on your bill.

Transition to new rates

As new rates go into effect, your first new bill was calculated based on a combination of old rates and new rates. All future bills will be calculated using the new rates only.

Monthly Service Charge

You will now see a “Monthly Service Charge” of $183.38 on your bill. This charge is simplified for all standby customers.
