Idaho Agricultural Irrigation Rates

  • Low rates are a cornerstone of energy affordability.
  • Rates are designed to promote energy efficiency and conservation.
  • Collecting a portion of costs through a demand charge encourages efficient use of energy infrastructure and reduces cross subsidies among irrigation customers.

Why does Idaho Power have a demand (kW) charge?

The demand charge collects a portion of the fixed cost associated with the size of the connected load and encourages the smallest size to do the job. To learn more about how to minimize the impact of the demand charge, please visit Irrigation Efficiency Rewards or contact your Idaho Power Ag Rep. To learn more about the terms used on your bill, view the Bill Terminology.  

For example, if one month a customer has a Billing Demand of 10 kW and energy usage of 4,000 kWh, their bill would include: 

In-Season
Service Charge: $30
Billing Demand of 10 kW x $14.07 = $140.7
Energy Usage of 4,000 kWh x $00.057265 = $229.06

Out-of-Season
Service Charge: $6
Billing Demand: NA
Energy Usage of 4,000 kWh x $00.067288 = $269.15

Schedule 24 Monthly Rates – Secondary Service
  In-Season
