Residential prices for electricity are charged using tiered pricing. Tiered pricing means different prices are charged depending how much energy you use. The less energy a customer uses, the less energy the customer is charged at a higher prices. By staying in a lower tier, you pay less. Tiered pricing encourages customers to conserve energy and use it efficiently.
Residential Tiered Prices
Service charge per month: $15.00
Idaho Power’s rates are higher in the summer. Our service area experiences the highest demand for energy in the summer, so rates increase from June through September — due in part to higher wholesale prices Idaho Power pays for energy in the summer months. Customers may see an increase on their bills due to summer rates and increased energy use.
Summer (June-September)
| Tier 1 | Tier 2 | Tier 3 | |
|---|---|---|---|
| Kilowatt-hours (kWh) | 0–800 | 801–2,000 | Over 2,000 |
| Price (cents per kWh) | 12.1195¢ | 13.2995¢ | 14.6185¢ |
Non-Summer (October-May)
| Tier 1 | Tier 2 | Tier 3 | |
|---|---|---|---|
| Kilowatt-hours (kWh) | 0–800 | 801–2,000 | Over 2,000 |
| Price (cents per kWh) | 9.9332¢ | 10.4305¢ | 11.0052¢ |
Annual Cost Adjustments
| Cost Adjustment | Amount |

Example of Tiered Pricing
As an example, a residential customer who uses 1,050 kWh during March would be billed at the non-summer price. The breakdown of this customer’s energy charges according to the tiered price structure would be as follows:
800 kWh × 9.9332 cents (tier 1) = $79.47
250 kWh × 10.4305 cents (tier 2) = $26.08
= 1050 kWh = $105.55
If the same customer uses 2,225 kWh during the same time, the energy charge would span all three tiers:
800 kWh × 9.9332 cents (tier 1) = $79.47
1,200 kWh x 10.4305 cents (tier 2) = $125.17
225 kWh × 11.0052 cents (tier 3) = $24.76
= 2,225 kWh = $229.40
If that same customer used only 800 kWh during the same time, the energy charge would fall only into the lower-price tier 1:
800 kWh × 9.9332 cents (tier 1) = $79.47
Being energy efficient saves you money!
