Solar value under Idaho Power's export credit
Newer Idaho Power solar customers are on net billing. Older systems grandfathered under the previous net metering rules keep their original terms. Under the rates the Idaho Public Utilities Commission approved in fall 2025, the rate is about 15.68 cents per kWh during summer on-peak hours (June through September, 3 to 11 p.m., Monday through Saturday), 3.39 cents during summer off-peak hours and 2.90 cents during all other months.
The commission suspended annual updates, and the next update is not expected until 2028. For Boise homeowners, the practical goal is to use more of the solar energy your system produces. Right-sizing around self-consumption and adding a battery can create more value than simply oversizing the array.
