Energy costs in Boise City, ID
Energy prices are published by state, not by city, so the rates and bills below are Idaho figures and apply to Boise City the same as anywhere else in the state. The solar production is different: that is modelled for Boise City's own coordinates, and it varies a lot within a single state.
Solar at Boise City's coordinates
8,810kWh a year from 6 kW
That is 6% more than the Idaho average, which is the sort of gap that makes a state figure the wrong one to plan with. At 12.35¢ a kilowatt hour it pays back in about 10.8 years with full net metering.

Common questions
What is the electricity rate in Boise City?
12.35¢ per kilowatt hour. That is the Idaho residential average from the EIA — rates are published per state, not per city, so it applies across Boise City and the rest of Idaho alike.
What is the average electric bill in Boise City?
About $111 a month for a typical Idaho household. Again this is a state figure: EIA reports revenue and customer counts by state, so a city-level bill would be an invention.
Is solar worth it in Boise City?
A 6 kW system at Boise City's coordinates is modelled at about 8,810 kilowatt hours a year, which pays for itself in roughly 10.8 years at Idaho electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
