Average Electric Bill in Idaho (2026)

Idaho Electricity Cost Comparison

Electricity Rates in Idaho Are Rising

Electricity rates across the United States have been increasing at an average of 2.5% per year, and Idaho is no exception. At the current rate of 11.82¢/kWh, your average monthly bill of $105 could grow to $119/month within 5 years and $134/month within 10 years — that's an increase of $29/month without changing your usage habits at all.

Solar energy effectively locks in your electricity cost at today's prices. Once your system is installed and paid off, the electricity it produces is free for the remaining lifespan of the panels (25-30+ years). This hedge against rising rates is one of the most compelling financial arguments for going solar, especially in states like Idaho where rates are competitive but still rising.

Idaho homeowners with solar typically reduce their electricity bills by 70-100%, saving approximately $1071 per year. Over the 25-year lifespan of a solar system, total savings in Idaho typically range from $$21,420 to $$32,130 when factoring in rate increases.

How Solar Reduces Your Idaho Electric Bill

When you install solar panels, they generate electricity during daylight hours that directly powers your home. Any excess electricity is typically sent back to the grid through net metering, earning you credits on your utility bill. Idaho offers reduced-rate net metering, meaning credits are earned at a rate below retail. Your savings are still significant but slightly lower than full retail states.

With 4.7 peak sun hours per day in Idaho, a properly sized 8kW solar system produces approximately 13,724 kWh per year — enough to offset most or all of an average Idaho household's electricity consumption.

The best way to determine exactly how much solar can save on your specific Idaho electric bill is to get a personalized quote from a licensed installer. They'll analyze your actual usage data, roof conditions, and local utility policies to provide an accurate savings projection.
