How Idaho Utility Rates Compare to the National Average

Idaho consistently offers some of the most affordable utility rates in the United States, largely due to its significant reliance on hydroelectric power. As of late 2026, residents typically enjoy utility costs well below the national average, making the state an attractive option for those considering relocation.

Updated with grounded research as of 2026-10-12.

The short answer

Idaho’s utility rates are significantly lower than the national average, with residents typically paying 22% to 35% less for electricity. This affordability is primarily driven by the state's robust hydroelectric infrastructure, which provides a consistent and low-cost energy source for the region.

Key facts

Residential Electricity Rate
Approximately 14.37¢/kWh (September 2026), significantly below the national average.
Overall Utility Cost Index
Idaho's utility costs are approximately 25% lower than the national average.
Primary Energy Source
Hydroelectric power accounts for roughly 45% of total electricity generation in Idaho.

The Impact of Hydroelectric Power

A major factor contributing to Idaho's competitive utility market is the state's reliance on renewable energy. A substantial portion of the power grid, roughly 45%, is supported by hydroelectric projects, most notably those along the Snake River system. This reliance on a stable, domestic energy source helps insulate Idaho residents from some of the price volatility seen in other regions of the country that depend more heavily on fluctuating fossil fuel markets.

What Residents Can Expect

For those relocating to Idaho, utility expenses are often a positive surprise in their monthly budget. While national averages for electricity can fluctuate, Idaho has maintained a position well below these benchmarks for years. It is important to note that while the state-wide average is favorable, your actual costs will depend on your specific utility provider—such as Idaho Power or Avista—and your individual household consumption habits.

Variables Influencing Your Bill

While Idaho maintains low rates, your bill is still subject to change based on several key factors:

Seasonal consumption: Heating and cooling demands significantly impact monthly usage.

Regulatory adjustments: Rates are influenced by the Idaho Public Utilities Commission, which oversees utility pricing and service standards.

Utility provider differences: Different regions of the state are served by various utility companies, each with its own rate structures.
