Why is electricity so expensive in New Mexico?
New Mexico pays 15.06¢/kWh for residential electricity, 17.9% below the U.S. average of 18.34¢/kWh and the #14 lowest of 51 jurisdictions. At 900 kWh a month that is about $135.54, against $165.06 at the U.S. average. The rate itself is not what makes a New Mexico bill expensive; usage usually is, and the checklist in our high-bill guide separates the two.
Rates are EIA residential averages through June 2026, refreshed Sep 9, 2026. The U.S. average is the EIA U.S.-total residential price; rank and region figures compare the 51 jurisdiction averages.

What the EIA series shows for New Mexico
- Past 12 months (June 2025 → June 2026)
- The New Mexico residential rate rose 2.6% (+0.38¢/kWh), from 14.68¢ in June 2025 to 15.06¢ in June 2026.
- Past 5 years (June 2021 → June 2026)
- The rate rose 8.5% (+1.18¢/kWh), from 13.88¢ in June 2021 to 15.06¢ in June 2026.
- Past 10 years (June 2016 → June 2026)
- The rate rose 23.8% (+2.90¢/kWh), from 12.16¢ in June 2016 to 15.06¢ in June 2026.
- Highest and lowest month on record
- In this series the New Mexico rate peaked at 16.52¢/kWh in September 2025 and bottomed at 7.41¢/kWh in February 2002. The series covers January 2001 to June 2026.
- Steepest 12-month increase
- The largest single-year move in the series ended in October 2011: the rate rose 20.8% (+2.21¢/kWh), from 10.63¢ in October 2010 to 12.84¢ in October 2011. That is when the change happened; the series does not say what caused it.
- Against the rest of the country
- Over the same window the unweighted average across the 51 jurisdictions with data for this period rose 34.8%, so New Mexico's +8.5% lagged the nationwide move by 26.3 percentage points. That gap is the part of the movement this dataset cannot attribute to a nationwide trend — it does not identify what else was involved.
- Rank among jurisdictions (June 2021 → June 2026)
- Measured over that identical five-year window, New Mexico's change is the 51st largest of the 51 jurisdictions whose series covers it — rank 1 is the biggest increase, rank 51 the biggest decrease. The rank places the movement; it does not explain it.
Between January 2001 and June 2026 the rate peaked at 16.52¢/kWh in September 2025 and bottomed at 7.41¢/kWh in February 2002.

What generally moves electricity rates
A rate series shows what changed, not why. This dataset records New Mexico's residential rate and nothing about what moved it, and no reviewed New Mexico driver analysis is published yet — so this page makes no causal claim. The factors that generally move retail rates are documented separately.
- Fuel and purchased power. Natural gas, coal, and wholesale power prices pass through to retail rates, often with a lag of months.
- Generation mix. Hydro and legacy nuclear tend to hold rates down; imported fuel, oil, and constrained supply tend to push them up.
- Wires investment. Transmission and distribution upgrades, storm hardening, and wildfire mitigation are recovered through rates over years.
- Market structure. Regulated utilities set rates in rate cases; deregulated markets price supply competitively and bill delivery separately.
- Demand and weather. Load growth, peak-heavy demand, and extreme weather raise the cost of serving each kilowatt-hour.
the factors themselves are documented on electricity generation cost drivers.
