What the EIA series shows for New Hampshire
- Past 12 months (July 2025 → July 2026)
- The New Hampshire residential rate rose 16.7% (+3.81¢/kWh), from 22.79¢ in July 2025 to 26.60¢ in July 2026.
- Past 5 years (July 2021 → July 2026)
- The rate rose 39.6% (+7.55¢/kWh), from 19.05¢ in July 2021 to 26.60¢ in July 2026.

- The rate rose 48.2% (+8.65¢/kWh), from 17.95¢ in July 2016 to 26.60¢ in July 2026.
- Highest and lowest month on record
- In this series the New Hampshire rate peaked at 32.26¢/kWh in September 2022 and bottomed at 11.26¢/kWh in September 2001. The series covers January 2001 to July 2026.
- Steepest 12-month increase
- The largest single-year move in the series ended in September 2022: the rate rose 56.1% (+11.60¢/kWh), from 20.66¢ in September 2021 to 32.26¢ in September 2022. 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 33.7%, so New Hampshire's +39.6% outpaced the nationwide move by 5.9 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 (July 2021 → July 2026)
- Measured over that identical five-year window, New Hampshire's change is the 14th 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 July 2026 the rate peaked at 32.26¢/kWh in September 2022 and bottomed at 11.26¢/kWh in September 2001.

What generally moves electricity rates
A rate series shows what changed, not why. This dataset records New Hampshire's residential rate and nothing about what moved it, and no reviewed New Hampshire 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.
