Where New Hampshire rates are today
With an average price just under 28¢ per kWh, New Hampshire electricity rates are well above the national average but slightly lower than other New England states. Small population and limited local generation mean that consumers pay high supply and distribution costs.
Why New Hampshire rates have been the way they are
- ISO‑NE capacity and transmission costs: New Hampshire is part of ISO‑New England, so wholesale prices reflect regional capacity auctions and transmission upgrades.
- Limited in‑state generation: The state has little large‑scale generation and depends on power imports, making it sensitive to regional fuel prices.
- Natural gas exposure: Like other New England states, New Hampshire’s electricity prices track natural gas markets closely.
- Policy costs: Renewable energy incentives and efficiency programs contribute to supply charges.
Where New Hampshire rates are going in the next 3 months
Heading into the 2025‑26 winter, New Hampshire customers can expect slight upward movement—around 1‑3%—in supply rates. Higher regional demand and capacity costs will pressure prices, although a mild winter or softening natural gas prices could moderate increases.
Key takeaway for businesses
New Hampshire remains a high‑cost electricity market. Shop among competitive suppliers to find fixed‑rate offers and consider locking in rates before winter to avoid potential spikes.
