State average = 22.97¢/kWh, volume-weighted across these utilities (2024). Your distribution utility is fixed by address; these gaps measure what households in different territories actually paid. A further 19 competitive suppliers / solar lessors report energy-only or behind-the-meter sales in New Hampshire; their prices cover only part of the bill and are not comparable to the all-in figures above.

How to switch suppliers in New Hampshire (3 steps)
- Find the price to compare (default supply rate) on your utility bill — you only save when an offer beats it for the same period.
- Compare licensed supplier offers on the state's official shopping site: puc.nh.gov. Check term, early-exit fees, and whether the rate is fixed or variable.
- Sign up with the supplier — they handle the switch. Your utility still delivers the power, owns the wires, and responds to outages; only the supply line of the bill changes.
