Deregulated Energy in New Hampshire: Compare Electricity, Internet & Home Services
Deregulated energy New Hampshire residents can access has been available since 1996, making it one of the earliest adopters of retail energy competition in the country. As a smaller New England state with electricity rates consistently among the highest in the region, deregulated energy New Hampshire shopping gives residents a meaningful opportunity to reduce their supply costs below the utility’s Default Energy Service (DES) rate. The New Hampshire Public Utilities Commission (NHPUC) oversees all competitive electricity suppliers operating in the state.
Deregulated Energy New Hampshire: Utility Territories and Market Structure
Eversource Energy (NH): Southern and Central New Hampshire
Eversource Energy is the largest utility in New Hampshire, serving Manchester, Nashua, Concord, Keene, Portsmouth, and most of southern and central New Hampshire. Eversource NH sets a quarterly Default Energy Service (DES) rate that is your baseline for evaluating competitive supplier offers. Any licensed competitive supplier offering below the current DES rate is saving you money on the supply portion of your bill.
Unitil: Seacoast and Some Central NH Areas
Unitil serves portions of the New Hampshire Seacoast region and some central New Hampshire communities. Unitil customers can access licensed competitive electricity suppliers in their territory. The selection may be smaller than in Eversource territory, but national suppliers like Constellation typically serve both territories.
New Hampshire Natural Gas: Limited Availability
Natural gas availability is more limited in New Hampshire than in most other deregulated states. Many New Hampshire homes use heating oil or propane rather than natural gas. For households with natural gas access (primarily through National Grid or Liberty Utilities gas service), competitive supplier options may be available — check with your gas utility for current AGS availability in your area.
