High electricity rates plus a live per-kWh battery incentive and genuine storm-outage risk make batteries more compelling here than in most states, though the federal purchase credit is gone for 2026 cash buyers.

Average residential rate
27 cents per kWh
Net metering
Net metering available; smaller systems get near-retail credit, larger residential systems use a reduced blended rate set by the state PUC.
State battery incentive
NH Clean Energy Fund Home Battery (Eversource): $230 per kWh, up to $3,000, paid upfront with no annual performance payments and a three-year demand-response participation requirement. Separate from Eversource's ConnectedSolutions program, which pays $225 per average kW on performance instead. Funding is limited; confirm availability for your program year.

What drives battery value here
Rural, tree-heavy grid with ice and wind storms that can cause multi-day outages. Backup during winter storm outages is a real driver here; confirm the current battery incentive with your utility before assuming eligibility.
The federal picture in 2026
The federal residential purchase credit (Section 25D) expired on December 31, 2025, so a 2026 cash buyer gets nothing federal. The only surviving federal pathway is Section 48E, which a company claims on a lease or PPA. State and utility programs, where they exist, now do the heavy lifting.
