New Hampshire uses utility net energy metering rather than a single statewide cents-per-kWh export price. For small systems, the current alternative tariff credits exported energy at 100% of default energy service, 100% of transmission, and 25% of distribution, while non-bypassable charges are not credited; surplus monetary credits carry forward and may be cashed out annually after the March billing cycle when the balance exceeds $100. Eligible systems are generally limited to 1,000 kW, with utility-specific capacity allocations and first-come, first-served queues.

Program details

Compensation mechanismUtility net energy metering with monthly measurement and monetary bill credits under the alternative tariff for post-August 2017 projects; small-system exports receive credit for default energy service, transmission, and 25% of distribution, while certain non-bypassable charges receive no credit.
Export rateThere is no single statewide dollar-per-kWh rate: for small customer-generators, the alternative tariff credits 100% of Default Energy Service, 100% of Transmission, and 25% of Distribution; the dollar value changes with each utility's rates. Large systems receive credit for Default Energy Service only.
Rate effectiveThe alternative net-metering tariff applies beginning September 1, 2017; the reviewed Liberty tariff page is effective May 1, 2025.
Credit rolloverYes. Small and large customer-generators receive monetary credits over subsequent billing periods and do not accumulate surplus kWh after each billing period.
Credit expirationCredits do not have a stated annual expiration in the reviewed tariff; they continue over subsequent billing periods, with cash payment available after the March 31 balance date when the monetary credit exceeds $100, or for any balance when service ends or the customer moves.
Annual true-upMarch 31 is the annual cash-out balance date; customers with a monetary credit balance exceeding $100 as of March 31 may request payment.
Residential system cap100 kW AC for small customer-generators, including residential and small commercial systems; larger renewable facilities may be eligible up to 1,000 kW.
Commercial system cap100 kW AC for small commercial customer-generators; large customer-generators may be greater than 100 kW and up to 1,000 kW, subject to the tariff's eligibility conditions.
Aggregate program capThe Puc 900 utility-specific capacity allocations are Granite State Electric/Liberty 4.12 MW, New Hampshire Electric Cooperative 3.16 MW, Public Service Company of New Hampshire/Eversource 36.55 MW, and Unitil 6.17 MW; no more than 2 MW statewide may be combined heat and power.
Program statusOpen only within each utility's remaining allocation and on a first-come, first-served basis; the reviewed rules do not establish that every utility currently has unused capacity.
RegulatorThe New Hampshire Public Utilities Commission regulates the investor-owned distribution utilities' net-metering tariffs under Puc 900 and RSA 362-A:9; NHEC's member-elected board sets its tariff.
DocketDE 16-576, the Commission proceeding that adopted the alternative net-metering tariff in Order No. 26,029; Liberty's current tariff also identifies compliance under DE 23-039.
Governing ruleRSA 362-A:9 and New Hampshire Code of Administrative Rules Puc 900, including Puc 903.02 for net-metering measurement, credits, and capacity allocations.
GrandfatheringYes. Customer-generators with a net-metering capacity allocation on or after September 1, 2017 are entitled to the alternative tariff through December 31, 2040; the tariff also preserves applicable terms after qualifying ownership transfers.
Interconnection applicationFile an interconnection application with the distribution utility and, if applicable, the electricity supplier; the application must be submitted by certified mail or with dated receipt verification and include applicant, facility, installation, and certification information.
Interconnection timelineThe utility must notify the customer-generator within 10 business days of receipt whether the application is complete and identify missing information; Eversource says an approved application is typically returned in less than one week.
Pending changeLiberty's DE 26-035 is a pending adjudicative proceeding on a proposed Net Metering Credit Adjustment Mechanism to change how Liberty recovers NEM credits; the filing states the proceeding was commenced and a hearing was set for October 15, 2026.
