Carve-out: Solar 0.3% of customer load by 2024
Tracking system: New England Power Pool Generation Information System (NEPOOL-GIS)
New Hampshire has a renewable portfolio standard (RPS) requirement of 24.8% by 2025. It has a solar carve-out, which is maintained annually at 0.3% from 2014 to 2025. Solar alternative compliance payment has been on the same level as other renewables since 2013. New Hampshire passed a bill in May 2016 to increase renewable energy deployment and double its net energy metering capacity to 100 MW. Another bill was passed in March 2016 to streamline the interconnection process, creating fast-track interconnection for systems smaller than 100 kW. Group net metering legislation allows community solar projects to be implemented. New Hampshire Public Utilities Commission's (NHPUC) administers a rebate program for commercial and industrial customers.
- While the successor to the current net metering tariff is under formulation, the NHPUC aprproved to have existing net metered systems—as well as those placed into service before a successor program comes into effect—to be credited at current rates through December 31, 2040. For systems less than 100 kW, the only change is that the distribution service charge will be credited at 25% of the full rate instead of 100%.
In May 2016, a bill doubled the state aggregate net-metering cap to 100 MW. 50 MW was allocated to four electric distribution companies while another 50 MW was allocated to the three investor-owned utilities (IOUs). 80% of each utility's share is reserved for small customer generators up to 100 kW and 20% of each utility's share is reserved for large customer generators between 100 kW and 1 MW.
The 2016 bill also directed the NHPUC to develop new alternative net electric metering (NEM) tariffs within the next ten months. Until these tariffs are approved, 50 MW of capacity would be made available to eligible customer-generators. If a utility passes its cap limit before alternative NEM tariffs are adopted they can continue to interconnect using temporary NEM tariffs under the same terms and conditions as net metering under the 100 MW cap. The bill requires each utility's NEM tariff to be identical with respect to rates, rate structure, and charges, as applicable to a customer for its services from the utility. Current NEM tariffs would be available until the end of December 2040. Net excess generation credits do not expire and can be reimbursed at the end of the annual year at the utility's avoided cost rate.
System size limit: 1 MW
Aggregate cap: 100 MW
Credit: Excess generation carried forward as kilowatt-hour credit, may receive avoided cost rate payment at the end of the year.
RECs: Customers retain ownership of renewable energy certificates (RECs).
Meter aggregation: Virtual net metering is allowed.
Interconnection procedures differ for large and small customer-generators. Large customer-generators are governed by the utility's interconnection practices. The small customer-generator interconnection provisions guided by the NHPUC include timelines for the application process and inspection process, and guidance for technical studies and analysis (if necessary). All projects >10 kW undergo a witness test unless waived by the distribution utility. For small customer-generators, a single meter measures the inflow and outflow of electricity whereas a bidirectional meter is used for large customer generators.
In March 2016, a bill outlining uniform and consistent procedures for interconnection queue processing for net-metered customer-generators was passed. This was required to be implemented by the three state IOU's within 30 days of the date of issue (see below).
|Eligible Systems||Type of Interconnection|
|≤10 kW||Required to meet minimum application requirements only|
|>10 kW and ≤100 kW||Required to meet minimum application requirements and complete a supplemental review agreement|
|>100 kW and ≤1 MW||Meet an extensive set of requirements|
System capacity limit: 1 MW
Liability insurance: Property insurance or comprehensive personal liability insurance not required, but an indemnity agreement is generally required.External disconnect switch: Not required for inverter-based systems complying with the IEEE 1547 & UL 1741 technical standards.
Third Party Ownership
Third party solar power purchase agreements are allowed in New Hampshire.
NHPUC permits group net metering, which allows practicing community solar. A customer-generator is allowed to be a group host for a group of customers who are not generators. The kWh credits generated by a host system can be shared within the group under a contract arrangement. Upgrade costs to accommodate billing for group net metering are to be borne by the group host. For more information on local community solar programs please contact local utilities and service providers.
State Incentive Programs
