Interconnection

https://www.energy.nh.gov/renewable-energy/net-metering-and-group-net-metering/net-metering

Per the New Hampshire Department of Energy's own page: net metering is available to customers of Eversource, Liberty Utilities, New Hampshire Electric Cooperative, and Unitil. For residential and small commercial customers, the equipment's peak generating capacity is limited to 100kW AC, must be located behind the customer's meter, and must be interconnected and operating in parallel with the grid, used primarily to offset the customer's own usage. Compensation specifics vary by utility and project details per the state's Net Metering Tariff.

Confidence: High (0.9)

Permit authority

City of Lebanon Planning and Development Department

New Hampshire's State Building Code (based on the IRC/IBC/NEC with state amendments, most recently updated via HB 1681 in 2022) is adopted statewide but administered and enforced locally by each city/town — a MIXED model similar to several other states researched this session. Lebanon's own Planning and Development Department is the local AHJ.
