Eligibility 

In Delaware, net metering is available to any customer that generates electricity using solar, wind or hydro resources, anaerobic digesters, or fuel cells capable of being powered by renewable fuels. Grid-interactive electric vehicles are also eligible for net metering treatment for electricity that they put on the grid, although these vehicles do not themselves generate electricity. 

System size

The maximum capacity of a net-metered system is 25 kilowatts (kW) for residential customers; 150 kW for farm customers on residential rates (increased by S.B. 111 of 2023); two megawatts (MW) per meter for non-residential customers of Delmarva Power and Light

Washington's net-metering law applies to systems up to 100 kilowatts (kW) in capacity that generate electricity using solar, wind, hydro, biogas from animal waste, fuel cells, or combined heat and power technologies. All customer classes are eligible, and all utilities -- including municipal utilities and electric cooperatives -- must offer net metering.

Net metering is available on a first-come, first-served basis until the earlier of either June 30, 2029 or the first date upon which cumulative generating capacity of net-metered systems equals 4% of a utility’s peak demand during 1996.* At least one-half of the utility’s available aggregate net metering

*Note: The Public Utility Commission currently has a proceeding open (Docket No. 19-0855-RULE) to revise the net metering rules. Final proposed rules were filed in November 2023 and made effective on March 1, 2024.

Vermont's original net metering legislation was enacted in 1998, and the law has been expanded and modified several times. Any electric customer in Vermont may net meter after registering and obtaining a Certificate of Public Good from the Vermont Public Utility Commission (PUC). 

Hydroelectric, ground-mounted PV systems of up to 15 kW, roof-mounted PV systems, and mixed ground-/roof-mounted systems of up to 500 kW

Note: Successor rulemaking for Dominion Energy Virginia's net energy metering rules is in progress in Docket PUR 2023-00069

Net metering in Virginia is available on a first-come, first-served basis until the rated generating capacity owned and operated by customer-generators reaches 1% of an electric distribution company's adjusted Virginia peak-load forecast for the previous year. Net metering is available to customers of investor-owned utilities (including competitive suppliers) and electric cooperatives, but not to customers of municipal utilities. 

Eligibility:

Virginia's net-metering law applies to electric customers who generate electricity from renewable fuel sources* that are up to 25 kilowatts (kW) capacity for

Eligibility and Availability

Oregon state law requires all utilities to offer net metering pursuant to Oregon Revised Statutes 757.300.* Some requirements differ between the state's primary investor-owned utilities (PGE and PacifiCorp) and its municipal utilities, electric cooperatives, and people's utility districts.

Net-metered systems must be intended primarily to offset part or all of a customer’s requirements for electricity. Systems that generate electricity using solar power, wind power, hydropower, fuel cells, landfill or digester gas, biomass resources, geothermal energy, or marine energy are eligible. 

The Public Utilities Commission (PUC) adopted new rules for net metering for PGE and PacifiCorp customers in

NOTE: A.B. 3723 enacted in May 2018 includes several changes to the net metering law, including- i) increase net metered aggregate capacity to 5.8% of the total annual kWh sold in the state, ii) establishes pilot community solar program, and other minor changes. 

Eligibility:

New Jersey's net-metering rules require state's investor-owned utilities and energy suppliers (and certain competitive municipal utilities and electric cooperatives) to offer net metering at non-discriminatory rates to residential, commercial and industrial customers. Systems that generate electricity using solar, wind, geothermal, wave, tidal, landfill gas or sustainable biomass resources, including fuel cells (all "Class I" technologies under

Eligibility and Applicability

Montana's net-metering law, enacted in July 1999, applies to all customers of investor-owned utilities. Systems up to 50 kilowatts (kW) in capacity that generate electricity using solar, wind or hydropower are eligible. No limit on enrollment or statewide installed capacity is specified. Utilities may not require customer-generators to comply with any additional standards or requirements beyond those established by the National Electric Code, National Electrical Safety Code, Institute of Electrical and Electronic Engineers (IEEE), and Underwriters Laboratories (UL).

Net Excess Generation

Net excess generation (NEG) is credited to the customer's next monthly bill. The customer may choose

Ohio's net-metering law requires electric distribution utilities to offer net metering to customers who generate electricity using wind energy, solar energy, biomass, landfill gas, hydropower, fuel cells, or microturbines. Net-metered customers are required to use a single meter capable of recording the flow of electricity in each direction. Under the state's net-metering law, competitive retail electric service (CRES) providers are not required to enter into a net metering contract with a customer. Electric utilities must offer a standard net metering tariff to all requesting customers.

Net-metered systems must meet safety standards specified by the National Electrical Code (NEC), the Institute

Collectors, heat exchangers, and storage units of solar energy systems -- and the installation of these systems -- sold or installed in Arizona must have a warranty of at least two years or guarantee the energy production output for two years. The remaining components of the system and their installation must have a warranty of at least one year. Solar energy systems are subject to random inspections by the state's registrar of contractors.

Any person manufacturing, furnishing for installation, or installing a solar energy system must provide a written statement of warranty, responsibilities assumed or disclaimed, and performance data as

Florida law forbids ordinances, deed restrictions, covenants, declarations or similar binding agreements from prohibiting the use of solar collectors (including clothes lines) or "other energy devices based on renewable resources," although certain restrictions related to visibility may be imposed on property owners, as long as the effective operation of the system does not suffer as a result. Community associations are specifically prohibited from preventing the installation of solar collectors on residential rooftops. Legislation that took effect in July 2008 (HB 697) extended the application of the renewable energy access law to condominiums. Interestingly, a condominium or a multi-condominium board
