What the law says
Act 149 (S 202) was signed on June 16, 2026 and took effect on July 1, 2026. A customer may install one or more plug-in devices per electric meter if their combined inverter capacity is not more than 1,200 W. Devices may only be connected where the home has a smart meter, and each must be securely attached to the ground or a structure.
A device must comply with UL 3700 or an equivalent certification by an equivalent nationally recognized testing laboratory, be installed and operated under IEEE 1547-2018, and must not energize the building during an outage. A utility may not require its approval, a fee related to the installation or extra equipment, and no interconnection agreement is needed. The utility may still recover costs if a device overloads the service.
Exported power is not paid, and a customer with net metering may not also install a plug-in device. A tenant gives the landlord at least 10 days’ notice; the landlord may answer within 10 days with reasonable restrictions, such as requiring a licensed electrician for any electrical work, and if it does not answer the tenant may go ahead. Deed restrictions and covenants may not prohibit a plug-in device.
- Size: 1,200 W of combined inverter capacity per electric meter.
- Certification: UL 3700 or an equivalent certification; IEEE 1547-2018.
- Exports: not paid; not combined with net metering.
Before you buy in Vermont
Check three things before you buy: the product’s certification, your landlord’s or association’s rules, and your meter. The law asks for UL 3700 or an equivalent certification, so check the product listing or the certifier’s database; a seller’s own claim is not a listing. Ask your utility whether your home has a smart meter, since devices may only be connected to systems with one.
If you rent, give your landlord at least 10 days’ notice before you install. The landlord may answer with reasonable restrictions, and any electrical work needs the landlord’s permission. Covenants may not prohibit a plug-in device, but placement rules may still apply.
The calculator gives real production and savings numbers for Vermont. An 800 W kit, vertical and facing south, produces 657 kWh in a typical year; 401 kWh (61%) is used at home and 256 kWh goes to the grid, and the home-used power is worth $96 a year at Vermont’s 23.95 cents/kWh. Tilted at 30° the same 800 W kit produces 948 kWh a year and saves $116. A 1,200 W kit, vertical and south, produces 985 kWh a year and saves $107 (the calculator results are site-computed).
- Confirm a UL 3700 listing or an equivalent certification on the certifier database
