Vermont has established an expedited permitting process for solar photovoltaic systems that are 15 kilowatts-AC (kW) or less. In order to interconnect and net meter, electric customers in Vermont must obtain a Certificate of Public Good from the Vermont Public Service Board (PSB). Solar net-metered systems that are 15 kW or less follow an expedited process for the Certificate of Public Good. To receive a Certificate of Public Good, the customer must register the system with the PSB. The customer must inform the PSB about the project and comply with the electric utility’s interconnection requirements. If there are any issues with the system’s compliance with interconnection requirements, the utility must raise these issues in a letter within 10 business days. If the utility does not raise any issues within 10 business days, a Certificate of Public Good is automatically "deemed issued," and the customer may proceed with installation.
Vermont also offers an expedited process for net-metered solar PV systems greater than 15 kW that are mounted on a roof. If the utility does not raise any issues within 30 business days, a Certificate of Public Good is automatically "deemed issued," and the customer may commence construction.
