About Net-Metering 

Net-metering is the process of measuring the difference between the electricity supplied to a customer by their utility and the electricity fed back to the utility by a customer’s electric generation system (such as solar panels) during the customer's billing period. In Vermont, customers in the same utility service territory are allowed to form "groups" to share in the output of a net-metering system.

UPDATE - Longer Review Periods Possible for Net-Metering Registrations Filed in Green Mountain Power Service Territory on or After June 27, 2019 

Due to the unprecedented volume of net-metering registrations received at the end of June/early-July 2019, Green Mountain Power (“GMP”) has filed objections into many of these cases. The objections, usually in the form of a letter entitled “Request for Enlargement of Time”, state that GMP needs more time than the usual 10 business days to evaluate these registrations to make sure they can safely interconnect with the grid.

Applicants should be aware that if such a letter has been filed into their registration case on ePUC, their certificate of public good (“CPG”) will not automatically be deemed issued after 10 business days. Pursuant to Commission Rule 5.105(E), when an objection has been filed in a case, the applicant may not start construction of the project until the interconnection issue is resolved. Once the Public Utility Commission (“Commission”) determines that all interconnection issues in a case have been resolved, the Commission will issue an order deeming the CPG issued.
