The statute that governs the implementation of net metering in Vermont is Title 30 Section 8010. The law was most recently updated in 2014 with Act 99, when the Legislature directed the Public Utility Commission (PUC) to initiate proceedings to redesign net metering. The current program started January 1, 2017.
Rule 5.100 provides for a biennial review process during which adjustors to net metering compensation and categories can be adjusted. The more recent biennial adjustments order can be reviewed here.
