Customer-Owned Generation and Distributed Resources

Do you want to generate your own electricity? 

If you're a Green Mountain Power customer looking for information about interconnecting your own generation to the grid, you've come to the right place. After reviewing the resources outlined below, please contact our team directly at or call 802.770.3399 if you need further assistance.

There are several choices when considering interconnecting your generation source. The easiest way to separate them is by size as well as how you'll be compensated for the power you produce.

Net Metering - You are the Grid

"Net Metering" is the term used to describe how Vermonters can generate their own electricity and send what they don't use back onto the grid. If a net metered customer uses more electricity than is generated, the customer will pay the utility only for the difference. If the system generates more electricity than the customer used in a month, Green Mountain Power records a credit towards the customer's next bill. However, net metering is intended to allow customers to generate enough for their own use, but not to exceed their own use. Excess net metering credits that are more than one year old will expire.
