Your Privacy

Crucial. Essential. Necessary. Whichever way you say it, protecting your information is extremely important.

A fully functioning and effective smart grid uses information from smart meters to measure demand and detect potential problems or interruptions in service. We are committed to protecting the information we use to optimize GMP Smart Power. We will not release your personal information without your consent unless required by law. Protecting personal information has been an ongoing part of our operations and it is a commitment that is embedded in the GMP Smart Power program. We will continue to use reasonable and appropriate measures to protect your personal information and handle that information in a confidential manner.

Despite the rumor and conjecture of some critics, smart meters will simply tell us whether you are using power and how much you are using. We won’t know what you are using it for, control how you use it, or sell your information to anyone.  This information will only be used to inform how we operate the grid, bill you for your service, and help Efficiency Vermont provide energy efficiency services to you.

Moving forward, we will continue to address any and all privacy issues raised by our customers. If you have any concerns or questions regarding privacy and security issues, please see our Privacy Policy. If you still have questions, head over to our Contact Us page where you can submit questions.
