Energy Innovation Center

Bringing the best in energy innovation and technology to our customers.

The GMP Energy Innovation Center (EIC) located in Rutland, Vermont is the heart of our energy innovation work. Here our team of Energy Advisors work to bring the latest in energy technology and clean energy solutions to our customers. We are driven by our commitment to help customers save money, use less energy and be more comfortable in their homes. Together with our customers, we are partnering on an energy transformation that will change the way we all think about and use energy for decades to come.

The team at the EIC collaborates with many partners, including our in-house neighbors Efficiency Vermont and Neighborworks of Western Vermont.  Together, we are improving the lives of our customers and showcasing many of our innovations right in Rutland, our Energy City of the Future.





GMP is committed to connecting the community more closely with their energy. The EIC is open to the public and we welcome you to visit us to learn more and meet our team.  See a model of our very first eHome, located just blocks away in Rutland’s northwest neighborhood.  Feel (and try to hear) a ductless heat pump in action. Listen to Electra, our talking cow, describe how we make electricity from manure in our Cow Power program.  Learn about the grid of the future that will more efficiently deliver electricity to our homes and increase reliability.

Get inspired and join the discussion. Join us on the first Tuesday of the month, October through May, at 5:30 p.m. for GMP College Connections on energy-related topics hosted by faculty from area colleges. 

Contact us to discuss educational opportunities and/or arrange a tour of the EIC or the Renewable Education Center. Call us at 1-802-770-4088 or email rec@greenmountainpower.com
