Working Better Together

The People of GMP generate more than just electricity

Our team of dedicated Vermonters work hard everyday to deliver on our promise of highly reliable, cost-effective, clean energy for the families and businesses of Vermont.

Community Leaders. We care about our friends and neighbors all across Vermont. That's why we invest in programs and services that make our state stronger. From the Gift of Life Marathon to Green-Up Day, Rutland Blooms, the United Way, and so much more GMP gives generously to these worthwhile causes because these organizations support our communities. More importantly though, is our people who give hours of their time and talent by staffing events, beautifying our roadways and cities, and organizing staff donations. We believe that Vermont is the best place to live and work and are proud to make our state better together.









Bright Future. Green Mountain Power is leading the state and our nation with cutting edge, clean energy and alternative energy technologies to bring down costs for our customers and improve our quality of life. From new wind and solar energy generation to small scale hydroelectric to electric vehicle infrastructure, smart meters, heat pumps -- if it will make life better for Vermonters, we will work hard to bring it to you. As Vermonters, we care about our energy future and we care about delivering lower cost energy. The future is bright and we are excited to be a part of that future.

These Green Mountains are our home. That is why we work so hard to ensure a clean environment for this generation and future Vermonters. We have conserved thousands of acres of land, protecting wildlife and habitat. We partner with Vermont dairy farmers to help them turn methane waste from their cows to energy for our customers. And when we learned that our Middlebury hydro facility was home to the endangered Little Brown Bat, we teamed up with state officials to ensure they were safe and protected at our site. Our people are committed to preserving the beauty of Vermont's cherished natural landscape.


Safety and Storm Response. No matter the season or time of day, our crews take safety and storm response seriously. You can count on us to respond quickly to outages and do what ever it takes to get the lights back on. And when the sun is shining we are taking steps to reduce and shorten outages through the installation of a smarter grid and by clearing poles and lines of hazards.
