About Solar Power

GMP Solar Power makes electricity out of bright futures.

As part of our continuous effort to encourage the development of renewable sources of energy, GMP offers financial incentives for Vermonters to install solar panels. GMP also makes investments in new solar plants.

To see solar arrays for yourself, we invite you to visit GMP's 264-panel solar array along one of Vermont’s busiest highways, Route 7 in Rutland Town. This array doesn’t just help to cleanly power Vermont, but serves as a working classroom for students and others interested in homegrown, emissions-free energy. Self-directed tours are available at the Renewable Education Center (REC), which includes a walking path through the panels and educational displays that outline all of GMP’s clean energy efforts. Click here to learn more about the Renewable Education Center and/or arrange a guided tour.

To see how a solar plant is built, take a moment to watch the time-lapse video of the construction of GMP’s Berlin Solar Plant.

If you are a net metering customer or you are thinking about installing solar panels, visit the Customer-Owned Generation and Distributed Resources page and the Solar FAQ to learn more about generating your own electricity.

If you still have questions about renewables at GMP after reading our FAQs, please contact the Distributed Resources team at 802.353.2386 or contact by email at
