AMHERST, Mass. (WWLP) – A new solar array is up and running, putting a key part of Amherst’s electric grid on renewable energy.

Over 15,000 panels are now online in Amherst, and it’s enough to power the electricity of over half of the town’s municipal buildings. The project features a four-megawatt system that spreads across the north landfill.

Stephanie Ciccarello, director of sustainability for Amherst, told 22News this has been ten years in the making, with one of the challenges being that the town wanted to accommodate an endangered species of bird in the area.

Ciccarello added now that this project is a reality, it’s a win-win situation for Amherst. “It helps address the need for more renewables in the state so we feel that we can contribute to the renewable portfolio of the state while at the same time utilizing land that would otherwise not be used other than for the landfill.”

The town estimates the solar panels will generate $100,000 in revenue over a 20-year period.
