The Town of Woolwich Solar Array

The town’s solar array sits on the former town landfill off Middle Road. It is a 24-kilowatt array of about 80 panels, built by ReVision Energy, and it supplies about 70% of the electricity used by the town’s buildings. In the 2024 fiscal year it produced 28,676 kWh.

The array went online at the end of December 2017, with a ribbon-cutting in January 2018. In its first year it produced just under its target of about 30,000 kWh, held back slightly by shading.

It was built under a power purchase agreement: a private owner paid for and owned the array, which let it use federal tax credits the town could not, and the town bought its electricity, with the option to buy the array later. Town meetings set money aside in a solar reserve for that purchase. The Select Board approved the buyout on March 5, 2025, and the purchase was completed at the end of June 2025.

The town now owns the array outright. Its electricity no longer has to be bought, which saves the town several thousand dollars a year.
