The town of Westborough is participating in the Community First Partnership offered by the Sponsors of Mass Save. We are working with Mass Save Sponsors, Eversource and National Grid, to provide cost-saving energy efficiency solutions to residents and small businesses in our community.

If you feel your home or small business is too cold in the winter or too hot in the summer and you want to help your community go green, these programs can help.
