The system went live on April 14, 2016. The Solar PV Panels Exploratory Committee is currently working towards a rooftop installation at the Public Work building.
Net Metering Credits & Additional Savings
As part of the power purchase agreement, the Town receives 1 net metering credit for each kilowatt-hour of electricity generated by the solar array and received by Eversource (Nstar) over the course of the 20-year lease. These credits are applied to the electric bill received by the Town, thereby reducing how much money is spent on electricity used by the municipality and saving tax dollars. The first year is projected to save $345,000. The second installation is anticipated to be completed in 2017 and is expected to produce an annual $21,000 in savings.
Ameresco established a live-monitoring site, so interested residents can track the energy being produced, as well as the environmental impact equivalents. To visit the site, please follow this link, or observe below.
