The system on the old landfill went live on April 14, 2016 and in fiscal year 2017 brought in $317,000 in solar credits, which is used to offset municipal electricity bills.
The Solar PV Panels Exploratory Committee studied additional areas in town for a second installation and moved towards a rooftop installation at the Public Work building. This went live over the summer of 2017. It is a smaller installation and is anticipated to bring in an additional $21,000 in solar credits annually.
Net Metering (Solar) 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 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.
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.
