Use the calculator below to compare the electricity supply costs of the products offered through the program. The calculator also shows the additional greenhouse gas reductions each product achieves when compared to products that only meet the minimum renewable energy content as set by Massachusetts law, which includes 18% MA Class I RECs.
Please note: Your electricity DELIVERY costs are not affected by your participation in the Program and are not included in these calculations.
You can find your monthly electricity use on the second page of your Eversource bill below the blue “Total Charges for Electricity” bar, under the SUPPLIER section listed as “Generation Service Charge” (kWh X rate).
** Calculated using the information provided by the EPA’s Greenhouse Gas Equivalencies Calculator.
