* This calculator calculates equivalencies using information provided by the EPA’s Greenhouse Gas Equivalencies Calculator. Greenhouse gas emissions avoided are calculating using the most recently available NEPOOL GIS emissions factor.

** Please note that the Eversource Basic Service price shown is the average of Eversource’s Basic Service prices for the past 12 months. Because Eversource’s fixed Basic Service prices change seasonally, using an average price provides the most accurate comparison.

Savings cannot be guaranteed

Please note that, while Watertown Electricity Choice seeks to provide a price that is equal to or lower than Eversource’s average Basic Service price, there is no guarantee of savings compared with Eversource’s Basic Service prices because they change seasonally and future prices are unknown.
