* 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 Walpole Power Choice offers the potential for savings when compared with Eversource’s Basic Service prices, there is no guarantee of savings. This is because Eversource’s prices change seasonally, and future Eversource prices are unknown.
