* 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 utility Basic Service prices shown are the average of National Grid’s and the average of Eversource’s Basic Service prices for the past 12 months. Because fixed Basic Service prices change seasonally, using an average price can provide a valuable comparison.

Savings cannot be guaranteed

Please note that, while Sharon Power Choice offers the potential for savings when compared with Eversource’s and National Grid’s Basic Service prices, there is no guarantee of savings. This is because the utilities’ Basic Service prices change seasonally, and their future Basic Service prices are unknown.
