Calculator

Use the calculator below to compare your electricity supply costs (the costs of the actual electricity) to your utility’s Basic Service costs, and to quantify the greenhouse gas benefits of participating in the program.

Please note: Your electricity delivery costs (the cost to bring electricity to your home or business) will not be changed by your participation in Sharon Power Choice.

To use the calculator, find your monthly electricity use (in kWh) on your utility electricity bill and enter it into the box below.

(Enter the number of kWh you use in any given month)

* 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 Eversource’s Basic Service prices for the past 12 months. Because fixed Basic Service prices change so frequently (every 6 months for residential and small business/commercial accounts and every 3 months for large business/industrial accounts), 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 every 6 months for residential and small business/commercial customers and every 3 months for large business/industrial customers and future Basic Service prices are unknown.
