Calculator

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

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

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

* This calculator calculates equivalencies using information provided by the EPA’s Greenhouse Gas Equivalencies Calculator.

** 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 so frequently (every 6 months for residential and small business accounts and every 3 months for large business accounts), using an average price provides the most accurate comparison.

Program prices were lower than the average Eversource Basic Service price from program launch through June 2020. However, because Eversource’s Basic Service prices beyond June 2020 are unknown, savings can’t be guaranteed.
