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.

NOTE: From the Newton Power Choice launch in March 2019 through May 2020, Newton residents and businesses bought renewable electricity that matched more than 271 million kWh of electricity use. 271 million kWh of electricity equates to 94.8 million pounds of CO2, which is roughly equal to 106 million fewer miles driven by passenger vehicles such as cars, pickup trucks, SUVs, and vans.

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.

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

Newton Power Choice Costs and Benefits
Standard Offering (default)
80% renewable electricity (including the 18% required by State law), all from New England
 100% Green (option)
100% renewable electricity, all from New England

Program price ($/kWh) $0.13452 $0.14357 $0.10646
Monthly electricity supply charges ($/month)

If you participate in the program for one year, this will be your approximate greenhouse gas reduction over the course of that year:
Greenhouse gas emissions avoided in one year compared to Eversource's Basic Service (lbs/year) 0
This is the same as driving this many fewer miles in one year* 0

* 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.
