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 opting up to 100% Green Plus.

Please note: Your electricity delivery costs (the cost to bring electricity to your home or business) will not be changed by your participation in the Cambridge Community Electricity Program.

To use the calculator, find your monthly electricity use (in kWh) on your Eversource electricity bill and enter it into the box below. Or enter the median Cambridge residential use of 260kWh, which will be an approximate estimate.

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)
This is the same as driving this many fewer miles in one year*
Participants in both Standard Green and 100% Green Plus also contribute to the development of a new solar project in Cambridge that will avoid approximately 191,000 lbs of CO2 each year. This is equal to avoiding the emissions from driving 214,978 miles in a passenger vehicle.

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

** Please note that the Eversource’s 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.

 

Savings cannot be guaranteed

Please note that, while the Cambridge Community Electricity Program offers the potential for savings when compared with Eversource’s Basic Service price, there is no guarantee of savings. This is because Eversource’s prices change every 6 months for residential and small business customers and every 3 months for large business customers and future Eversource prices are unknown.
