Calculator

Use the calculator below to compare your electricity Supply costs (the cost of the actual electricity) to Eversource’s Basic Service costs, and to quantify the greenhouse gas benefits of participating in Standard Green or opting up to 100% Green.

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 Natick Electricity Aggregation Program.

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

Natick Electricity Aggregation Program Costs and Benefits
	Standard Green (default) 25% renewable electricity (MA Class I RECs) added in addition to the minimum required by state law	100% Green (option) 100% renewable electricity (MA Class I RECs)	Natick Basic/Brown (option) only the minimum amount of renewable electricity required by state law
Program price ($/kWh)	$0.15561	$0.17474	$0.14680
Monthly electricity supply charges ($/month)
Your environmental impact after one year of participation in the program will be equivalent to:
Avoiding this many pounds of CO₂			0
Driving this many fewer miles*			0
Compare to Eversource's Basic Service price (the most recent 12-month average**)
	Residential	Small Business	Large Business
12-month average Eversource price ($/kWh)	$0.14507	$0.14378	$0.14685
Monthly electricity supply charges ($/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 Eversource Basic Service prices shown are the average of Eversource’s Basic Service prices for the past 12 months. Because Eversource’s fixed Basic Service prices change seasonally, using an average price provides the most accurate comparison.

Savings cannot be guaranteed

Please note that, while the Natick Electricity Aggregation Program offers the potential for savings when compared with Eversource’s Basic Service prices, there is no guarantee of savings. This is because Eversource’s prices change seasonally and future Eversource prices are unknown.
