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 Greenfield Light & Power.

Please note: Your electricity delivery costs (the cost to bring electricity to your home or business) will not be impacted by your participation in Greenfield Light & Power.

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

* 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 price shown is 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 Greenfield Light & Power 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.
