CALCULATOR

Use the calculator below to compare your electricity supply costs to those of National Grid’s Basic Service costs, as well as to quantify the environmental benefits of participating in the Greener Option in Westborough Community Choice.

Please note: Your electricity delivery costs (the cost to bring electricity to your home or business) are determined by National Grid and will not be affected by your participation in Westborough Community Choice.

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

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

** Please note that the National Grid Basic Service price shown is the average of National Grid’s Basic Service prices for the past 12 months. Because National Grid’s fixed Basic Service prices change so frequently (every 6 months for residential and commercial accounts and every 3 months for industrial accounts), using an average price provides the most accurate comparison.
