Price calculator

Use the calculator below to compare the cost of participating in Chelsea Electricity Choice to Eversource’s Basic Service and to quantify the greenhouse gas benefits of participating in Chelsea Standard or Chelsea 100% Green.

The Eversource Basic Service prices shown are the average of Eversource’s Basic Service prices for the past 12 months. Because fixed Basic Service prices change seasonally, using an average price can provide a valuable comparison. Visit the Options & Prices page to see Eversource’s current Basic Service prices.

Please note: Chelsea Electricity Choice impacts only your Supply cost (the cost of the electricity you use). Your Delivery cost (the cost to bring electricity to your home or business) will not be changed by your participation in Chelsea Electricity Choice.
