We purchase electricity from suppliers that generate electricity at a power plant or generating station. We pass that cost on to customers with no profit added.

What is a supplier?
Suppliers generate electricity at a power plant or generating station. We purchase electricity from suppliers and it is transmitted to substations in the electric grid.
All customers have the option of choosing Eversource or another energy supplier to obtain energy on their behalf.
How we determine your rate
The supply rate is based on the current market price of electricity. This price changes twice each year—on January 1 and July 1 —as demand for energy increases or decreases.
How you're charged
We track your usage in kilowatt hours (kWh). This is a measure of energy use over time. We then multiply your usage by the supply rate to determine your supply charge.
Supply rate x kilowatt hours = supply charge
