Electric Delivery Charge and Supply Cost

Your usage impacts both supply and delivery charges. Using less energy can help lower your bill.

What's the Difference Between Delivery and Supply? 

The delivery charge of your bill is made up of three main categories:

  1. Transmission
  2. Distribution, Operations and Service
  3. Public Policy

These components include operating, maintaining and upgrading the electric transmission and distribution systems. Also included is critical customer services and state and federally mandated charges that fund financial assistance, energy efficiency and renewable energy programs.

The supply charge is the cost of electricity you use. We purchase electricity from suppliers on your behalf and pass the cost directly to you, no profit added.

Your Supply Cost

We purchase electricity from third-party suppliers that generate electricity at a power plant or generating station. This is a pass-through cost to customers with no profit to Eversource.  

What is a supplier?

Suppliers generate electricity at a power plant or generating station. We purchase electricity from suppliers and it is transmitted to the electric grid.

All customers have the option of choosing Eversource or another energy supplier to obtain energy on their behalf.

How we determine the supply 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
