Understanding My Electric Bill

Your Eversource electric bill is made up of two parts—supply and delivery.

In accordance with state regulation, our electric supply and delivery rate components are reviewed and adjusted every January 1 and July 1 to reflect the actual cost of purchasing and delivering electricity to our customers.


The supply portion of your bill, also called generation, is the cost of electricity you use. 

How Supply Works

Electricity comes from a pool of energy producers. Eversource purchases electricity from these producers at market price and directly passes it on, with no profit added, to customers on our Standard Service Rate option. This rate changes every six months based on market conditions.

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

How to Decrease Your Supply Charges

You have direct control over the supply portion of your Eversource bill. When you use less electricity, your supply charge will be lower. For some simple ways you can reduce your energy use, see our Energy Saving Tips.

Supply-Related Terms on Your Bill 

You may see these terms on your Eversource electric bill.

  • Supplier Rate - The generation rate charged per kilowatt hour by the supplier.
  • Term - Describes how many bill cycles the supplier rate will apply.
  • Expiration - Meter read date the supplier rate expires.
  • Next Cycle Rate - Supplier rate for your next usage period.
  • Cancellation Fee - Fee for ending a supplier contract prior to its expiration.
  • Standard Service Rate - Current Eversource generation rate.
  • Term/Expiration - Duration of the Standard Service rate and the date it expires.
  • Your Supplier Charge - Total charge from your supplier.
  • Standard Service Comparison - The amount you would have paid at the Standard Service rate.


The delivery portion of your bill, also called distribution, is the cost to deliver electricity to you.

How Delivery Works

Eversource delivers electricity to your home through an extensive distribution network. Delivery charges cover the cost of running and maintaining the system, as well as critical services and programs.

Delivery rates are reviewed and approved by state regulators twice per year.

Components of Your Delivery Charge

There are multiple items that make up the delivery portion of your bill, including taxes and other state and federally-mandated charges.

  • Transmission Charge – This charge is for delivery of electricity over the high-voltage transmission power lines from the generation company to Eversource.
  • Distribution Charge – This is the cost to deliver electricity over poles and wires directly to our customers’ homes and businesses. This includes costs related to maintenance and operation of our distribution system, power restoration and service operations.
  • Distribution Customer Service Charge – This is the cost to operate and maintain our distribution system to safely and reliably serve all customers. This includes costs such as utility poles, power lines, meter services and personnel to provide superior service to our customers.
  • Combined Public Benefits Charge – This charge funds our energy efficiency programs for all customers, as well as assistance programs for residential customers within certain income guidelines. It also helps promote the growth, development and sale of renewable energy.
  • Electric System Improvements (ESI) Charge - This is a delivery service rate component that allows Eversource to recover its investments that protect, strengthen or modernize the electric system.
  • Federally Mandated Congestion Charge (FMCC) - These are costs that promote system reliability, such as generation support during periods of high demand.
  • Revenue Adjustment Mechanism – An adjustment that reconciles annual actual distribution rate revenue amounts to the pre-established level of distribution rate revenue required.

Estimated Bills

If you receive an estimated bill, the amount due on the bill is an approximation of your monthly electric use based on past bills and usage.

Normally our meter readers directly get an actual read from your meter each month. However, there are times when this isn't possible - either because the meter is located inside and you are not home to provide access, inclement weather, obstacles blocking the meter (such as shrubs) or some other unusual situation.

Upon receiving an estimated bill you have two options:

  • Wait for your next scheduled meter read and bill. After an Eversource employee makes an actual read of your meter, your next bill will be adjusted to reflect your actual usage.
  • Read the meter yourself and call us at 800-558-7323 with your use. It is easy to do and we'll send a revised bill immediately.
