Usage impacts your delivery charge
Some delivery charges are calculated based on your usage and are charged in cents per kilowatt hour (¢/kWh). We multiply your usage (measured in kilowatt hours) by the rate to determine your charge. Using less energy can lower these charges.
Delivery rate components
There are several components that make up the delivery charge on your bill.
Operating and maintaining the electric grid
Power is generated, transmitted and distributed to customers through the electric grid. These charges help us operate and maintain core components—the transmission and distribution systems.
- Transmission Charge – The transmission system includes the large high-voltage power lines that deliver electricity over large distances from power plants to Eversource’s distribution system. This charge is for operating and maintaining this system.
- Distribution Charge (per kWh) – The distribution system includes utility poles and wires in and around your city or town that deliver electricity to your home or business. This charge is for operating and maintaining this system.
Customer programs and services
These charges fund critical customer services.
- Distribution Customer Service Charge – This fixed monthly fee covers costs related to billing, meter services, customer service and personnel.
Upgrading the electric grid
- Electric System Improvements (ESI) Charge - We make improvements to the electric grid to reduce power outages, shorten restoration times and seamlessly connect cleaner energy sources. This charge funds these investments.
Public policy charges
These items are not controlled by Eversource.
- Combined Public Benefits Charge – This charge collects public policy costs for the Conservation and Loan Management Fund, Conservation Adjustment Mechanism, Renewable Energy Investment Fund, Operation Fuel, Heating Loan Program Boiler Loan Program, Passive Demand Response Program and other low-income energy assistance programs.
- FMCC Delivery Charge - This charge collects public policy costs for the Millstone energy contract, other distributed resource (generation) programs, some long-term renewable energy contracts, The Low-Emission Renewable Energy Credit and Zero-Emission Renewable Energy Credit Programs, Solar Home Renewable Energy Certificate Program and Passive Demand Response Program
These items can appear on your bill as a charge or credit.
- Revenue Adjustment Mechanism – We are authorized by PURA to recover a certain amount of distribution revenue each year. This adjustment allows us to recover money we do not collect (an under recovery) and requires us to issue a refund if we collect more than is allowed (an over recovery).
- Competitive Transition Assessment - This adjustment collects or credits costs related to the sale of Eversource power plants in the year 2000, long term purchase power contracts entered into before 1999 and some cost related to past nuclear power facilities.
