Suppliers generate electricity at a power plant or generating station. We purchase electricity from them, 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

This is our core business – safely and reliably delivering power to your home. Since 2019, on average the cost of  a utility pole has increased nearly 30%, transformer has increased about 130% and a spool of distribution wire has increased nearly 50%. 

Beyond delivering the power to you, this service includes the cost of skilled employees that operate and maintain the local system of poles and wires and provide customer service. It also includes the cost of improvements to make the electric grid more resilient and reliable. 

Unlike a flat charge for the delivery of a package, the local delivery charges on your energy bill are driven by how much energy you use and can vary from month to month.   

Line items on your bill that fall into this category include: 

• Fixed Monthly Charge - Eversource operates and maintains its electric distribution system to safely and reliably serve our customers. This charge includes the cost for poles, wires, meters and personnel needed to provide service to customers.
• Local Delivery - This is the cost of Eversource to build, maintain, and repair the poles, lines, and meters that deliver power from the substation. It is regulated by the Connecticut Public Utility Regulatory Authority (PURA).
• Local Delivery System Improvements –This is a rate component that allows Eversource to recover its investments that protect, strengthen, or modernize the electric grid.
• Revenue Decoupling – This balances the difference between the amount Eversource is allowed to collect for energy delivery during a specific period for its operating costs, and how much was actually collected at the end of that period.
• Competitive Transition Assessment (CTA) Charge – These are costs associated with deregulation. Regulators approved the costs before electric utility deregulation in 1998 and ensured continued cost recovery in a deregulated market.
