About Eversource Energy & Energy Choice in CT
Eversource (formerly Connecticut Light & Power) is the largest electric utility in Connecticut, serving over 1.2 million customers in approximately 149 cities. Eversource was founded in 1966 as Northeast Utilities (NU) following the merger of three large New England utility companies. In 2015, the company rebranded all operations as Eversource. This created a single entity that proudly serves customers across Connecticut, New Hampshire and Massachusetts.
Eversource customers receive both their electricity distribution and supply from the utility by default. In 2000, Connecticut passed energy deregulation laws giving its residents Energy Choice and the ability to find better rates. Since then, over 700,000 households and 100,000 businesses in Connecticut have taken advantage of their ability to choose their electricity provider and save on energy costs.

Reading Your Eversource Electricity Bill
Understanding your Eversource electricity bill is critical to managing your energy costs effectively. Your bill is divided into two main components: supply charges and delivery charges.
- Supply charges cover the cost of the electricity you use and can vary depending on your chosen supplier. If you haven’t selected an alternative supplier, these charges will be based on UI’s Standard Service rate.
- Delivery charges cover the cost of transmitting and distributing electricity to your home or business. These charges are set by UI and approved by PURA, and they remain the same regardless of your chosen supplier.
