    Connecticut Light and Power (CL&P) was previously part of Northeast Utilities. That company included CL&P, Public Service of New Hampshire, Western Massachusetts Electric (WMECO) and Yankee Gas. In 2015, Northeast Utilities changed their name to Eversource. So, Connecticut Light and Power is now Eversource Connecticut.

    Eversource CT serves 149 towns in Connecticut. Their territory covers 4,400 square miles. Cities served include Hartford, West Hartford, Stamford, New Britain, Greenwich, Danbury, and Waterbury

    What are the benefits of choosing an electricity supplier in Connecticut?

    Eversource rates change twice annually. When you choose an electricity supplier in CT, you can lock in a fixed electricity rate for your home or business. That gives you price certainty. And consumer protections allow you to cancel your residential contract with no penalty. That way if the CT utility price drops, you can switch back with no charge.

    Utility Highlights

    Eversource Energy is an electricity customer-focused Connecticut utility combining technology and experience to anticipate and address problems of all types before they become unmanageable crises. Since their merger, they have invested heavily in infrastructure, automation and people to make this electricity utility more reliable than ever, even during major storms.

    Eversource has a plan to prevent and manage all sorts of electricity-related problems. Here are a few ways the Connecticut utility is trying to help before little issues become big electricity outages:

    • Financial assistance programs. They recognize the importance of electricity for customers across Connecticut, even if they’re having trouble paying their past due or current bills. That’s why they offer customers a variety of financial assistance plans, as well as weatherization assistance to help reduce future bills.
    • Real-time outage tracking. They provide real time outage tracking via an their online outage map as well as online account resources for customers to view their specific outage status.
    • Equipment inspections. Besides doing hands-on inspections of equipment on the ground, they monitor equipment from the sky using infrared scanning equipment and helicopter fly-over inspections. This way, trained inspectors can quickly identify problematic equipment even in remote areas of Connecticut that might otherwise not be caught until the grid goes down.
    • Improving infrastructure. Electrical hardening, involving replacing old copper wires with thick, rubber-coated wires that are more weather and tree-resistant, and structural hardening, which is the installation of stronger power poles and hardware that’s more durable, are just the beginning of infrastructure improvements they have in progress. Automation investments are also helping to monitor the grid for problems so a repair expert can be notified immediately.

    Customers living in areas of Connecticut served by Eversource can select an alternative energy supplier and get excellent CT energy rates. Eversource will continue to serve customers as the local utility and bill customers in the same manner without interruption in service.
