Eversource History

Eversource was founded in 2012 as a result of a merger with Northeast Utilities (including Connecticut Light & Power (CL&P), Public Service of New Hampshire, Western Massachusetts Electric (WMECO), and Yankee Gas) and NSTAR Electric & Gas.

They rebranded from the Northeast Utilities name to Eversource in 2015. Although Eversource Energy is a relatively new name on the electricity scene in Connecticut, this is not a company that’s new to electric utilities.

Eversource Service Areas

Within Connecticut, they provide electricity transmission and distribution services to almost the entire state. This means they maintain the wires, poles, and electrical infrastructure for most of the state of Connecticut.

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

Eversource Awards & Recognition

Eversource is nationally known as one of the nation’s premiere utilities. They have been recognized twice in the last four years as a top-ranked green utility by Newsweek based on environmental impact. In addition, Business Insider recognized them as a Best Company to Work for in America based on salary, job satisfaction, and high job meaning.

They have received the EPA’s ENERGY STAR Partner of the Year Award repeatedly for various home efficiency efforts. Also, Eversource has received numerous Emergency Recover Awards from the Edison Electric Institute for outstanding power restoration efforts in recent storms.

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.
