HARTFORD — Northeast Utilities, which operates New England’s largest energy delivery company, has become Eversource Energy.   

All of the company’s subsidiaries, including Connecticut Light and Power Company NSTAR Electric, NSTAR Gas, Yankee Gas Services Company and more will operate under the Eversource brand starting now.  Serving more than 3.6 million electric and natural gas customers in Connecticut, Massachusetts and New Hampshire, and employing a workforce of more than 8,000 New Englanders, Eversource represents one unified company across three states. 

Business and residential customers do not need to take any action as the company becomes Eversource.  All web log-in information will continue to work and customers will be automatically redirected to Eversource.com if they visit the former operating companies’ websites.  No company phone numbers will change.  Customers can continue to call the same phone numbers for account information, outage reporting, moving and any questions.
