Whenever the royal monarch of Britain dies, his or her government is tasked with changing the emblems of their reign across the reach of the empire. Mailboxes and passports emblazoned with the initials of the Queen are changed slowly. They are altered only as they require updating, regardless of the monarch\u2019s death. Eversource Energy, formerly known as Northeast Utilities, doesn\u2019t have that same luxury as it quietly launches a new brand across three states. \u201cTalk about an undertaking,\u201d spokesman Mitch Gross said Thursday. \u201cWe had to get new security badges for 8,000 employees in three states, and 200-plus new signs in 70 locations in three states. We\u2019re rebranding 3,800 vehicles, and now six websites merged into one.\u201d As of Feb. 2, divisions formerly known as Yankee Gas,\u00a0 Connecticut Light & Power, Public Service Co. of New Hampshire, Western Mass. Electric, and NStar, as well as the parent company, Northeast Utilities, all fall under the same name: Eversource Energy. Nothing about customers\u2019 billing and payment process will change, though envelopes and electronic bills will now bear the new logo of Eversource. Divisions like Yankee Gas will now be referred to only as Eversource Energy. Though the rebranding process has been in the works for 18 months, some industry professionals questioned the company\u2019s rollout of the new name. \u201cNU missed an epic opportunity here,\u201d wrote Greg Davis, of Mascola Group, a New Haven-based marketing firm. \u201cThey have been understandably quiet about their plans since pieces of the rebranding began happening over the past year, but to dismiss the goodwill both internally and externally that the launch of a new brand brings seems alienating.\u201d Regardless of what seemed to be a quiet rollout, Mr. Gorss said one of the most important drivers for the name change regarded the opening of new avenues for the company. \u201cWe deliver natural gas and electricity, but we also stay current with technology,\u201d he said. \u201cIt\u2019s a streamlined approach, but it\u2019s also more broad in scope\u2026 We\u2019re no longer restricted just to light and power. Everything has to be regulatory approved, but the old names limited us. This doesn\u2019t. This gives us more opportunities to build on what we\u2019ve been building on.\u201d Also important, he said, was giving customers and employees a \u201cone company, one name\u201d approach to branding. \u201cWhen NU and NStar merged, there were six different companies operating in three states each with a different name. Since that time, our focus has been on integrating companies and improving how we did business. Operating as one brand is a more effective way to do business,\u201d Mr. Gross said. \u201cIt streamlines things for the company and for consumers as well. There\u2019s no longer a question of who your natural gas company is.\u201d The cost for the company\u2019s rebrand was paid by shareholders, Mr. Gross said, noting none of the process was funded by customers. Specifically, the new logo was designed to represent the three states in which Eversource operates, and the three services it provides. The official name of the company is Eversource Energy, but Eversource is an acceptable shortened version, Mr. Gross said.
