History of Eversource
- Founded: 2015
- Founders: Northeast Utilities (corporate rebranding)
The Eversource brand is young, but the utilities behind it built New England's first large power systems. Connecticut Light and Power, Western Massachusetts Electric, and Holyoke Water Power merged in 1966 to form Northeast Utilities, a holding company that shared financing and management across state lines.
Northeast Utilities spent decades as a solid if unglamorous regulated utility. It absorbed the bankrupt Public Service Company of New Hampshire in 1992 and gradually divested most of its power generation, refocusing on wires and pipes. The 2012 merger with NSTAR, a Boston electric and gas utility, doubled its size and created the largest energy delivery company in New England.
The rebrand followed in April 2015. Northeast Utilities renamed itself Eversource Energy and unified CL&P, NSTAR, PSNH, and the rest under one customer-facing name. The stated goal was a single identity for a customer base that had known four different utility names.
The brand's next chapter was defined by subtraction. Eversource spent billions partnering with Orsted on offshore wind development starting in 2016, then sold its 50 percent stakes in South Fork Wind and Revolution Wind to Global Infrastructure Partners in September 2024 at a large loss. The Aquarion water utility, acquired in 2017, was sold to the newly formed public Aquarion Water Authority on June 30, 2026, for $2.4 billion. What remains is a pure-play electric and gas wires business.
