Eversource Energy

What Eversource Energy does

Eversource Energy is a publicly traded regulated utility holding company (NYSE: ES) headquartered in Hartford, Connecticut, founded in 1966 and operating across Connecticut, Massachusetts, and New Hampshire. The company transmits and delivers electricity and natural gas, and historically water, to more than 4.6 million customers through franchised service territories protected by state regulatory frameworks (PURA, DPU, NHPUC). Core operations are conducted through wholly owned subsidiaries including NSTAR Electric (Massachusetts electric distribution), Yankee Gas and Eversource Gas of Massachusetts (natural gas distribution), and Revolution Wind (offshore wind).

The company's infrastructure includes Advanced Metering Infrastructure (AMI) with smart meters capturing 15-minute interval usage data, grid-scale battery energy storage systems, fiber optic grid control networks, and a pilot networked geothermal heating and cooling network. Major capital projects include the Huntsbrook Energy Hub (2,400 MW offshore wind interconnection, supported by an $89 million DOE grant) and the Revolution Wind project targeted for commercial operation in the second half of 2026. Eversource is currently transitioning to a pure-play regulated electric utility model following the divestiture of Aquarion Water Company ($2.4 billion, approved March 2026) and the Massachusetts natural gas distribution business (April 2026).

Eversource operates under a regulated rate-base revenue model, earning an authorized return on equity on capital investments recovered through rates approved by state utility commissions. Revenue streams include regulated electric and gas distribution, water distribution, renewable energy projects, and energy efficiency programs, with tariffs structured across residential, commercial, industrial, and municipal customer segments. The company has guided to 5% to 7% annual earnings growth through 2030, supported by a $26.5 billion capital investment plan for 2026-2030.
