Eversource Energy is a regulated energy-delivery and water utility serving customers in Connecticut, Massachusetts, and New Hampshire.

[1](https://www.eversource.com/residential/about/our-company) [2](https://www.eversource.com/residential/about/our-company/service-territory)

The company’s footprint is regional rather than global.

## Products & services

Eversource’s customer-facing offerings are primarily regulated utility services rather than branded products. Its current core services include electric distribution, electric transmission, and natural-gas distribution. Customers can receive electricity through utility-procured generation or purchase the commodity from a third-party supplier while continuing to use Eversource’s delivery service. Natural-gas offerings include gas sales and transportation, firm service, and transportation for customers purchasing gas from another supplier. [8](https://app.finbar.com/go?id=P145709790)[9](https://app.finbar.com/go?id=P145710016)[10](https://app.finbar.com/go?id=P49324588)[11](https://app.finbar.com/go?id=P24720356)

Electric transmission work includes line upgrades, new interconnection facilities, and substation construction or enhancements. The gas utilities also use pipeline transportation, storage, balancing, and winter-peaking LNG/LPG facilities to support supply. [12](https://app.finbar.com/go?id=P145709932)[13](https://app.finbar.com/go?id=P104633007) Customer programs include energy-efficiency assistance and rebates, solar-related services, and electric-vehicle charging resources; availability varies by service territory. [14](https://www.eversource.com/residential/save-money-energy/energy-efficiency-programs/)[15](https://www.eversource.com/residential/save-money-energy/efficient-products)[16](https://www.eversource.com/residential/save-money-energy/clean-energy-options/solar-energy)[17](https://www.eversource.com/residential/save-money-energy/clean-energy-options/electric-vehicles)

The 2025 annual report presents revenue by business segment rather than by named product, so it does not provide product-level performance percentages. The 2026 second-quarter report notes that Aquarion’s water-distribution business was sold on June 30, 2026; water services reported for earlier periods are therefore historical.

## Geographic presence

Eversource Energy’s utility operations are concentrated in Connecticut, Massachusetts, and New Hampshire. Its electric distribution utilities serve customers in all three states; its gas distribution operations are in Connecticut and Massachusetts. The company also operates electric-transmission businesses in the three-state region. [20](https://app.finbar.com/go?id=P39705235)[21](https://app.finbar.com/go?id=P33511276)[2](https://www.eversource.com/residential/about/our-company/service-territory)

The company does not disclose revenue by state, country, or geographic region in the materials reviewed; its reported revenue is organized by business segment rather than geography. [21](https://app.finbar.com/go?id=P33511276) Before Aquarion’s water-distribution business was sold on June 30, 2026, it served communities in Connecticut, Massachusetts, and New Hampshire; about 91% of Aquarion’s customers were in Connecticut at year-end 2025. [3](https://app.finbar.com/go?id=P32209854)[19](https://app.finbar.com/go?id=P145709850)

Eversource lists its principal office in Springfield, Massachusetts, and general offices in Boston, Massachusetts, and Hartford, Connecticut. [22](https://app.finbar.com/go?id=P61718529)[23](https://investors.eversource.com/static-files/53b75133-bfcf-48c3-955b-135f61ed3f4e) The company describes its workforce as almost 10,000 employees across New England, but does not provide a state-by-state employee breakdown in the source reviewed.

## Business segments

Eversource reports four operating segments. **Electric Distribution** comprises the rate-regulated distribution businesses of CL&P, NSTAR Electric and PSNH, including NSTAR Electric’s solar facilities; it represented approximately **66.1%** of the four reportable segments’ 2025 operating revenue. **Natural Gas Distribution** comprises Yankee Gas, NSTAR Gas and EGMA, which distribute and sell natural gas in Connecticut and Massachusetts; it contributed approximately **17.3%**. [21](https://app.finbar.com/go?id=P33511276)[4](https://app.finbar.com/go?id=P61249684)[10](https://app.finbar.com/go?id=P49324588)[18](https://app.finbar.com/go?id=T9827454)

**Electric Transmission** comprises the transmission businesses of CL&P, NSTAR Electric and PSNH, which own and maintain facilities on the interstate grid serving New England; it contributed approximately **15.0%**. **Water Distribution** is Aquarion’s regulated water utility business in Connecticut, Massachusetts and New Hampshire; it contributed approximately **1.6%**. [21](https://app.finbar.com/go?id=P33511276)[25](https://app.finbar.com/go?id=P15011515)[3](https://app.finbar.com/go?id=P32209854)[18](https://app.finbar.com/go?id=T9827454) Shares are calculated from 2025 segment operating revenues divided by their combined gross revenue of $15,194.6 million; they exclude “Other” and eliminations, so they are not shares of consolidated revenue. Eversource also presents “Regulated Companies” and “Eversource Parent and Other Companies” in an alternate, non-GAAP earnings grouping.

## Company history

Eversource’s utility roots extend to the mid-19th century, while its modern holding-company lineage took shape in 1966 with the formation of Northeast Utilities from predecessor New England electric companies. [1](https://www.eversource.com/residential/about/our-company) [27](https://www.sec.gov/news/digest/1966/dig041566.pdf) Northeast Utilities expanded into New Hampshire by acquiring Public Service Company of New Hampshire in 1992. [28](https://www.sec.gov/Archives/edgar/data/72741/000110465919025165/a19-8993_1ex4d1.htm) In 1999, NSTAR was formed as the holding company for BEC Energy and Commonwealth Energy System, adding another major New England utility lineage to the later combination. [29](https://www.sec.gov/Archives/edgar/data/1035675/000095013500004504/b36925nre424b2.txt)

Northeast Utilities and NSTAR announced a merger in 2010 and completed it in April 2012, with Northeast Utilities as the parent company. [30](https://investors.eversource.com/shareholder-services/investor-faqs) [31](https://www.sec.gov/Archives/edgar/data/72741/000119312512156349/d333632dex991.htm) Northeast Utilities adopted the Eversource Energy name in 2015. [32](https://www.sec.gov/Archives/edgar/data/13372/000007274116000063/f2015form10k.htm) Eversource broadened its natural-gas distribution operations in 2020 by acquiring Bay State Gas and Columbia Gas of Massachusetts assets. [33](https://app.finbar.com/go?id=P177617489) In 2024, it sold its interests in Sunrise Wind, South Fork Wind and Revolution Wind; it later completed the sale of Aquarion Water Company in June 2026.
