Eversource Energy is a public utility holding company primarily engaged in the energy delivery business through its wholly-owned regulated utility subsidiaries. The company provides electric transmission and distribution, as well as natural gas distribution services to residential, commercial, and industrial customers in Connecticut, Massachusetts, and New Hampshire. Eversource Energy's operations are focused on maintaining and improving infrastructure to ensure reliable service delivery across its service territories.

Eversource Energy generates revenue primarily through the transmission and distribution of electricity and the distribution of natural gas to its customers. The company earns income from base distribution rates, which are regulated charges approved by state commissions to recover costs and provide a return on investment. Additional revenue is derived from tracked distribution revenues related to energy supply procurement, retail transmission charges, state-mandated charges, and wholesale market sales, which are recovered from customers through commission-approved cost tracking mechanisms.

The company operates through the following segments: electric distribution, electric transmission, and natural gas distribution.

• Electric Distribution: This segment is responsible for delivering electricity to end-use customers through a network of substations, transformers, and power lines. It includes the operations of CL&P, NSTAR Electric, and PSNH as the distribution service providers for all customers in their respective service areas. The segment manages advanced metering infrastructure (AMI) programs and grid modernization initiatives to improve system reliability and customer service.
• Electric Transmission: This segment focuses on the high-voltage transportation of electricity from generation facilities to substations for distribution to customers. It involves maintaining and upgrading transmission lines, substations, and related infrastructure to ensure grid resilience and meet growing power demand. The segment supports regional transmission projects such as the Greater Cambridge Energy Program and ISO-NE Longer-Term Transmission Planning RFP to enhance interconnection and reliability across New England.
• Natural Gas Distribution: This segment delivers natural gas to residential, commercial, and industrial customers through a network of pipelines and related facilities. It includes the operations of Yankee Gas, NSTAR Gas, and EGMA as the distribution service providers in their respective service territories. The segment invests in infrastructure upgrades, including cast iron and bare steel replacement, corrosion mediation, and station improvements to enhance system safety and reliability.
