Exelon Corporation is a utility services holding company engaged in the energy transmission and distribution businesses through its subsidiaries. The company owns and operates regulated electric and natural gas distribution utilities serving millions of customers across multiple states. Its core activities involve purchasing and delivering electricity and natural gas to retail customers within defined service territories while earning a regulated return on infrastructure investments.
Exelon generates revenue primarily through the regulated sale and distribution of electricity and natural gas to end-use customers. The Utility Registrants recover reasonable costs associated with service delivery and earn a return on capital expenditures via commission-approved rate mechanisms. Revenue streams are stabilized by decoupling mechanisms in certain jurisdictions that insulate earnings from fluctuations in delivery volumes caused by weather or usage patterns.

Exelon holds a dominant position as one of the largest regulated utility operators in the United States, serving approximately 10 million electric and gas customers collectively. The company competes with other major investor-owned utilities such as Duke Energy, NextEra Energy, and Southern Company, though its competitive advantage lies in its geographic concentration in high-density, economically significant regions like Chicago, Philadelphia, and Baltimore. Exelon benefits from scale, operational standardization across its subsidiaries, and a constructive regulatory environment that allows for timely cost recovery and infrastructure investment.
Exelon serves a diverse customer base consisting of residential, commercial, and industrial end-users across its service territories. Specific customer segments include households, municipal governments, public institutions, manufacturing facilities, and large commercial enterprises such as data centers and office complexes. The company provides universal service obligation delivery to all customers within its franchised areas, regardless of whether they source energy competitively or through default supply arrangements.
