Exelonについて

Exelon Corporation is a pure-play regulated transmission and distribution utility holding company headquartered in Chicago, delivering electricity and natural gas to customers across the mid-Atlantic and Midwest. It operates through six regulated utility subsidiaries: Commonwealth Edison serving northern Illinois, PECO Energy in southeastern Pennsylvania, Baltimore Gas and Electric in central Maryland, Pepco in the District of Columbia and suburban Maryland, Delmarva Power on the Delmarva Peninsula, and Atlantic City Electric in southern New Jersey. Revenue comes overwhelmingly from delivering power and gas over its wires and pipes rather than generating or selling the commodity itself, with rates set by state regulators. Commonwealth Edison, serving the Chicago metropolitan area, is typically the largest contributor to consolidated earnings.

Investors watch the company primarily through the lens of regulatory outcomes across its six jurisdictions, since allowed returns on equity, rate case cadence, and the treatment of capital investment set the ceiling on earnings growth. Rate base expansion tied to grid modernization, transmission build-out, and electrification underpins the capital plan, so the durable questions concern how much of that spend regulators permit to earn a return and on what timeline. Other structural considerations include exposure to Illinois legislative and formula-rate mechanics, Federal Energy Regulatory Commission transmission policy, weather-normalized load trends, financing needs at investment-grade cost, and governance features shaped by the company's post-separation focus on wires-only economics.

Exelon was formed in 2000 through the merger of Chicago-based Unicom, parent of Commonwealth Edison, and Philadelphia-based PECO Energy. The company subsequently absorbed Constellation Energy Group in 2012, adding Baltimore Gas and Electric alongside a large competitive generation and retail supply business, and in 2016 acquired Pepco Holdings, bringing Pepco, Delmarva Power, and Atlantic City Electric into the group. The defining recent transformation came in February 2022, when Exelon separated its competitive generation and customer-facing energy businesses into a standalone company, Constellation Energy Corporation, leaving Exelon as a purely regulated transmission and distribution utility holding company. It today functions as the parent of the six delivery utilities under a single corporate structure.

Mechanically, the company earns revenue by charging tariffed delivery rates to residential, commercial, and industrial customers connected to its distribution networks, with transmission revenue collected through FERC-jurisdictional formula rates. Retail customers may buy the underlying commodity from competitive suppliers or from the utility on a pass-through basis, so the utilities are largely indifferent to commodity price levels and earn on the volume and value of the delivery infrastructure they operate. Competitive position rests on exclusive franchise service territories, regulated monopoly economics, and scale in capital deployment rather than on product differentiation. All revenue is generated in the United States, concentrated in Illinois, Pennsylvania, Maryland, New Jersey, Delaware, and the District of Columbia, positioning Exelon among the largest U.S. utility holding companies alongside NextEra Energy, Duke Energy, and Southern Company.
