History
[edit]Exelon Corporation was created in October 2000 by the merger between PECO Energy Company, formed in 1902, and Unicom Corporation, the parent of Commonwealth Edison, formed in 1907.[3] Unicom was based in Chicago and the city became the headquarters of the new entity. The merger was overseen by the CEO of Unicom, John Rowe, who joined the corporation in 1998 and led the newly formed Exelon until 2012, becoming the nation's longest-serving utility executive.[3][4][5]
On July 31, 2005, the Federal Energy Regulatory Commission approved the merger of Exelon and Public Service Enterprise Group, a New Jersey utility;[6] however, after 18 months, the two companies terminated the agreement due to pressure put on the New Jersey Board of Public Utilities by public interest groups, including New Jersey Citizen Action.[7][8]
On March 12, 2012, Exelon acquired Constellation Energy, with the combined company owning more than 34 gigawatts of power generation (55% nuclear, 24% natural gas, 8% renewable including hydro, 7% oil and 6% coal).[9][10]
Exelon announced the proposed purchase of Pepco Holdings on April 30, 2014, for $6.8 billion in an all-cash transaction. The merger faced stiff opposition from community groups and D.C. Mayor Muriel Bowser.[11] The merger was originally rejected by the District of Columbia Public Service Commission in August 2015, though it was approved by other federal and state regulators. The companies appealed the decision.[12] On March 23, 2016, the merger was finally approved by the District of Columbia Public Service Commission after the company made concessions and the merger was completed, making Exelon the largest regulated utility in the United States by customer count and total revenue.[13]
On February 2, 2022, Exelon completed the corporate spin-off of Constellation Energy, its energy generation business.[14] Constellation was the largest operator of nuclear power plants in the United States and the largest non-governmental operator of nuclear power plants in the world. It is also the largest competitive U.S. power generator with approximately 35,500 megawatts of owned capacity. It had full or majority ownership of 23 nuclear reactors in 14 nuclear power plants.[15][16]
Controversies and legal issues
[edit]PECO Energy: Nuclear power protests and solar energy expansion
[edit]In the 1970s, activists delayed the opening of nuclear power plants by PECO Energy.[17]
In 2015, Earth Quaker Action Team began a campaign to pressure PECO to expand the solar power it purchases, and to purchase it locally to create jobs.[18]
Pollution, security incidents
[edit]In 2005, Exelon was required to pay a $602,000 fine for exceeding the permitted sulfur dioxide emission limit from April to October 2004 at its Cromby Generating Station in Chester County, Pennsylvania.
Exelon and Illinois state officials waited for four years until 2006 before disclosing that Exelon's Braidwood Nuclear Generating Station, a nuclear plant 60 miles southwest of Chicago, had spilled millions of gallons of water containing tritium, a radioactive form of hydrogen, multiple times over a decade. Exelon officials eventually apologized and said the risks from the leak were "minimal", with tritium levels in surrounding wells all found to be below regulatory limits.[19][20]
In 2009, the Nuclear Regulatory Commission announced its plan for a $65,000 fine against Exelon for permitting its contracted security guards that were guarding its Peach Bottom Nuclear Generating Station, a two-reactor nuclear plant located in Delta, Pennsylvania, to sleep on the job. The incidents did not come to light until a videotape of the security guards was leaked to news media.[21] As a result, Exelon terminated the security contract of the Wackenhut security firm that had been involved and now operates its own in-house nuclear security force.[22]
Political activity
[edit]Exelon makes political contributions via its political action committee (PAC), EXELONPAC. In 2021 and 2022, it contributed $323,500 to federal candidates, including $202,500 to Democrats and $121,000 to Republicans.[23] In 2022, it spent $2,878,000 on lobbying.[24]

Formation and Early Development
Exelon Corporation was formed on October 20, 2000, via the merger of PECO Energy Company and Unicom Corporation, establishing a major utility holding company serving electric and gas customers in the Mid-Atlantic and Midwest regions.[18] PECO Energy traced its origins to the Philadelphia Electric Company, incorporated in 1902 to supply electricity in southeastern Pennsylvania, evolving into a key regional provider with a focus on urban distribution networks.[19] Unicom Corporation, the holding company for Commonwealth Edison—formed in 1907 through the consolidation of Chicago-area utilities by Samuel Insull—operated extensive generation assets, including early adoption of nuclear power in Illinois.[19][3] The $32.7 billion stock-for-stock transaction integrated PECO's regulated delivery operations with Unicom's competitive generation portfolio, positioning Exelon to capitalize on post-deregulation opportunities in wholesale power markets amid the energy sector's shift from monopolistic structures.[18] Headquartered at Chicago's Chase Tower, the new entity initially managed about 5 million electric customers and 1.5 million gas customers, with a combined generating capacity exceeding 30,000 megawatts, predominantly nuclear and fossil fuel-based.[20] In the immediate post-merger phase, Exelon implemented a restructuring effective January 1, 2001, to segregate regulated transmission and distribution from merchant generation functions, complying with federal and state utility regulations.[21] Exelon Generation Company, LLC, established in 2000 as a subsidiary, assumed control of non-rate-regulated power plants, enabling focused investment in nuclear fleet reliability and efficiency upgrades during a period of market volatility.[22] This separation supported Exelon's early strategy of leveraging Pennsylvania's 1996 deregulation for competitive retail services while maintaining monopoly status in delivery infrastructure.[18]Major Mergers and Expansions
Exelon Corporation was formed on October 24, 2000, through the merger of PECO Energy Company and Unicom Corporation, the parent of Commonwealth Edison (ComEd).[23][3] The transaction, valued at approximately $9.77 billion, combined PECO's operations in Pennsylvania with ComEd's in Illinois, creating one of the largest U.S. electric utilities with over $12 billion in annual revenues and serving about 5 million customers across two major metropolitan areas.[24][23] This merger positioned Exelon for growth in a deregulated energy market, emphasizing transmission, distribution, and competitive generation services.[19] In 2011, Exelon announced its acquisition of Constellation Energy Group on April 28 for $7.9 billion in cash and stock, equivalent to $38.59 per share.[25] The deal closed on March 12, 2012, after regulatory approvals including divestitures of three fossil fuel plants mandated by the U.S. Department of Justice to preserve competition.[26][27] This expanded Exelon's generation portfolio to include Constellation's nuclear, renewable, and competitive energy assets, making the combined entity the largest U.S. power utility by capacity with over 32,000 megawatts and serving 7.7 million customers.[28] Exelon further grew through its $6.8 billion acquisition of Pepco Holdings Inc., announced on April 30, 2014, and completed on March 23, 2016, following multi-year regulatory reviews and conditions such as bill credits and grid investments.[29][30] The merger integrated Pepco's utilities—serving 2 million customers in Washington, D.C., Maryland, and Delaware—with Exelon's existing operations, enhancing geographic scale in the Mid-Atlantic region and adding regulated transmission and distribution infrastructure valued at billions in assets.[29] This transaction solidified Exelon's focus on regulated utility services amid the spin-off of its competitive generation business.[31]Spin-off of Generation Assets
In February 2021, Exelon Corporation announced its intention to separate its competitive energy businesses—encompassing power generation and retail energy supply—into a standalone publicly traded company, subsequently named Constellation Energy Corporation, to allow each entity to pursue distinct strategic priorities.[32] The separation aimed to enable Exelon to concentrate on its regulated utility operations, including electricity transmission and distribution, while Constellation would manage the generation portfolio, which included the largest fleet of nuclear power plants in the United States, along with hydroelectric, wind, solar, and natural gas assets totaling approximately 32,400 megawatts of capacity.[33] This move was positioned as a response to differing regulatory environments and market dynamics, with regulated utilities benefiting from stable returns and generation businesses exposed to competitive wholesale markets and clean energy transitions.[34] The transaction required approvals from multiple regulatory bodies, including the Federal Energy Regulatory Commission (FERC), the Nuclear Regulatory Commission (NRC), and the New York Public Service Commission (NYPSC), due to the interstate nature of energy markets and nuclear operations.[32] FERC authorized the spin-off in December 2021, confirming it would not adversely affect competition or rates, while the NRC approved the transfer of licenses for nuclear facilities.[35] The process involved a tax-free distribution to Exelon shareholders, structured as a pro-rata spin-off where eligible holders received one share of Constellation common stock for every three shares of Exelon stock owned as of the record date.[36] Exelon completed the separation on February 1, 2022, with Constellation shares beginning to trade on the Nasdaq under the ticker "CEG" the following day.[4] Post-spin-off, Constellation operated independently with a market capitalization exceeding $30 billion at launch and committed to an initial annual dividend of $0.55 per share, supported by its generation assets' cash flows.[33] Exelon, retaining its focus on utilities serving over 10 million customers across six states, reported streamlined operations without the volatility of merchant generation, though it faced ongoing capital needs for grid infrastructure.[4] The spin-off was deemed tax-free for U.S. federal income tax purposes for most shareholders, barring specific exceptions like excessive ownership concentrations.[36]Recent Strategic Shifts
Following the 2022 spin-off of its competitive generation assets to Constellation Energy Corporation, Exelon repositioned itself as a pure-play transmission and distribution (T&D) utility holding company, emphasizing regulated infrastructure investments to enhance grid reliability and support electrification trends.[37][38] This shift allowed Exelon to prioritize stable, rate-regulated operations across its subsidiaries—ComEd, PECO, BGE, Pepco, Delmarva Power, and Atlantic City Electric—serving approximately 10 million customers in Illinois, Pennsylvania, Maryland, Delaware, New Jersey, and the District of Columbia, without exposure to volatile wholesale power markets.[39] A core element of this strategy has been a $38 billion capital expenditure plan from 2024 through 2028, targeted at grid modernization to accommodate surging electricity demand from data centers, artificial intelligence infrastructure, electric vehicles, and renewable energy integration.[40][41] These investments include upgrading transmission lines, substations, and distribution networks to improve resilience against extreme weather and enable faster connections for large-load customers, with projected rate-base growth of 7.4% annually driving EBITDA expansion.[40] Exelon has secured regulatory approvals in multiple jurisdictions to recover these costs through rate cases, underscoring a focus on proactive infrastructure funding amid federal incentives like the Inflation Reduction Act.[42] In parallel, Exelon has advanced sustainability initiatives within its T&D operations, investing in methane leak detection and reduction technologies for natural gas distribution systems and electrifying fleet vehicles to lower Scope 1 and 2 greenhouse gas emissions.[43] The company reported progress in 2023 toward these goals, including enhanced transmission system reliability metrics, while maintaining affordability for customers during the energy transition through partnerships with stakeholders and cost-conscious planning.[44][45] Financially, Exelon has reaffirmed long-term earnings growth targets of 5-7% compounded annual EPS from 2024 to 2028, supported by disciplined capital allocation and a $2.5 billion at-the-market equity program initiated in May 2025 to optimize its balance sheet.[46][47] As of August 2025, executives indicated potential exploration of re-entering power generation development after a three-year hiatus post-spin-off, though no firm commitments have been announced, reflecting evolving opportunities in clean energy infrastructure.[48]Business Operations
Transmission and Distribution Infrastructure
Exelon's transmission and distribution infrastructure encompasses the assets of its six regulated utility subsidiaries—Atlantic City Electric (New Jersey), Baltimore Gas and Electric (BGE, Maryland), Commonwealth Edison (ComEd, Illinois), Delmarva Power (Delaware and Maryland), PECO Energy (Pennsylvania), and Pepco (District of Columbia and Maryland)—which collectively deliver electricity and natural gas across the Mid-Atlantic and Midwest.[9] These networks form part of the PJM Interconnection, a regional transmission organization overseeing grid operations in 13 states and the District of Columbia.[49] The electric transmission system includes approximately 11,000 miles of high-voltage lines, designed to transport bulk power over long distances at voltages typically ranging from 69 kV to 765 kV, ensuring reliability and integration with generation sources.[50] Distribution infrastructure extends this to end-users via over 153,000 miles of lower-voltage lines (generally 4 kV to 34.5 kV), supported by thousands of substations for voltage transformation and load balancing.[51] For instance, ComEd operates about 90,000 miles of power lines (combining transmission and distribution) and 1,300 substations across northern Illinois.[52] PECO maintains roughly 30,500 miles of electric lines, while BGE manages more than 25,000 circuit miles of distribution lines and nearly 1,300 miles of transmission.[53] Natural gas distribution, handled by subsidiaries like BGE, PECO, and Delmarva Power, includes thousands of miles of mains and service lines; for example, PECO oversees more than 13,400 miles of gas distribution infrastructure. These assets prioritize resilience against weather events and cyber threats, with ongoing investments totaling $7.6 billion in 2024 for upgrades such as advanced metering, undergrounding lines, and smart grid technologies to minimize outages and support growing electrification demands.[51] Cumulative planned capital expenditures of $38 billion from 2025 to 2028 further emphasize hardening transmission towers, replacing aging distribution conductors, and expanding capacity for data centers and renewables integration.[51]Service Territories and Customer Base

Grid Modernization and Investments
Exelon's operating subsidiaries have prioritized grid modernization through substantial capital investments aimed at enhancing reliability, resilience, and capacity to integrate distributed energy resources, electric vehicles, and emerging loads such as data centers. The company outlined a $38 billion capital expenditure plan for its regulated utilities from 2025 to 2028, marking a 10% increase over the prior four-year forecast, with funds allocated primarily to transmission and distribution upgrades, substation reinforcements, and advanced metering infrastructure to address aging assets and rising demand.[59][60] These efforts have yielded measurable improvements in system performance, including approximately a 40% enhancement in reliability indices such as the System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI) across service territories.[61] In 2024, Exelon invested $7.1 billion in grid-related projects, focusing on transmission expansions and hardening infrastructure against extreme weather events.[41] Subsidiaries like ComEd and PECO have driven specific initiatives, including ComEd's $50 million allocation from federal grants to pilot next-generation technologies for equitable clean energy deployment and grid orchestration.[62] Transmission investments have accelerated in response to hyperscale data center growth, with Exelon's interconnection queue doubling to 36 gigawatts since late 2024, prompting up to $15 billion in additional spending outside the base plan to build new lines and interconnect projects in PJM Interconnection markets.[63] Baltimore Gas and Electric (BGE), PECO, and others are incorporating smart grid elements, such as advanced sensors and automation, to reduce outage durations and support renewable penetration, aligning with Exelon's operational emissions reduction target of 50% by 2030 from a 2015 baseline.[64] Complementary programs include partnerships with startups via in-kind services and funding for scalable solutions in decarbonization and demand response, fostering innovation without direct ownership of generation assets.[65] Regulatory approvals for these expenditures, often recovered through rate cases, ensure alignment with public utility commissions' reliability mandates while minimizing cost burdens on customers.[66]Financial Performance
Revenue and Earnings Trends
Exelon's revenue has exhibited consistent growth since the 2022 spin-off of its competitive generation business to Constellation Energy, reflecting a focus on stable, regulated transmission and distribution operations across its utilities. Annual revenue increased from $17.938 billion in 2021 to $23.028 billion in 2024, a compound annual growth rate of approximately 8.7%, primarily driven by rate base expansions, customer growth, and investments in grid infrastructure.[67][68] Net income followed a similar upward trajectory, rising from $1.706 billion in 2021 to $2.460 billion in 2024, supported by operational efficiencies and favorable regulatory outcomes despite weather variability and higher operating costs.[67][69] This growth outpaced the broader electric utilities sector average, with earnings expanding at an average annual rate of about 8.2% over the period.[70]| Year | Revenue ($B) | YoY Growth (%) | Net Income ($B) | YoY Growth (%) |
