Revenue Model & Pricing
Exelon is a transmission and distribution (T&D) utility. It does not generate electricity. Its utilities buy power and gas for default-service customers and pass those commodity costs through to bills without markup, then earn money on the delivery network itself. State commissions (the Illinois Commerce Commission, Pennsylvania PUC, Maryland PSC, Delaware PSC, New Jersey BPU and D.C. PSC) set distribution rates, and FERC sets transmission rates through annual formula rates. In each case Exelon recovers operating costs and earns an authorized return on equity on its rate base, the depreciated value of its poles, wires, substations, meters and gas mains. More approved investment means more rate base and more earnings, which is why the capital plan drives the investment case.

Growth Strategy
Growth comes almost entirely from investing in regulated assets. The 2026 to 2029 plan shifts money toward high-voltage transmission, which earns FERC formula rates with annual true-ups, while some PECO and BGE distribution projects were deferred to ease bill pressure. Exelon is also pushing for utilities to be allowed to own generation or storage again in states facing PJM supply shortfalls, and has filed battery storage proposals such as ACE's in New Jersey. Large-load interconnections for data centers in northern Illinois and the Mid-Atlantic add both transmission spending and new revenue that can spread fixed costs.
How Exelon Makes Money: FAQ
How does Exelon's fully regulated utility business model generate revenue?
Exelon generates revenue through state-regulated utility rate structures approved by public utility commissions (PUCs) in Illinois, Pennsylvania, Maryland, Delaware, New Jersey, and Washington, D.C., as well as formula rates approved by the Federal Energy Regulatory Commission (FERC) for wholesale transmission lines. Revenue is derived from delivering electricity and gas to residential, commercial, and industrial customers.
What is the 'Rate Base' and how does it determine Exelon's net earnings?
The Rate Base represents the depreciated book value of Exelon's capital investments in utility infrastructure (substations, smart meters, wires, transformers, and gas pipes). Regulators allow Exelon to earn an authorized Return on Equity (ROE), typically between 9.0% and 10.0%, on the equity portion of this rate base, ensuring earnings grow in tandem with capital grid investments.
Why does Exelon carry no direct commodity price risk for electricity or natural gas generation?
As a pure transmission and distribution utility post-spinoff, Exelon does not generate power. Instead, it procures wholesale electricity and natural gas on competitive wholesale markets on behalf of default customers and passes the exact commodity cost through to ratepayers on a dollar-for-dollar basis with zero profit markup, completely insulating corporate earnings from commodity price spikes.
What are the differences between distribution rates and transmission rates in Exelon's business?
Distribution rates cover local low-voltage delivery lines and substations, regulated by state public service commissions via periodic rate cases or multi-year performance plans. Transmission rates cover high-voltage bulk electricity transport lines, regulated by FERC under formula rate mechanisms that provide annual true-ups based on actual incurred capital and operating costs.
How do Multi-Year Rate Plans (MYRP) benefit Exelon's long-term capital planning?
Multi-Year Rate Plans, utilized in jurisdictions like Illinois (ComEd) and the District of Columbia (Pepco), establish pre-approved multi-year capital investment programs and annual rate adjustments tied to performance metrics, providing predictable multi-year revenue visibility and reducing regulatory lag.
How does Exelon invest capital to harden the electrical grid against climate change?
Exelon invests in smart automated switchgear, elevated flood-proof substations, composite utility poles, advanced distribution management systems (ADMS), and undergrounding critical distribution lines, drastically reducing storm outage durations and improving System Average Interruption Duration Index (SAIDI) scores.
How do smart grid meters and automated digital sensors drive utility operating efficiency?
Exelon has deployed over 10 million smart electric and gas meters across its six operating utilities. Smart meters allow automated remote meter reading, immediate fault location detection, dynamic time-of-use pricing enablement, and automated service connections, significantly lowering field dispatch operating expenses.
What customer programs does Exelon offer to support low-income affordability and energy efficiency?
Exelon utilities administer extensive energy assistance funds, flexible payment arrangements, weatherization assistance, and rebate programs for energy-efficient appliances, funded in partnership with state public benefit programs to ensure vulnerable customers maintain reliable utility access.
How does Exelon make money?
As of 2022, Exelon operates strictly as a regulated "Transmission and Distribution" (T&D) utility. They do not own the massive power plants anymore. They make highly predictable, state-guaranteed profits simply by maintaining the millions of miles of electrical wires and gas pipes that deliver power to homes and businesses.
