About Exelon

Exelon Corporation is one of the largest regulated utility companies in the United States. The Chicago-based company delivers electricity and natural gas through six major regulated utilities: Commonwealth Edison (ComEd), Baltimore Gas and Electric (BGE), PECO Energy Company, Pepco, Delmarva Power, and Atlantic City Electric. Together, these utilities serve almost 11 million customers across major metropolitan areas including Chicago, Philadelphia, Baltimore, and Washington, D.C. Exelon focuses primarily on electricity and natural-gas transmission and distribution rather than competitive power generation.

Exelon has evolved considerably in recent years. Following the 2022 separation of Constellation Energy, Exelon became a more focused regulated transmission and distribution utility company. Its operating companies maintain electric grids, gas systems, substations, transmission assets, smart-meter infrastructure, customer-service platforms, energy-efficiency programs, and major grid-modernization projects across Illinois, Pennsylvania, Maryland, Delaware, New Jersey, and the District of Columbia.

As of December 31, 2025, Exelon reported 20,571 employees, while its current corporate materials round the figure to more than 20,000 employees. The company reported approximately $24.3 billion in utility operating revenue for 2025 and plans about $41.3 billion of capital investment from 2026 through 2029 to strengthen and modernize its infrastructure. Exelon is publicly traded on Nasdaq under ticker EXC, and its current President and CEO is Calvin Butler.

Exelon Products & Services

Electric Distribution

Exelon’s utilities deliver electricity to residential, commercial, institutional, and industrial customers through extensive local distribution networks. These systems include substations, transformers, power lines, underground cables, meters, and related grid infrastructure.

Electric Transmission

Exelon operating companies own and manage transmission infrastructure that moves large quantities of electricity across regional power systems. Transmission investment is an important component of Exelon’s current multi-billion-dollar capital plan.

Natural Gas Distribution

BGE, PECO, and Delmarva Power provide regulated natural-gas distribution in portions of their service territories. Services include gas delivery, infrastructure maintenance, meter management, leak response, and system upgrades.

ComEd

Commonwealth Edison provides electric utility service across northern Illinois, including Chicago. ComEd is one of Exelon’s largest regulated operating companies and is responsible for electricity delivery, outage restoration, customer accounts, and grid modernization in its territory.

BGE

Baltimore Gas and Electric provides both electricity and natural gas service across central Maryland, including the Baltimore region. It operates as a regulated Exelon utility with dedicated customer-service and emergency-response operations.

PECO

PECO provides electricity and natural gas services in southeastern Pennsylvania, including the Philadelphia region. Its services include account management, power and gas delivery, outage restoration, energy-efficiency programs, and infrastructure maintenance.

Pepco

Pepco provides electric utility service in Washington, D.C. and parts of Maryland. It is part of Pepco Holdings and operates within Exelon’s regulated utility portfolio.

Delmarva Power

Delmarva Power provides electric and natural-gas service in Delaware and electric service in portions of Maryland. The utility manages customer accounts, energy delivery, outage response, and infrastructure investments.

Atlantic City Electric

Atlantic City Electric supplies electricity in southern New Jersey. Customer service, billing, outages, interconnections, and local distribution are handled directly through Atlantic City Electric rather than Exelon Corporate.

Grid Modernization

Exelon invests in smart-grid technology, automated distribution equipment, advanced metering, transmission upgrades, storm resilience, and other infrastructure designed to reduce outage frequency and improve restoration times.

Energy Efficiency Programs

Exelon utilities administer energy-efficiency programs that can help eligible residential and commercial customers reduce electricity or gas consumption. Programs vary according to utility, regulator, customer class, and jurisdiction.

Outage Restoration

Each Exelon utility operates outage-management and emergency-restoration systems. Customers experiencing service interruptions should report the outage directly to their local utility rather than calling Exelon Corporate.

Utility Customer Accounts

Billing, payment arrangements, service starts and stops, meter questions, rate-plan matters, and account disputes are managed by the applicable utility company, not through a single Exelon-wide retail system.

How to Reach a Real Person at Exelon

For an Exelon corporate matter, call 800-483-3220 and explain the department you need, such as corporate administration, investor relations, legal, supplier relations, or another enterprise function. For investor inquiries, calling 779-231-0017 directly can be more efficient. Journalists should use the dedicated media line at 312-394-7417 rather than the general corporate number.

For a residential or business utility issue, do not start with Exelon Corporate unless the local utility has already failed to resolve the matter. Check the company name on the utility bill and contact ComEd, BGE, PECO, Pepco, Delmarva Power, or Atlantic City Electric directly. Have your account number, service address, phone number, disputed bill, outage details, meter information, and previous case numbers ready.

For serious utility complaints, keep a record of every representative contacted, the dates of each conversation, promised resolutions, billing statements, photographs where applicable, and any regulatory case numbers. Because utility regulation is state-specific, Exelon Corporate cannot replace the formal complaint procedures of the customer’s operating utility and state public utility commission.

How to File a Complaint Against Exelon

Complaints involving Exelon can include billing, service reliability, outages, meter disputes, account problems, infrastructure, customer service, gas or electric safety, investor matters, ethics, supplier issues, or corporate conduct. Before escalating, gather the utility account number, service address, bills, payment records, outage dates, photographs, previous complaint numbers, and copies of written correspondence.

Step 1: Contact Customer Service

For a utility-service complaint, contact the operating utility shown on your bill first. Explain the issue clearly and ask the representative to create a complaint or service case. Record the representative’s name, date, time, and case number, and keep copies of bills or other documents that support your position.

Step 2: Contact the Relevant Department

If ordinary Customer Service cannot resolve the issue, ask for the department responsible for the specific matter, such as billing, metering, payment arrangements, outages, new service, gas safety, electric delivery, vegetation management, or claims. Specialized departments generally have greater authority and technical information than first-line support.

Step 3: Request Supervisor or Management Review

Ask for a supervisor when the issue remains unresolved after the appropriate department has reviewed it. Provide a short chronological summary showing what happened, whom you contacted, what Exelon’s utility promised, and what remains disputed. Request a written explanation when the complaint involves a significant billing or service decision.

Step 4: Use the Company’s Written Complaint Channel

Submit a written complaint through the operating utility’s official website, customer-contact form, or written correspondence channel. Written complaints create a stronger record than repeated phone conversations because they establish dates, disputed amounts, requested corrections, and supporting evidence.

Step 5: Contact Corporate Headquarters

For a serious unresolved parent-company matter, contact Exelon Corporation, 10 S. Dearborn Street, 54th Floor, Chicago, IL 60603, or call 800-483-3220. Corporate headquarters is more appropriate for enterprise-level concerns than ordinary utility billing complaints, which should normally remain with the operating company.

Step 6: Use the Specialized Complaint or Dispute Department

Ethics, compliance, supplier, investor, legal, and utility-specific disputes should be directed to the specialized channel responsible for the issue. Investor matters can use Investor Relations, while ethical or corporate-conduct concerns should follow Exelon’s ethics and compliance process. Utility claims may require a separate claims department.

Step 7: File With the Appropriate Regulator

Unresolved regulated-utility complaints can generally be escalated to the public utility commission or public service commission governing the customer’s state or district. For example, ComEd customers fall under Illinois utility regulation, BGE customers under Maryland regulation, PECO customers under Pennsylvania regulation, and Pepco customers under Maryland or District of Columbia oversight.

Step 8: Use Consumer Protection or Financial Dispute Options

Depending on the issue, customers may also contact their state Attorney General, consumer-protection agency, payment provider, or another relevant authority. These options can be useful when the dispute involves billing practices, unauthorized transactions, misleading communications, or a complaint that falls outside the utility commission’s primary jurisdiction.

Step 9: Consider Formal Legal or Arbitration Procedures

If all internal and regulatory avenues fail, review the applicable utility tariff, service agreement, state law, and any dispute-resolution provisions before considering legal action. Significant property-damage claims, contractual disputes, or complex regulatory matters may justify consultation with a qualified attorney. Preserve the complete complaint history, bills, correspondence, photographs, and regulatory decisions before proceeding.
