All DC utilities

What Pepco does (and does not) do

Both DC (since 2001) and Maryland (since 2000) split electric supply from delivery. Pepco keeps the wires, meters and grid; the energy itself can come from Pepco's default service auction or from a competitive supplier you chose.

Delivery (always Pepco)

Poles, wires, substations, transformers, smart meters and the field crews that restore power after a storm. The Pepco distribution charge applies on every bill, regardless of who supplies the energy.

Default supply (SOS)

If you do not shop, Pepco buys power for you through competitive wholesale auctions in PJM and bills the clearing price as SOS. DC and Maryland each run their own SOS auction with separate rates.

Outage response

Whether you shop or not, Pepco is the only company you call for outages, downed lines, voltage problems or meter issues. The same 24/7 line, 1-877-737-2662, covers DC and both Maryland counties.

About Potomac Electric Power Company

Pepco was incorporated on April 28, 1896 as the Potomac Electric Power Company, eventually consolidating the small generating stations that lit the federal city. For more than a century it was a vertically integrated utility owning generation, transmission and distribution. The 1999 Maryland Electric Customer Choice and Competition Act and the parallel District of Columbia restructuring forced Pepco to divest its power plants between 2000 and 2002. Since then, Pepco has been a wires-only EDC.

In 2002 Pepco merged with Conectiv to form Pepco Holdings Inc. (PHI), the parent of Pepco, Delmarva Power and Atlantic City Electric. Thirteen years later, on March 23, 2016, after a two-year regulatory fight in DC, Exelon completed its $6.8 billion acquisition of PHI. Pepco kept its brand and tariff identity; only the ultimate parent changed.

Pepco is a single legal entity (Potomac Electric Power Company) regulated by two state-level commissions: the District of Columbia Public Service Commission (DC PSC) for the ~300,000 DC customers, and the Maryland Public Service Commission (MD PSC) for the ~600,000 customers in Prince George's and Montgomery counties. Wholesale transmission rates are set by the FERC, and the bulk grid is operated by PJM Interconnection.

Anatomy of a Pepco bill

A Pepco residential bill is split into two halves: supply (the energy itself, shoppable) and delivery (Pepco charges, non-shoppable). Knowing which line is which is the first step to lowering your bill.

Line item What it pays for Shoppable?
Generation (SOS or supplier rate) The energy itself, in cents per kWh Yes
Transmission service PJM high-voltage grid cost, set by FERC No
Distribution charge Pepco poles, wires and meters No
Customer charge Fixed monthly fee for billing & meter reading No
Riders & surcharges EmPower MD, DC Sustainable Energy Utility, universal service, franchise fees No
Taxes DC right-of-way fee, MD environmental surcharge, local sales taxes No

Reading tip

Only the generation line is competitive. If a third-party supplier offer beats Pepco's current SOS price, the supply portion of your bill drops; the delivery, transmission and rider lines stay exactly the same. Look for the box labeled "Price to Compare" on your Pepco bill before signing anything with a supplier.

DC Standard Offer Service (SOS) and shopping

The DC SOS is the per-kWh price Pepco charges DC customers for default supply if you have not picked a competitive supplier. It is the benchmark every shopping offer at energychoice.dc.gov is compared against.

DC average residential rate

What it means for you

Compare any supplier offer to the SOS generation rate printed on your Pepco bill (not to the all-in average). A deal below the current SOS lowers the supply portion of your bill on day one. Many supplier offers reset after a 3 to 12 month introductory period, so always read the renewal clause and the cancellation fee before signing.

Maryland Standard Offer Service (SOS) and shopping

Pepco Maryland customers in Prince George's and Montgomery counties have had retail choice since the Maryland Electric Customer Choice and Competition Act of 1999. The official shopping site is mdelectricchoice.com.

What it means for you

The MD PSC publishes the Pepco Type I residential SOS rate twice a year; the figure printed on page 2 of your Pepco bill, labeled "Price to Compare," is always the most current one. Compare each supplier offer at mdelectricchoice.com to that number, not to the all-in average above.

If you cannot pay your bill

Pepco participates in DC and Maryland assistance programs. Apply before a disconnection notice; once enrolled, the DC winter moratorium (Nov 1 to Mar 31) and Maryland's cold-weather rule protect most residential customers.

DC LIHEAP & Utility Discount Program

Federal LIHEAP grants and a Pepco bill credit administered by the DC Department of Energy and Environment (DOEE). Open year-round; winter window opens November.

Maryland MEAP & EUSP

The Maryland Energy Assistance Program (MEAP) and Electric Universal Service Program (EUSP), run by the MD Office of Home Energy Programs (OHEP), pay part of the bill for income-qualified households.

Good Neighbor Energy Fund

Hardship grant funded by Pepco customer donations and corporate matching, administered by The Salvation Army. Available to DC and MD customers who do not qualify for LIHEAP.

Can I switch electricity suppliers in Pepco territory?

Yes, on both sides of the Pepco footprint. Maryland opened retail competition in 2000 under the 1999 Electric Customer Choice and Competition Act. The District of Columbia followed in 2001 under the Retail Electric Competition and Consumer Protection Act of 1999. Pepco still owns the wires; only the supply line on your bill changes.

Each jurisdiction runs an official shopping site:

Every offer shown on those marketplaces must disclose the price, contract term, renewal terms and any cancellation fee. Compare each offer against the SOS generation rate printed on your Pepco bill. A switch typically takes 1 to 2 billing cycles, and Pepco does not charge any fee to switch.

Frequently asked questions

Who owns Pepco?
Pepco is a subsidiary of Exelon Corporation (NASDAQ: EXC), the Chicago-headquartered utility holding company. Exelon acquired Pepco Holdings Inc. on March 23, 2016. The legal entity is still Potomac Electric Power Company; only the parent changed. Other Exelon utilities include BGE, Delmarva Power, Atlantic City Electric, ComEd and PECO.
Is Pepco the same company as Exelon?
No, but they are related. Exelon is the publicly traded parent (NASDAQ: EXC). Pepco is its DC/Maryland wires-only subsidiary, regulated locally by the DC PSC and MD PSC. Pepco's tariffs, rates and service standards are set by those two commissions, not by Exelon's board.
Can I shop for a cheaper electricity supplier in DC?
Yes. DC opened retail electric competition in 2001. You can stay on Pepco's Standard Offer Service or pick a licensed competitive supplier on energychoice.dc.gov. Pepco continues to deliver the power and respond to outages no matter which supplier you choose.
Can I shop for a cheaper electricity supplier in Maryland?
Yes. Maryland passed the Electric Customer Choice and Competition Act in 1999 and retail competition opened in 2000. You can stay on Pepco's Type I residential SOS or pick a supplier on mdelectricchoice.com. Delivery still comes from Pepco.
Who do I call for a power outage or downed line?
Call Pepco 24/7 at 1-877-737-2662 (1-877-PEPCO-62), or text OUT to 48710. If a wire is on the ground or anyone is hurt, dial 911 first, then Pepco. Do not approach a downed line; assume it is energized.
Does Pepco deliver natural gas?
No. Pepco is electricity only. Natural gas in DC, Prince George's and Montgomery counties is distributed by Washington Gas (a WGL Holdings / AltaGas subsidiary). Smell gas? Leave the building and call Washington Gas at 1-844-WASHGAS (1-844-927-4427) from a safe distance.
Where are Pepco's walk-in customer service offices?
Pepco has consolidated most in-person service since the Exelon merger. The corporate building at 701 9th Street NW in Washington is not a public bill-pay counter. For cash payments, use an authorized agent: CheckFreePay at most CVS pharmacies and Walmart MoneyCenters accepts Pepco payments at no charge with the bill stub. For account questions, the fastest path is the phone line or the My Account portal at pepco.com.
Is help available if I cannot pay my Pepco bill?
Yes. DC residents can apply for LIHEAP and the Utility Discount Program through the DC Department of Energy and Environment (DOEE). Maryland residents apply through the MD Office of Home Energy Programs (OHEP) for MEAP and EUSP. Both DC and MD Pepco customers can also request a Good Neighbor Energy Fund grant through The Salvation Army. The DC winter moratorium runs Nov 1 to Mar 31, and Maryland has a cold-weather rule limiting disconnections from Nov 1 to Mar 31.
