Quick answers
Common questions DC + adjacent MD households ask about Pepco offices.
Pepco's franchise covers DC + the inner MD suburbs (Prince George's and Montgomery counties). The same Exelon subsidiary handles ~286K DC customers and ~278K MD customers. The 20772 office in Upper Marlboro (PG County) and the 20850 office in Rockville (Montgomery County) are MD-side, but DC residents — especially those in NE Wards 5 + 7 or the upper NW — sometimes find the MD office is the closest drivable option.
Usually no. Almost everything (start service, stop service, set up auto-pay, request a payment plan) can be done by phone or online: 1-877-737-2662 or pepco.com. Walk-in offices are most useful for cash payments and Utility Discount Program (LIHEAP) paperwork.
Always Pepco's 24/7 outage line: 1-877-737-2662. Or text OUT to 48710 to report. Never call a competitive supplier for an outage — they have no field crews. The office may itself be in the outage and counter staff cannot dispatch crews.
Leave the building immediately. Once outside, call Washington Gas 24/7: 1-844-WAS-GASS (1-844-927-4277). Pepco does not deliver gas in DC. Service at the meter is free.
Yes. DC opened residential retail choice in 2001. Pepco remains your distribution utility (no choice there), but you can pick a DC PSC-licensed Competitive Energy Supplier (CES) for the supply portion of your bill, or stay on Pepco's auction-priced Standard Offer Service (SOS) by default.
The DC Public Service Commission (DCPSC), a 3-member body, regulates Pepco's delivery rates, licenses Competitive Energy Suppliers and runs the residential energy choice portal. The Office of the People's Counsel (OPC) represents DC ratepayers in rate cases.
