What the U.S. government data says about Potomac Edison
- Commercial customers32,5082025, EIA Form EIA-861

In 2025, 72% of the commercial kWh delivered by Potomac Edison went to customers buying energy from a competitive supplier, and 28% stayed on the utility's default service. By customer count it is 32%, because the businesses that shop tend to be the larger ones.
Potomac Edison’s delivery charges averaged 4.54¢ per kWh across its 10,532 delivery-only commercial customers: the part of the bill no supplier can change. It is an average over customers of every size. Large customers pay far less per kWh than small ones, so your own delivery charge per kWh will differ; the average customer here used about 12,129 kWh a month.
Potomac Edison customers went without power for an average of 174 minutes in 2025, excluding major storms, with about 1.05 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes.
EIA records Potomac Edison serving customers in 7 Maryland counties: Allegany, Carroll, Frederick, Garrett, Howard, Montgomery, Washington. A county can be shared between utilities, so this does not tell you who serves a given address.

Cities and areas in this territory
Territory boundaries do not follow city limits. Two addresses on the same street can sit in different territories, which is why we confirm the Account number rather than inferring eligibility from the city or the ZIP code. Inferring from location is the most common way a commercial account is told it can do something it cannot.

Which lever moves which charge
This is the question a utility page exists to answer. If you change something at the meter, which line on the bill actually moves — and which one does not move no matter what you do?
Schematic shapes, not Potomac Edison's actual rates — those come from the filed tariff. The point is the behaviour: two of these four respond to something you control, and a supplier changes none of them.
What sits inside the delivery charge from Potomac Edison
Delivery is not one number. On a commercial account it is typically assembled from several components, each set by the filed tariff and each behaving differently as your usage changes:
- A fixed customer or meter charge, which does not move with consumption at all.
- A volumetric distribution charge per kWh, which scales with how much you use.
- A demand charge per kW where the account is demand-metered, which scales with how hard you draw rather than how much you use — and which is where a low load factor account gets hurt.
- Riders and surcharges, adjusted periodically through regulatory filings, covering items such as transmission cost recovery, energy efficiency programs and storm or system restoration costs.
None of these changes when you change supplier. Understanding the mix matters because it determines which action actually moves your bill: reducing consumption attacks the volumetric component, reducing peak draw attacks the demand component, and neither one touches the fixed charge.
The other territories in Maryland
Boundaries do not follow city limits. If you are not certain which of these serves your address, confirm the Account number printed on the bill rather than inferring it from the city.
This page does not list Potomac Edison's rate schedules, demand thresholds or ratchet terms. Those come from the filed tariff, and we publish them only after reading the filing, so none appear here yet. Your schedule code is printed on the bill, and it is the first thing to look up.
What to pull off a Potomac Edison bill before any conversation
- Account number — the identifier that determines territory and eligibility
- Rate schedule code as printed on the bill
- 12 months of kWh, and peak kW if the account is demand-metered
- The delivery and supply sections, kept separate
- Current supplier and contract expiry, if any
