Of the 4 Maryland utilities we track, Delmarva Power's Standard Offer Service is the lowest — the range runs from 12.35¢ (Delmarva Power) to 14.609¢ (Baltimore Gas & Electric (BGE)). Compare all Maryland rates →

What it means: a Delmarva Power customer on a 17¢/kWh third-party supplier rate pays about $480 more per year than the Standard Offer Service (12.35¢), based on ~860 kWh/month. The audit below checks your actual rate.

The worth-it line: for a switch to save at least $10/month at ~750 kWh, a supplier offer must be a fixed rate below 11.02¢/kWh — with no monthly fee and no cancellation fee. Offers between 11.02¢ and 12.35¢ technically "beat" the Standard Offer Service but save too little to justify contract risk. The full math, all utilities →

Is Delmarva Power a monopoly? Can you switch?

For delivery, yes — it's a monopoly. Delmarva Power is the only company that runs the poles and wires to homes in its territory, so you can't pick a different company to deliver your power. That part is a regulated monopoly: Delmarva Power, owned by Exelon (Pepco Holdings), can only charge what the MD PSC approves in a rate case.

The electricity itself, though, is open to competition. You can buy your supply from a third-party supplier, or do nothing and stay on Delmarva Power's default rate — the Standard Offer Service the MD PSC oversees. Switching suppliers doesn't change who delivers your power or who you call during an outage; it only changes the supply line on your bill. And if a supplier is charging more than the Standard Offer Service, you can drop it and return to that regulated rate, usually within one or two billing cycles — no fee to the utility.

How often does Delmarva Power's power go out?

Federal reliability data, reported by the utility to the U.S. government. SAIDI is the average total time a customer is without power in a year; SAIFI is the average number of outages.

For Delmarva Power, major storms drove roughly 29% of 2024's total outage time — the gap between the two numbers above is weather the utility couldn't fully control.

On normal-day reliability, Delmarva Power is the 2nd-most reliable of the 4 Maryland utilities we track — the range runs from 46 min (Pepco (Maryland)) to 2 hr 39 min (Potomac Edison) of typical-day outage time per year.

How often does Delmarva Power disconnect customers for nonpayment?

Utilities report this to the federal government. It counts residential service disconnected for unpaid bills. A high rate isn't proof of wrongdoing — it's shaped by local poverty, climate, and how strong a state's shutoff-protection rules are, as much as by the utility itself.

That's the highest disconnection rate of the 4 Maryland utilities we track — the range runs from 2.1 per 100 (Potomac Edison) to 4.1 per 100 (Delmarva Power).

Counts disconnection events — one household can be shut off more than once. From Delmarva Power's own filings to the U.S. EIA (Form EIA-112, Residential Utility Disconnections Survey), first collected for 2024. eia.gov →

Where your bill money goes: how Delmarva Power earns its profit

Because Delmarva Power is a regulated monopoly, its profit isn't set by competing for customers — it's set by regulators. The MD PSC authorizes a target return on equity (around 9.5% to 10.5% for U.S. electric utilities) on the money it sinks into poles, wires, substations, and meters. It's a target, not a guarantee — a utility can earn above or below it — but a low-risk regulated monopoly reliably lands close. You pay that return back, plus the investment itself, through the delivery charge on every bill.

Delmarva Power is owned by Exelon. In 2024, Exelon reported about $2.5 billion in net income — its profit across all of the utilities it owns, not Delmarva Power alone. Source: Exelon's annual report (SEC Form 10-K, fiscal year 2024). SEC EDGAR →

That authorized return is set by regulators on the utility's investment — independently of how reliable the service is or how many customers are disconnected, the two measures above.
