Duquesne Light Co rate plans
3 residential plans are currently open to new customers. None of them price by hour, so shifting when you use power won’t change your bill here.
What does Duquesne Light cost at a normal month’s usage?
A household using 1,000 kWh a month pays about $2,553 a year on the cheapest of the 3 plans we can price here — Residential Service Add-On Heat Pump — and $2,848 on the priciest. Same house, same wires.
| A month of | Cheapest, a year | On which plan | Priciest |
|---|---|---|---|
| 500 kWh | $1,355 | Residential Service Add-On Heat Pump | $1,502 |
| 1,000 kWh | $2,553 | Residential Service Add-On Heat Pump | $2,848 |
| 2,000 kWh | $4,951 | Residential Service Add-On Heat Pump | $5,541 |
The same plan is cheapest at every level of use here, so the answer does not turn on how much you use. Estimates from the filed tariff, priced hour by hour on a household with central air — not a quote.
How much does the plan you pick actually matter here?
Run the same three-bedroom house with central air through every plan Duquesne Light Co files, and the bill lands anywhere between $2,044 and $2,276 a year. That $232 spread is not a difference in electricity — it is the same kilowatt-hours, from the same wires, priced under different rules. Nobody sends you a letter when you are on the wrong side of it.
The plan most households land on by default, Residential Service, comes to about $2,276. The cheapest option here, Residential Service Add-On Heat Pump, comes to $2,044 — a gap of about $232 a year for a household that never changed a single habit. Whether you can actually capture that depends on when you use power, which is what the calculator below is for.
None of these 3 plans price by the hour, so when you use electricity here makes no difference to what you pay — only how much. That narrows your options to two levers: use less, or pick the plan whose fixed charge and tier structure suit your size of household.
How Duquesne Light compares across Pennsylvania
Run the same three-bedroom house with central air through its default plan at each of the 3 Pennsylvania utilities we cover, and Duquesne Light is the dearest of the lot at about $2,276 a year; the state median is $2,204. The cheapest, PPL Electric Utilities, charges $1,888 for identical use — a gap set by the address, not by anything either household did.
The other two households tell the same story in different sizes: a small apartment pays about $1,247 here against a state median of $1,201, and the same house with an electric car charging overnight about $3,095 against $3,003. Effective rate, fixed charge included, is 24.1¢ per kilowatt-hour for the family home.
Inside Duquesne Light itself, the gap between its cheapest and dearest plan for that house is $232 a year — less than the $388 between Pennsylvania's cheapest and dearest utilities. Here the address decides most of the bill; the plan decides the rest.

Same usage, different plan
$194a year
That is the gap between the cheapest plan you could be on — Residential Service Add-On Heat Pump — and the priciest. Not by using less power. By being billed differently for the same power.
| Plan | Per year | Vs best |
|---|---|---|
| Residential Service Add-On Heat PumpThe hour never matters here — only the season. Rates peak May–October. | $1,490 | — |
| Residential Service HeatingThe hour never matters here — only the season. Rates peak May–October. | $1,580 | +$90 |
| Residential ServiceOne rate, every hour of the year. | $1,684 | +$194 |
An estimate, not a quote. Supply charges move month to month, and your real usage pattern is not exactly this one. What it does show reliably is the gap between plans — both are priced off the same assumptions.
