Pittsburgh households pay 13.75 cents per kilowatt-hour for default electricity supply. Erie households pay 11.747 cents. That means Pittsburgh, the larger city with the more developed economy, actually pays 17% more for electricity than Erie.
The gap is not intuitive. Larger markets often have lower costs due to scale. But Pennsylvania's utility territories do not follow population density, and electricity rates reflect procurement history, not city size.
The rate gap by the numbers
Both cities operate under Pennsylvania's deregulated electricity market. Customers who never choose a supplier pay their utility's default rate, called the Price to Compare (PTC). Here is how that benchmark stacks up:
| Metric | Pittsburgh (Duquesne Light) | Erie (Penelec) |
|---|---|---|
| Current PTC (through May 31) | 13.75¢/kWh | 11.747¢/kWh |
| June 2026 PTC | 14.14¢/kWh | 13.142¢/kWh |
| Increase | +2.8% | +11.9% |
| Residential customers | ~600,000 | ~590,000 |
At average Pennsylvania household usage of 850 kWh per month, the supply portion of your bill looks like this:
- Pittsburgh (Duquesne Light): $116.88 per month
- Erie (Penelec): $99.85 per month
- Difference: $17.03 per month, or roughly $204 per year
That annual gap is real money, and it runs opposite to what many expect. But the direction flips in June: Penelec's 11.9% increase will narrow the gap considerably.

Why Duquesne Light and Penelec rates differ
Both utilities purchase capacity and energy through PJM Interconnection, the regional grid operator that serves 65 million people across 13 states. Both are subject to the same wholesale market dynamics, including the 833% capacity auction price spike that has driven rates higher across Pennsylvania since 2024.
Yet their default rates diverge — and not in the direction you might expect. Several factors explain why Pittsburgh pays more:
Corporate structure and ownership. Duquesne Light is an independent utility, not part of a multi-state holding company. Penelec is part of FirstEnergy, a large holding company that also operates Met-Ed, Penn Power, and West Penn Power in Pennsylvania. Different corporate structures create different cost allocations and procurement approaches.
Service territory characteristics. Duquesne Light serves a compact, urban territory centered on Pittsburgh. Penelec serves a vast, largely rural territory across north-central and northwestern Pennsylvania, including Erie. Counterintuitively, serving a dense urban area does not always translate to lower rates — infrastructure age, peak demand patterns, and transmission costs all play roles.
Procurement timing. When a utility locked in wholesale power contracts matters enormously. Penelec's current rates reflect procurement decisions made at different times than Duquesne Light's. The June rate changes show this dynamic clearly: Penelec's 11.9% jump suggests their earlier contracts are rolling off into today's higher wholesale prices.
Rate case history. Pennsylvania utilities file rate cases with the Public Utility Commission at different intervals. The timing of these filings, and the specific cost allocations approved, create differences that persist between rate case cycles.
The result is that two western Pennsylvania customers using the same amount of electricity can pay meaningfully different rates based on which utility territory they happen to live in.

How usage patterns differ between the cities
Rate is only half the equation. Your bill equals rate times usage. Pittsburgh and Erie households use electricity differently.
Climate. Erie sits on Lake Erie and experiences significant lake-effect weather. Winters are harsh, with heavy snowfall and cold temperatures. Pittsburgh, about 120 miles south, has milder winters and less precipitation. Both cities have warm, humid summers. The climate difference affects heating costs for households using electric heat, though most western Pennsylvania homes heat with natural gas.
Housing stock. Pittsburgh has a diverse mix of housing: dense rowhouses and apartments in the city, older suburban homes, and newer construction in exurban areas. Erie's housing stock is generally smaller-scale, with more modest single-family homes and fewer large suburban developments. Housing age and size both affect electricity consumption.
Economic factors. Pittsburgh's economy has diversified into healthcare, education, and technology. Erie's economy is more manufacturing-focused. These differences affect commercial electricity demand more than residential, but the overall load characteristics of each utility territory influence how costs are allocated.
The practical implication: an Erie household paying the lower rate might still have a higher total bill if they use more electricity for heating or cooling. And a Pittsburgh household in an energy-efficient home might pay less despite the higher rate.
Average usage figures (around 850 kWh per month statewide) are just that, averages. Your actual bill depends on your actual usage.
Supplier competition by city
Pennsylvania's deregulated market means you can choose your electricity supplier regardless of which utility serves you. Both Pittsburgh and Erie have active competitive markets:
| Metric | Pittsburgh (Duquesne Light) | Erie (Penelec) |
|---|---|---|
| Active supplier plans | 107 | 95 |
| Number of suppliers | 54 | 49 |
| Cheapest available rate | 10.79¢/kWh | 10.49¢/kWh |
Pittsburgh's market is slightly more developed, with more plans available. Interestingly, the cheapest available rates are similar — Erie's cheapest plan is only 0.30¢ lower than Pittsburgh's cheapest. The competitive market partially levels the playing field that utility default rates tilt.

Which city's customers benefit more from switching
Here is the math that matters: how much can you save by switching from the default rate to the cheapest available plan?
Pittsburgh (Duquesne Light):
- Default rate: 13.75¢/kWh
- Cheapest available: 10.79¢/kWh
- Savings: 2.96¢/kWh
- At 850 kWh/month: $25.16 per month, $302 per year
Erie (Penelec):
- Default rate: 11.747¢/kWh
- Cheapest available: 10.49¢/kWh
- Savings: 1.26¢/kWh
- At 850 kWh/month: $10.68 per month, $128 per year
Pittsburgh customers who switch save more than twice as much as Erie customers, despite Pittsburgh having the higher default rate. The gap between Duquesne Light's PTC and competitive rates is unusually wide, making switching especially valuable in the Pittsburgh market.
This is a meaningful finding. Pittsburgh households pay more by default, but they can also save more by shopping. Erie households start from a lower baseline, but their upside from switching is smaller.
In both cities, switching is free, takes about five minutes, and does not interrupt service. For step-by-step instructions, see our guide to switching suppliers in Pennsylvania.
What is the same across both cities
Despite the rate differences, Pittsburgh and Erie electricity customers share more than they differ:
Same wholesale market. Both utilities purchase power through PJM. The same capacity auction results, the same coal plant retirements, and the same data center demand growth affect both territories. The 833% capacity price increase has pushed rates higher in both cities.
Same legal right to switch. Pennsylvania law gives every residential customer the right to choose their electricity supplier. Your utility cannot prevent you from switching, and the process is the same regardless of whether you have Duquesne Light or Penelec.
Same utility role. Your utility handles delivery regardless of your supplier choice. Duquesne Light still delivers power, maintains the grid, and responds to outages for Pittsburgh customers. Penelec does the same for Erie customers. Switching suppliers only changes who supplies your electricity, not who delivers it.
Same bill structure. Both utilities send a single bill that includes supply charges (from your supplier or the default rate) and delivery charges (from the utility). The mechanics work the same way.
FAQ
Why is electricity more expensive in Pittsburgh than Erie?
Pittsburgh's default rate is higher due to Duquesne Light's procurement timing, corporate structure (independent utility vs. FirstEnergy subsidiary), and rate case history. City size does not determine electricity rates — utility procurement decisions do.
Can I get the same supplier plan in both cities?
Many suppliers operate in both Duquesne Light and Penelec territories, but rates vary by utility zone. A supplier might offer 11¢/kWh in Pittsburgh and 10.5¢/kWh in Erie for the same plan name. Always check rates for your specific ZIP code.
Do I need to do anything differently when switching in Erie vs. Pittsburgh?
No. The process is identical. Enter your ZIP code on PA Power Switch or a comparison site, compare rates against your utility's Price to Compare, and enroll online with your utility account number. The switch takes one to two billing cycles to complete in both territories.
Will the rate gap change after June?
Yes. Penelec's 11.9% rate increase in June will narrow the gap significantly. Pittsburgh will still be higher, but the difference will shrink from about 2¢/kWh to less than 1¢/kWh. Rate gaps between utilities fluctuate based on procurement cycles.
