The Pennsylvania utility map, all in one place.

By Hilary Norris Updated 7 min read

Pennsylvania has 7 investor-owned utilities (IOUs), 14 rural electric cooperatives (RECs) and roughly 35 borough or city municipal systems. Find yours below and learn how PA's 1996 retail-choice market lets you shop the supply half of your bill while your local utility keeps delivering the kilowatt-hours.

Three utility types in Pennsylvania

Pick the path that matches your address

75% of PA residential customers are served by just three IOUs (PPL, PECO, Duquesne). The four FirstEnergy companies cover 60% of PA's land area but only about 35% of customers. Co-ops and munis fill the rural and borough gaps.

Rural electric cooperatives

14 PA co-ops, member-owned and not-for-profit

Pennsylvania's 14 rural electric cooperatives serve roughly 230,000 meters across 41 mostly rural counties, mainly in territory that the IOUs found uneconomic to electrify in the 1930s. Co-ops are owned by their members (you, if you live on their lines), governed by an elected board and operate at cost. Retail choice does not apply on co-op lines: the co-op generates or buys wholesale power and resells it to members at a single bundled rate. Generation and transmission for most PA RECs is handled by Allegheny Electric Cooperative, the statewide generation and transmission co-op.

Municipal electric utilities

35 PA boroughs and cities run their own electric system

From Chambersburg to Hatfield, roughly 35 Pennsylvania boroughs and small cities own and operate a municipal electric system, often dating to the 1890s or early 1900s. These munis buy wholesale power on the regional market and resell it through their own poles and meters. Municipal residents cannot shop for a competitive supplier (the borough is both your distribution and supply company), but they trade that off for lower rates: PA municipal rates average 10 to 25% below nearby IOU territories because munis do not pay shareholder dividends and skip the IOU's regulated return on capital.

The municipal trade-off is service depth: limited customer-service hours (usually weekdays only), smaller line crews for storm response and no retail-choice option. You also pay your local borough rather than a publicly listed utility.

CallMePower explains

How PA retail choice actually works

The 1996 Electricity Generation Customer Choice and Competition Act split your bill in two. Here is what you control and what you do not.

Supply (you can shop this)

The cost of the kWh you actually consume, billed in cents per kWh.

  • Default supply from your IOU's PTC if you do nothing. Reset every 1 June and 1 December.
  • Competitive supplier (EGS) if you shop on PA Power Switch. Same kWh, different price line.
  • Switch takes 1 to 2 billing cycles. No interruption, no rewiring.

Delivery (utility-only)

The cost of moving electricity through your utility's poles, wires and meter. Cannot be shopped.

  • Customer charge, a fixed monthly fee paid even at zero kWh.
  • Distribution, the cents-per-kWh wires charge approved by the PA PUC.
  • Transmission, universal service, energy-efficiency riders, small per-kWh adders set by the PUC and FERC.

The three regulators behind your PA bill

  • 1. PA Public Utility Commission (1-800-692-7380, puc.pa.gov). Approves the IOUs' delivery rates, sets the PTC default-supply auction rules and licenses every EGS.
  • 2. PJM Interconnection. The regional grid operator that dispatches generators and runs the wholesale market your supply price is built on. PJM covers 13 states plus DC.
  • 3. FERC. The federal regulator that approves PJM's market rules and your utility's interstate transmission rates.

Frequently asked questions

How do I find out which utility serves my Pennsylvania address?
Look at the top of your last electric bill: the delivery utility's name is the first thing printed. If you do not have a bill yet, your utility is set by your address, not by choice. Greater Philadelphia is PECO, Pittsburgh is Duquesne Light, most of central and eastern PA is PPL, and FirstEnergy's four PA companies (Met-Ed, Penelec, Penn Power, West Penn) cover most of the rest. If you live in one of 35 PA boroughs with a municipal utility, your bill comes from the borough hall. The PA PUC also publishes a free address-lookup tool on PAPowerSwitch.com.
Can I switch to a cheaper electricity supplier in PA?
Yes, if you live on the lines of one of the 7 PA IOUs. You can shop the supply portion of your bill on PAPowerSwitch.com, comparing against your utility's Price to Compare. Co-op and municipal members cannot switch suppliers, because their utility owns both delivery and supply. The switch takes 1 to 2 billing cycles, your utility keeps delivering the same kWh, and the only thing that changes is the supply line on your monthly statement.
What is the Price to Compare and when does it change?
The PTC is the cents-per-kWh rate your utility charges for default supply when you do not pick a competitive supplier. It is set by a procurement auction run by your utility under PUC rules, and resets every 1 June and 1 December for residential customers. Comparing a competitive supplier's all-in rate to the current PTC is the only honest apples-to-apples shop. The PTC is printed on every bill.
Why are municipal rates lower than IOU rates in PA?
Three reasons. Municipal utilities are not-for-profit, so there is no shareholder return baked into the rate. Their distribution systems are small, geographically dense and largely depreciated. And they buy wholesale power directly on the regional market instead of running a six-month default-supply auction with a built-in risk premium. The trade-off is service depth: a borough may have only one or two line crews for storm response, and customer service is usually weekdays only.
My power is out, who do I call?
Always your delivery utility, 24/7. PPL Electric: 1-800-342-5775. PECO: 1-800-841-4141. Duquesne Light: 1-888-393-7000. FirstEnergy (Met-Ed, Penelec, Penn Power, West Penn): 1-888-544-4877. Co-op and municipal customers should call the number printed on the top of their bill.
What is PJM and why does it matter?
PJM Interconnection is the regional grid operator that dispatches generators and runs the wholesale electricity market across 13 states plus the District of Columbia, including all of Pennsylvania. PJM matters to your bill because the wholesale prices set in PJM's day-ahead and real-time markets are what your utility (or competitive supplier) pays to buy the power you eventually use. When PJM capacity prices spike, as they did in the 2025 to 2026 auctions, your Price to Compare follows roughly six months later.
