The short answer
PA is deregulated for electricity statewide.
Pennsylvania is fully deregulated for electricity statewide. Major utilities are PECO (Philadelphia metro), PPL Electric (central PA), Duquesne Light (Pittsburgh metro), and West Penn Power (western/northwestern PA). PaPowerSwitch.com is the PUC's official rate-comparison portal, and the Price-to-Compare (PTC) is the utility default benchmark. This guide explains the structural mechanics of supplier choice in PA, the PTC benchmark, and how to read the supplier license registry.
How the Price-to-Compare (PTC) benchmark works
When a Pennsylvania customer does nothing, supply defaults to the utility's Price-to-Compare. The PTC is recalibrated quarterly or semi-annually based on a wholesale auction plus the utility's procurement costs. It is the rate the utility charges anyone who has not chosen a competitive supplier.
The PTC has the same structural property as Ohio's SSO: it floats with the market, is priced conservatively to cover worst-case wholesale spikes, and carries no contract terms in your favour. Most months a competitive supplier offer prices under the PTC.
PaPowerSwitch shows the current PTC for each utility and ranks competitive offers by rate.
How to verify a supplier license on the PA PUC site
Every supplier operating in Pennsylvania holds a state PUC license. The license is public and verifiable on the PUC's supplier-license registry. Before signing a contract, confirm the supplier has an active PA license — Seenra only sources offers from licensed suppliers.
The license registry also shows the supplier's operating territory (some suppliers are PECO-only, some statewide), the contract types they offer, and the current customer count.

PA utility vs supplier — what each side owns
How PJM pricing flows through to PA supplier offers
Pennsylvania, like Ohio, sits inside PJM. The wholesale market that prices supplier offers is PJM, and the capacity auction (which sets the delivery-side capacity charge) is also PJM.
PA spans two PJM zones — PECO zone (Philadelphia metro) and PPL/MetEd/PennElec zone (central and western). Supplier offers vary slightly across zones based on basis differentials.
Recap
Bottom line
Pennsylvania has been fully deregulated for electricity since 2000, and the supplier market is mature with dozens of licensed suppliers competing for residential and commercial customers. PaPowerSwitch is the PUC-run comparison portal; the Price-to-Compare (PTC) is the utility default benchmark every supplier offer is graded against.
For Pennsylvania households, the optimal play is locking a 12 to 24-month fixed-rate contract below the current PTC, with no introductory period and no early-termination fee. PJM capacity dynamics flow through to the delivery side regardless of supplier choice — PJM 2026 capacity auction cleared at decade-high prices, driving 8 to 15 percent rate increases that locked supply contracts cannot fully insulate against. The how-to-use-papowerswitch and capacity-charge-line-item-explained guides cover the operational context.
