What the default rate has done
Quarterly resets set by PUCO auctions.
The default rate (PTC/SCO) is what you pay if you never pick a supplier. It resets every quarter based on auctions — so your bill can move even if you do nothing.
The Default Rate If You Haven’t Switched (PTC History)
AEP OhioShowing the utility you selected in the top bar — changing it there updates Compare, Your Bill, and every other section.
If you haven't picked a different electricity supplier, you're paying AEP Ohio's "Price to Compare (PTC)" — that's the rate you automatically get if you don't switch. Think of it like the "sticker price" before you shop around. It resets approximately every 3 months (quarterly), so what you pay can change multiple times a year without you doing anything. The exact schedule varies by utility. The chart below shows each of those quarterly rates over time.
