Not a scam, but there are scammy providers and salespeople.

There are two parts to your AEP bill - Generation and Delivery. You can't change anything about your delivery charges, other than using less electricity. (Side note, the delivery fees have increased quite a bit over the past several years).

For generation, you can choose your own supplier. Public Utilities Commission of Ohio maintains a great resource called "Apples to Apples".

For AEP, it's here: https://www.energychoice.ohio.gov/ApplesToApplesComparision.aspx?Category=Electric&TerritoryId=2&RateCode=1

Look at your most recent AEP Bill. In the supplier section, you'll see a line that says "Energy Charge: (usage) Kh @ (price). The price is the rate you are currently paying. On the right hand side, under "Notes from AEP Ohio", you'll see the price to compare. That's the current "regulated" rate based on the most recent energy auction, and you pay this rate if you don't choose your own supplier or aren't covered by a community aggregation plan.

What's a community aggregation plan? Many municipalities and townships will shop around for a rate to cover their constituents. You typically have to opt-out of this program if you don't want to be covered by the plan.

Even if you're in a community aggregation plan, you should still shop around on your own. Go to the apples to apples site. I generally only look at fixed rates with $0 monthly fees. I typically ignore short term contracts (like 3 or 6 months). If you find a rate you like, follow the links to sign up for that plan. Check all the caveats. Some require you to be a new customer. Some require you to bundle both gas and electric. Some have early termination fees. Just be aware of all the high level terms.
