Quick answer
How much has AEP Ohio’s rate changed since I last shopped? The chart below shows every approved residential rate revision for AEP Ohio on file with the URDB. Scroll to compare today’s rate against the same month in any prior year — the gap is what a non-shopping customer has absorbed.
How much has AEP Ohio’s rate gone up since I last shopped?
AEP Ohio's residential Standard Service Offer (SSO) — the default rate that runs on every customer's bill unless they choose a competitive supplier — gets reset through PUCO-approved auctions. The revisions below capture each approved change to that default rate, going back to the start of structured tariff filings in the URDB. AEP Ohio customers who never switched suppliers paid each one of these rates in turn.
Rate increases compound. A 10% step-up isn’t paid once — it’s the floor under every kWh you’ll buy until the next reset. Three of those in a decade is the difference between a household that pays attention at contract renewal and one that doesn’t. That’s the case for keeping a per-utility historical view honest and in one place.

How to read this history if you're shopping for a better rate
A Columbus household on 1,000 kWh/month who stayed on AEP Ohio's default service through every SSO reset paid the rates in this chart, year by year. A neighbor on a fixed-rate competitive supplier locked in below market would have rolled past several of these increases — that's the case for shopping the Apples to Apples list every contract cycle.
Three useful comparisons
- Today vs. five years ago. Look at the most recent revision in the chart against the one effective ~5 years before. That's the compounded shift — the lift a non-shopping customer absorbed.
- Today vs. recent low. The lowest rate in the past three years is the rough floor a competitive supplier could have offered at the time. If today's rate is well above that floor, a fixed-rate offer locked in at the low would still be saving its customer money right now.
- Step size of changes. Are revisions small and frequent, or large and rare? Large step-ups are the moments where switching ahead of the change pays the most — and they show up clearly in the chart as steep stair-treads.
Methodology & sources
Revisions on this page come from the U.S. Utility Rate Database (URDB) , maintained by the National Renewable Energy Laboratory (NREL). URDB aggregates approved residential, commercial, and industrial tariff filings — the same documents utilities file with their state public utility commissions.
We filter to AEP Ohio's residential default service (the rate non-shopping customers pay), sorted by effective date, and show every approved revision back to the earliest URDB record for the utility. The "source" link on each revision in the table points to the original tariff filing PDF on the utility or commission website.
Refresh cadence: URDB updates daily as new tariff filings are approved. We re-sync monthly and update this page on the next deploy. The "last updated" date at the top of the page reflects the most recent sync.
Service territory: Central and Southern Ohio, Columbus metro.
URDB is public-domain federal data (NREL / U.S. Department of Energy). Attribution is courtesy, not required — we cite it because the source matters.
