Where do the numbers for the Illuminating Company come from?

Each rate was read from PUCO's Illuminating Company historical chart. The newest two periods came from PUCO's Energy Choice Ohio chart. We entered each figure by hand, checked it against a second read of the page, and last read the charts on October 1, 2026.

PUCO prints electric rates in dollars per kWh. We multiply by 100 to show cents, which changes only the unit, and keep each cell's original text in our data.

Are there gaps or odd dates in the record for the Illuminating Company?

PUCO's printed dates leave 2 days between July 1 – August 31, 2024 and September 3 – September 30, 2024. We leave this gap as PUCO prints it.

PUCO's May 4, 2023 news release lists a figure for June 1 – June 30, 2023 that matches after rounding. PUCO says the figures in that release reflect tariffs as filed and are subject to Commission authorization.

How does the history of the Illuminating Company rates help when you compare offers?

This record shows how far and how often the default has moved. It does not give the next rate. The newest period, October 1 – December 31, 2026, is the one in force today.

Today's figure and the next reset are on our Illuminating Company price to compare page. PUCO's historical chart says historic rates "are not indicative of future market conditions or prices."

The Illuminating Company Apples to Apples chart lists current offers, our offer checker shows what a supplier's monthly fee adds to the rate per kWh, and energy choice in Ohio explains switching. Staying on the default can be the better choice when every fixed offer is above it, when fees erase the gap, or when you may move before a fixed term ends and would owe its early termination fee.

We are a broker. Suppliers pay us a commission when a household enrolls, and we also charge a service fee. There's no cost to check, and you see the fee terms in your offer.
