Ohio Energy Compare
Read full descriptionHide full description
Ohio Energy Compare helps you understand exactly what you're paying for electricity and natural gas — and shows you, in plain English, whether you can save money by switching suppliers. It pulls every active supplier offer directly from PUCO's official Apples to Apples data, calculates what each one would actually cost on your bill (rate plus monthly service fee, not just the sticker rate), and ranks them against your utility's default rate. No sign-up. No account. No data collection. Just real Ohio rate data, refreshed weekly. WHAT YOU'LL FIND • Your current default rate (PTC for electric, SCO for gas) and the date it's locked in through • A history chart of how that default rate has changed over the years • Wholesale market prices from the U.S. Energy Information Administration so you can sense whether rates are trending up or down • Every active competitive supplier offer — sorted by your actual yearly cost • Filters for renewable-only and no-exit-fee plans • AI-powered recommendations based on what you care about: lowest price, price stability, no commitment, clean energy, or historical value • Side-by-side comparison of any offers you're considering WHO IT'S FOR If you live in Ohio and you've never thought about your electric or gas supplier, this app is for you. Most people pay the default rate without realizing it can be 20–50% higher than fixed-rate alternatives that lock in a price for a year or more. The app makes the comparison transparent so you can decide for yourself. WHAT YOU WON'T FIND • Fees or paywalls — completely free • Sign-ups or accounts • Email collection or in-app analytics • Sales pitches — we don't sell anything; supplier links go directly to their official enrollment pages Built independently. Not affiliated with PUCO, AEP Ohio, Columbia Gas, or any utility company. Data sources: energychoice.ohio.gov (PUCO Apples to Apples), puco.ohio.gov (historical default-rate charts), eia.gov (wholesale market prices). Privacy policy: https://ohioenergycompare.com/privacy
