Enter your ZIP code and you'll see live generation rates from PUCO-certified suppliers serving Mason on the Duke Energy Ohio grid. Ohio deregulated retail electricity in 2001 under Senate Bill 3, overseen by the Public Utilities Commission of Ohio (PUCO). Duke Energy Ohio still delivers the power and handles the wires, but the generation portion of your bill — usually 40-60% of the total — comes from whichever supplier you pick. Compare each offer against Duke Energy Ohio's Standard Service Offer (SSO) rate, which is the default Mason residents pay if they don't shop. Watch for monthly fees, introductory rates that reset after 3-6 months, and early cancellation charges hidden in the contract summary.
The cheapest generation rate in Mason typically lands between 5¢ and 7¢ per kWh on a 12-month fixed plan from a PUCO-certified supplier — but the headline rate isn't the whole story. Some bill-credit plans look cheap at 1,000 kWh of usage and lose money below 800 kWh; others bury a $9.95 monthly fee that erases the savings. The honest comparison is against Duke Energy Ohio's current SSO rate, which resets seasonally. Take your last 12 months of kWh from your bill and compare each supplier offer's total monthly cost at your actual usage — that's how you tell whether an offer beats SSO for your home, or just looks better on a rate sheet.
Ohio doesn't have one flat statewide rate. Mason sits in Duke Energy Ohio's service territory — one of six EDUs (AEP Ohio, Duke Energy, AES Ohio, Ohio Edison, Toledo Edison, Cleveland Illuminating) — and each EDU has its own delivery charges and SSO generation rate set by PUCO. So a Mason household pays different delivery rates than a Cincinnati or Toledo household, even on the same supplier plan. The supply side is competitive: you can pick any PUCO-certified supplier statewide, but the delivery side stays with Duke Energy Ohio and doesn't change when you switch suppliers. Two neighbors on the same Mason street can pay very different total bills depending on when each one shopped.
