Rate Schedules & Tariff Analysis
Duke Energy Ohio C&I bills separate regulated delivery (distribution) from generation supply. Distribution is set in PUCO rate cases (Rate DS/DP/DM by voltage and demand), while generation comes from the auction-based Standard Service Offer Price to Compare or a competitive supplier. Rate DS adds a demand charge (~$6.97/kW plus riders) and tiered distribution energy charges; choosing a competitive supplier mainly affects the generation portion, not the distribution charges.
Duke Energy Ohio Rate Schedule List
| Schedule | Applicability |
|---|---|
| Rate DS (Secondary) | C&I secondary voltage, demand >15 kW |
| Rate DP (Primary) | Large C&I at 12,500/34,500 V |
| Rate DM (Small) | Small commercial/general service |

- Separate delivery and generation (deregulated)
- Voltage-based rate classes: DS (secondary), DP (primary), DM (small)

Duke Energy Ohio Data Access FAQ
Can a C&I customer download 15-minute interval data?▾
Yes. Register for the Business Experience portal, open Usage/Energy Analysis, select 15-minute granularity and a date range, and export the data as a spreadsheet or PDF. Full AMI deployment means interval data is available for essentially all accounts.
Does Duke Energy Ohio support Green Button?▾
No. There is no Green Button Download My Data or Connect My Data. Residential customers can export smart-meter usage as XML from My Account, business customers export interval data via Business Experience, and third parties use EDI (HU/HI).
How does a supplier or aggregator pull our usage data?▾
PUCO-certified suppliers, aggregators, and brokers exchange data via EDI (ANSI X12 over NAESB EDM). With a signed customer authorization, they submit HU (monthly) or HI (15-minute interval) requests; aggregators/brokers are limited to a 12-month window and pay tariff-based fees for interval requests.
Is electricity supply in Duke Energy Ohio deregulated?▾
Yes. Ohio is a retail-choice (Energy Choice) state. Duke provides regulated delivery and a Standard Service Offer (Price to Compare) set by competitive auction, while customers may instead buy generation from a PUCO-certified competitive supplier. Natural gas supply is similarly open through Ohio Gas Customer Choice.
What distribution rate applies to a commercial customer?▾
Commercial/industrial customers with average demand above 15 kW typically take Rate DS (secondary voltage); larger customers served at 12,500V/34,500V take Rate DP (primary voltage). Rate DS carries a ~$33.56/month fixed charge, a distribution demand charge (~$6.97/kW plus riders), and tiered distribution energy charges (~$0.0136-$0.0164/kWh), with generation supplied via the SSO Price to Compare or a competitive supplier.
