Oncor Electric Delivery commercial electricity
Oncor delivers power and restores outages. It does not sell the supply portion of a competitive commercial account and does not set the supply price.
Oncor Electric Delivery is the TDU serving Dallas–Fort Worth and much of north, central and west Texas. It delivers power, owns the meter and restores outages under regulated tariffs. Eligible commercial accounts contract the supply portion separately. Accounts are keyed on ESI ID.

Competitive supply market. Delivery, demand and fixed charges on an Oncor Electric Delivery account remain regulated regardless of which supplier you choose.
What the U.S. government data says about Oncor Electric Delivery
EIA’s 2025 utility sales table has no row for Oncor. So there is no utility-level figure to show here. The Texas figures, from the same source, are on the Texas page.

Cities and areas in this territory
Territory boundaries do not follow city limits. Two addresses on the same street can sit in different territories, which is why we confirm the ESI ID rather than inferring eligibility from the city or the ZIP code. Inferring from location is the most common way a commercial account is told it can do something it cannot.

Which lever moves which charge
This is the question a utility page exists to answer. If you change something at the meter, which line on the bill actually moves — and which one does not move no matter what you do?
Schematic shapes, not Oncor Electric Delivery's actual rates — those come from the filed tariff. The point is the behaviour: two of these four respond to something you control, and a supplier changes none of them.
What sits inside the delivery charge from Oncor Electric Delivery
Delivery is not one number. On a commercial account it is typically assembled from several components, each set by the filed tariff and each behaving differently as your usage changes:
- A fixed customer or meter charge, which does not move with consumption at all.
- A volumetric distribution charge per kWh, which scales with how much you use.
- A demand charge per kW where the account is demand-metered, which scales with how hard you draw rather than how much you use — and which is where a low load factor account gets hurt.
- Riders and surcharges, adjusted periodically through regulatory filings, covering items such as transmission cost recovery, energy efficiency programs and storm or system restoration costs.
None of these changes when you change supplier. Understanding the mix matters because it determines which action actually moves your bill: reducing consumption attacks the volumetric component, reducing peak draw attacks the demand component, and neither one touches the fixed charge.

Boundaries do not follow city limits. If you are not certain which of these serves your address, confirm the ESI ID printed on the bill rather than inferring it from the city.
What the Oncor Electric Delivery tariff says: Secondary Service Greater Than 10 kW (with Secondary Service Less Than or Equal to 10 kW)
Read 2026-10-30 from Oncor Electric Delivery Tariff for Retail Delivery Service, Revision Twenty-Two; Secondary Service sheets 1.2 and 1.3, Revision Twelve, effective June 1, 2026. Each figure is quoted from that document, and it is a schedule figure, not a bill estimate. See every tariff quoted on this site. The tariff and the schedule code on your bill control what applies to you.
- Who the over-10 kW schedule covers
- Secondary Service Greater Than 10 kW is for delivery at secondary voltage with demand greater than 10 kW, to one point of delivery measured through one meter, single or three-phase at a standard secondary voltage. A premise stays on it until it has completed 12 consecutive billing months with no recorded demand greater than 10 kW.
- Fixed monthly charges
- Under the monthly rate, the Customer Charge is $24.00 per Retail Customer and the Metering Charge is $20.99 per Retail Customer.
- Distribution System Charge
- Charged per Distribution Billing kW from a table (the tariff prints these figures without a currency sign). NCP kW of 20 kW or less, all annual load factors: 6.931363. NCP kW above 20 kW by annual load factor: 0% - 10% is 9.831092, 11% - 15% is 8.924995, 16% - 20% is 8.590196, 21% - 25% is 8.318122, 26% and above is 6.931363.
- How Distribution Billing kW is set
- Billing kW is the NCP kW for the current month when the highest NCP kW of the prior 11 months is 20 kW or less, or is above 20 kW with an annual load factor of 25% or less. For all other loads it is the higher of the current NCP kW or 80% of the highest monthly NCP kW in the prior 11 months (80% ratchet). NCP kW is the kW supplied in the 15-minute period of maximum use.
- Annual load factor
- The annual load factor is calculated from the previous year's usage ending with the December bill cycle and applies for the following 12 billing months.
- Billed separately
- The schedule lists the nuclear decommissioning charge (Rider NDC), transmission cost recovery factor (Rider TCRF), energy efficiency cost recovery factor (Rider EECRF), competitive meter credit (Rider CMC), distribution cost recovery factor (Rider DCRF), rate case expense surcharge (Rider RCE) and mobile generation (Rider MG) as See Rider lines. None of them is in the figures above.
- Up to 10 kW schedule
- Secondary Service Less Than or Equal to 10 kW covers secondary voltage with demand of 10 kW or less at one point of delivery and one meter, not for shared or resale. Customer Charge $2.34 and Metering Charge $4.36, each per Retail Customer; Distribution System Charge $0.031236 per kWh. Recorded demand over 10 kW three times in a rolling 12 months, or any over 12 kW, moves the premise to the over-10 kW schedule.
This page lists Secondary Service Greater Than 10 kW (with Secondary Service Less Than or Equal to 10 kW) only. The Residential, Primary Service, Transmission Service and Lighting Service schedules, and the riders and their factors, are in the tariff but are not listed here. Your schedule code is printed on the bill, and it is the first thing to look up.

- The delivery and supply sections, kept separate
- Current supplier and contract expiry, if any
