If you live in Dallas, Fort Worth, Arlington, Plano, Frisco, or anywhere across North and West Texas, your monthly electricity statement contains two distinct categories of charges: the energy supply charge from your retail electric provider, and the delivery charges from Oncor Electric Delivery.
Many Texas consumers assume that shopping for a low advertised rate per kilowatt-hour covers their entire bill. When the bill arrives and the effective rate is 4¢ to 5¢ higher than the advertised price, surprise and frustration follow.
Understanding how Oncor delivery fees are structured, why they fluctuate, and how they factor into your total invoice is critical to protecting your household energy budget.
Oncor TDU delivery charges are regulated pass-through fees approved by the Public Utility Commission of Texas (PUCT) to cover the cost of transmitting and delivering electricity across the Oncor service territory (including Dallas-Fort Worth, North Texas, and parts of West Texas). As of 2026, Oncor charges residential customers a flat base customer fee of $4.39 per month plus approximately 4.54¢ per kilowatt-hour (kWh) delivered. Every resident in Oncor territory pays these exact same delivery fees regardless of which retail electric provider they choose.
What Is Oncor Electric Delivery?
To understand your monthly bill, it helps to distinguish the company that delivers your electricity from the company that sells it to you. The Texas retail electricity market operates under a deregulated structure managed by the Electric Reliability Council of Texas (ERCOT):
- Your Retail Electric Provider (REP): Companies such as TXU Energy, Reliant, Champion Energy, or TriEagle buy wholesale power, design retail rate plans, handle customer billing, and provide customer support.
- Your Transmission and Distribution Utility (TDU): Oncor is the regulated wires-and-poles utility. Oncor owns more than 140,000 miles of transmission and distribution lines, operates local substations, installs and reads digital smart meters, and dispatches lineworkers to restore power during storm outages.
Oncor is the largest electric delivery utility in the state of Texas, serving more than 10 million consumers across nearly 400 cities and 120 counties.
Under PUCT regulations, retail providers are prohibited from marking up Oncor charges. They collect these delivery fees directly from you on your monthly bill and remit 100% of the funds back to Oncor.
Line-Item Breakdown of Oncor Residential Delivery Rates
Oncor charges are divided into a flat monthly customer fee and a volumetric per-kWh rate based on the exact amount of power your home consumes.
| Tariff Component | Billing Basis | Purpose / Infrastructure Investment |
|---|---|---|
| Customer Charge | $4.39 per month | Base fee to maintain account administration, customer service, and meter maintenance. |
| Transmission Cost Recovery Factor (TCRF) | Volumetric (~1.28¢ / kWh) | Covers high-voltage transmission lines moving power from power plants to local city gates. |
| Distribution Cost Recovery Factor (DCRF) | Volumetric (~2.15¢ / kWh) | Funds local neighborhood distribution poles, transformers, underground cables, and substations. |
| System Restoration & Securitization | Volumetric (~0.63¢ / kWh) | Pays off statutory bond financing for severe storm repairs and grid reconstruction. |
| Energy Efficiency & Regulatory Cost Recovery (EECRF) | Volumetric (~0.48¢ / kWh) | Reimburses state-mandated residential energy efficiency and conservation incentive programs. |
| Total Effective Volumetric Delivery Rate | ~4.54¢ per kWh | Total variable delivery charge applied to every kWh of electricity delivered. |
Note: Individual tariff riders are reviewed and adjusted semi-annually with PUCT approval. The combined volumetric rate of ~4.54¢ per kWh represents current approved tariffs for residential service in Oncor territory.
The "So What?" Math Bridge: Real DFW Bill Calculations
To see how Oncor delivery charges affect your monthly expenses, consider three typical household scenarios based on a competitive fixed energy rate of 11.5¢ per kWh from your chosen provider.
| Bill Component | Apartment / Condo (500 kWh) | Single-Family Home (1,000 kWh) | Peak Summer Home (2,000 kWh) |
|---|---|---|---|
| Oncor Customer Base Charge | $4.39 | $4.39 | $4.39 |
| Oncor Volumetric Delivery (4.54¢/kWh) | $22.70 | $45.40 | $90.80 |
| Total Regulated Oncor Delivery | $27.09 | $49.79 | $95.19 |
| Provider Energy Charge (11.5¢/kWh) | $57.50 | $115.00 | $230.00 |
| Total Monthly Electricity Bill | $84.59 | $164.79 | $325.19 |
| Oncor Delivery Share of Bill | 32.0% | 30.2% | 29.3% |
In North Texas, triple-digit summer heat often causes cooling usage to surge beyond 2,500 or 3,000 kWh for homes with multiple A/C units or swimming pools. In those months, Oncor delivery fees alone can easily exceed $120 to $140. Learn more about identifying hidden charges in our Texas Electricity Facts Label (EFL) Guide.
How Oncor Delivery Rates Compare Across Texas
While delivery fees are a significant line item on North Texas electric bills, Oncor’s volumetric delivery rate remains among the most competitive across the state. Below is an interactive comparison of the regulated delivery tariffs approved by the PUCT for all five major Texas utility networks:
Why Do Oncor Rates Adjust Twice a Year?
Under the Public Utility Regulatory Act (PURA) in Texas, regulated utilities do not set their own prices arbitrarily. Delivery rates are adjusted twice annually, taking effect on March 1 and September 1, following formal review by the PUCT.
Several primary cost factors influence Oncor rate updates:
- North Texas Population and Housing Influx: The Dallas-Fort Worth metroplex adds tens of thousands of new residential meters every year. Expanding substation capacity, running new feeder lines, and interconnecting new housing developments in Frisco, Celina, Prosper, and Fort Worth requires continuous capital deployment.
- Distribution Cost Recovery Factor (DCRF): Texas statutes allow utilities to file DCRF applications to recover capital expenditures made for distribution system reliability without undergoing a multi-year, full-blown rate case.
- Transmission Grid Expansion for Renewable Integration: Oncor plays a central role in transmitting wind and solar generation from West and Central Texas to major demand centers in DFW. As new solar farms and data centers come online, high-voltage transmission investments increase.
- Severe Weather Hardening: Following extreme winter events and summer windstorms, Oncor has invested heavily in digital grid automation, self-healing circuit switches, smart sensors, and expanded vegetation management along overhead rights-of-way.
How Oncor Charges Appear on Your Electricity Facts Label (EFL)
Every electricity plan offered in Texas must provide a standardized Electricity Facts Label (EFL). When reviewing an EFL in Oncor territory, pay close attention to how delivery charges are presented:
1. Unbundled Plans (Standard Pass-Through)
The vast majority of competitive retail plans feature unbundled pricing. The marketing material will emphasize the provider's base energy charge (for example, "8.5¢ per kWh"). In the fee disclosure section, the EFL will state: "Plus Oncor Electric Delivery charges will be passed through to customer without markup."
When you see advertised average rates calculated at 500, 1,000, and 2,000 kWh, the math includes Oncor’s current delivery fees. If Oncor updates its tariffs during your contract, your bill will reflect the new delivery charge, but your provider's base energy rate remains locked.
2. Bundled Plans (All-Inclusive)
Some retail providers offer bundled plans where one flat rate covers both energy and delivery (for example, "13.5¢ per kWh total"). While this simplifies billing, providers often build an extra safety margin into the rate, which can lead to higher overall annual costs compared to a competitively priced unbundled fixed plan.
Can You Choose a Utility Other Than Oncor in DFW?
No. In Texas, retail electricity supply is deregulated and competitive, but the physical delivery infrastructure remains a regulated geographic monopoly.
If your property is situated within Oncor's service boundary, Oncor is the only company authorized to deliver electricity to your meter. You cannot switch to CenterPoint or another utility.
However, you have complete freedom to choose your Retail Electric Provider.
Because Oncor's delivery fees are fixed across all providers, the only way to lower your overall electricity expenditure is to reduce the energy charge portion of your bill. By switching to a provider with a lower locked-in rate, you directly counteract delivery costs.
4 Practical Ways to Lower Your Electric Bill in Oncor Territory
To keep your total monthly energy costs as low as possible:
- Lock In Fixed-Rate Certainty: Avoid month-to-month variable rates and expired contract holdover pricing. A 12-month or 24-month fixed contract protects you against wholesale electricity price volatility during extreme weather.
- Exercise the 14-Day Free Switch Window: Under PUCT Rule §25.475, you have the legal right to switch electricity providers up to 14 calendar days before your current contract ends without paying an Early Termination Fee (ETF).
- Beware Bill-Credit Usage Traps: Plans that advertise low rates often rely on strict bill credit windows (such as $100 off only if you consume between 1,000 and 1,500 kWh). If your consumption drops to 950 kWh in mild spring weather or climbs to 1,600 kWh in summer, your effective rate per kWh can surge drastically.
- Compare Plans Using Actual Smart Meter History: Do not estimate your consumption using generic averages. In North Texas, your summer electricity consumption can be two to three times higher than your winter consumption.

Frequently Asked Questions
What are Oncor's current delivery charges in Dallas-Fort Worth?
Oncor charges a $4.39 flat monthly customer base charge plus a combined volumetric delivery rate of about 4.54¢/kWh — roughly $49.79 in delivery charges at 1,000 kWh. The volumetric total combines the Transmission Cost Recovery Factor (~1.28¢/kWh), the Distribution Cost Recovery Factor (~2.15¢/kWh), System Restoration and Securitization (~0.63¢/kWh), and the Energy Efficiency and Regulatory Cost Recovery rider (~0.48¢/kWh). Individual tariff riders are reviewed semi-annually under PUCT approval, with updates typically effective March 1 and September 1.
Can I avoid Oncor delivery fees by choosing a different provider?
No. Oncor's charges are regulated and identical across every retail provider in North Texas — providers are prohibited from marking them up and remit 100% of the funds back to Oncor. Because Oncor owns the poles, wires, and smart meters across nearly 400 cities and 120 counties, there is no competing delivery utility in its territory. The only lever you control is the provider's base energy supply rate; a bundled all-in plan can fold delivery into one rate but usually builds in an extra margin.
Will my Oncor delivery rate change while I am under contract?
It can. Under PURA, Oncor's delivery rates are adjusted twice a year — effective March 1 and September 1 — following formal PUCT review. If Oncor updates its approved tariffs during your term, your monthly bill reflects the new delivery charge while your provider's locked base energy rate stays unchanged. In peak summer, when North Texas cooling usage can push past 2,500 kWh, a mid-contract delivery adjustment lands on top of an already elevated bill.
