Quick Answer

Oncor delivery charges make up a significant portion of your Texas electric bill. These charges are regulated by the PUCT and appear on every bill in Oncor territory regardless of your REP. Here is exactly what Oncor charges, why the amounts may seem high, and what you can realistically do about delivery costs.

What Are Oncor Delivery Charges?

Oncor delivery charges are the regulated fees that cover the cost of physically delivering electricity from power plants to your home. Oncor owns and maintains over 140,000 miles of power lines, tens of thousands of transformers, and millions of electric meters across North, Central, and West Texas.[1]

Oncor delivery charges are not set by your REP. They are approved by the Public Utility Commission of Texas (PUCT) through a regulatory rate case process. Every customer in Oncor territory pays the same delivery tariff regardless of which REP they choose. Your REP collects Oncor's charges on their behalf and passes them through on your bill.

These charges are separate from your energy charge—the per-kWh rate you shop for when comparing plans. You control your energy rate by choosing a competitive REP. You cannot control Oncor delivery charges. Understanding this split helps explain why your total bill is higher than just the advertised rate.

Oncor Delivery Charge Breakdown: What Each Fee Covers

Oncor delivery charges include several line items. Each covers a specific part of the delivery infrastructure.[2]

Customer charge (fixed monthly fee): A flat fee charged to every Oncor customer regardless of usage. This covers meter maintenance, billing system costs, and basic service. Currently around $3.42 per month for residential customers.

Metering charge: Additional fixed fee for advanced metering infrastructure (smart meter) costs. Typically around $2.19 per month.

Distribution delivery charge (per kWh): A variable charge based on your actual electricity consumption. This is the largest delivery component—covering the local power lines and transformers that bring electricity from substations to your home.

Transmission cost recovery factor (per kWh): Covers Oncor's cost of using the high-voltage transmission system to move power from generators to Oncor's distribution network.

System benefit fund and other riders: Small per-kWh charges funding low-income assistance, renewable energy mandates, and other regulatory requirements.

Combined, Oncor delivery charges typically total $40-70 per month for a household using 1,000 kWh—roughly 4-5 cents per kWh on top of your energy rate.

Why Oncor Delivery Charges Seem So High

Many Texas electricity customers are shocked when they see Oncor delivery charges for the first time. Several factors explain why these fees feel disproportionate.

Delivery is 30-40% of your total bill. When you shop for an electricity plan at 9 cents per kWh, you might expect a $90 bill for 1,000 kWh. But delivery charges add $40-70 on top, bringing your real cost to 13-16 cents per kWh. The advertised rate only covers the energy portion.

Fixed charges hit low-usage customers hardest. The customer charge and metering charge are flat monthly fees. A household using 500 kWh absorbs those fixed costs across fewer kilowatt-hours, making the per-kWh delivery impact larger.

Infrastructure costs are rising. Oncor is investing billions in grid modernization—burying power lines, upgrading substations, deploying advanced grid technology. These capital investments get recovered through delivery charges approved by the PUCT.

Storm recovery costs. Major weather events like Winter Storm Uri (2021) caused infrastructure damage that Oncor recovers through surcharges over time. These temporary riders gradually add up.

The comparison trap: Texas REPs advertise the energy rate, not the all-in rate. This makes bills look higher than expected when delivery charges are included.

How Oncor Delivery Charges Change by Usage

Oncor delivery charges are not a flat percentage. The fixed monthly fees stay constant while the per-kWh charges scale with usage. This creates different effective delivery rates at different consumption levels.

At 500 kWh/month: Fixed charges ($5-6) plus per-kWh charges. Effective delivery rate: approximately 5.5-6.5 cents per kWh. The fixed fees have a larger per-kWh impact at low usage.

At 1,000 kWh/month: The most common benchmark. Effective delivery rate: approximately 4.5-5.5 cents per kWh. Fixed fees are diluted across more kilowatt-hours.

At 2,000 kWh/month: Large home with heavy AC usage. Effective delivery rate: approximately 4.0-4.5 cents per kWh. Per-kWh charges dominate while fixed fees become negligible.

Key insight: High-usage customers pay more in total delivery dollars but less per kWh. Low-usage customers (apartments, efficient homes) pay less total but more per kWh. This is why shopping at your actual usage level matters—plan rates that look cheap at 1,000 kWh may not account for how delivery charges affect your specific consumption pattern.

Oncor Delivery Charges vs Other Texas TDUs

Oncor's delivery charges fall in the middle of the pack among Texas TDUs. Comparing across TDUs shows why location matters for your total electricity cost.

CenterPoint Energy (Houston): Delivery charges are generally similar to Oncor. CenterPoint's per-kWh delivery rate is slightly higher in some tariff components, but the total difference is modest—typically $5-10 per month at 1,000 kWh.

AEP Texas (South and West Texas): AEP Texas delivery charges run slightly higher than Oncor in most tariff classes. Rural infrastructure serving a smaller, more spread-out customer base drives higher per-customer costs.

TNMP (scattered Texas areas): TNMP delivery charges are typically the highest among major TDUs due to the smallest customer base and scattered service territory. Fewer customers share infrastructure costs.

LP&L (Lubbock): Newly deregulated, LP&L delivery charges are still stabilizing as the transition from municipal utility to TDU continues.

You cannot change your TDU. Moving from an Oncor area to a CenterPoint area might slightly change your delivery costs, but this is not a factor you can shop for. Focus on reducing your energy rate—that is the variable you control.

How to Reduce the Impact of Oncor Delivery Charges

Oncor delivery charges are regulated and non-negotiable. You cannot shop for a lower delivery rate. But you can take strategic steps to minimize their impact on your total electricity cost.

Reduce your usage. Per-kWh delivery charges decrease with lower consumption. A smart thermostat, LED lighting, and efficient appliances directly reduce both energy and delivery costs. Every kWh you do not use avoids both the energy charge and the delivery charge.

Shop aggressively on the energy rate. Since you cannot control delivery, maximize savings on the portion you can control. Even a 1-cent-per-kWh difference in energy rates saves $10-20/month at typical usage. Use ElectricRates.org to find the lowest energy rates.

Understand the EFL at your usage. The Electricity Facts Label shows all-in rates (energy + delivery) at 500, 1,000, and 2,000 kWh. Compare these all-in numbers rather than just the advertised energy rate.

Consider solar. Rooftop solar reduces kWh pulled from the grid, directly lowering both energy and delivery charges. Solar buyback plans can further offset costs.

How Oncor Delivery Rates Get Set: The PUCT Rate Case

Oncor delivery charges do not change arbitrarily. The PUCT sets rates through a formal rate case process that takes months and involves public input.[3]

How the process works:

Oncor files a rate case with the PUCT, proposing new delivery rates based on projected costs, capital investments, and customer growth.

Intervenors review the filing. Consumer advocacy groups, the Texas Industrial Energy Consumers, cities within Oncor's territory, and PUCT staff all examine the proposal. These parties often argue that Oncor's requested rates are too high.

Administrative law judges hold hearings. Evidence is presented, cross-examination occurs, and both sides make their case. Think courtroom proceedings for your electric bill.

The PUCT commissioners vote on a final order setting rates. The approved rates are typically lower than what Oncor requested and higher than what consumer groups proposed—a compromise.

New rates take effect and remain until the next rate case, typically every 2-4 years.

You can participate by filing comments during open PUCT proceedings. Cities within Oncor's territory often intervene on behalf of residents. Check our TDU charges guide for more context on how regulated charges work across Texas.

Frequently Asked Questions

Why is my Oncor delivery charge so high?

Oncor delivery charges cover the cost of maintaining 140,000+ miles of power lines, transformers, meters, and substations across Texas. At 1,000 kWh, delivery typically adds $40-70 to your bill. Fixed monthly fees hit low-usage customers especially hard on a per-kWh basis. These charges are regulated by the PUCT and are the same regardless of your REP.

Can I avoid Oncor delivery charges?

No. Oncor delivery charges are mandatory for all customers in Oncor territory regardless of which REP you choose. These regulated charges cover the physical infrastructure that delivers electricity to your home. The only way to reduce delivery costs is to reduce your electricity usage, which lowers the per-kWh portion of delivery charges.

Do Oncor delivery charges change by REP?

No. Oncor delivery charges are identical for all customers in the same rate class, regardless of which REP you use. Your REP collects Oncor's charges on their behalf. The only bill difference between REPs is the energy charge—the supply portion of your rate that you can shop for.

How much are Oncor delivery charges per kWh?

Oncor delivery charges work out to approximately 4-5.5 cents per kWh at typical residential usage (1,000 kWh). The exact amount depends on your usage level because fixed monthly fees are spread across more kilowatt-hours at higher consumption. At 500 kWh, the effective rate is closer to 5.5-6.5 cents. At 2,000 kWh, it drops to around 4-4.5 cents.
