Oncor: delivery charges, service area, and outages
Oncor Electric Delivery owns the poles, wires, and meters that deliver electricity across Dallas–Fort Worth and much of North, Central, East, and West Texas. It doesn't sell electricity: you choose a retail provider, and Oncor's delivery charges appear on that provider's bill.
Since October 4, 2026, Oncor's residential delivery charge is 6.8673¢ per kWh plus $4.06 a month: $72.73 in a 1,000 kWh month, the same with every provider.

The basics
Oncor or your provider: who does what?
Your retail provider is the company you deal with day to day: it sells you the electricity, sets your plan's price, sends the bill, answers account questions, and offers plan features like solar buyback or battery programs. Oncor delivers the power and looks after the equipment that carries it, so you call it about outages. Your address determines your delivery utility, so every home in Oncor's area has Oncor whichever provider it chooses.

Oncor and TXU Energy both come from the old TXU Electric. When Texas opened retail electricity to competition in 2002, it was split into a delivery company (TXU Electric Delivery, renamed Oncor in 2007) and a retail provider (TXU Energy). The two shared a parent company until 2016. TXU Energy is now owned by Vistra, and Sempra has held a majority stake in Oncor since 2018.
Delivery charges
What does Oncor charge?
Oncor charges every provider the same regulated rates: 6.8673¢ per kWh plus $4.06 a month for homes, approved by the PUCT. Bills and facts labels often call this the TDU or TDSP delivery charge. Most plans pass it through, so it can change when Oncor's tariff does, even on a fixed-rate plan.

What's in the 6.8673¢
Oncor's delivery charge is several regulated charges added together. Each updates on its own schedule, which is why the total can change several times a year. From Oncor's tariff, checked November 5, 2026.

How Oncor's delivery charge has changed
In a 1,000 kWh month, Oncor delivery went from $55.21 in January 2024 to $72.73 today, and from $60.26 a year ago, a 21% rise in twelve months. Oncor has attributed its recent increases to storm restoration costs, higher operating and financing costs, and investment in resiliency and a fast-growing system. Part of today's charge is temporary: the 0.3633¢ interim surcharge runs through December 2026, and October's tracker rates await a final order.

What could change next
December 2026
A one-month mobile generation charge
Oncor bills the cost of its emergency mobile generators once a year, in December. It added 0.1027¢ per kWh to December 2025 bills; the 2026 amount isn't published yet.
January 2027
The interim surcharge ends
Rider IS runs through December 2026. Its end takes 0.3633¢ per kWh off the delivery charge, about $3.63 in a 1,000 kWh month, subject to a later reconciliation.
Pending
A final ruling on October's tracker rates
The transmission and distribution tracker rates Oncor began charging on October 4, 2026 are temporary while the PUCT reviews them in Docket 59249, Oncor's first yearly tracker filing. The final rates could differ.
March 2027
The yearly energy efficiency update
The energy efficiency charge updates each March 1. Other parts of the charge change on their own schedules, as they did in June, August, and October 2026.
Plans
What plans cost at Oncor addresses
Every plan for an Oncor address includes the same delivery charge, so plans differ in the energy price, fees, contract terms, and features such as solar buyback or EV charging.
The three standard plans listed for Oncor addresses cost 14.6¢–15.6¢ per kWh at 1,000 kWh a month, about $146–$156 with delivery included. $72.73 of each of those bills is Oncor's delivery charge, 47–50% of the total; the rest is the plan's energy charge (7.27¢ to 8.00¢ per kWh) and any base charge.

Oncor: frequently asked questions
Is Oncor my electricity provider?
No. Oncor delivers the electricity and maintains the poles, wires, and meters, but it doesn't sell electricity or send you a bill. You buy electricity from a retail electricity provider, and Oncor's delivery charges are part of that provider's bill. Oncor stays your delivery utility whichever provider you choose.
Is Oncor the same company as TXU Energy?
No. Both came from the old TXU Electric, which was split into a delivery company and a retail provider when Texas opened retail competition in 2002. TXU Energy is a retail provider owned by Vistra; Oncor is the delivery utility, 80.25% owned by Sempra. A TXU Energy customer in Dallas and a customer of any other provider on the same street both have Oncor delivering their power.
Why did Oncor's delivery charge go up in October 2026?
On October 4, 2026, Oncor began charging temporary rates from its first yearly tracker filing (PUCT Docket 59249). Its distribution cost charge restarted at 0.5755¢ per kWh after being folded into base rates in June, and its transmission charge rose to 2.1669¢. Together they added about $8.38 to a 1,000 kWh month. The rates are temporary until the PUCT issues a final order, and the final rates could differ.
Does choosing a different provider change my outages or reliability?
No. Oncor maintains the same lines and restores power the same way for every home in its area, whichever provider you use, and it charges every provider the same regulated delivery rates. Providers differ in the energy price, fees, contract terms, and features of their plans.
What does an Oncor ESI ID look like?
An ESI ID is the 17-digit number that identifies the electric service point at your address. Oncor ESI IDs start with 1044372, and a smaller set starts with 1017699. You'll find yours on a recent electricity bill, and a provider can look it up from your address when you sign up.
Where do Oncor's charges appear on my bill?
On your provider's bill. Most providers list delivery as its own line, often labeled TDU or TDSP delivery charges; some fold it into a single per-kWh price. Either way, the 500, 1,000, and 2,000 kWh prices on a plan's Electricity Facts Label include delivery.
How to read an Electricity Facts LabelHow do I start electricity at an Oncor address?
Choose a plan from a retail provider and give it your service address and move-in date. The provider sends the start request to Oncor through ERCOT, so you don't need to contact Oncor yourself. Oncor's tariff has it connect service at an existing smart meter on the requested day when the order reaches Oncor by 7 p.m. Central on any day except Sundays and holidays. Providers set their own order cutoffs and fees.
Setting up electricity in TexasDoes Oncor charge delivery on solar power I export?
No. Texas rules measure what your home takes from the grid and sends to it separately, and the per-kWh delivery charge applies only to what you take. The fixed monthly charge still applies. What you're paid for exports depends on your provider's buyback plan.
