You chose your Retail Electric Provider thinking you got a great deal. But ~40% of your DFW electricity bill is Oncor delivery charges — and those have risen 12% since 2022. Every REP passes through the same Oncor fees. The average DFW homeowner pays $160/mo and climbing.

Texas is a deregulated market — but "deregulated" does not mean "free market." In the DFW metro, Oncor is the sole Transmission and Distribution Utility (TDU). You can choose your REP for the supply charge, but every single REP passes through the same Oncor delivery charges. Here is how your bill actually breaks down:
Energy generation cost from your chosen Retail Electric Provider. This is the only part you control by shopping REPs.
Transmission and distribution fee charged by Oncor. Fixed by PUCT — your REP cannot negotiate this down.
Oncor monthly base charge ($3.42) plus ERCOT system fees, renewable surcharges, and municipal fees.
When you shop on PowerToChoose.org, you are only comparing the supply portion (~60%) of your bill. The other ~40% — Oncor delivery charges — is identical on every single plan from every REP. That "great deal" you found? It only affects 60 cents of every dollar you spend on electricity. Oncor's piece keeps growing regardless.
While REP supply rates fluctuate, Oncor's delivery charges have marched steadily upward with PUCT-approved rate increases for grid investment, storm hardening, and transmission expansion across the growing DFW metro.
| Year | Effective Rate | Oncor Delivery | Delivery Change |
|---|---|---|---|
| 2020 | 11.0¢/kWh | 3.6¢/kWh | — |
| 2021 | 11.8¢/kWh | 3.7¢/kWh | +2.8% |
| 2022 | 13.2¢/kWh | 3.9¢/kWh | +5.4% |
| 2023 | 14.1¢/kWh | 4.1¢/kWh | +5.1% |
| 2024 | 14.5¢/kWh | 4.3¢/kWh | +4.9% |
| 2025 | 14.8¢/kWh | 4.4¢/kWh | +2.3% |
| 2026CURRENT | 15.0¢/kWh | 4.5¢/kWh | +2.3% |
At the current trajectory, your $160/month DFW bill could reach $195/month by 2030 and $240/month by 2035. Over 10 years, that is an additional $4,200+ in electricity costs compared to locking in a fixed rate today. And remember — Oncor's delivery charge increases hit you no matter which REP you choose.
Every REP in Oncor territory — TXU, Reliant, Green Mountain, Gexa, Champion, Constellation — all pass through the identical Oncor delivery charges. Here is why the "Power to Choose" game has diminishing returns:
The math: If you find a REP plan that saves you 2 cents/kWh on supply, that is about $21/month savings on 1,067 kWh usage. But when Oncor raises delivery charges by another 5% next year, you lose $4-5/month of those savings immediately — and the cycle repeats every year. You are running on a treadmill.
Not all options are created equal. Here is an honest comparison.
Shop on PowerToChoose.org for a lower supply rate. Can save 5-10% on the supply portion of your bill.
Only affects ~60% of your bill (the supply charge). Oncor's rising delivery charges — the other 40% — pass through every REP plan identically. Teaser rates often jump after 12 months.
Smart thermostat, LED lights, better insulation, sealing ductwork. Good habits but limited ceiling.
Saves 10-15% on total usage, but when Oncor raises delivery rates and your REP raises supply rates, your bill climbs right back. You are fighting a losing battle against annual rate increases.
$0 down, fixed $144/mo payment — 10% less than the avg $160 DFW bill. Eliminates both supply AND delivery charges. Own the panels by year 5.
Unlike switching REPs (which only touches supply), solar eliminates your entire electric bill — supply, delivery, and fees. Your Propel payment is fixed for 25 years while Oncor keeps raising rates around you.

Texas is unique: no mandatory net metering, a deregulated supply market, and REPs that offer wildly different solar buyback terms. Here is what DFW homeowners need to know.
Texas solar advantage: DFW gets approximately 1,350 kWh per kW of solar installed per year — one of the highest solar production zones in the country. A 10.5 kW system produces roughly 14,175 kWh/year, more than enough to offset the typical DFW household usage of ~12,800 kWh/year. Excess production earns buyback credits from your REP.

$0 down. Fixed monthly payment. Own the panels by year 5. American-made Silfab 440W panels installed on your roof.
Propel financing requires FEOC-compliant (Foreign Entity of Concern) panels to qualify for the Section 48 commercial ITC. Silfab panels are manufactured in the USA with 440W output, 25-year warranty, and zero FEOC risk. They are rated for Texas heat and hail. This compliance is what makes the $0-down, fixed-payment model possible.
Oncor delivery charges have risen 12% since 2022 and show no signs of stopping. DFW homeowners are locking in fixed $144/month solar payments — less than the average $160 electric bill. Your REP cannot protect you from Oncor's next rate increase. Solar can.
