If your Round Rock home is on Oncor's network, you're in a retail choice area, which means you decide which company sells you electricity and on what terms. Oncor still owns and runs the local lines, and it delivers your power the same way no matter who sends the bill. That leaves retail providers competing on what you can actually compare: price per kilowatt-hour, contract length, fees and service.
Our rates table pulls live prices for Oncor addresses in Round Rock. Below it, you'll find this month's market numbers, a plain-English look at how the cheapest plans are built, and the details worth checking on each Electricity Facts Label (EFL), the price disclosure every Texas plan must have. We checked these prices on November 4, 2026, and we update the page every month.

The snapshot below is from November 4, 2026. Prices are averages per kilowatt-hour (kWh) for a home using 1,000 kWh in a month, including Oncor's delivery charges, unless a different usage level is named.
The plans in our Round Rock table whose prices we confirmed that day run from 7.4¢ to 9.0¢ per kWh.
Power to Choose, the state's official shopping site, listed 171 plans from 42 providers for Oncor addresses.
On Power to Choose, standard fixed-rate plans (not prepaid or time-of-use) ran from 6.2¢ to 16.3¢; 75 of the 147 were 13.1¢ or less, and a typical 12-month fixed plan cost 13.0¢.
Bill-credit plans held the lowest prices on Power to Choose, at 6.2¢, 6.9¢ and 7.4¢, while the same type of plan cost 18.0¢ to 27.0¢ per kWh at 500 kWh.
For 12-month plans with no bill credit, the floor on Power to Choose was 12.0¢, and the three cheapest stayed within 11.8¢ to 12.4¢ across 500, 1,000 and 2,000 kWh.
Oncor's delivery charges are $4.06 per month plus 6.8673¢ per kWh, per an EFL dated October 4, 2026, or $72.73 at 1,000 kWh before any energy charges.
Statewide, Texas homes paid an average of 15.91¢ per kWh in August 2026, according to preliminary figures from the U.S. Energy Information Administration (EIA).
What this means for you: anything above about 13¢ on a fixed plan, or a month-to-month rate you never chose, is worth replacing this month.
Look across the 500 kWh column of our Round Rock table and every plan starts above 20¢. At 1,000 kWh, the four cheapest fall to between 7.4¢ and 9.0¢. 4Change Energy's Maxx Saver Value 12 and Frontier Utilities' Frontier Saver Plus 12 share the lowest prices at 20.3¢, 7.4¢ and 13.4¢ for 500, 1,000 and 2,000 kWh. Frontier Saver Plus 24 shows 21.3¢, 8.4¢ and 14.5¢, and Maxx Saver Value 24 shows 22.0¢, 9.0¢ and 15.1¢.
A drop that steep points to a usage credit that only lands in months when you reach a set amount of power. Frontier advertises up to $1,500 in usage credits a year on its Saver Plus plans. 4Change's listing doesn't give the credit amount or the usage it needs, so check both on the EFL before you sign.
The practical test is simple. Pull up your usage for the past 12 months and look at the lowest month. If even that month reaches about 1,000 kWh, these plans can be the cheapest way to power a Round Rock home. If spring, fall or winter usage dips well below that, a plan whose price stays level across usage will probably cost less over the year. Our guide to reading an Electricity Facts Label shows where the credit terms are printed.
Judge any rate at the usage your home really has. The headline price is usually the 1,000 kWh figure, but every EFL also shows 500 and 2,000 kWh, and the cheapest plan can change between them.
As of November 2026, about 12¢ per kWh or less at your own usage on a 12-month fixed plan is a good price in Round Rock.
At 16¢ per kWh, you'd be paying more than the 15.91¢ Texas average and well above the 13.0¢ typical 12-month plan on Power to Choose, so shop around.
When a contract ends and you don't pick a new plan, you land on a month-to-month rate that is very likely higher than anything in our table. You can leave it at any time without a cancellation fee.
Your smart meter keeps a record of every month. Smart Meter Texas, the official state portal for meter data, shows your history for free, or you can total the kWh from a year of bills. According to the EIA, the average Texas home used 1,096 kWh a month in 2024.
Three things drive most high bills.
Air conditioning: summer cooling can run much of the day, so usage climbs sharply in the hottest months, and a plan chosen for its 1,000 kWh price can look different at your summer peak.
Delivery charges: Oncor bills $4.06 a month plus 6.8673¢ per kWh to maintain the poles, wires and meters, and every provider passes the cost straight through. Measured against the typical 13.0¢ 12-month plan on Power to Choose, delivery is more than half of a 1,000 kWh bill. The Public Utility Commission of Texas (PUCT) approves these charges and lists the current delivery rates for every Texas utility.
Rolling off a contract: when your fixed term expires without a replacement, your rate becomes variable and can change from bill to bill.
You can't control the weather or Oncor's charges, but you can choose a plan at your real summer usage and put your contract end date on the calendar.
Think of it as two separate jobs. Your retail electric provider (REP) sells you the electricity, sets your plan price and bills you. Oncor, the transmission and distribution utility (TDU), maintains the lines, reads your smart meter and repairs outages. Every provider relies on the same Oncor system, so a new provider won't change the reliability of your service.
During an outage, go straight to Oncor. You can reach Oncor 24/7 at 888-313-4747, text OUT to 66267, or report it on the Oncor outage page. For more on what Oncor charges and why, read our explainer on TDU delivery charges.
The best electric company in Round Rock for you is the one with the lowest cost at your usage and terms you can live with. Every plan below is in our Round Rock table, priced at 500, 1,000 and 2,000 kWh as of November 4, 2026.
High, steady usage of 1,000 kWh or more: 4Change Energy's Maxx Saver Value 12 and Frontier Utilities' Frontier Saver Plus 12 tie at 20.3¢, 7.4¢ and 13.4¢. The cancellation terms differ: $20 for each remaining month with 4Change, a flat $150 with Frontier.
Two years of price stability: Frontier Saver Plus 24 (21.3¢, 8.4¢, 14.5¢) comes in below Maxx Saver Value 24 (22.0¢, 9.0¢, 15.1¢) at all three usage levels, with a $200 cancellation fee.
Apartments and low usage: none of the plans in our Round Rock table suits you this month, since all of them start above 20¢ at 500 kWh. On Power to Choose, the three cheapest 12-month plans without a credit held between 11.8¢ and 12.4¢ at every usage level.
Green power: our Round Rock table has no 100% renewable plan this month. Power to Choose listed 43 fully renewable plans for Oncor addresses on November 4, and our reviews of Gexa Energy and Green Mountain Energy cover two providers built around renewable plans.
Whatever you lean toward, compare at least three plans at your own usage and open each EFL on the day you enroll to confirm the price and terms.
On a fixed-rate plan, your energy price stays the same for the full term, often 12, 24 or 36 months, so summer demand can't raise it. Ending the contract early can cost an early termination fee (ETF): 4Change's plans charge $20 per remaining month, while Frontier's charge a flat $150 on the 12-month plan and $200 on the 24-month plan. Oncor's delivery charges can still move during your term, because the PUCT sets them. Compare more fixed-rate electricity plans.
Variable plans carry no long-term contract, but the price can change with each billing cycle. On Power to Choose on November 4, variable plans for Oncor addresses ranged from 9.9¢ to 18.4¢ per kWh at 1,000 kWh. They fit a short stay before a move, and they're the riskiest choice heading into summer.
Prepaid plans run on a pay-ahead basis: you add money up front, get alerts as your balance drops, and skip the deposit and credit check. There are none in our Round Rock table this month. On Power to Choose, prepaid plans for Oncor addresses cost 16.5¢ to 17.9¢ per kWh at 1,000 kWh. Our no-deposit electricity guide goes through the options.
Renewable plans are backed by renewable energy credits, often from Texas wind and solar. On November 4, Power to Choose listed 43 of its 171 Oncor-area plans as 100% renewable. Explore green energy plans and read the renewable content line on the EFL.
Time-of-use plans price power lower at certain hours, often overnight or on weekends, which can work well for electric vehicle charging. Power to Choose listed six for Oncor addresses this month. Solar buyback plans pay or credit rooftop solar owners for power they push back to the grid, so compare the buyback rate, monthly fees and what happens to leftover credits.
Moving to a new provider is quick, and there's no gap in service.
Locate your ESI ID (Electric Service Identifier) on a recent bill. This number identifies your meter.
Compare plans at your real usage, choose one and sign up with your service address.
Pick a start date. Your new provider handles the handover with Oncor, with no visit to your home.
If you're in a contract, check when it ends. Under PUCT rules, switching no earlier than 14 days before the expiration date on your renewal notice means no early termination fee, and providers must send that notice at least 30 days before the contract expires. The PUCT electricity FAQ has the specifics.
If you're new to Round Rock, our guide to switching electricity providers in Texas also explains how to start service at a new address.
