Oncor Electric Delivery
Round Rock is technically in the Austin metro but — unlike Austin proper — sits on Oncor territory and is fully deregulated. Residents here can shop 200+ retail plans just like Dallas. If you live in Round Rock and haven't shopped your electricity plan, you're leaving money on the table that Austin city-limits residents can't even access.
Questions Round Rock residents ask us.
Yes. Most retail electricity service in Round Rock is deregulated. You pick the retail provider and Voltcheckr helps you find the cheapest plan for your actual usage.
Round Rock homes average around 1,100 kWh per month at an effective rate near 13.6¢/kWh, which works out to about $150/month. Voltcheckr calculates your exact bill against 200+ plans so you know where you actually stand.
Pick a plan on Voltcheckr, click Switch, and your new provider handles the cancellation of your old plan automatically. No calls, no paperwork, no double billing. Your new rate typically starts within 1–3 business days.
If you're inside a fixed-term contract, early termination fees (ETF) typically run $150–$295. Voltcheckr surfaces the ETF on your current plan and subtracts it from your first-year savings so you see the real break-even. If you're in the last 14 days of your contract, you can switch ETF-free.
Rates change daily. Upload your bill (or enter your ZIP + home size) and Voltcheckr shows you the real-time cheapest plan, refreshed nightly from Power to Choose.
