FAQ
- How long does it take to switch providers in Round Rock?
- Standard meter-read switching: 1-3 business days on the Oncor grid. Same-day if you order before the provider's cutoff (typically 4-5 PM Central). No service interruption — same wires, same meter, new bill.
- Will my power go out during a switch?
- No. Oncor keeps your meter energized through the switch. The only thing that changes is who reads the meter and who bills you.
- What's the average rate in Round Rock?
- The live plans we list on the Oncor grid average 15.2¢/kWh at 1,000 kWh. The cheapest start around 7.0¢/kWh, so shopping below the average is realistic — compare current plans for your exact ZIP to see what's live today.
- When is the best time to switch?
- Within the last 14 days of your current contract (no early termination fee per Texas law) or right after a rate hike on a variable plan. Don't wait for auto-renewal — providers default expiring contracts to month-to-month variable rates that are typically 30-50% higher.
- What if I have an early termination fee?
- Crunch the math: ETF amount vs. monthly savings × months remaining. If switching saves you $30/month and your ETF is $150 with 8 months left, the ETF pays itself off in 5 months and you net $90.
