Round Rock Electricity FAQ
Common questions about electricity rates, plans, and providers in Round Rock, Texas.
How does electricity deregulation work in Round Rock?
In Round Rock, electricity delivery and supply are separated. AEP Texas handles the wires and infrastructure, while you pick from competing suppliers (REP (Retail Electric Provider)s) for your actual electricity. This competition is regulated by the Public Utility Commission of Texas (PUCT).
What is the cheapest electricity rate in Round Rock right now?
Right now, Round Rock rates start at 7.1¢/kWh for 1,000 kWh usage, offered by AP GAS & ELECTRIC (TX) LLC (SimpleSaver 12 - 7.10¢). With 183 plans on the market, the average is 13.75¢/kWh. That’s a 48% spread between the cheapest and the average.
What is the average monthly electric bill in Round Rock?
A typical Round Rock household using 1,000 kWh pays around $138/month at the average rate of 13.75¢/kWh. Your bill will vary with seasonal usage patterns — summer AC and winter heating drive the biggest swings.
Who delivers electricity in Round Rock?
AEP Texas handles all electricity delivery in Round Rock — the physical infrastructure, meter reading, and outage response. Your choice of supplier only affects who generates and bills for the supply portion.
How do I switch electricity providers in Round Rock?
Switching is straightforward: compare plans, choose a REP (Retail Electric Provider), and sign up. The new supplier coordinates with AEP Texas automatically. Expect the switch to take 1–2 business days. There’s no physical work needed and no outage.
What happens when my contract expires?
Most suppliers move you to a month-to-month variable rate after your fixed term ends. This is usually higher than your locked-in rate. Set a reminder to compare plans before your contract expires.
How do Round Rock business electricity rates work?
Round Rock business electricity is priced differently from residential. Your rate depends on peak demand (kW), total consumption (kWh), and contract term. Request quotes from multiple REP (Retail Electric Provider)s to find the most competitive offer.
Who handles power outages in Round Rock?
AEP Texas. Your electricity supplier has no role in outage response — that’s always handled by the delivery company.
