Question 1

What's the cheapest electricity rate in Round Rock?

Accepted Answer

It shifts as providers update their plans, so the live ranking on this page always reflects today's lowest rate in Round Rock — pulled fresh from the market. As a rule of thumb, anything below the city average shown above is competitive.

Question 2

Can I really pick any provider in Round Rock?

Accepted Answer

Yes. Round Rock sits in a deregulated zone, so any retail electric provider (REP) certified to serve your TDU can sell you power. ONCOR ELECTRIC DELIVERY COMPANY delivers it regardless of which one you pick.

Question 3

Why do plans look cheaper in ads than on my bill?

Accepted Answer

Most ads quote the energy charge alone. Your real bill stacks the supplier's energy charge, the TDU delivery charge, and a flat monthly base fee. Always compare the all-in average at your actual monthly usage on the EFL.

Question 4

Fixed-rate vs. variable — which should I pick?

Accepted Answer

Fixed-rate locks the per-kWh charge for the contract length — predictable, easier to budget. Variable floats with the wholesale market — cheaper when forwards are soft, painful during summer peaks. Most households pick fixed for the certainty.

Question 5

How long does it take to switch providers?

Accepted Answer

Most switches take 1–3 business days from the moment you sign. There's no service interruption — the same TDU keeps the power flowing, only the billing entity changes.

Question 6

Is green energy actually more expensive?

Accepted Answer

Not always. Several 100% renewable plans in our list price within a fraction of a cent of the cheapest brown-power plans, because Texas wind and solar capacity has driven down the renewable energy credit (REC) cost.

Question 7

What happens if my fixed-rate contract ends?

Accepted Answer

Your plan rolls onto a month-to-month variable rate that's almost always higher — sometimes meaningfully. Set a calendar reminder ~30 days before expiry and re-shop the market.
