A real Dallas–Fort Worth example

Advertised 6.9¢ on the ad.15.1¢ on the bill.

Texas plans advertise one price, measured at exactly 1,000 kWh a month. This plan’s low price depends on a $125 bill credit that only arrives in months you use 1,000 kWh or more.

This Carrollton home got there in 4 of 12 months. The rest of the year it paid the full rate, so a flat plan advertised at 12.0¢ came out $344 cheaper.

WattaWatt does this math for every plan, using the usage on your own bill.

Why WattaWatt, not another comparison site

Every other site ranks plans by the price at exactly 1,000 kWh a month, which is the one number providers design their plans around. We rank them by what your home would pay over a year, and we show the bills. On the Carrollton home above, the plan at the top of a 1,000 kWh sort would have cost $344 more.

Questions people ask

How does WattaWatt make money?

It doesn't, yet. Using WattaWatt costs you nothing, and no electricity provider pays us, for a listing or a sign-up. If that changes, plans that pay us will be labeled, and the money will never affect the ranking.

Which areas do you cover?

Everywhere in Texas where homes choose their own electricity provider: Dallas–Fort Worth (Oncor), Houston (CenterPoint Energy), Corpus Christi, Laredo and the Rio Grande Valley (AEP Texas Central), Abilene and San Angelo (AEP Texas North), TNMP's towns, and Lubbock. Your ZIP code tells us which utility delivers your power. Cities with their own utility, such as Austin and San Antonio, don't have a choice to make.

Why do you need 12 months of usage?

Many Texas homes use two or three times as much electricity in summer as in spring. A full year captures both, and that's what decides whether a bill credit or a tiered rate works in your favor.

What if I'm still under contract?

Tell us when it ends and what the cancellation fee is. We'll compare switching now with waiting, and we can remind you 45 days before it ends so you don't roll onto a month-to-month rate.

How accurate are the estimates?

We use each plan's Electricity Facts Label and your delivery utility's published charges. Taxes and a few small fees aren't included, so real bills run a little higher, for every plan alike.

Do you sign me up for a plan?

No. When you choose a plan, we link you to the provider's own page to enroll.
