About WattaWatt: how we price Texas electricity plans

Texas electricity plans advertise one price, measured at exactly 1,000 kWh in a month. Real homes use 400 kWh in March and 1,800 in August, and bill credits, tiers and base charges all react to that swing. The gap between the price on the ad and the price on the bill is where most of the money in this market is made. WattaWatt closes it: drop in a bill, or type 12 monthly numbers, and every plan in your area is priced on your year and ranked by what it would cost you.

How a plan is priced

For each plan we simulate 12 monthly bills from the numbers on its Electricity Facts Label: the energy charge or tiers, the base charge, any bill credit or minimum-usage fee, and your delivery utility’s current charges. We add the 12 up and sort. Plans of 12 months or longer are ranked first, because they hold that price for the whole year; contracts of 3 to 9 months are priced too and shown apart, since nothing says what the months after them cost. The how-it-works page walks through an example.

Every price on this site is an estimate. Taxes and the regulatory fees that aren’t on the label are left out, so real bills run a little higher on every plan alike. When a label and our model disagree, the label wins: check it before you enroll. Every plan links to its label.

Where the plans come from

Every week we take the state’s own list, Power to Choose, and the providers’ own websites, which usually sell more plans than they post on the state site, and collect every fixed-rate plan sold in each of the six delivery areas. Then we open each plan’s Electricity Facts Label and read the numbers from it, and check that our model reproduces the three average prices the label publishes. Right now that’s 1,703 plans from 47 providers, every one checked against their label, most recently on November 4, 2026. Another 155 time-of-use plans and 88 variable-rate plans are listed with their labels’ numbers but not ranked; the next section says why. The whole list is on Plans we track, with the label numbers for each.

Delivery charges come from each utility’s published residential rates and are checked against the labels the same way; the current ones for all six utilities are on one page. We never log in anywhere, never submit anyone’s details, and respect the sites we read.

What we list but don’t rank, and what we leave out

Two kinds of plan are in the catalog with a “Not ranked” badge instead of a place in the order. Time-of-use and free-nights plans, because pricing them honestly needs your hourly usage, not your monthly totals: a free-nights plan charges more by day, and delivery is billed on every kWh, free hours included, so whether it wins depends on a split your bill doesn’t show. And variable-rate plans, because their price next month isn’t knowable; we show this month’s. We’d rather list them than rank them wrong, and listing them means you can check that we have a provider’s whole lineup.

Left out altogether: plans that need solar panels, a home battery, an electric vehicle or a particular thermostat; plans limited by age; and any plan whose label doesn’t add up when we check it.

How we make money

It doesn’t, yet. No electricity provider pays WattaWatt anything, for a listing or a sign-up. If that changes, plans that pay us will be labeled wherever they appear, and the fee will never change where a plan ranks: the order is the arithmetic. The full terms are on the disclosures page.

Your bill

An uploaded bill is read for its usage history and discarded; it’s never stored. The 12 numbers, your ZIP code and, if you give them, your contract end date and a reminder email are kept with your results link. The privacy policy says exactly what’s kept and for how long.

Who runs it

WattaWatt is an independent comparison service. It isn’t an electricity provider, a delivery utility or an agency of the state, and it isn’t affiliated with any of them. The operating company is on the disclosures page. Found a number that’s wrong? Write to support@wattawatt.com with the plan name and we’ll check the label again. Complaints about the service go through the complaints page.
