Lewisville, in southern Denton County, is split between two delivery utilities: TNMP serves most of the city and Oncor the rest. Both are in the choice market, so Lewisville homes pick their own provider either way. Neighboring Denton runs its own municipal utility, so Denton residents can’t shop.
For a typical Lewisville home using about 1,000 kWh a month, the cheapest plan that holds its price all year is Speedy 12 from Express Energy, at about $1,389 for the year (11.6¢ per kWh all-in). The plan with the lowest advertised price, SimpleSaver 12, would cost the same home $679 more.
Price every plan on your own 12 months
The tables below use three typical homes. Your home isn’t typical. Drop in a bill from your Lewisville address, or type your 12 monthly kWh, and we’ll rank every plan by what you’d actually pay.
Plans advertise a price at exactly 1,000 kWh a month. A Lewisville home uses far less than that in spring and far more in August, so we price each plan month by month on a year with a real summer peak, for a small, a typical and a large home.
About 500 kWh a month: a one- or two-bedroom apartment, or a small house with gas heat. 6,001 kWh over the year, with a Lewisville summer peak.
| Plan | Term | Advertised at 500 kWh | Real price | Per year |
|---|---|---|---|---|
 Speedy 12 Express Energy | 12 mo | 12.3¢ | 12.3¢ | $740 lowest |
 Basic 12 Veteran Energy | 12 mo | 12.3¢ | 12.3¢ | $740 +$0 |
 No Bull 12 Energy Texas | 12 mo | 13.9¢ | 13.9¢ | $834 +$94 |
The cheapest-looking plan loses here. SimpleSaver 12 advertises 8.9¢ at 1,000 kWh, the lowest of any plan, but this home would pay 22.2¢ per kWh on it: $589 more over the year than Speedy 12. It ranks #179 of 208.
Contracts under a year are ranked apart. Plans of 12 months or longer are ranked above, because they hold their price for the whole year. The cheapest shorter contract, No Bull 3 (3 months), would cost about $750 if its price held for 12 months, which it doesn’t promise to.

Estimates, as of November 2026. We simulate 12 monthly bills for each of the 265 plans we track from 40 providers, using each plan’s Electricity Facts Label and TNMP’s published delivery charges, on the three usage profiles above. Taxes and fees that aren’t on the EFL are left out, so real bills run a little higher for every plan alike. Listed but not ranked: 26 time-of-use plans ("free nights" and the like), priced by the time of day or week, which a monthly bill doesn't show; and 13 variable-rate plans, with a price that can change every month, so a year ahead can't be priced from today's rate. They’re on Plans we track with their labels. Prices change; check the EFL before enrolling.
A good rate is an all-in price on a year of your own usage. On the plans we track this month, the lowest all-in price is about 12.3¢ per kWh for a small Lewisville home, 11.6¢ for a typical one and 11.2¢ for a large one. Smaller homes pay more per kWh because TNMP’s fixed monthly charge, and any base charge, is spread over fewer kWh. An advertised price below those numbers usually depends on a bill credit or a tier that a real year doesn’t fully earn.
Every home in Lewisville pays TNMP the same delivery charge, whichever retail provider sells the electricity: $7.56 a month plus 7.771¢ per kWh (rates effective October 1, 2026). That’s about $46.42 in a 500 kWh month, $85.27 at 1,000 kWh and $162.98 at 2,000 kWh.TNMP’s charges change a few times a year; the prices on this page include the current ones.
Lewisville is in Denton County. ZIP codes 75057, 75067 and 75077. The prices on this page are for TNMP addresses. If your bill names Oncor as the delivery company, the same plans cost a little less, because Oncor’s delivery charges are lower; type your ZIP code on the home page and pick Oncor.
For a typical home using about 1,000 kWh a month, the cheapest plan of 12 months or longer we track as of November 2026 is Speedy 12 from Express Energy: about $1,389 for a year, or 11.6¢ per kWh with TNMP delivery included. The plan with the lowest advertised price, SimpleSaver 12 at 8.9¢, costs about $679 more over the year once it's priced on real monthly usage. The order changes with how much you use, so price the plans on your own 12 months before choosing.
Judge a rate all-in, on a year of your own usage, not by the advertised price. On the plans we track, the cheapest all-in price is about 12.3¢ per kWh for a small home (500 kWh a month), 11.6¢ for a typical home (1,000 kWh) and 11.2¢ for a large one (2,000 kWh). Small homes pay more per kWh because TNMP's monthly charge and any base charge are spread over fewer kWh.
TNMP. It owns the poles, wires and meters, restores power after outages, and charges every home the same delivery rate no matter which retail provider you choose: $7.56 a month plus 7.771¢ per kWh (rates effective October 1, 2026), about $85.27 in a 1,000 kWh month. Your retail provider collects it on TNMP's behalf. The prices on this page are for TNMP addresses. If your bill names Oncor as the delivery company, the same plans cost a little less, because Oncor’s delivery charges are lower; type your ZIP code on the home page and pick Oncor.
Comparison sites put the average Texas home somewhere between about 900 and 1,200 kWh a month, but the average hides the swing: summer months often run two to three times winter ones. Our typical-home profile uses 12,000 kWh over a year, from 450 kWh in its lowest month to 1,988 kWh in its highest. That swing is what decides whether a bill-credit or tiered plan pays off.
Yes, in two cases. Texas rules let you switch in the last 14 days of a fixed-term contract without an early termination fee, and your provider has to send you a notice before the contract ends. You also owe no fee if you're moving out and give the provider proof of your move. Otherwise the fee is on the plan's Electricity Facts Label; tell WattaWatt your contract end date and fee, and it works out whether switching now or waiting costs less.
Because a monthly bill can't price one. Listed but not ranked: 26 time-of-use plans ("free nights" and the like), priced by the time of day or week, which a monthly bill doesn't show; and 13 variable-rate plans, with a price that can change every month, so a year ahead can't be priced from today's rate. They are on our plans page with their labels, marked "Not ranked", so you can see the whole market; we'd rather not rank them than rank them wrong. A free-nights plan charges more in the daytime, and delivery charges apply to every kWh, free hours included, so for most homes it costs more than a plain fixed-rate plan unless well over half of their use falls in the free hours. Smart Meter Texas shows your own 15-minute usage if you want to check your split.
