Who delivers electricity in Lewisville?
Lewisville is a good example of why checking your address matters. Texas-New Mexico Power (TNMP) serves Lewisville, and Oncor delivers to some nearby areas in the same part of Denton County, so the delivery company can depend on your street. Both are wires companies rather than plan sellers, so you choose a retail electric provider either way. We confirm which delivery utility applies, then compare fixed-rate plans that fit your usage.
ImportantDo not assume your delivery utility from the city name. Confirm by ZIP or address, since it determines who to call for an outage.

FAQ
Frequently asked questions
Is Lewisville served by Oncor or TNMP?
Lewisville is generally served by TNMP, and nearby areas may be served by Oncor. Enter your ZIP or call us to confirm your address.
Does the delivery utility change which plans I can get?
Retail plans are offered by competing providers and availability can vary by delivery area. We show you what applies to your address.
Who do I call if power goes out in Lewisville?
Call your delivery utility, meaning TNMP or Oncor depending on your address. Your retail provider cannot restore power.
Can I switch providers without losing service?
Yes. Your power keeps flowing through the same delivery lines. Only the retail provider and rate change.
What is a TDSP, and who is mine in Lewisville, Texas?
A TDSP (Transmission and Distribution Service Provider) is the regulated utility that owns the poles, wires and meters, reads your meter and restores power after an outage. It does not sell you an electricity plan and its delivery charges are the same whichever retail provider you choose. Your TDSP depends on your service address — in some areas more than one utility serves the same city — so confirm it by ZIP code or call us for a free check.
What is a retail electric provider (REP)?
A retail electric provider (REP) is the licensed company that sells you the electricity itself: it sets the rate per kWh, the contract term and the fees on your plan, and it bills you. In the ERCOT market you can shop and switch between REPs freely, while your TDSP keeps delivering the power, so switching never means new wires, a new meter or a service interruption.
