Your electricity in zip code 75057 is delivered by Texas-New Mexico Power. Since this area is deregulated, you can choose your retail electricity provider while Texas-New Mexico Power maintains the power lines and handles outage restoration.
Lewisville residents in zip code 75057 are sitting in one of the most competitive electricity markets in Denton County. As part of Texas's deregulated energy market, this area is served by Texas-New Mexico Power (TNMP) for delivery infrastructure — but when it comes to choosing who generates and sells your electricity, you have real options. In March 2026, 49 retail electric providers are actively competing for your business across 215 available plans, with rates starting as low as 9.9¢/kWh. With a city population of over 111,000 and a median household income of $62,714, Lewisville's energy market reflects the broader Denton County growth story — and that competition is working in your favor.
The most competitive rate currently available in the 75057 zip code is 9.9¢/kWh, offered through the True Power TNMP 12-Month Fixed Residential plan from True Power. That's a significant discount compared to the market average of 15.0¢/kWh across all 215 plans — a gap of more than 5 cents per kilowatt-hour. For a typical Texas household using around 1,100 kWh per month, that difference can translate to $55 or more in monthly savings. Rates in this area are shaped by TNMP's regulated delivery charges, wholesale energy market conditions in ERCOT's North Zone, and the intense provider competition driving promotional pricing.
In 75057 right now, short-term plans (1–6 months) average 14.2¢/kWh — actually the most affordable average tier, making them an interesting option for renters, recent movers, or anyone expecting to reassess their situation soon. Medium-term plans (7–18 months) average 15.1¢/kWh, and long-term plans (19+ months) also average 15.1¢/kWh. The standout value, however, is the 9.9¢/kWh 12-month fixed rate from True Power — a medium-term contract that dramatically undercuts all averages. If you want price stability heading into summer 2026 and beyond, locking in a 12-month fixed plan now is a smart hedge against seasonal demand spikes.
With 49 providers and 215 plans available, the 75057 market is classified as highly competitive — and that's great news for consumers. Well-known names like Reliant Energy, Direct Energy, Shell Energy, and Champion Energy compete alongside value-focused providers like Cirro Energy, Frontier Utilities, and Payless Power. Renewable-focused options include Chariot Energy, Rhythm Energy, 4Change Energy, and Good Charlie, which together offer 40 green or renewable-energy plans. This diversity means you can prioritize price, contract flexibility, green energy, or customer service — and still find a competitive offer.
Regardless of which retail electric provider (REP) you choose, Texas-New Mexico Power handles the physical delivery of electricity to your home in 75057. TNMP's delivery charges are regulated by the Public Utility Commission of Texas and are identical no matter which provider you select — so switching providers never affects the reliability or safety of your service.

Lock in a fixed-rate plan before June: Lewisville's summer temperatures routinely reach 98°F or higher, driving peak wholesale electricity prices upward. Securing a 12-month fixed rate in April or May protects your budget through the hottest billing cycles of the year.
Verify your TDSP before enrolling: Residents in Lewisville's northern and western subdivisions may fall under CoServ Electric's territory rather than Oncor. Entering your full address — not just your zip code — on any comparison tool ensures you see only plans available at your specific location.
Explore free-nights plans if you work from home: Many Lewisville professionals now work remotely full or part-time, shifting heavy electricity use — computers, monitors, A/C — to daytime hours. A flat-rate or time-of-use plan with cheaper daytime pricing may outperform a free-nights structure for your profile.
Consider a bill-protection or average-billing rider during summer: Lewisville's August electric bills can spike dramatically due to A/C runtime. Some REPs offer average-billing programs that smooth costs across 12 months, preventing the budget shock of a $250+ August bill after a mild-weather spring.
Take advantage of smart thermostat incentives: Several REPs serving Lewisville offer $50–$100 rebates or bill credits for enrolling your Nest or Ecobee thermostat in a demand-response program. These programs briefly raise your setpoint during grid peak events, often saving both you and the grid meaningful energy.
