Discover how Texas-New Mexico Power handles electricity delivery, outage restoration, and delivery fees in your deregulated Texas service area.
Key Takeaways
- Texas-New Mexico Power (TNMP) does not sell electricity; it is the utility company that maintains the grid, poles, and wires for over 280,000 homes and businesses across Texas.
- You will need to compare and select a Retail Electric Provider (REP) to set up your actual electricity plan and handle your monthly billing.

If you live in a deregulated region of Texas, setting up your electricity can feel a little complicated at first glance. While you have the freedom to shop around for the best electricity rate, the physical delivery of that power is handled by a single utility company based on your geographic location. For hundreds of thousands of Texans, that dedicated company is Texas-New Mexico Power. Whether you are moving into a new home and need to turn on the lights, trying to understand an unexpected delivery fee on your monthly bill, or looking for the fastest way to report a power outage, we have gathered everything you need to know about navigating your TNMP service smoothly.
What Is Texas-New Mexico Power (TNMP)?

Texas-New Mexico Power, commonly known as TNMP, is a transmission and distribution utility (TDU) operating within the Electric Reliability Council of Texas (ERCOT) grid. As a wholly owned subsidiary of TXNM Energy, TNMP has a long history of reliable infrastructure management. They currently provide service to over 280,000 homes and businesses across Texas and employ more than 400 people throughout their 20-plus community locations.
It is crucial to understand that TNMP does not sell electricity. While you get to select your own electricity seller (a Retail Electric Provider or REP), TNMP handles the delivery of that energy behind the scenes. As a TDU, they are strictly responsible for maintaining the physical infrastructure that brings power safely to your home — including the poles, wires, substations, and electric meters. They are also the dedicated team that dispatches crews to restore service following severe weather or unexpected grid emergencies.
TNMP Coverage Area and Service Map
TNMP’s certified service territory lies entirely within the state of Texas. Rather than serving one massive, continuous block of the state, their delivery footprint is uniquely divided into three distinct regions. If you live in any of these territories, you will see a specific line item for TNMP delivery charges on your monthly bill.
Here is a quick look at some of the major municipalities within the TNMP service area categorized by region:
- North Texas: Lewisville, Flower Mound, and Glen Rose
- West Texas: Pecos, Fort Stockton, and Kermit
- Gulf Coast: Angleton, Freeport, Clute, Alvin, Friendswood, and La Marque
Understanding TNMP Delivery Charges and TDSP Fees
A common point of confusion for new Texas residents is understanding exactly how they are billed for electricity. Even though TNMP maintains your lines and meters, you will not receive a direct bill from them. Instead, your chosen Retail Electric Provider automatically includes the TNMP delivery charges — often referred to as TDSP fees — on your monthly statement and passes those funds along to the utility on your behalf.
These charges are mandated and regulated by the Public Utility Commission of Texas (PUCT). They are standard for every residential customer in the service area, meaning you cannot avoid or negotiate them by switching REPs. Currently, consumers pay these delivery fees to help fund necessary grid modernization, storm hardening, and improved outage response infrastructure across the expanding TNMP footprint.
| Charge Type | Current 2026 Rate | How It Works |
|---|---|---|
| Fixed Monthly Base Charge | $7.85 per month | A flat fee applied to every billing cycle, regardless of how much electricity you use. It covers basic customer service, metering systems, and account administration. |
| Volumetric Charge | 6.4665¢ per kWh | A variable cost based on your actual energy consumption. The more kilowatt-hours (kWh) you use, the higher this portion of the delivery charge will be. |
Compare Texas-New Mexico Power Electricity Rates
Because TNMP operates in a deregulated electricity market and strictly handles power delivery, you have the freedom to shop around and choose the Retail Electric Provider that fits your budget and lifestyle. Your REP determines your energy supply rate, the length of your contract, and any special perks like free weekend usage or renewable energy add-ons.
If you are searching for Texas New Mexico Power electricity plans, you are actually looking for plans offered by third-party suppliers who service the TNMP grid. Here is a comparison of estimated rates from top REPs currently operating in TNMP territory:
| Provider Name | Plan Name | Term Length | Estimated Rate (¢/kWh) |
|---|---|---|---|
| TXU Energy | Smart Edge | 12 Months | 14.5¢ |
| Gexa Energy | Eco Saver Plus | 24 Months | 12.2¢ |
| Reliant Energy | Conservation Plan | 12 Months | 15.1¢ |
| 4Change Energy | Maxx Saver Select | 12 Months | 11.9¢ |
| Direct Energy | Live Brighter | 36 Months | 13.8¢ |
How to Switch Providers in TNMP Territory
If your electricity bills are getting too high, lowering your energy supply rate is the fastest way to save money. Since TNMP’s delivery charges are unavoidable, choosing a cheaper REP is the smartest move you can make. Switching providers is entirely seamless, and you will not experience any interruption in your power supply during the transition.
Here is how to switch providers in three easy steps:
- Locate your ESI ID: Grab your most recent electricity bill and locate your Electric Service Identifier (ESI ID). This unique 22-digit number tells your new provider exactly which meter TNMP needs to direct power to.
- Compare rates and read the EFL: Use a trusted comparison tool to search for rates by your zip code. Before signing up for any plan, you must check the Electricity Facts Label (EFL). The EFL is a legally required document that outlines exactly what you will pay at 500, 1,000, and 2,000 kWh of usage. Checking this document prevents you from falling victim to hidden tiered usage fees or bill credit traps.
- Sign up with your new REP: Once you find a plan with a favorable EFL, enroll online or over the phone. Your new provider will handle the entire transition process automatically by notifying TNMP and your previous supplier.
TNMP Outage Map and Emergency Contacts
When the lights go out, getting accurate information and reporting the issue quickly is your top priority. Since TNMP maintains the local power grid, they are your direct point of contact during an outage, regardless of which retail provider you buy your electricity from.
If you suspect a power outage or spot a dangerous downed power line in your area, you can take the following steps:
- Check the Texas New Mexico Power outage map: Visit the TNMP outage map online for real-time updates, affected coverage zones, and estimated restoration times for your neighborhood.
- Call the 24/7 emergency hotline: Dial 1-888-866-7456 to report an outage or check on the status of a repair. Always call this number immediately if you see a direct hazard like a sparking transformer or a downed wire.
- Report the outage online: Use their online reporting form to quickly notify dispatchers of a localized issue without waiting on hold.
- Check social media: Follow their X account (formerly Twitter) @TNMPOne, where they frequently post critical updates during severe weather events or widespread grid issues.
Deals, Discounts, and Energy Efficiency Rebates
TNMP offers an extensive catalog of incentives aimed at lowering usage and improving overall grid efficiency. Because your delivery service is independent of your REP choice, you remain fully eligible for these programs no matter who you buy your power from. While TNMP does not directly generate electricity, reducing home consumption indirectly lowers demand on the entire grid and saves you money.
Key energy-saving programs include:
- Low-Income Weatherization: This program assists eligible households with high-impact upgrades like enhanced insulation, high-efficiency HVAC tune-ups, and the installation of smart thermostats to drastically cut winter heating and summer cooling costs.
- High-Performance Homes: Geared toward new construction, this program provides incentives for builders and buyers who invest in ENERGY STAR-certified homes that exceed standard building codes.
- The COMPASS Program: The Commercial Partners Achieving Specialized Solutions (COMPASS) initiative targets schools, local governments, and large commercial customers. It offers financial incentives — such as $400 per kW saved — for qualifying efficiency upgrades.
Additionally, TNMP’s grid infrastructure is fully compatible with solar net metering. If you install residential solar panels and pair them with an eco-conscious alternative buy-back plan from your REP, your home can send excess energy back to the grid for a bill credit. By leveraging TNMP’s energy efficiency incentives and renewable capabilities, you can drastically reduce your environmental footprint while keeping your monthly costs manageable.
Texas-New Mexico Power Reviews and Ratings
When searching for Texas New Mexico Power reviews online, it helps to understand exactly what customers are evaluating. Because TNMP does not handle billing or sell energy plans, the majority of relevant feedback focuses strictly on grid reliability, community communication, and response times during outages.
Across the Better Business Bureau (BBB) and local community forums, customer sentiment generally highlights TNMP working efficiently in the background during routine operations. Following major Texas storm events, some residents occasionally express frustration with prolonged restoration times, though TNMP’s dedicated local crews frequently receive praise for working in dangerous conditions to repair downed lines.
A significant portion of negative reviews directed at TNMP actually stem from billing confusion regarding rates or termination notices. You should direct those financial concerns directly to your Retail Electric Provider. However, if you have an unresolvable dispute regarding utility infrastructure, smart meter accuracy, delivery standards, or property damage, you can escalate the issue by filing a formal complaint directly with the Public Utility Commission of Texas (PUCT).
Managing Your TNMP Service Efficiently
Texas-New Mexico Power is a reliable, established utility handling the heavy lifting of electricity delivery for residents across North, West, and Gulf Coast Texas. While you do not get to choose TNMP as your utility — that is determined strictly by your home’s address — you do hold the power to control your overall electricity costs.
Because TNMP delivery charges are standardized and unavoidable, your best strategy is to proactively compare REPs. By carefully evaluating different energy plans, thoroughly reading the Electricity Facts Label, leveraging TNMP’s robust energy efficiency rebates, and minimizing your household consumption, you can secure the best possible rate and ensure your utility bills stay predictable all year long.
