About the Texas-New Mexico Power (TNMP)
Texas-New Mexico Power (TNMP) is a utility company that delivers electricity to homes and businesses across Texas. Founded over 80 years ago, TNMP is a transmission and distribution utility (TDU), which means they’re responsible for maintaining the poles, wires, and infrastructure that bring electricity to your door, not selling you the electricity itself. Even though they don’t sell electricity plans, they play a critical role in keeping the lights on, restoring power during outages, and ensuring reliable service across their territory. TNMP serves more than 260,000 customers across small towns and rural areas of Texas, including parts of North, West, and Gulf Coast regions.
TNMP Coverage Areas
TNMP provides electric delivery service to over 100 communities in Texas, including areas near:
- North Texas: Lewisville, Flower Mound, Glen Rose
- West Texas: Pecos, Fort Stockton
- Gulf Coast: Angleton, Freeport, Clute
If you live in a TNMP service area, you’ll see their name on the “TDU charges” section of your electricity bill, regardless of which retail electric provider (REP) you choose.
Choosing a Retail Electric Provider (REP)
In Texas’s deregulated electricity market, TNMP handles delivery, but you get to choose your electricity seller. This freedom can be great—but also a little overwhelming. Let’s break it down:
Why Choose a REP?
Choosing a REP gives you the power to pick a plan that matches your priorities, whether it’s saving money, supporting renewable energy, or locking in a stable rate. While TNMP ensures the power gets to your home reliably, your REP determines:
- Your electricity rate
- Contract length (month-to-month or multi-year)
- Perks like free nights or weekends
- Renewable energy options
