TNMP profile

InsideTNMP.

Texas-New Mexico Power Company (TNMP) is one of the smaller Texas competitive-market TDUs, with a patchwork of service territories — parts of DFW (The Colony, Coppell partial), Brazoria County, the Gulf Coast around Texas City and Galveston-adjacent areas, and several West Texas pockets. Owned by PNM Resources, headquartered in Albuquerque.

Reliability & outage history

Patchwork service territory makes statewide reliability metrics less informative — local reliability varies significantly across TNMP's geographically separated zones. Gulf Coast zones have hurricane exposure, DFW zones have severe-thunderstorm exposure.

Notable facts

  • ·TNMP delivery charges run slightly higher than the larger TDUs — roughly 5.3¢/kWh plus a $7.85 monthly meter charge.
  • ·Smaller call center capacity than Oncor or CenterPoint — wait times during major events can be longer.
  • ·PNM Resources also owns the regulated New Mexico utility — different from the Texas competitive market structure, occasional cross-pollination of operational practices.
  • ·Coppell and The Colony residents are often surprised they're on TNMP rather than Oncor — service maps are not always intuitive in the DFW pocket.

TNMP questions

TNMP FAQ.

What does TNMP actually do?

+

Texas-New Mexico Power owns and maintains the wires, poles, transformers, and meters across pockets across texas — north, houston-area, gulf coast. They don't sell you electricity — they deliver whatever your retail provider buys from the wholesale market. Their delivery charge (set by the PUCT) is identical across every provider's plan you see.

Can I switch off TNMP?

+

No. Your TDU is geographic — it's determined by your address, not your choice. What you can switch is your retail provider, which changes who bills you and what per-kWh rate you pay. The wires, the meter, and the outage line all stay with TNMP.

What is TNMP's outage number?

+

Call 1-888-866-7456 for any power-out, downed-line, or meter emergency. Don't call your provider — they can't dispatch crews. Save this number in your phone before you need it.

Why does TNMP show up on my bill?

+

Every Texas provider passes the TDU delivery charge straight through to your bill, usually as a separate line item. On TNMP territory that's roughly 5.3c/kWh plus a $7.85 monthly meter charge. It's not negotiable and it's identical across providers — when one plan looks cheaper, the difference is in the energy charge, not the delivery fee.
