Texas-New Mexico Power (TNMP) serves a unique non-contiguous set of communities across Texas, including parts of the Dallas-Fort Worth suburbs, communities in the Gulf Coast area of Brazoria County, and scattered North Texas towns. TNMP's territory is smaller and less geographically concentrated than other Texas TDSPs, but the same deregulation rules apply — you can choose your retail electricity provider.

Important: Texas-New Mexico Power (TNMP) is your TDSP (Transmission and Distribution Service Provider) — the company that delivers electricity to your home through its grid infrastructure. TNMP does not sell electricity plans. Licensed retail electricity providers compete for customers in the TNMP territory.

TNMP Delivery Charges

TNMP's delivery charges are regulated by the Texas PUC. They include a fixed monthly base charge and a per-kWh delivery fee, and they apply uniformly in TNMP territory regardless of retail provider choice.

TrueBill includes TNMP delivery charges in every plan estimate. Many comparison sites show only the energy supply rate, which understates what you actually pay. The monthly cost you see on TrueBill already includes both the energy charge and the TNMP delivery fee.

Current TNMP Residential Delivery Charges

TNMP delivery charges have both fixed and usage-based components. All amounts are regulated by the Texas PUC and are identical regardless of which retail provider you choose.

As stated on 137 active plan Electricity Facts Labels captured through July 21, 2026. Delivery rates change only with PUC-approved tariff updates; the EFL for any plan you enroll in is the authoritative source.

Recent TNMP Delivery Charge Updates

TNMP files periodic rate adjustments with the PUCT. As a smaller utility, comprehensive rate cases occur less frequently than at larger TDSPs, but Distribution Cost Recovery Factor (DCRF) and Transmission Cost Recovery Factor (TCRF) adjustments follow the standard PUCT regulatory schedule. Current tariff rates are published at tnmp.com.

TNMP owns and operates electrical transmission and distribution infrastructure in its service areas. Like all Texas TDSPs, TNMP does not sell electricity plans; licensed retail providers compete for customers on TNMP's grid across both its North Texas and Gulf Coast clusters.

TNMP Service Territory

TNMP serves two geographically separate clusters of Texas communities. The North Texas cluster includes portions of DFW suburbs and surrounding towns: parts of Lewisville, parts of Denton, Stephenville (Erath County), Mineral Wells (Palo Pinto County), and Granbury (Hood County). The Gulf Coast cluster covers communities in Brazoria County south of Houston, including Clute, Alvin, Lake Jackson, and Angleton. These two areas share no geographic border — they are operated under the same TNMP TDSP regulatory umbrella but are physically separate grid networks with different infrastructure profiles.

TNMP Grid Infrastructure

TNMP is a subsidiary of PNM Resources (acquired by Avangrid, a subsidiary of Iberdrola, completing in 2023). Despite being smaller than Oncor or CenterPoint, TNMP operates under the same PUCT regulatory framework and the same ERCOT market rules. TNMP's Texas operations are separate from its New Mexico operations, which serve different communities under New Mexico utility regulation. Texas customers interact only with the Texas TDSP operations managed under ERCOT.

Frequently Asked Questions About TNMP

What is TNMP (Texas-New Mexico Power)?
TNMP is the TDSP for a collection of communities across two separate Texas regions — parts of the DFW suburbs and surrounding towns, and the Gulf Coast Brazoria County cluster. They deliver electricity through their infrastructure but do not sell plans. Licensed retail electricity providers compete for customers in TNMP territory.
How do I know if I'm in the TNMP service area?
The easiest way is to enter your ZIP code on TrueBill. TNMP serves a scattered set of communities — even within partially-served cities like Lewisville and Denton, some addresses are in the TNMP territory and others are in Oncor territory. Your electric bill will list your TDSP, or you can call your current retail provider to confirm.
Who do I call for a power outage in a TNMP area?
Call TNMP at 888-866-7456 to report power outages. You can also report at tnmp.com. Your retail provider cannot restore power in TNMP areas.
Why does TNMP serve disconnected parts of Texas?
TNMP's current territory reflects historical utility franchise agreements that predate deregulation. Texas municipalities and utility districts historically assigned service territories to utilities before the 1999 Senate Bill 7 created the deregulated ERCOT market. TNMP retained its franchise areas — which happened to be non-contiguous — when the deregulated market was formed.
Does TNMP also serve New Mexico?
Yes, TNMP is a subsidiary of PNM Resources, which also operates New Mexico Public Service Company (PNM) serving New Mexico communities. However, the Texas and New Mexico operations are entirely separate. TNMP's Texas customers are served under ERCOT and PUCT regulation; the company name reflects its original combined footprint but the Texas TDSP portion operates independently.
Are TNMP delivery charges higher than other TDSPs?
TNMP's fixed monthly base charge is typically higher than Oncor's, which can make delivery costs at lower usage levels relatively more expensive on a per-kWh basis. However, the per-kWh delivery rate is competitive with other TDSPs. TrueBill includes TNMP delivery charges in all plan estimates for TNMP addresses so you can compare all-in costs.
Can I switch electricity providers in the TNMP area?
Yes. TNMP's entire Texas service territory is within the deregulated ERCOT market. You can choose any licensed Texas retail electricity provider. Switching takes 1–3 business days and causes no service interruption. TNMP's delivery charges remain the same regardless of which provider you choose.
