TNMP delivery charges and where TNMP delivers
TNMP delivers electricity to 237,930 homes in Texas but sells none: residential customers buy from a retail electric provider of their choice, who bills the delivery charges too.1 In 2025 TNMP's residential delivery revenue averaged 7.09¢ per kWh, about $81.64 a month per home; Texas retail providers' residential customers paid 17.23¢ per kWh on average, delivery included.
EIA-861 2025 final, released October 7, 2026; the next annual release is due in August 2027. Averages are revenue divided by kWh, all charges included: not the rate printed in a tariff.
42 of 254 Texas counties served (EIA-861 2025)
Among the 6 Texas delivery utilities, TNMP had the highest residential delivery average in 2025: 7.09¢ per kWh, or about $81.64 a month per home, before any retail provider adds its energy charge. That average rose +12.0% from 2024, on wires that reach 238,0001 homes in three separate parts of the state.
TNMP's delivery cost per kWh and per month
TNMP (Texas-New Mexico Power Company) is a transmission and distribution utility, or TDU: an investor-owned utility that delivers electricity in the competitive part of Texas but does not sell it. Every home on its wires buys power from a retail electric provider, and the provider passes TNMP's delivery charges through on its bill.
EIA's annual survey of utilities (form EIA-861) reports what each TDU billed for that delivery. In 2025, TNMP's 237,930 residential customers paid an average of 7.09¢ per kWh for delivery: total residential delivery revenue divided by the kWh delivered. With average use of 1,151 kWh a month, that works out to about $81.641 a month per home for delivery alone.
Two cautions apply to these figures. First, the average folds TNMP's fixed monthly customer and metering charges into a per-kWh number, so it is not the per-kWh delivery charge printed in TNMP's tariff; a home using less than average pays more per kWh, one using more pays less. Second, it is only the delivery part of a bill. TNMP has no all-in residential price, because the energy charge comes from whichever retail provider a home picked.

The table sets TNMP against the other delivery utilities in 2025. Its residential average was the highest of the 6, ahead of Lubbock Power & Light at 6.31¢ per kWh and well above Oncor at 5.64¢ per kWh and CenterPoint Energy at 5.41¢ per kWh. Per home the gap is wider still, because TNMP's customers also used slightly more power (1,151 kWh a month, against 1,106 kWh at Oncor and 1,124 kWh at CenterPoint): about $81.64 a month against $62.35 at Oncor and $60.741 at CenterPoint.
How much TNMP delivery rose from 2024 to 2025
TNMP's residential delivery average went from 6.33¢ per kWh4 in 2024 to 7.09¢ per kWh in 2025, a rise of +12.0%1. Average use per home hardly moved between the two years, so the higher average per kWh carried through almost fully to the monthly delivery cost.
Every Texas TDU's average rose over the same two years, by less than TNMP's: +9.7% at CenterPoint, +8.7% at Oncor, +7.7% at AEP Texas North, +4.0% at Lubbock Power & Light and +2.8%1 at AEP Texas Central. These are annual averages for full calendar years; EIA's monthly sample does not include TNMP, so no 2026 figure exists for it yet. The 2025 final data were released on October 7, 2026; the next annual release is due in August 2027.
TDU delivery charges are regulated: the Public Utility Commission of Texas approves them in each utility's rate cases and in the interim adjustments it allows between them. Pending and approved TNMP cases can be searched by utility name on the commission's filing system, where the approved tariff is the source for current charge lines.
Three separate service areas
EIA's service-territory records place TNMP in 423 Texas counties, and they do not form one territory. One group lies on the upper Gulf Coast, in Brazoria, Galveston and Matagorda counties. A second, the largest, spreads across North and Central Texas, from Collin, Dallas and Denton counties out to Archer, Clay and Young in the north and Bosque, Coryell, Hill, McLennan and Robertson to the south, with pockets as far east as Lamar, Red River and Titus. A third sits in far West Texas, in Crockett, Pecos, Reeves, Terrell, Ward and Winkler counties.

In all 423 of these counties at least one other utility also reports customers. Oncor reports customers in most of them; electric cooperatives, city utilities such as Denton's and Garland's, and other delivery utilities such as AEP Texas North and CenterPoint Energy appear in others. The county alone therefore does not show whether a home is on TNMP's wires: the address decides, and plans on Power to Choose are listed by ZIP code and delivery utility. Homes served by a co-op or city utility outside the competitive market cannot choose a retail provider.
Buying electricity in TNMP's area
Because TNMP sells no electricity, what a home pays in total depends on the plan it signs with a retail electric provider. EIA reports what providers collected across all their Texas residential customers, delivery included, but not by TDU area. Across all of them the residential average was 17.23¢ per kWh in 2025; the 38 providers with 10,000 or more residential customers averaged between 8.03¢ per kWh and 20.86¢ per kWh1. Those are past averages across every plan and area each provider served, not offers, and they already include delivery charges such as TNMP's: they are a different measure from the delivery-only average above and cannot be added to it.
Current plans for a TNMP address, each with its Electricity Facts Label showing the price at 500, 1,000 and 2,000 kWh and the TNMP delivery charges it includes, are listed on the Public Utility Commission's Power to Choose site. Our Texas retail choice guide explains how to read a label and compare plans.
Business customers on TNMP's wires
TNMP also delivered to 43,970 commercial and 82 industrial accounts in 2025. Their delivery averages were far below the residential one: 2.18¢ per kWh for commercial and 0.65¢ per kWh for industrial customers. Larger customers use far more kWh per account, often take power at higher voltage, and pay demand charges based on their peak draw, so fixed and network costs are spread over many more kWh. TNMP's commercial delivery average was also lower than Oncor's 3.90¢ per kWh or CenterPoint's 3.84¢ per kWh1, the reverse of the residential order.
Outages and smart meters
TNMP's customers averaged 165 minutes without power in 2025 counting major events (fewer than the Texas average of 225 minutes) and 119 minutes excluding major event days, with 1.502 interruptions per customer. TNMP reports these under another method (not IEEE 1366), so comparisons with other utilities are approximate.

Every residential meter TNMP reported was an advanced meter (100.0%6), read remotely in intervals. Those readings are what allow retail providers in TNMP's area to offer time-of-use and other usage-based plans; the plans themselves, and their hours and prices, come from the providers. The Texas state page places TNMP among all of the state's utilities, including those outside the competitive market.
Questions and answers
What is TNMP's delivery charge per kWh?
EIA's annual census puts TNMP's residential delivery revenue at an average of 7.09¢ per kWh1 in 2025: everything TNMP billed homes for delivery, monthly charges included, divided by the kWh they used. It is an average, not a tariff line. TNMP's approved charges are set by the Public Utility Commission of Texas and appear in every plan's Electricity Facts Label in TNMP's area.
Is TNMP my electricity provider?
No. TNMP owns and runs the poles, wires and meters, but homes on its wires buy electricity from a retail electric provider they choose, and that provider sends the bill with TNMP's delivery charges included.
Who do I call about an outage in a TNMP area?
TNMP, not the retail provider. TNMP restores power, repairs lines and handles meter problems whichever provider a home uses.
Does TNMP serve New Mexico?
Not as a distribution utility. Despite its name, EIA's 2025 records show Texas-New Mexico Power Company delivering to customers in Texas only, inside the ERCOT grid.
