Texas New-Mexico Power, commonly referred to as TNMP, is a subsidiary of PNM Resources (NYSE: PNM) and an electricity transmission and distribution utility company serving more than 260,000 homes and businesses throughout the state of Texas. With its headquarters in Lewisville TX, TNMP has a workforce of roughly 400 employees operating in more than 20 communities throughout the state. Despite its name, TNMP currently only serves customers in Texas. 

What does TNMP do?

TNMP owns, manages, and operates the poles, wires and all of the required infrastructure to get electricity from the power plants delivered to your home or business. They also read your electric meter each month and report that data back to your provider for billing purposes. 

Additionally, TNMP will be the first to respond in the event of a power outage or emergency. They are charged with restoring power to the grid. In the event there are trees close to power lines, within 10ft, then they also provide tree trimming services as well.

You will never receive a bill directly from TNMP for your monthly electricity usage. That is done by and through your retail electricity provider, who will compile all of your charges into one bill.

History of TNMP

TNMP’s roots begin in December 1934 with its original name, Community Public Service Co. It took ownership of all properties and assets of Texas-Louisiana Power Co. and began operations on January 1, 1935.

Community Public Service serviced most of the communities now served by TNMP, plus some additional communities in Texas and communities in New Mexico. It operated as power producer, distribution company and provider of customer service and billing.

It also briefly operated businesses in natural gas, ice, telephone, sewer, creameries and bottling, among others.

Other key dates in TNMP company history

  • 1951: The company exits the ice business.
  • 1962: R.L. Bowen, the company president since 1935, retired and became chairman of the board, a role he held until the 1970s.
  • Early 1970s: Community Public Service completed its exit from all remaining non-electricity businesses.
  • 1981: Community Public Service changed its name to Texas-New Mexico Power.
  • 1984: TNP Enterprises was formed as a holding company for TNMP to allow diversification of business endeavors while keeping the utility operation independent.
  • 2002: The Texas deregulated market began. TNMP in Texas remained a fully regulated transmission and distribution service provider in its established service area, constructing and maintaining lines and substations, coordinating new service and meter services and responding to outages. TNMP in New Mexico continued to operate as a traditional utility.
  • 2005: TNP Enterprises, including TNMP, was acquired by PNM Resources.
  • 2006: TNMP’s New Mexico business, including the electric system, workforce and customer pricing and billing responsibilities, was moved into its sister company in New Mexico, making TNMP a Texas-only business.
  • 2008: TNMP moved its headquarters from Fort Worth, TX to Lewisville, TX.

Cartoon of 3 diverse people seeking answers to frequently asked questions

Will TNMP send someone to read my meter?

Now that advanced smart meter technology has been installed at every home and business, people are no longer deployed to physically come out and actually read your meter. Your meter information is electronically transmitted each and every month to TNMP which then gets passed on to your retail electric provider for billing purposes.

How can I find out how much electricity I am using?

You can view your electricity usage at the Smart Meter Texas website. The website stores daily, monthly and 15-minute interval electric usage data recorded by your smart meter. Alternatively, you can use TNMP’s proprietary Data Viewer as well. 

Is there a way that I can read my own smart meter?

Since everything is digitized, the best and safest way to read your meter and review advanced graphs and charts about your energy consumption is to visit the Smart Meter Texas website or TNMP’s Data Viewer.

How can I find out my meter reading cycle?

You can find out your meter reading (or billing) cycle on your monthly electric bill. It is typically a single or double digit number. To then find out what day of the week it falls on, or other interesting details, TNMP publishes its meter reading cycle for every year. It details the days in which it is read as well the number of days in each billing cycle. Click here to view the most current billing cycles.

Does TNMP know when the power goes out?

Generally, yes. But that’s if their systems detect a power outage. A good way to ensure that your outage is reported and to stay informed is to report that you’re without power by dialing 888-866-7456 (select option 1).

Why is my power off, but my neighbors across the street still have their lights on?

In many instances, your neighbors may have their power on when you don’t because their home is on a different set of power lines or circuit. You can report a power outage or check the status of a previously reported power outage by calling 888-866-7456 (select option 1).

Why is my electric bill so high?

The most common cause of a high electric bill is the weather. As the temperature outside becomes more extreme, so can electric bills. Your electric bill is based on the amount of electricity you use and the rate charged by your Retail Electric Provider (REP) which includes TNMP’s cost to deliver the electricity to your home or business. For more information, contact your REP at the number listed on your bill. Click here to learn
