Reporting an outage? Call the TDU

When a power outage occurs, you’ll receive faster, more accelerated service by contacting the TDU (such as TNMP) rather than the electric provider who supplies your electricity in Texas.

It’s helpful to grasp the difference between the TDU (also called TDSP) and electricity company, and to have a list of Texas TDU phone numbers you can contact when an electrical outage occurs in your area.

Use Smart Meter Texas to see how outages affects usage

If a Texas-New Mexico power outage occurs in your region, you can evaluate the effects of the outage on your energy consumption for a given month by looking at your Smart Meter Texas meter usage data.

To review your meter history obtained by TNMP, you can start a free account with Smart Meter Texas. You can also browse through our guide on Smart Meters.

Avoid energy rate spikes from demand surges caused by outages

Electric outages caused by escalating electricity demand can cause considerable rate spikes, resulting in rises in your energy bills if you’re not enrolled in a fixed-rate plan that locks in your price.

Increases in demand are more likely to happen during extremely hot Texas summer months when energy demand is at its peak.

Electricity Rates: If you’re on a variable energy rate plan such as a month-to-month plan, a wholesale rate or an index rate plan that floats with the market, you can cut bill surprises by signing up for a fixed-rate plan from the best light companies operating in the Texas-New Mexico Power zone on our home page.

Be sure to evaluate a plan’s EFL to determine if an energy plan is a good match for your home’s energy usage.

Texas Energy Promo Code Deals: Due to our strong bargaining power with energy providers, we’re able to offer exclusive energy discount codes that give you access to discounted energy rates from the best providers in Texas.

What to do in during a power outage?

  • Check with your neighbors to see if the TNMP power outage is not just your home.
  • Electrical surges that occur after outages can destroy electronic devices, so unplug devices after an outage.
  • Find another place to stay in case of a dire need for heating or cooling.
  • Keep your refrigerator and freezer closed at all times.

After unplugging your devices, consider calling your TDU to determine the status of the outage. For real time updates, check the TNMP Outage Map. After completing the steps above, you should move to a different place if you’re in need of cooling or heating.

If it’s cold and you don’t have anywhere else to go, don’t use a gas stove for heating due to safety risks.

You can prepare for outages by having backup batteries and other sources of additional power. Having a landline phone is a good backup because they don’t require electricity to make calls. Extra power sources are important for medical devices that need electricity.

If you own a generator, move it away from your home and keep it a good distance from doors and windows. If you live in a rural area and depend on your generator for energy, have an extra supply of fuel that you can use for emergencies.

Save the Texas-New Mexico power outage number for your location on your phone.  You could also write it out and keep it in a safe location that you will remember.
