Utility vs. provider

What TNMP Does

Texas splits electricity service between two companies. TNMP is the transmission and distribution utility (TDU) for its service areas, which means it manages the poles and wires that deliver electricity to your home. Despite its name, TNMP only delivers electricity in Texas. You can't choose your TDU, but you can choose the electricity provider that supplies your energy.

TNMP

  • Owns and maintains the poles, wires and substations
  • Restores power after outages and storms
  • Installs and reads your smart meter
  • Connects and disconnects service when you move
  • Sets regulated delivery charges, approved by the PUCT

Your electricity provider

  • Sells you the electricity plan and sets its energy rate
  • Sends your monthly bill, including TNMP's charges
  • Handles enrollment, payments and customer service
  • Sets contract length, fees and renewal terms

On your bill

TNMP Delivery Charges

Every home in the TNMP area pays the same regulated delivery charges, no matter which provider it uses. TNMP doesn't bill you directly. The charges appear on your electricity provider's monthly bill, and they change several times a year as the PUCT approves updates.

Example: A 1,000 kWh Month

Here is how TNMP's charges add up on the bill for a home that uses 1,000 kWh in a month.

Monthly charge$7.56
Delivery charge1,000 kWh × 7.7710¢$77.71
TNMP charges on your bill$85.27

Your provider's own energy charge is added on top. At 500 kWh, TNMP's charges come to about $46.41; at 2,000 kWh, about $162.98.

What Makes Up the Charge

  • Customer and metering charges

    The monthly charge is two fixed charges you pay regardless of usage: a customer charge for the cost of serving your account, and a metering charge for installing, reading and maintaining your meter.

  • Distribution charge and riders

    The per-kWh charge combines TNMP's base distribution rate with riders that recover specific costs, including transmission and the cost of repairing the grid after hurricanes.

Why it matters

When TNMP's delivery charges change, many plans pass the change straight through to your bill, including some fixed-rate plans. Your plan's EFL says whether yours does.

Where it serves

Some cities, such as League City, Friendswood and Lewisville, are split between TNMP and a neighboring utility, so confirm your address when you shop: plans offered at your address will list TNMP as the utility.

  • La Marque
  • Dickinson
  • Friendswood
  • League City
  • Lewisville
  • Glen Rose
  • Gatesville
  • Pecos
  • Fort Stockton

When the power goes out

Reporting a TNMP Outage

Outages are TNMP's responsibility, not your provider's. Your provider can't dispatch a crew or speed up a restoration, so report the outage to TNMP directly.

  • Call TNMP at 888-866-7456 to report the outage, any time of day
  • Check TNMP's outage map for the estimated restoration time in your area
  • Stay away from downed lines and call 911 if you see one

Switching Providers and Moving

Switching providers doesn't change your utility. TNMP keeps delivering your electricity, reading your meter and handling outages. Your new provider submits the switch, so there is typically no interruption in service and no technician visit.

When you move to a new home in the TNMP area, you sign up with a provider for the new address and the provider asks TNMP to start service. Because TNMP reads your smart meter remotely, your usage history is also available through Smart Meter Texas, which is the most accurate way to compare plans at your real usage.
