Does Southern Federal Power Serve My TNMP ZIP Code?
Southern Federal Power offers residential electricity plans in many Texas ZIP codes served by Texas-New Mexico Power, commonly called TNMP.
To check your location, visit SouthernFederal.com, enter the ZIP code for your service address and review the plans currently available.
A matching ZIP code does not always guarantee that TNMP serves the address. Utility boundaries do not follow ZIP-code or city boundaries, and some ZIP codes include more than one electric delivery company. Your complete service address provides the final confirmation.
What Is the TNMP Service Area?
Texas-New Mexico Power is a Transmission and Distribution Utility, also called a TDU or TDSP. TNMP maintains the poles, power lines, meters and other equipment used to deliver electricity within its service territory.
Unlike utilities with one mostly connected territory, TNMP serves separate areas across Texas. Its service areas include portions of:
- North-Central Texas
- Central Texas
- The Texas Gulf Coast
- West Texas
TNMP’s official territory information includes communities such as Lewisville, Pilot Point, Princeton, Farmersville, Clifton, Gatesville, Glen Rose, Alvin, Angleton, Friendswood, League City, Texas City, Pecos, Kermit and Fort Stockton.
Southern Federal Power and TNMP have different responsibilities:
- Southern Federal Power offers electricity plans, sends bills and provides retail account support.
- TNMP delivers electricity, reads meters, maintains the local distribution system and responds to outages.
Selecting Southern Federal Power does not change the utility responsible for the poles and wires serving your address.

TNMP ZIP codes appear in separate parts of Texas rather than one continuous geographic area.

These are examples, not a guarantee of service. Some ZIP codes cross utility boundaries or contain addresses served by a municipal utility or electric cooperative.
Always confirm the complete service address before selecting an electricity plan.
How Do I Check My TNMP Address?
Follow these three steps:
- Visit SouthernFederal.com.
- Enter the ZIP code for your service address.
- Confirm that TNMP is the delivery utility and review the available Southern Federal Power plans.
Plan availability, prices and contract options can change. The plans displayed for the service location provide more useful information than a general ZIP-code list.
Customers can also enter their ZIP code at PowerToChoose.org, the official electricity-shopping website operated by the Public Utility Commission of Texas.
Can Two Addresses in the Same ZIP Code Have Different Utilities?
Yes. ZIP codes are created for mail delivery and do not necessarily match electric utility boundaries.
This is especially important in areas around Houston, Dallas-Fort Worth and smaller Texas communities where multiple utilities may operate near one another. Two homes in the same city or ZIP code may be connected to different delivery systems.
The complete service address and its Electricity Service Identifier, commonly called an ESI ID, are more reliable than the ZIP code alone.
Is TNMP My Electricity Provider?
TNMP delivers electricity, but it is not the Retail Electric Provider that offers your plan and sends your electricity bill.
TNMP explains that customers in Texas’s competitive market interact with two companies:
- The Retail Electric Provider handles billing and most customer service.
- The poles-and-wires company delivers electricity and reads the meter.
For Southern Federal Power customers in TNMP territory, Southern Federal manages the retail account while TNMP maintains the local delivery system.
Who Handles a TNMP Power Outage?
If your address is served by TNMP, report power outages, damaged lines and electrical hazards directly to TNMP.
TNMP outage number: 1-888-866-7456
Outage map: outagemap.tnmp.com
TNMP recommends using the report-outage option on its outage map or calling the outage number and selecting option 1.
For questions about your Southern Federal Power plan, bill or retail account, call Southern Federal Customer Care at 1-844-644-0474.
