Does Southern Federal Power Serve My CenterPoint Energy ZIP Code?

Last updated: September 28, 2026

Yes. Southern Federal Power offers residential electricity plans throughout the competitive areas of the CenterPoint Energy service territory. This includes Houston and many surrounding communities across Southeast Texas.

Enter your ZIP code and service address at SouthernFederal.com to see the plans currently available for your home.

A ZIP code is only the starting point. Some ZIP codes cross utility boundaries, so the complete service address determines whether CenterPoint Energy delivers electricity to the property.

What Does CenterPoint Energy Do?

CenterPoint Energy is the Transmission and Distribution Utility, or TDU, for most of Greater Houston.

CenterPoint Energy:

  • Maintains the poles and power lines
  • Reads electric meters
  • Delivers electricity to homes and businesses
  • Responds to power outages
  • Repairs damaged electrical equipment
  • Charges regulated delivery fees

Southern Federal Power is the Retail Electric Provider. Southern Federal offers the electricity plan, sends the bill, accepts payments, and provides customer-account support.

Changing electricity providers does not change the TDU responsible for delivering power to your home.

CenterPoint reports that its Houston electric transmission and distribution system serves more than 2 million customers across a territory of approximately 5,000 square miles. View CenterPoint Energy’s Houston service information.

Why Can One ZIP Code Have More Than One Utility?

ZIP codes were created for mail delivery, not electric utility boundaries.

A single ZIP code can include addresses served by:

  • CenterPoint Energy
  • Texas-New Mexico Power
  • An electric cooperative
  • A city-owned electric utility

Pearland, Alvin, Conroe and several communities near the edge of the Houston area may contain split ZIP codes. Two nearby homes can occasionally have different utilities.

That is why Southern Federal requests both the ZIP code and service address during the shopping and enrollment process.

How Can I Confirm My Delivery Utility?

You can determine the utility for your home in several ways:

  1. Enter your ZIP code and service address at SouthernFederal.com.
  2. Check a previous electricity bill for the TDU or delivery-charge section.
  3. Locate the Electric Service Identifier, commonly called the ESI ID, for the address.
  4. Review the current outage provider associated with the property.
  5. Contact Southern Federal Power customer care for assistance.

The ESI ID is tied to the electric meter and service location. It provides a more reliable identification than a ZIP code alone.

Can I Choose Southern Federal Power if CenterPoint Delivers My Electricity?

Yes. Customers in competitive portions of the CenterPoint Energy territory can choose a Retail Electric Provider such as Southern Federal Power.

CenterPoint will continue to deliver electricity and maintain the local grid. Southern Federal will manage the selected electricity plan, billing, payments and retail account.

There is no need to replace the meter or schedule a technician simply because you change Retail Electric Providers.

  • Power outages
