If you live in Texas City, League City, or parts of North and West Texas, your electricity is delivered by Texas-New Mexico Power (TNMP). While you choose your Retail Electric Provider (REP) to buy electricity, TNMP is the Transmission and Distribution Utility (TDU) responsible for maintaining the physical grid. When you open your monthly electric bill, you might notice recurring line items that impact your overall energy costs. Understanding how tnmp delivery charges work is key to managing your household budget and finding the most cost-effective energy plan.

What Are TNMP Delivery Charges?

TNMP delivery charges—sometimes referred to as TDSP or TDU charges—are the fees approved by the Public Utility Commission of Texas (PUCT) to cover the cost of transporting electricity from power plants to your home. These charges are passed through from the utility to your REP, who then includes them on your monthly bill. Because these rates are regulated, they remain the same regardless of which retail provider you choose.

The Components of Your Utility Delivery Fees

These fees are divided into two main categories: a fixed monthly customer charge and a variable assessment based on your usage. The fixed fee is a flat charge applied each billing cycle to maintain your connection to the grid. The variable assessment is calculated per kilowatt-hour (kWh) of electricity you consume, covering the upkeep of local power lines, poles, and meters.

Why Do These Charges Exist in the TNMP Service Area?

Unlike some utility companies that serve one massive, contiguous territory, TNMP operates a unique, scattered grid. Serving approximately 270,000 customers in non-contiguous communities across Texas, TNMP must maintain infrastructure spanning from the Gulf Coast to the suburbs of Dallas-Fort Worth and far West Texas. This geographic reality means maintaining the grid requires significant coordination and resources, which are funded through these regulated delivery charges.

Understanding Your Bill Helps in Emergencies

Recognizing the difference between your retail provider and TNMP does more than just clarify your monthly bill—it also keeps you safe. While your REP handles billing and customer service for your plan, TNMP owns and maintains the physical infrastructure. In the event of a power outage, downed power line, or meter emergency, you must contact TNMP directly to report the issue, as your retail provider cannot dispatch crews to restore power.

Frequently Asked Questions

Can I avoid paying TNMP delivery charges?

No, these charges are mandatory and regulated by the PUCT. Every customer living within the TNMP service territory must pay these fees to support grid maintenance, regardless of which Retail Electric Provider they choose.

Do TNMP delivery charges change throughout the year?

Yes, the Public Utility Commission of Texas typically adjusts these delivery rates twice a year (usually in the spring and fall) to reflect the utility’s operational costs.

Who should I call if my power goes out in a TNMP area?

You should contact TNMP directly to report outages or electrical emergencies. Your Retail Electric Provider only manages your billing and electricity contract, not the physical power lines.
