TNMP Business Electricity Rates: Compare Commercial Plans in the Texas-New Mexico Power Territory
Businesses in the Texas-New Mexico Power service territory can shop for their retail electric provider, but TNMP still handles the local delivery system. That means your business can compare commercial electricity plans while TNMP remains responsible for poles, wires, meters, delivery service, and outage response.

Use the live commercial-rate section below to compare current TNMP business electricity plans. The default ZIP code is set for Texas City, but your exact service address, usage, demand, and business profile can affect available offers.

How TNMP fits into your business electric bill
In Texas electric choice areas, the retail electric provider sells the electricity plan to your business. TNMP is the delivery utility when the meter is in its service territory, so it handles delivery infrastructure, metering, and many outage-related functions.
TNMP publishes its Retail Delivery Service Tariff, which contains delivery charges and service rules for its certified service area. Switching REPs can change the energy supply price and contract terms, but it does not change which utility delivers power to the meter.
Your REP controls
- Energy price and contract term
- Fixed, indexed, variable, or custom business offer
- Billing format, renewal terms, and customer service
TNMP controls
- Delivery infrastructure in the TNMP service territory
- Metering and local delivery service
- Outage response, hazard reports, and restoration work
TNMP commercial delivery charges to know
Commercial delivery charges depend on the rate class assigned to the meter. TNMP’s non-residential tariff commonly separates smaller secondary service accounts from larger secondary, primary, and transmission service accounts.
The table below summarizes selected TNMP delivery charge components from the current retail tariff. Actual bills may also include riders and other pass-through items, so use this as a plain-English shopping guide rather than a complete bill calculator.
| TNMP commercial rate category | Base fixed charges | Base delivery component | Business meaning |
|---|---|---|---|
| Secondary Service ≤ 5 kW | $0.74 customer charge + $7.62 metering charge | $0.042580 per kWh distribution system charge | Often relevant for very small commercial accounts with low demand. |
| Secondary Service > 5 kW | $3.60 customer charge + $20.96 metering charge | $7.0585 per NCP kW at load factor ≤25%; $5.7256 per NCP billing kW at load factor >25% | Demand and load factor matter. A low energy rate may not mean the lowest total bill. |
| Primary Service | Fixed charges and metering charges follow the tariff schedule | $4.534 per NCP billing kW distribution system charge | Relevant for larger or more complex business service situations. |
Business tip: compare the all-in price, not just the advertised cents-per-kWh rate. For commercial accounts, your demand pattern, load factor, and rate class can matter as much as your total kWh usage.
Why the cheapest posted business rate may not be the best deal
A low advertised rate can be helpful, but commercial electricity shopping should consider how the plan behaves under your actual usage profile. A small shop, warehouse, restaurant, church, school, medical office, or industrial account can have very different demand patterns.
- Check whether the price is fixed for the full term or can change.
- Compare contract length, renewal language, and early termination terms.
- Review whether pass-through charges are billed separately or bundled.
- Know whether demand, load factor, usage swings, or seasonal peaks affect your account.
Where the TNMP service territory matters for shopping
TNMP’s service area is not one single city block; it includes areas in North-Central Texas, the Gulf Coast, and West Texas. The right way to shop is by service address or ZIP code because electric offers are tied to the delivery utility and meter location.
For business owners searching phrases like “cheap business electricity TNMP,” “TNMP commercial electricity rates,” “business electric plans near me,” or “lowest commercial electricity rates in Texas City,” the important first step is confirming that the meter is actually in TNMP territory.
A simple checklist before you choose a TNMP business plan
- Find a recent bill and confirm your ESI ID, ZIP code, and delivery utility.
- Review 12 months of kWh usage if available.
- For larger accounts, review monthly peak demand or request interval usage.
- Compare multiple terms, not just one 12-month plan.
- Ask whether the quoted rate includes or excludes delivery pass-through charges.
- Confirm renewal and termination language before signing.
Outages, hazards, and who to contact
If the issue is a power outage, downed line, or delivery equipment problem, contact TNMP through the outage resources. TNMP recommends reporting outages through the outage map first, and its outage page lists 888-866-7456 for outage reports and hazard reporting.
If the issue is your plan price, renewal, contract, billing format, or supplier terms, that is usually a retail electric provider question. Your business may still be able to shop for a better commercial electricity plan before renewal.
FAQ: TNMP business electricity rates
Can my business switch away from TNMP?
No. Your business can shop for the retail electric provider, but TNMP remains the delivery utility when your meter is in TNMP’s service territory.
Why do delivery charges still appear after switching providers?
Delivery charges are utility pass-through charges for the local delivery system. They can appear on the bill regardless of which REP your business chooses.
What makes TNMP business electricity different from residential electricity?
Business accounts may be affected by demand, load factor, contract volume, usage shape, and delivery rate class, not only total kWh.
