How to switch in Texas City

Four simple steps

  • Enter your ZIP — see the Ambit plans available at your address.
  • Compare the real rate — the price at the usage level your home actually runs.
  • Enroll online — pick a plan and sign up in a few minutes, no call required.
  • You are done — Ambit handles the switch with your provider. Your lights never go out, and there is no need to contact TNMP.

Texas-New Mexico Power (TNMP) still owns the poles, wires, and meters and restores outages no matter which plan you pick. Your retail plan only sets your price, term, and billing.

What to compare on every plan

  • Price at 500 / 1,000 / 2,000 kWh — matched to your home size.
  • Minimum-usage fees — charges if you use too little.
  • Bill credits — the usage level where they kick in.
  • Term & early-termination fee — what leaving early costs.
  • Renewable content — the green percentage, if it matters to you.

Pricing varies by ZIP and usage from the Mainland and Bay Street area to Lago Mar and out toward La Marque, so a smart comparison starts with your address, not a single "Texas City average."

Who delivers your power in Texas City

Texas City sits on the Galveston Bay shoreline, where Texas-New Mexico Power (TNMP) is the regulated Transmission and Distribution Utility (TDU). They own the poles, wires, and meters, restore outages, and set the delivery charges that are the same for every retail provider.

  • Report an outage: TNMP at (888) 866-7456 — not your retail provider.
  • Your Ambit plan only sets your price, term, and rewards.
  • Switching never interrupts your power or changes who fixes outages.

What this means for Texas City homes

From the refinery district and the Mainland to the master-planned neighborhoods near Lago Mar, Texas City runs on the TNMP grid. Whichever retail plan you choose, TNMP still delivers the power and restores outages, so you are free to pick Ambit purely on price and rewards.

Serving the Mainland, Lago Mar, the Bay Street and 6th Street corridor, and nearby La Marque. Enter your ZIP to see the exact plans at your address.

About Texas City

Texas City is a deepwater port and petrochemical hub on the southwest shoreline of Galveston Bay, in Galveston County along the Gulf Coast. It is one of the larger cities in the county and grew up around the refineries and chemical plants that line its waterfront, including the Galveston Bay Refinery operated by Marathon Petroleum and the Valero Texas City refinery. Today the city blends that heavy-industry base with newer residential growth, from established Mainland neighborhoods to master-planned communities like Lago Mar near the Gulf Freeway, with neighboring La Marque just to the north. In a city built on energy, retail electric choice lets Texas City homeowners shop the open market for their own plan instead of taking whatever a single utility offers.
