    About the Texas Deregulated Market

    How long does it take to switch providers?+
    1 to 7 days, completed by your next meter read. No service interruption. New-address connections can usually happen same-day or next-day.
    What's the difference between CenterPoint and Ambit?+
    CenterPoint Energy owns the poles, wires, and meters (the Transmission & Distribution utility). Ambit is the retailer that sells your plan and sends your bill. You choose the retailer; the TDU is fixed by geography.
    Fixed vs variable rates — which should I pick?+
    Fixed locks your ¢/kWh for 12, 24, or 36 months. Variable can change monthly with wholesale prices. Most Texas households pick fixed for budget predictability, especially during summer peak months.
    What is the E-Plan discount?+
    Ambit's paperless billing discount — enroll in email-only billing and your rate drops by 0.2¢/kWh. Rates on this page assume E-Plan is enabled; add 0.2¢/kWh for paper billing.
    Do you have Spanish-language support?+
    Yes — our site is fully bilingual and phone support is available in Spanish. Ver esta página en español →
