Same-Day Electricity in Texas: AMS Smart-Meter Cutoff Times by Utility
Because more than 99% of homes and apartments in competitive ERCOT territories have Advanced Metering System (AMS) smart meters, Texas retail electric providers can energize your meter remotely the same day you enroll—provided your order passes credit/ID verification before the daily TDU priority cutoff (typically 2:00 PM to 5:00 PM Central Time, Monday through Saturday).

1. Same-Day Move-In Cutoff Windows Across Texas TDUs
While the Retail Electric Provider (REP) processes your enrollment, the physical remote connect command is executed by your local Transmission and Distribution Utility (TDU). Here are the standard priority same-day move-in windows across ERCOT:
| TDU Utility Territory | Typical REP Enrollment Cutoff (CT) | Saturday Remote Connect? | AMS Standard Move-In Fee |
|---|---|---|---|
| Oncor Electric Delivery (DFW, Waco, Midland, Odessa) | 3:00 PM – 5:00 PM CT (Mon–Sat) | Yes (AMS meters) | $0 – $2.35 standard |
| CenterPoint Energy (Greater Houston Metro) | 2:00 PM – 5:00 PM CT (Mon–Sat) | Yes (AMS meters) | $0 – $5.00 standard |
| AEP Texas Central & North (Corpus Christi, RGV, Abilene) | 2:00 PM – 4:00 PM CT (Mon–Sat) | Yes (AMS meters) | $0 standard |
| TNMP (League City, Lewisville, Pecos) | 2:00 PM – 4:00 PM CT (Mon–Fri) | Limited / REP-specific | $0 – $6.00 standard |
2. Why Same-Day Move-In Orders Get Delayed (and How to Prevent It)
Even if you submit your order before 2:00 PM CT, three issues can stall remote meter activation until the next business day:
- Apartment Unit / ESI ID Mismatch: In large apartment complexes, unit numbering in postal addresses (e.g., “Apt 204” vs “Bldg 2 #204”) may not match the ERCOT master meter registry. Verify your exact 17- or 22-digit ESI ID using our Texas ESI ID Lookup Tool before checkout.
- Unpaid Deposit Hold: If a provider requires a security deposit or identity verification document, the ERCOT 814_16 Move-In transaction is not transmitted to the TDU until the deposit payment clears.
- Municipal Permit / City Inspection Hold: If a meter has been de-energized for more than 6 to 12 months, or after electrical panel work, the city code office may place a permit hold requiring a physical inspection before the TDU can energize the meter.
Frequently Asked Questions
How long does it take for the power to turn on after my same-day order is approved?
Once your retail provider transmits the priority move-in transaction to Oncor, CenterPoint, AEP, or TNMP, an AMS smart meter typically energizes within 1 to 4 hours, and no later than 8:00 PM CT that evening.
Do I need to be home when the smart meter is turned on?
No. Remote AMS smart-meter activation does not require a technician visit. However, you should ensure your main breaker inside the home is switched on and that stoves or space heaters are turned off before power is restored.
