Reading Your Meter
The meter face on your Smart Meter shows three separate rotating displays. Each display flashes for five seconds. The displays include:
- Status of your electricity service — Is the power on or off? What does OPN and CLS means?
- Cumulative electric usage — used by your Retail Electric Provider in bill calculation
- Electric demand reading — a view for AEP Texas operational use only
New Digital Smart Meters
The Power Status Display tells you whether your electric service is on. You will see either:
- OPN -- This means your power is off.
- CLS -- This means your power is on.

Cumulative Electric Usage Display
The Cumulative Electric Usage Display shows your cumulative usage in kilowatt-hour (kWh) up to your current billing period. Your Retail Electric Provider uses this number to calculate your bill. You may also wish to refer to this number if you are keeping track of your kWh usage.
A kilowatt-hour is a unit of electrical consumption equal to the amount of electricity needed to burn ten, 100-watt light bulbs for one hour.
The Reference Number 1 is unique to the Cumulative Electric Usage Display. The meter number is a unique identifier for your meter.

Electric Demand Reading Display (For AEP Texas operational use only)
The Electric Demand Reading Display is a kilowatt (kW) reading used by AEP Texas. (It is not used in billing calculations.)
A kilowatt is a unit of electrical consumption equal to 1,000 watts.
The Reference Number 21 is unique to the Electric Demand Reading Display. The meter number is a unique identifier for your meter.
