The first lets you know if your electric service is on. Generally, the display will read “CLS” when the power is on and “OPN” if your electricity is off.
The second shows you how much electricity in kilowatt-hours (kWh) you have used for the current billing term. That’s also called your cumulative usage.
The third number shows your electricity demand reading. Your TDU uses this number to calculate the amount of electricity being used by people in your service area at various times.
