Sometimes Atlanta Gas Light estimates your meter reading instead of taking an actual reading. When this happens, your bill is based on projected usage rather than measured consumption. Understanding how estimates work helps you manage your bills and catch potential issues.
Estimated readings are indicated on your bill with an "E" or "EST" notation. While estimates are designed to be accurate based on your usage history, they can sometimes differ significantly from actual usage.
Why Meters Get Estimated
AGL may estimate your meter reading for several reasons:
- Access issues: Locked gates, aggressive pets, or obstructed meters
- Weather conditions: Severe weather preventing safe meter reading
- Meter problems: Damaged or malfunctioning meter displays
- Staffing constraints: Temporary scheduling issues
Most meters are read monthly, but occasional estimates are normal. Consecutive estimated readings may indicate an access problem that needs to be resolved.
How Estimates Are Calculated
AGL calculates estimated readings based on your historical usage patterns, adjusted for weather conditions. The algorithm considers:
- Your usage during the same month in previous years
- Recent actual readings to establish current patterns
- Heating degree days (weather-based adjustment)
While estimates are generally accurate, they may not account for changes in your household—new appliances, different occupancy, or changes in heating habits.
Correcting Estimated Bills
When an actual reading is taken after an estimate, your bill is automatically adjusted. If the estimate was too high, you'll receive a credit; if too low, you'll owe the difference.
If you believe an estimate is significantly wrong, you can request a re-read or submit your own meter reading. AGL's website and app allow customers to submit readings, which can prevent large catch-up bills.
Preventing Estimated Readings
To ensure accurate readings, keep your meter accessible: trim vegetation, secure pets during reading days, and ensure gates can be opened. If your meter is inside, consider requesting an outside meter relocation.
You can also submit your own reading through AGL's website if you notice your bill is estimated. This helps ensure accuracy and prevents surprise adjustments later.
