There are several possible reasons your bill may be higher than usual.
1) You used more natural gas this month (your usage will vary by season)
2) Atlanta Gas Light pass-through charges vary by month and tend to be higher in the winter months
3) If you’re on a variable rate, the rate per therm changes monthly and fluctuations in the market could drive your bill up or down
4) If you recently changed from a fixed rate to a variable rate plan, that will affect your bill amount
