See answers to frequently asked questions about billing.
Billed amounts often fluctuate because your utility use differs from month to month. Factors that affect utility use include weather, number of people in the household, new or additional appliances, or vacations.
Your billed amounts can also fluctuate for other reasons, such as gas supply market adjustment costs, changes in distribution service charges and rates, refunds or surcharges, or differences in the number of days in the billing period.
