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.

The Contribution Tax Adder is a fee, required by law, to be paid to utilities by customers, developers and builders. This charge offsets the taxes utilities pay for including contributions-in-aid of construction payments as our taxable income.
In addition, utilities must include in their taxable income and pay taxes on, any utility improvements installed by developers and builders, which are then given to the utility as a contribution to gross income. As a result, the Contribution Tax Adder is a fee, and therefore, is not exempt from taxes.
