FAC charges explained in plain English
FAC is one of the less obvious line items on an electricity bill. It can influence the final amount without changing your actual usage pattern.
What FAC means
Fuel adjustment cost is an additional charge that can vary depending on overall supply conditions and operational factors. It often appears as a separate line item and is worth understanding because it affects the bill total.
Why it matters
Even when consumption remains the same, the FAC portion can shift from month to month. This makes it helpful to review the estimate before paying the final bill.
