"Delinquent amount" means the portion of a customer's account representing charges for utility service or services past due. In the case of a residential customer on either a budget billing plan or a payment schedule, "delinquent amount" means the lesser of the outstanding account balance or the outstanding scheduled payments.
"Late payment charge" means the allowable charge a utility may impose upon a delinquent amount.
"Residential customer" means a customer of a utility whose principal use of gas or electricity is for household purposes such as lighting, cooking, water heating, and space heating in space occupied as living quarters. Utility service is normally supplied through a single meter to a single family dwelling unit, but apartments or other subdivided dwelling units may be classified as residential even though several individual units take service through the same meter.
