(10) To the extent that a utility uses the concepts identified in this paragraph in a customer's bill, it shall use the term set out in this paragraph, and the definitions in this paragraph shall be easily located on the utility's website. A utility may not use a different term for a charge that is defined in this paragraph. (A) Current Meter Read--The meter reading at the end of the period for which the customer is being billed; (B) kW--Kilowatt, the standard unit for measuring electricity demand, equal to 1,000 watts; (C) kWh--Kilowatt-hour, the standard unit for measuring electricity energy consumption, equal to 1,000 watt-hours; and (D) Previous Meter Read--The reading on the beginning the period for which the customer is being billed. (d) Estimated bills. (1) An electric utility may submit estimated bills for good cause provided that an actual meter reading is taken no less than every third month. In months where the meter reader is unable to gain access to the premises to read the meter on regular meter reading trips, or in months when meters are not read, the electric utility must provide the customer with a postcard and request the customer to read the meter and return the card to the electric utility. If the postcard is not received by the electric utility in time for billing, the electric utility may estimate the meter reading and issue a bill. (2) If an electric utility has a program in which customers read their own meters and report their usage monthly and no meter reading is submitted by a customer the electric utility may estimate the customer's usage and issue a bill. However, the electric utility must read the meter if the customer does not submit readings for three consecutive months so that a corrected bill may be issued. (e) Record retention. Each electric utility shall maintain monthly billing records for each account for at least two years after the date the bill is mailed. The billing records shall contain sufficient data to reconstruct a customer's billing for a given month. Copies of a customer's billing records may be obtained by that customer on request. (f) Transfer of delinquent balances. If the customer has an outstanding balance due from another account in the same customer class, then the utility may transfer that balance to the customer's current account. The delinquent balance and specific account shall be identified as such on the bill.
