PSC 134.14(1)(1) Whenever a meter is found to have a weighted average error of more than 2% fast as tested in the manner specified in s. PSC 134.28, a recalculation of bills for service shall be made for the period of inaccuracy assuming an inaccuracy equal to the weighted average error. Weighted average error refers to 80% of the open rate plus 20% of the check rate. The recalculation shall be made on the basis that the service meter should be 100% accurate.

PSC 134.14(2)(2) If the period of inaccuracy cannot be determined, it shall be assumed that the full amount of inaccuracy existed during the last half of the period since the previous test was made on the meter; however, the period of accuracy shall not exceed one-half the required test period.

PSC 134.14 NoteNote: If the meter test period is 15 years and the meter had been in service for 16 years, the period of accuracy shall be 7½ years, and the period of inaccuracy shall be 8½ years.

PSC 134.14(4)(4) If the recalculated bills indicate that more than $1 is due an existing customer or $2 is due a person no longer a customer of the utility, the full amount of the calculated difference between the amount paid and the recalculated amount shall be refunded to the customer. The refund to an existing customer shall be a credit to the customer’s current bill. If the amount of the credit is greater than the current bill, the amount in excess of the current bill shall, at the discretion of the customer, be made in cash or as credit on future bills. If a refund is due a person no longer a customer of the utility, a notice shall be mailed to the last known address, and the utility shall upon request made within 3 months thereafter refund the amount due.
