Adjustment of Bills.
(A) Adjustments Due to Meter Errors. If any service meter, after being tested, as provided for in these rules, is found to have a percentage of error greater than three percent (3%) for watthour meters and four percent (4%) for demand meters, the bills for service shall be adjusted as follows:(1) Fast Meters-When a meter is found to have a positive average error, the public utility shall refund, or credit the customer's account with the amount of any charges in excess of either (i) an average bill for the kilowatthours and/or demand units incorrectly metered or (ii) separate bills individually adjusted for the percent of error for the period the meter was fast, if such period can be determined, or one year, whichever period is shorter. An average bill shall be calculated on the basis of kilowatthours and/or demand units registered on the meter over corresponding periods either prior or subsequent to the period for which the meter is determined to be fast. No part of a minimum service charge shall be refunded.(2) Stopped or Slow Meters-When a meter is stopped or has a negative average error, the public utility may charge the customer for the kilowatthours and/or demand units incorrectly registered for one-half of the period since the last previous test or one year, whichever is shorter. The amount of the charge to the customer shall be estimated on the basis of either (i) an average bill as herein below described or (ii) separate bills individually adjusted for the percent of error. An average bill shall be calculated on the basis of kilowatthours and/or demand units registered on the meter over corresponding periods either prior or subsequent to the period for which the meter is determined to be slow or stopped. The utility may charge the customer for such amounts except where the utility negligently allows the stopped or slow meter to remain in service. (B) Other Billing Adjustments. All other billing errors, including incorrect tariff applications, may be adjusted to the known date of error or for a period of one year, whichever period is shorter.Indiana Utility Regulatory Commission; No. 33629: Standards of Service For Electrical Utilities Rule 14; filed Mar 10, 1976, 9:10 am: Rules and Regs. 1977, p. 346; readopted filed Jul 11, 2001, 4:30 p.m.: 24 IR 4233; readopted filed Apr 24, 2007, 8:21 a.m.: 20070509-IR-170070147RFA; errata filed Jul 21, 2009, 1:33 p.m.: 20090819-IR-170090571ACA; readopted filed Aug 2, 2013, 2:16 p.m.: 20130828-IR-170130227RFAReadopted filed 4/11/2019, 9:04 a.m.: 20190508-IR-170190136RFA
