Decision 86-06-035
D.86-06-035 established procedures for retroactive billing by gas and electric utilities to correct alleged under billings. These rules form the basis for the utilities' tariff rules relating to rendering of bills, meter testing and adjustments for meter and billing error, and adjustment of bills for unauthorized use. Among other things, D.86-06-035 found that "a three month limitation period for backbilling residential customers [for undercharges due to meter error or billing error] is sufficient in view of the utilities' assertion that they have procedures to detect billing and meter errors promptly."11
