27. Metering and Meter Testing and Billing Errors
27.1 The PUD will install and maintain all meters and other equipment necessary for measuring the Energy used by the Customer. The PUD will maintain accurate records of all meter readings for billing purposes. The Energy delivered as evidenced by such record shall, in the absence of proven error, be prima-facie evidence of the use of such Electric Service by the Customer, and shall be the basis for computing all bills.
27.2 The PUD will make necessary periodic tests and inspections on its meters to ensure a high standard of accuracy. Additional meter accuracy tests may be requested by the Customer. If the meter registers are found to deviate by plus or minus two (2) percent, the PUD will pay for the testing and will adjust the Customer’s billing for the known or assumed period of error in accordance with Section 15. Adjustment of Utility Bills. If the meter is operating within plus or minus two (2) percent accuracy, the Customer may be billed for the testing expense according to Rate Schedule 90 – Miscellaneous Charges and Fees.
27.3 Should any meter malfunction and incorrectly register the amount of Energy usage, the Customer shall be notified as soon as possible after the metering malfunction is discovered. The Customer may receive a refund or be surcharged for up to two (2) years of service based on Customer’s estimated Energy usage or Demand. The energy usage or demand shall be determined based on prior or current usage and demand patterns, excluding the period in which the malfunction occurred. This section does not apply to meters that have been intentionally altered, moved, modified or otherwise tampered with.
27.4 In the event a billing error is discovered by the PUD, the PUD shall notify the Customer and the Customer may receive a refund or be surcharged to correct any overcharge or undercharge on a Customer’s bill. In the event a billing error is discovered by the Customer, the Customer shall immediately notify the PUD in writing, and explain in detail the disputed charges. If the PUD determines that a billing error has occurred, the Customer may receive a refund or be surcharged to correct any overcharge or undercharge on a Customer’s bill. The period for which any refund or surcharge will apply shall not exceed two (2) years of billings, and any refunds or surcharges shall be made in the PUD’s sole discretion.
27.5 The PUD does not share meter information, meter readings, or any other Customer Data with third parties unless required by law or as needed for PUD operations. The information generated by the PUD electric meters is used by the PUD internally in matters involving kWh usage for billing, determining during an outage whether Electric Service is being provided to a Customer, as well as to establish general Customer usage patterns for the PUD to better identify costs and system needs.
