All rate schedules are subject to the following billing adjustments:
204.1 - Sales Tax
All bills shall be adjusted by the amount of any sales tax attributable to the sale of electric service to the member unless the member has previously provided to the Cooperative satisfactory proof of exemption.
204.2 - Over-Billing and Under-Billing
If billings for utility service are found to differ from the Cooperative’s rates for the services being purchased by the member, or if the Cooperative fails to bill the member for such service, or if any meter is found to be outside the accuracy standards established by the American National Standards Institute Incorporated, a billing adjustment shall be calculated by the Cooperative. If the member is due a refund, an adjustment shall be made for the entire period of the overcharges. If an overcharge is adjusted by the utility within three billing cycles of the bill in error, interest shall not accrue. Unless otherwise provided, if an overcharge is not adjusted by the utility within three billing cycles of the bill in error, interest shall be applied to the amount of the overcharge at the rate set by the Public Utility Commission of Texas annually for the calendar year in issue. If the member was undercharged, the Cooperative may back bill the member for the amount that was under billed. The back billing is not to exceed six months unless the Cooperative can produce records to identify and justify the additional amount of back billing or unless such undercharge is a result of meter tampering, bypass, or diversion by the member.
If a meter is found to have an incorrect register or multiplier, the error shall be corrected. Where the error is adverse to the member, the Cooperative shall refund the excess charges for the amount of electricity incorrectly metered over the period of time the meter was used in billing the member. No refund is required from the Cooperative except to the member last served by the meter prior to testing. Where the error is adverse to the Cooperative, the Cooperative may charge the member the undercharge for the amount of electricity incorrectly metered for the period of time the meter was used in billing the member, and if necessary, the Cooperative may receive payment installments over a reasonable period of time. If a meter is found not to register for any period, unless bypassed or tampered with, the Cooperative shall make a charge for units used but not metered for a period not to exceed three months.
204.3 - Power Factor Adjustment
Demand charges may be adjusted if the average power factor is lower than ninety- eight percent (98%). Measured demand may be increased by 1% for each 1% by which the power factor is less than ninety-eight percent (98%) lagging for any period of fifteen (15) consecutive minutes. This adjustment shall not be applied on loads of less than 25 kW.
