13.08.120: SELECTION AND APPLICATION OF RATE SCHEDULES:
   A.   Selection Of Rate Schedule:
      1.   When a prospective customer makes application for service, the department will, upon request, assist in the selection of the rate schedule appropriate to the customer for the service requested. The selection will be based on the prospective customer's statement as to the class of service desired, the amount and manner of use, and any other pertinent information. This statement will be recorded and filed with the application. The department shall not be liable for any errors in designating the applicable schedule.
      2.   If through error a service agreement is entered into specifying a rate schedule which is not applicable to the class of service taken, on discovery of the error, all bills rendered during the preceding twelve (12) months shall be recalculated in accordance with the lowest properly applicable rate schedule, and any excess paid shall be applied on any outstanding balance owing by the customer or, if no balance is owing, shall be refunded by the department, or any balance due shall be paid by the customer, as the case may be. No adjustments may be made for service provided more than twelve (12) months prior to the date on which adjustment is first requested in writing.
   B.   Distinction Between Residential And Commercial Service: Service rendered through one meter to apartment houses and to recognized rooming and/or boarding houses will be considered commercial service.
   C.   Lighting On Power Schedules: Lighting service will not be supplied under any power rate schedules unless it is so specified in such power rate schedule, and when so supplied the customer will provide and maintain all auxiliary apparatus (transformers, regulators, etc.) that may be necessary. Service supplied to motor generators, any portion of the output of which is used for lighting purposes, shall be considered lighting service.
   D.   Temporary And Standby Service:
      1.   Temporary and standby service shall not be rendered except under a special agreement between the department and the customer unless the temporary service is provided during construction where a permanent service will be established.
      2.   In no event will the department supply power and energy for the purpose of starting or furnishing excitation or other auxiliary service necessary to the operation of any of the customer's generating plant or for parallel operation of the customer's generating equipment with the department's system except under a special agreement between the department and the customer.
