Applications for adjustments to base period energy or for scheduling curtailments shall be filed with the utility adjustment committee.

(1) Adjustments to base period energy shall be based on the following criteria:

(a) for major use customers:

(i) suggested adjustments to base period energy of exist-ing major use customers shall be made by the utility, taking into account installed increases or decreases in normal load;

(ii) customers becoming major use customers in the period after the base energy period by reason of increased usage shall have their base period energy calculated by the utility on the basis of the projected usage before curtailment; and

(iii) the state appeals board shall grant, deny or modify base period energy adjustments as suggested by the utility and requested by the applicant major use customer.

(b) for non-major use customers adjustments to base period energy shall be made by the utility adjustment committee. A customer requesting such adjustment shall supply the utility with a description of where additional energy requirements have occurred and the reason why such additional energy consumption cannot be avoided during the curtailment period.

(2) Customer-owned generating facilities may be used to meet the customer's energy requirements during periods of mandatory curtailment, provided that the energy provided by the utility to such customer is reduced by not less than the percentage curtailment required.

(3) Adjustments to scheduling of curtailment are provided for as follows:

(a) A customer may schedule energy curtailment in any period and in any manner to minimize economic costs, hardships or inconvenience, provided that the required energy curtailment, if determined on other than a daily basis, shall be assured within each billing period. However, if a utility can shift energy saved in a current period within the projected shortage period, then a customer of such utility may schedule such future period curtailment in the future period. Any such scheduling shift shall be approved by the state appeals board.

(b) Major use customers who would otherwise be subject to curtailment at more than one location in the region, may schedule curtailment among multiple locations in the region in any manner which assures the required curtailment level will be achieved. No such scheduling among locations may go into effect until the user provides to the utility and the state appeals board, in writing:

(i) an outline of the proposed curtailment schedule;

(ii) a statement of the manner in which the total curtailment level will be calculated and assured;

(iii) a description of the effect of the schedule on employees and customers; and

(iv) if the proposed schedule also shifts the energy load from one utility to another, each affected utility must consent to the proposed schedule.

(4) The state appeals board shall submit its recommendations derived under subsection 111 and (3) regarding adjustments to base period energy and for scheduling of curtailments to the governor for determination.
