POWER COST ADJUSTMENT Monica Barrios-Sanchez Secretary
APPLICABILITY
This schedule is applicable to the electric energy delivered to all Idaho retail Customers served
under the Company's schedules and Special Contracts listed within this schedule. These loads are
referred to as "firm" load for purposes of this schedule.
BASE POWER COST AND PROJECTED POWER COST
The Base Power Cost of the Company's rates, expressed in cents per kWh, is computed by
dividing the sum of the Company's power cost components by firm kWh sales. The power cost
components are segmented into three categories as described in the table below:
The Projected Power Cost is the Company estimate, expressed in cents per kWh, of the power
cost components for the forecasted time period beginning April 1 each year and ending the following
March 31.
BALANCING ADJUSTMENT
The Balancing Adjustment is based upon the differences between previous Projected Power Cost
and the power costs actually incurred. The Balancing Adjustment is 0.5946 cents per kWh.
EARNINGS SHARING
Order Nos. 30978, 32424, 33149, and 34071 directed the Company to share a portion of its
earnings above a certain threshold with customers through the annual Power Cost Adjustment. The
Company's 2023 earnings were not above the prescribed threshold resulting in a credit of 0.0000 cents
per kWh.

POWER COST ADJUSTMENT
The Power Cost Adjustment (PCA) is the sum of: 1) 95 percent of the difference between the
Projected Power Costs in Category 1 and the Base Power Costs in Category 1; 2) 100 percent of the
difference between the Projected Power Costs in Category 2 and the Base Power Costs in Category 2;
3) 100 percent of the difference between the Projected Power Costs in Category 3 and the Base Power
Costs in Category 3;4)the Balancing Adjustment; and 5) Earnings Sharing. The following table calculates
the rates for Categories 1, 2 and 3.
The following table shows the determination of PCA rates for Categories 1, 2, and 3:
