Tatum, Vice President, Regulatory Affairs Effective – June 1, 20201 1221 West Idaho Street, Boise, Idaho SCHEDULE 55 POWER COST ADJUSTMENT APPLICABILITY This schedule is applicable to the electric energy delivered to all Idaho retail Customers served under the Company’s schedules and Special Contracts. These loads are referred to as "firm" load for purposes of this schedule. BASE POWER COST The Base Power Cost of the Company's rates 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: Category 1, Category 2 and Category 3. Category 1 power costs include the sum of fuel expense and purchased power expense (excluding purchases from cogeneration and small power producers), less the sum of off-system surplus sales revenue and revenue from market-based special contract pricing. Category 2 power costs include purchased power expense from cogeneration and small power producers. Category 3 power costs include demand response incentive payments. The Base Power Cost is 2.0361237 cents per kWh, which is comprised of Category 1 power costs of 1.067712 cents per kWh, Category 2 power costs of 0.8900846 cents per kWh and Category 3 power costs of 0.078479 cents per kWh. PROJECTED POWER COST The Projected Power Cost is the Company estimate, expressed in cents per kWh, of the Category 1, Category 2 and Category 3 power cost components for the forecasted time period beginning April 1 each year and ending the following March 31. The Projected Power Cost is 2.84099258 cents per kWh, which is comprised of Category 1 power costs of 1.49915174 cents per kWh, Category 2 power costs of 1.28883557 cents per kWh and Category 3 power costs of 0.053027 cents per kWh. TRUE-UP AND TRUE-UP OF THE TRUE-UP The True-up is based upon the difference between the previous Projected Power Cost and the power costs actually incurred. The True-up of the True-up is the difference between the previous year’s approved True-Up revenues and actual revenues collected. The total True-up is (0.29711222) cents per kWh. EARNINGS SHARING Order Nos. 30978, 32424, and 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 201920 earnings were below the prescribed threshold resulting in a credit of 0.0000 cents per kWh.
