No. 29, Tariff No. 101 Eleventh Revised Sheet No. 55-1 IDAHO Issued by IDAHO POWER COMPANY Issued per Order Nos. 34080, 34046, 34071 Timothy E. Tatum, Vice President, Regulatory Affairs Effective – June 1, 2018 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 2.0420 cents per kWh, which is comprised of Category 1 power costs of 1.0708 cents per kWh, Category 2 power costs of 0.8926 cents per kWh and Category 3 power costs of 0.0787 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 2.6902 cents per kWh, which is comprised of Category 1 power costs of 1.4047 cents per kWh, Category 2 power costs of 1.2337 cents per kWh and Category 3 power costs of 0.0518 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 (0.1461) cents per kWh. EARNINGS SHARING Order Nos. 30978, 32424, and 33149 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 2017 earnings were below the prescribed threshold resulting in a credit of 0.0000. Order No. 34071 provides for a direct rate reduction associated with federal and state tax reform.
