Said, General ManagerVice President, Regulatory Affairs Effective – June 1, 20101 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 two categories; Category 1 and Category 2. 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. The Base Power Cost is 1.5003606 cents per kWh, which is comprised of Category 1 power costs of 1.05731163 cents per kWh and Category 2 power costs of 0.443043 cents per kWh. PROJECTED POWER COST The Projected Power Cost is the Company estimate, expressed in cents per kWh, of the Category 1 and Category 2 power cost components for the forecasted time period beginning April 1 each year and ending the following March 31. The Projected Power Cost is 1.64075937 cents per kWh, which is comprised of Category 1 power costs of 1.18920.8882 cents per kWh and Category 2 power costs of 0.4515 7055 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 (0.1710074) cents per kWh. RECOVERY OF DEMAND-SIDE MANAGEMENT (“DSM”) DEFERRAL BALANCE Final Order No. 32217, allows the Company to recover $10 million of DSM expenditures that were previously incurred and booked to the Energy Efficiency Rider balancing account. Pursuant to Order No. 32217, Tthe recovery of the $10 Million DSM balance amount has been allocated to individual rate classes based on each class’s proportion of total base revenues during the PCA year, as shown below.
