Said, General Manager, Regulatory Affairs Effective – June 1, 2010 1221 West Idaho Street, Boise, ID 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 1.5003 cents per kWh, which is comprised of Category 1 power costs of 1.0573 cents per kWh and Category 2 power costs of 0.4430 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 1.6407 cents per kWh, which is comprised of Category 1 power costs of 1.1892 cents per kWh and Category 2 power costs of 0.4515 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 0.1710 cents per kWh. POWER COST ADJUSTMENT The Power Cost Adjustment 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; and 3) the True-ups. The monthly Power Cost Adjustment applied to the Energy rate of all metered schedules and Special Contracts is 0.3114 cents per kWh. The monthly Power Cost Adjustment applied to the per unit charges of the nonmetered schedules is the monthly estimated usage times 0.3114 cents per kWh. EXPIRATION The Power Cost Adjustment included on this schedule will expire May 31, 2011.
