IPC-03- APPLICATION Idaho Power Company (Idaho Power or Company), pursuant to I.C. 9 61-525 applies to the Idaho Public Utilities Commission (Commission) for authority to institute revised depreciation rates for the Company s electric plant in service. The last major changes to the Company s depreciation rates occurred March 18 , 1993 as a result of Order No. 24739 issued in Case No. IPU-92-23. The Company seeks to revise depreciation rates applicable to its electric plant in service.In support of this Application, Idaho Power presents the following: APPLICATION - Page Idaho Power is an Idaho Corporation , whose principal place of business is 1221 West Idaho Street, Boise , Idaho 83702 II. Idaho Power operates a public utility supplying electric service in Southern Idaho and Eastern Oregon. Idaho Power is subject to the jurisdiction of this Commission in Idaho and in Oregon is subject to the jurisdiction of the Oregon Public Utility Commission. Idaho Power is also subject to the jurisdiction of the Federal Energy Regulatory Commission (the "FERC" III. The Company is not requesting a change in its electric rates. This request is for an accounting order approving the revised depreciation rates for the Company to apply prospectively to its depreciable plant in service. IV. The revised depreciation rates are based on the results of a detailed depreciation study authorized by the Company and conducted by Gannett Fleming, Inc. relative to Idaho Power s electric plant in service as of December 31 2001. The study updates net salvage percents and service life estimates for all plant assets. The study is Exhibit 1 to the testimony of Gannett Fleming Inc.'s Vice President , John Spanos. The current depreciation rates for Idaho Power have been applied to the investment in each primary and sub plant accounts.These depreciation rates are based on the straight line , remaining life method , location life basis (life span technique) APPLICATION - Page 2 for production plant and the straight line, remaining life method for transmission and distribution plant and amortization of certain general plant accounts.A summary schedule detailing the December 31 , 2001 original plant cost , depreciation accrual amount and rate is set forth in Attachment 1. VI. The proposed depreciation rates for Idaho Power (Attachment 1) are based on plant accounting data available as of December 31 , 2001. Gannett Fleming was responsible for identifying and measuring changes , and recommending depreciation rates. The proposed depreciation rates are based on the straight line, remaining life method, average service life procedure for all electric plant. VII. Based on depreciable electric plant in service at December 31 , 2001 of 900 657,420 , the requested changes in depreciation rates would result in a 994 021 increase in the total annual depreciation expense.The Company believes the proposed depreciation changes using the average service life procedure are reasonable and appropriate. VIII. Gannett Fleming, in conducting the depreciation study recommended the use of the Equal Life Group Procedure (ELG). The Company requested that Gannett Fleming prepare an alternative to its recommendation due to the impact on revenue requirement of the Company utilizing the ELG procedure.That alternative recommendation developed depreciation rates based on the Average Service Life Procedure. While the APPLICATION - Page Company is proposing Average Service Life Procedure in this proceeding it concurs that the preferred procedure is ELG. IX. Simultaneous with the filing of this Application, the Company has filed its direct case consisting of the testimony and exhibits of witness John J. Spanos. The Company stands ready for immediate consideration of this Application , if it is the Commission determination that a hearing should be held.
