RE: Case No. PAC-E-13-02
In the Matter of Rocky Mountain Power's Application for an Order Authorizing
Changes in Depreciation Rates Applicable to Electric Property
On November 18, 2013, the Idaho Public Utilities Commission approved an all-party stipulation
in Case No. PAC-E-13-02. Paragraph 28 of the Settlement Stipulation states:
The Stipulating Parties agree the Company will implement a reporting system to
keep the Stipulating Parties and the Utah, Idaho and Wyoming Commissions
informed regarding any matters likely to have implications regarding potential
stranded costs of generating assets. The Company will propose a reporting
method by no later than December 31,2013.
Per this commitment, Rocky Mountain Power submitted a proposal on December 20,2013 to
implement a reporting system that provides information regarding three scenarios which the
Company has identified as having significant implications on the Company's depreciation
expense. Because no party filed comments on the Company's proposal, the Company hereby
submits the filing as originally proposed.
On or before March I of every year, the Company is to file a letter containing the following
information, if appl icable.
l) Any proposed early steam generation unit retirement
a. Plant name
b. Date placed in service
c. Current net book value
d. Original retirement date
e. Proposed early shutdown date
f. Reason for early shutdown

2) Major steam plant capital additions over $100m that impact the depreciation of the
unit
a. Project name
b. Planned in-service date
c. Planned retirement date
d. Planned addition amount to plant in service
3) Any completed external studies regarding plant decommissioning which result in
significant changes (a change of over 25 percent) to the amount previously projected
in the last approved depreciation rates.
a. Plant site
b. Estimated costs
The Company files this letter in compliance with the established reporting system and states that
there are no significant chanees that impact the Company's depreciation expense and would
require identification at this time.
Questions regarding this filing may be directed to Ted Weston at [phone].
