Re:Case No.IPC-E-11-11
IN THE MATTER OF IDAHO POWER COMPANY’S 2011 INTEGRATED
RESOURCE PLAN (“IRP’9
Dear Ms.Jewell:
By this letter,Idaho Power Company (“Idaho Power”or “Company”)hereby corrects
errors made.in the filed version of its 2011 Integrated Resource Plan (“IRP”).The errors
were discovered during the course of responding to data requests submiffed to Idaho
Power by the Public Utility Commission of Oregon Staff.Specifically,the Company
inadvertently included an amount for an allowance for funds used during construction
(“AFUDC”)twice in the capital cost estimate for the Boardman to Hemingway Project
(“B2H”).When calculating the levelized cost of production for the IRP,AFUDC was
calculated on the estimated Idaho Power share of 28 percent that already included an
estimate for AFUDC.To correct this error,the Company must remove $31 million of
AFUDC from the proposed capital costs of B2H.
This correction impacts three pages of the IRP:page 77 of the main document and
pages 82 and 83 of Appendix C —Technical Appendix.On page 77,the change occurs in
Figure 6.9,which reduces the line labeled as “Transmission-Boardman to Hemingway (450
MW)”from $83 to $81.On page 82 of Appendix C,the change occurs at the line labeled
“Boardman to Hemingway”and at the column labeled “Total Investment $IkW”wherein the
amount is reduced from $580 to $510.Lastly,the change on page 83 of Appendix C
occurs at the line labeled “Transmission-Boardman to Hemingway (450 MW)”and at the
column labeled “Cost of Capital,”which results in a reduction from $19 to $16,and at the
column labeled “Total Cost per MWh,”which results in a reduction from $83 to $81.This
correction does not have a material impact on the results of Idaho Power’s 2011 IRP.
Because portfolio 1-3 Boardman to Hemingway was previously selected as the preferred
122 W.Idaho St.(83702)

portfolio,the removal of the additional AFUDC from the B2H cost estimate lowers the total
cost of the already selected least-cost portfolio.
Idaho Power is attaching hereto the three corrected pages of the IRP.It would be
unduly burdensome and expensive to reprint Idaho Power’s 2011 IRP for the sole purpose
of correcting these three minor errors.That said,Idaho Power will update its website to
include these corrected pages so that on a going forward basis,parties or interested
persons accessing the IRP on-line at the Company’s website will have the most accurate,
up-to-date version of the IRP.
Please call me if you have any concerns.
Verytruyyours,
Jon B.Williams
