RE: Idaho Power s Integrated Resource Plan , Case No. IPC-06-
After filing Idaho Power s 2006 Integrated Resource Plan on September 29 2006
the Company discovered a number of errors in the Plan document and Technical Appendix
D. Some of these errors were typographical in nature; others were found in tables that had
been propagated in other parts of the IRP. While these errors were not material and did
not change the planning results, Idaho Power wishes to replace the Plan document and
Technical Appendix D with corrected copies so as to avoid potential confusion and better
facilitate the IRP's review.
Please find enclosed eight (8) copies of the revised IRP Plan document and
Technical Appendix D. Please substitute these documents (marked "Revised October 12
2006") and return, recycle or destroy the uncorrected versions filed September 29th. The
Company has also posted a corrected version of these documents on its website at
www. id ahopowe r. com/2006i rp
Thank you for your assistance and patience in this matter. Please contact me at
208-388-5825 if you have questions or if I can help facilitate this in any way.
Sincerely,
/(Dt.0~

2006 OCT 18 PH h: 57As referenced in Idaho Power s 2006 IRP, the maximum average energy savings for
DSM progra~s is 9.0 aMW in the year 2026. However, the 2006 IRP conside

The clarification above also impacts the reported total energy (aMW) contained in the
2006 preferred portfolio. The reported figure of 1 091 aMW would be 1 089 aMW at the
end of the planning period in 2025. Reference to the 1 091 aMW can be found on the
following pages of the 2006 IRP:

Total average energy should be 1 374 aMW, not 1 376 aMW (related to clarification
above)

Implementing the three energy efficiency programs proposed in the 2006 IRP is
anticipated to generate over 780 000 MWh of energy savings per year by 2005-a
savings of 88 aMWannually.
The year "2005" should be replaced with "2025"
