Idaho Power Company’s General Rate Case
Dear Ms. Noriyuki:
Enclosed for electronic filing, please find Idaho Power Company’s Supplemental
Response to the Second Production Request of the Commission Staff to Idaho Power
Company.
Due to the collectively voluminous confidential and non-confidential information
provided in response to data requests in this case, the Company is posting the
attachments to these requests to the secure FTP site to allow parties to view the
requested information remotely unless otherwise noted in the response. Because certain
attachments contain confidential information, the FTP site is divided between confidential
and non-confidential information.
The login information for the non-confidential portion of the FTP site has been
provided to all parties that have intervened to date. The login information for the
confidential portion of the FTP site has been provided to the parties that have executed
the Protective Agreement in this matter.
If you have any questions about the attached filing, please do not hesitate to
contact me.
Very truly yours,
Lisa D. Nordstrom
