Subject: Case No. RUL-U-26-01
Negotiated Rulemaking: Rules of Procedure of the Idaho Public Utilities
Commission
Dear Ms. Barrios-Sanchez:
Idaho Power Company ("Idaho Power" or "Company") respectfully submits the following
written comments on the proposed changes to IDAPA 31.01.01, Rules of Procedure of the
Idaho Public Utilities Commission ("IPUC", or"Commission"), issued in Case No. RUL-U-26-
01 as part of the negotiated rulemaking process.
Idaho Power Comments
Idaho Power generally supports the Commission Staff's proposed updates. Overall, the
proposed revisions appear to modernize the rules, improve clarity, and support more
consistent administration without materially altering the underlying framework.
Rule 125. Notices to Customers of Proposed Changes in Rates, Paragraph 01, Contents of
Customer Notice, Subpart b.
In response to Staff's question regarding whether customers should be notified of a
proposed rate decrease, Idaho Power recommends that the notice requirement remain in the
rule. Idaho Code Title 61, Chapter 3, consistently refers to "rate changes" and does not
distinguish between increases and decreases. Retaining the notice requirement for both
upward and downward rate adjustments is therefore consistent with the statutory framework
and avoids creating ambiguity regarding when customer notice is required.
From a regulatory policy perspective, providing notice of both increases and decreases
promotes transparency, customer awareness, and consistent utility practice. A rate decrease
may still affect customer bills, rate design, billing determinants, or the manner in which

charges are presented. Maintaining a uniform notice obligation for all proposed rate changes
also reduces the risk of interpretive disputes and supports predictable application of the
Commission's customer notice requirements.
Idaho Power appreciates the opportunity to provide comment in this proceeding. If you
have any questions, please contact Senior Regulatory Analyst Ashley Herrera at 208-388-
2656 or aherrera(a-).idahopower.com.
Very truly yours,
