2. Micron receives electric utility services from Idaho Power Company ("Idaho
Power"or the"Company")as a Special Contract customer,taking service under Schedules 26 and
28. Micron is one of Idaho Power's largest customers.
3. In this case, Idaho Power's Application seeks a Commission order (1) approving
updated electric plant-in-service depreciation rates effective January 1, 2028; and (2) authorizing
amortization accounting treatment consistent with Federal Energy Regulatory Commission
("FERC") Order No. 898. The Company's Application would not affect Idaho Power's rates
currently in effect. Rather, the Company would increase retail electric rates consistent with the
new depreciation rates in a subsequent proceeding.
4. Micron has a direct and substantial interest in this proceeding.2 Micron is one of
the Company's largest customers, and relies on the Company for reasonable rates and reliable

electric service. The Company's Application seeks to raise most electric plant-in-service's
depreciation rates, resulting in an approximately $32.3 million annual increase to the Company's
authorized depreciation expense. Thus, the Company's Application, if granted, would
significantly impact Micron's electric rates and energy costs. Micron, therefore, has a"direct and
substantial interest" in this proceeding.3
5. Micron intends to participate herein as a party and, if necessary, file comments,
introduce evidence, cross-examine witnesses, call and examine witnesses, and be heard in
argument. The nature and quantity of evidence Micron will introduce depends on the nature and
effect of other evidence in this proceeding.
6. Granting Micron's Petition to Intervene will not unduly broaden the issues,nor will
it prejudice any party to this case.
7. Without the opportunity to intervene, Micron would be without adequate means to
participate in this proceeding that will have a material impact on its electric service.
WHEREFORE,Micron Technology,Inc.respectfully requests that the Commission grant
its Petition to Intervene in this proceeding and to appear and participate in all matters as may be
necessary and appropriate;and,if necessary,present evidence,call and examine witnesses,present
arguments and otherwise fully participate in this proceeding.
