2. Micron receives electric utility services from Idaho Power Company ("Idaho
Power" of"Company") as a Special Contract customer, taking service under Schedule 26 and in
the future, pending the Commission's decision in Case No. IPC-E-24-44, under Schedule 28.
Micron is one of Idaho Power's largest customers. In this case, Idaho Power seeks to initiate a
docket to evaluate and develop a record on its Class Cost-of-Service ("CCOS") methodology.
3. As a large customer, Micron has an interest in ensuring Idaho Power's electric
service is reliable and rates are just and reasonable. Micron is a frequent participant in Idaho
Power proceedings, including general rate case proceedings, and was a party to the settlement in
Idaho Power's 2025 General Rate Case that initiated the process resulting in this proceeding. The
record developed in this proceeding will impact Idaho Power's COSS methodology in future
2 IPC-E-25-15.

general rate cases, and ultimately Micron's rates. Micron, therefore, has a "direct and substantial
interest"in this proceeding.3
4. Micron intends to participate herein as a party and, if necessary, to 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 is dependent upon the nature
and effect of other evidence in this proceeding.
5. Granting Micron's Petition to Intervene will not unduly broaden the issues, nor will
it prejudice any party to this case.
6. 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, to present evidence, call and examine witnesses,
present arguments and to otherwise fully participate in this proceeding.
