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 Commission approval of a revised
marginal cost-based energy pricing framework applicable to customers taking service under a
marginal cost-based energy rate, including Micron. Idaho Power would update its marginal-cost
based energy rates consistent with the approved pricing framework in the Company's next
marginal cost-based energy rate update proceeding.
4. Micron has a direct and substantial interest in this proceeding for two reasons.2
First, Micron will pay marginal cost-based energy charges that result from this proceeding under
the Company's Tariff Schedule 28 ("Schedule 28 Special Contract").3 The Company's
'See Idaho Admin.Code 31.01.01.071.
'See Case No.IPC-E-24-44,Order No. 37039(May 8,2026).

MICRON TECHNOLOGY, INC. PETITION TO INTERVENE
IPC-E-26-26

Application, therefore, may modify parts of Micron's Schedule 28 Special Contract rate3.4
Second,Micron actively participated in Case Nos. IPC-E-24-24 and IPC-E-26-08.5 There,Micron
addressed the marginal cost-based rate methodology, and the Commission ultimately directed the
Company to reevaluate Idaho Power's marginal cost-based rate framework in a standalone
proceeding.6 Micron, therefore, has a"direct and substantial interest" in this proceeding.'
5. 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.
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, to present evidence, call and examine witnesses,
present arguments and to otherwise fully participate in this proceeding.
