On April 30, 2025, Rocky Mountain Power, a division of PacifiCorp ("Company"), filed
an application ("Application") with the Idaho Public Utilities Commission ("Commission") for
approval of the capacity deficiency period determination to be used for both Surrogate Avoided
Resource-Based Contracts and Integrated Resource Plan-Based Contracts.
NOTICE OF APPLICATION
YOU ARE HEREBY NOTIFIED that the Company represents that its 2025 Integrated
Resource Plan ("IRP") includes the results of the Company's Capacity Loads and Resources
without Resource Additions for the summer and winter seasons. Application at 3. The Company
states that the capacity balance is generally highest for summer peak loads as the Company is
expected to be deficient in the summer prior to becoming deficient in the winter.Id. at 3-4.
YOU ARE FURTHER NOTIFIED that the Company represents that the 2025 IRP shows
that the Company's load and existing resource balance is less than the Front Office Transaction
limit in 2025 through 2027, but results in a shortfall in the summer of 2028 when the market
purchase limit is assumed to drop to zero due to the implementation of the Western Resource
Adequacy Program, which will not count standard market products towards compliance. Id. at 4-
5. The Company represents that after accounting for adjustments, the first capacity deficiency of
1,077 megawatts occurs in the summer of 2028, and the first winter capacity deficiency of 115
megawatts occurs in 2031. Id. at 6.
YOU ARE FURTHER NOTIFIED that the Company requests that the Commission find
the summer of 2028 as the first capacity deficiency period when capacity payments should be
made to Qualified Facilities under the Surrogate Avoided Resource and IRP avoided cost
methodologies. Id. at 8.
