IPUC Data Request 1
IPUC Data Request 1
Please identify all filings related to and/or dependent on IRP approval and
describe any potential impacts on those filings with an extension of the IRP
timeline.
Response to IPUC Data Request 1
The Company is aware of two filings ordered by the Idaho Public Utilities
Commission (IPUC) that utilizes Integrated Resource Plan (IRP) data: (I) Order
No. 32697 requires the Company to update its capacity sufficiency / deficiency
period, used to identify when new qualified facilities are eligible for capacity
payments; (2) Order No. 30497 requires the Company, in conjunction with its IRP
planning process, to address wind and solar integration costs as a discrete part of
its plan. The updated wind and solar integration study is filed for IPUC approval
in a separate docket.
An extension to the timeline of PacifiCorp's 2021 IRP would delay both filings.
While the IRP extension would delay those subsequent filings, IPUC approval for
the delay of those filings is not required as the due dates are triggered by the date
of an acknowledged IRP.
