RE NOTICE OF PACIFICORP'S INTENT NOT TO FILE A 2019 INTEGRATED
RESOURCE PLAN UPDATE
Dear Ms. Hanian:
Order No. 22299 rcquJred Rocky Mountain Power, ("Company"), to file biennial Integrated
Resource Plans, ("IRPs"). That filing requirement was reaffirmed in Order No. 27835 when the
Commission directed the Company to file an IRP in December 2000 and every two years
thereafter. Later Order No. 30262 authorized the Company to file all future IRPs by the last
business day of March on a biennial basis beginning in 2009. Order No. 34404 authorized
PacifiCorp's postponed filing of the 2019 IRP on October 1.8,2019, rather than the last business
day of March.
While not required, PacifiCorp has traditionally filed an IRP Update within one year of filing its
biennial IRP. PacifiCorp respectfully provides notice that it does not plan on filing a 2019 iRP
Update to provide time to focus on the acknowledgement and acceptance of the 2019 IRP and
preparation ofthe 2021 IRP.
The Company does not anticipate receiving orders or written acknorryledgements ofthe 20l9IRP
from all of the commissions before March 31, 2020, when it would typically file the 2019 IRP
Update. If these orders required the Company to provide certain information in the 2019 lRP
Update, the Company probably wouldn't have time to comply with those orders. Additionaliy,
PacifiCorp will be preparing for the 2021 IRP with preJRP studies, processes, and preparations
for the public-input process that begins around June 2020 in order to file the 2021 IRP at the end
of March 2021.
The Company needs time to evaluate and hopefully implement new and improved modeling
software. During the 2019 IRP cycle the Company experienced delays due to modeling issues
despite being able to improve and expand upon the capabilities of its existing modeling software.
The continuous IRP modeling cycle makes it nearly impossible to conduct an evaluation and
implementation of software updates. Not filing the 2019 IRP Update would provide a small
window to pursue this much needed effort.
