Outages
Outages
• We have not been able to consolidate our
outage postings to one OASIS site as planned
• We are working to address posting accuracy
and outage path limits on the OATI OASIS
• While we work out the issues with OATI, the
legacy OASIS system is the system of record
for outages on PacifiCorp’s transmission
system

Outage Postings on OASIS
Information on outages on
PacifiCorp’s transmission
system can be found here
on the OATI OASIS web
site.

Outage Postings on OASIS
• The system of record for outages is the Legacy
OASIS outage postings.
• OATI OASIS outage postings are the same
outages as the in the legacy postings but due
to issues we are having with the OATI
formatting may not be accurate or confusing.
Please refer to the Legacy OASIS postings.
• If you have questions concerning posted
outages call Dean Pace at (503)251-5180

Changes to OATI OASIS Postings
• The ability to post all outages on OASIS
• This will allow posting outages that do not affect paths.
• All Prescheduled and forced outages will be posted
identically in all formats.
• Post outage dates and de-rates for the entire outage
whether the outage is the most restrictive outage on
the posted path.
• This will reduce the number of dates and times of the outage which
can cause confusion.
• OATI software to determine which outage is most
restrictive and reduce TTC accordingly.
9
Outage Planning Process
• Project Management will post construction
project outage plans weekly in the Outage
Planning Process folder.
• Construction project outages affecting paths
and generation are scheduled and posted on
the Legacy, OATI outage and in the area
subfolders of the Outage Planning Process
folder.
10
Outage Planning Process
• Outages that do not affect path or generation
are scheduled and posted in the area
subfolders of the Outage Planning Process
folder.
• Information in these reports will contain, new
outages, reasons for outages, and reasons for
outage scheduling changes.
