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

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.
