Outage Department
• Part of PacifiCorp Transmission and Balancing Authority
real time operations group
• Part of the Reliability Entity for the PacifiCorp BAA
footprint
• Responsible for coordinating the reliability assessment of
outages within the PacifiCorp BAA footprint and with
adjacent BAA’s and the Peak RC
• Facilitates communication of outages, reliability path derates, and scheduling path de-rates as requested by any
entities and as appropriate
• Operates week days, and is supported by real time
operations during other hours
3
Outage Timelines
• Certain lines identified in the Northwest Power Pool planned
outage coordination process require scheduling 45 days prior
to the start of the Outage Month
• 10 working days for lines and equipment 150 kV and above
• 5 working days for lines and equipment 34.5 kV to 150 kV
• 3 working days for distribution outages
• These are minimums and we encourage scheduling outages as
early as possible
• Unplanned/Emergency outages are entered and
communicated as soon as practical
4
Outage Requestors
• Transmission Operators (including but not limited to Pacific
Power and Rocky Mountain Power)
• Balancing Authority Areas
• Generator Operators
• Others working in proximity to energized equipment
5
COMPASS
• Coordinated Outage Management, Planning And
Scheduling System
• Used to create, post and communicate outages
• Identifies which equipment and what type of outage is
occurring
• Can be used to identify transmission or scheduling
limitations associated with the outage
• Can be used to identify potential mitigations or
additional notes pertaining to an outage
• Can be set up to auto-notify via e-mail specific persons
for specific equipment outages
6
Reliability Assessment
• Each outage request is considered by outage coordinators,
accounting for the time of the outage and any other outages
scheduled at that time, as the outage requests are received
• Requestors are contacted by outage coordination for follow
up questions as appropriate
• Transmission and scheduling limitations associated with the
outage are identified prior to posting
• As necessary, further studies or coordination with other
departments or companies is performed
• For outages that present an elevated level of reliability risk,
the requestor is contacted to discuss shortening, moving the
outage or doing work on nights/weekends, etc.
7
Reliability Assessment (continued)
• Outages are posted as soon as practical to allow field and
operations personnel, Transmission Services
departments, and others as much time as possible to
prepare for or comment on the outage
• Further assessments are carried out on month ahead,
week ahead, day ahead, and a real time basis.
• A new assessment of an outage or combination of
overlapping outages can be initiated by any party at any
time
Outage Notifications
• COMPASS has the ability to associate any piece of equipment
with any e-mail recipient. Once a request is made to
associate an e-mail list with a piece of equipment, that party
shall be contacted for all future outages as soon as they are
posted. This feature can not be used for Market affiliates, but
is available to Customer Account Managers
• In addition to specific requests, notification to the PEAK RC,
CAISO, affected TOP’s, GOP’s and BAA’s are made upon all
outage postings or updates
• COMPASS can submit outage information including generic
notes sections or specific TTC information to Transmission
Service providers per their request so they can post on their
OASIS sites
