Introduction to CROW
Southwest Power Pool’s CROW outage scheduler is used by members of SPP to submit and
coordinate transmission and generation outages.
Outage Coordination Methodology Tables
All of the following tables are referenced from SPP’s Reliability Coordinator Outage Coordination
Methodology.
Outage Priorities
Transmission Outage Priorities
Priority Definition Minimum
Lead Time
Maximum
Lead Time
Planned Equipment is known to be operable with little risk of leading to a
forced outage. As required for preventive maintenance,
troubleshooting, repairs that are not viewed as urgent, system
improvements such as capacity upgrades, the installation of
additional facilities, or the replacement of equipment due to
obsolescence.
14 Calendar
Days
None
Discretionary Equipment is known to be operable with little risk of leading to a
forced outage; however the timeline for submission of Planned
outage priority has passed. Discretionary outages are required to
be submitted at least 2 calendar days in advance. Due to the
shorter lead time, this outage priority has increased risk of being
denied based upon higher priority outage requests.
2 Days 14 Calendar
Days
Opportunity Lead time may be very short or zero. An outage that can be taken
due to changed system conditions (i.e. Generator suddenly offline
for forced outage allows transmission work to be done).
None 7 Days
Operational Equipment is removed from service for operational reasons such
as voltage control, constraint mitigation as identified in an
operating procedure, etc.
None None
Urgent Equipment is known to be operable, yet carries an increased risk
of a forced outage or equipment loss. The equipment remains in
service until maintenance crews are ready to perform the work.
2 Hours 48 Hours
Emergency Equipment is to be removed from service by operator as soon as
possible because of safety concerns or increased risk to grid
security.
None 2 Hours
Forced Equipment is out of service at the time of the request. None 1 Hour

As required for preventive maintenance, troubleshooting, repairs that are not viewed as urgent, system improvements such as capacity upgrades, the installation of additional facilities, or the replacement of equipment due to obsolescence.
14 Calendar Days
None
Opportunity Lead time may be very short or zero. An outage that can be taken due to changed system conditions (ie Loading conditions allow planned work to occur with short lead time).
None 14 Calendar Days
Operational Equipment is removed from service for operational reasons. This could include outages or derates due to reliability directives or other operational concerns not necessarily related to the generating equipment or capability, and outages entered to correct system topology in operating models.
None None
Urgent Equipment is known to be operable, yet carries an increased risk of a forced outage or equipment loss. The equipment remains in service until maintenance crews are ready to perform the work.
24 Hours 48 Hours
Emergency Equipment is to be removed from service by operator as soon as possible because of safety concerns or increased risk to grid security.

Outage Statuses
Status Definition
Proposed The outage request has been saved in the outage scheduler system and remains under the full
revision control until the outage is entered into a Submitted state by the requestor. If the
requestor does not move a proposed request to the submitted status within 30 days of the
planned start date, the outage is automatically Withdrawn. Proposed outage request status
dates DO NOT qualify for outage queuing in conflict resolution. Proposed outage requests
are not provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Submitted The outage request has been submitted into the outage scheduler system and is ready for
review by SPP. The outage requestor does not possess revision control of the outage in this
status. A revision request may be submitted to SPP regarding an outage in Submitted status.
Outage requests in this state are provided to external systems such as NERC SDX/IDC or
SPP’s EMS.
Study SPP will change the status type to Study once the active study process begins. Outage
requests in this state are provided to external systems such as NERC SDX/IDC or SPP’s
EMS.
Preliminary
Approved
Outage requests with Preliminary Approved status have been approved based on long lead
studies and may need additional analysis closer to the planned start date or finalization of an
Operating Guide. Once the restudy is complete or final opguide posted, the outage status is
changed to Approved. Outage requests in this state are provided to external systems such as
NERC SDX/IDC or SPP’s EMS.
Approved Approved state indicates SPP has completed the study process and the outage request is ready
for implementation. Outage requests in this state are provided to external systems such as
NERC SDX/IDC or SPP’s EMS.
Implemented Once the outage request actual start time has been entered, signifying that the outage has
begun, the outage status is changed to Implemented. Outage requests in this state are provided
to external systems such as NERC SDX/IDC or SPP’s EMS.
Completed Once the outage request actual end time has been entered, signifying that the outage has
ended, the outage status is changed to Completed. Outage requests in this state are NO
LONGER provided to external systems such as NERC SDX/IDC or SPP’s EMS.

Facility Naming Conventions
Fundamental Model Characteristics
All bulk electric system equipment in the model in SPP CROW will be associated with a Station.
For purposes of the SPP CROW project, a Station will be defined as all the bulk electric system
equipment located at a geographic location.
For the initial implementation of SPP CROW, the types of bulk electric system equipment that will
be included in the model will be Units, Lines, and Transformers. Other types of bulk electric system
equipment may be included in later upgrades to the SPP CROW system.
Units and Transformers will be associated with (attached to) a Station in the CROW model. A Line
will connect two Stations in the model. Each Line will be listed in CROW as equipment under both
stations it connects to.
Naming Conventions
Stations
Each Station will be given a single common name. This common name will be the name most often
used collectively by transmission owners, transmission operators, and reliability coordinators when
referring to a station.
Station names should be spelled out completely.
If station names contain a direction to distinguish between two stations, the direction will follow the
actual station name.
Directions can be used as an integral part of the station name.
If two stations within the SPP Reliability Coordination area have the same name, the station
operator’s abbreviated name with be added.
Station Name Examples
NW Texarkana
Northwest Texarkana (Preferred)
East Fayetteville, South Fayetteville
Fayetteville East, Fayetteville South (Preferred)
Hugo WFEC
Hugo AEP
From these common names, a 12 character limited station name abbreviation will also be
determined. If the full station name is 12 characters or less, the full name and abbreviated name will
be the same. An appropriate abbreviation of this common name will be critical as station
abbreviations are used frequently in CROW in place of the full station name.
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 12
Equipment
The SPP CROW system allows for three discreet names for each individual piece of bulk electric
system equipment; Lines, Transformers, and Units. These are an SPP EMS NAME, COMMON
NAME, and an ALTERNATE NAME. SPP will determine the SPP EMS NAME for each piece of
equipment by its associated EMS equipment. The equipment Owner/Operator and SPP will
collaborate to determine the most appropriate COMMON NAME. ALTERNATE NAMES can be
set by the equipment Owner/Operator.
Lines
Each transmission line’s Common Name will be the combination of a From Station name and a To
Station name along with the voltage level. Circuit ID numbers will only be used in cases of double
circuits or uncommon equipment configurations. The From and To stations will be placed in
alphabetical order to form the line names.
Line Common Name Examples
Northwest Texarkana – Lydia 345kV
Lydia – Northwest Texarkana 345kV (Preferred)
Transformers
Each transformer common name will be the common name of the station at which it is located along
with the high and low side voltage levels. Circuit ID numbers will only be used in cases of double
circuits or uncommon equipment configurations. Directions can be used in place of circuit ID
numbers to distinguish transformers of the same high and low side voltage level at the same station.
Transformer Common Name Examples
Northwest Texarkana North 345/138kV
Northwest Texarkana South 345/138kV

CROW Outage Scheduler Web GUI Tutorial 13
User Role Setup
The CROW system allows the flexibility to meet each individual company’s business needs related
to the access of transmission and/or generation information of each entity. The system is fully
configurable based on each individual user account. SPP will work with each user to determine the
appropriate access and review authority to preserve code of conduct integrity. The graphic below
outlines the user role model that SPP will follow. Transmission and Reliability roles have the
capability to view or submit outages for all types of equipment within its company. Generation and
Marketing roles are only able to view or submit outages for Units within its company. Please note
that individual users can be set up with read-only access or full outage submittal privileges.

Outage Submissions
The primary focus of SPP members will be outage submission. The following sections will detail
new outage submissions as well as modifications to previously submitted outage request. The outage
submission process will differ depending on the priority selected. For this guide, two types of
priorities will be considered: forced and un-forced. All priorities excluding forced have a similar
submission process; therefore, this tutorial will only cover that process once.
New Request (Forced)
1. The first step in submitting a new outage is to click the New Outage Request button from the
Outage Request Index screen.
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 20
2. Step one creates a new screen under the Outage Request primary tab that displays the
Request Summary tab. This is the screen where equipment will be added and outage request
criteria will be completed. The first step from this screen will be to click Add in order to
select the equipment that is being submitted.
*When submitting a new outage, required fields will be highlighted in yellow.
Select “Add…”
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 21
3. After clicking Add, the Select Circuits/Equipment window appears. This window allows the
user to select the equipment using the drop down lists. Users can select multiple equipment
assets by using the arrows on the right side of the page to add or remove items from the
request. Once the equipment is selected, click OK to return to the Request Summary screen
noting that the equipment has been added to the Equip. Requested table.
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 22
4. For this example we have chosen a Forced outage with the outage cause Unknown. (If upon
further investigation the cause is discovered, then CROW allows for the outage request to be
modified with the updated information. This is addressed in the next section.) We can now
Implement the outage request. It is important to note that since this is a Forced outage, the
only option is to Implement the outage since it should have already started. The default
Planned End Time for a Forced Priority Outage is approximately 24 hours in the future. The
Planned End Time can be updated later as more information about the Forced outage is
known.
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 23
5. Since this is a Forced outage, a new window is displayed that allows the user to log the
actual outage start time before completing the implementation.
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 24
6. Upon successful implementation, the application returns to the Request Summary with a
notification in green that the outage submission was completed successfully. When the
outage is in this state, the user has the option to Request Change to the outage, Save any
changes made to the outage, or Complete the outage by entering the time when equipment
was returned to service. The outage request will also appear in the Outage Request Index.
7. If the outage request conflicts with an existing outage request, the user will receive the
following error indicating the existing outage request.
8. Users should utilize the Request Change button to update the Planned End time or Outage
Cause for submitted outages.
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 25
New Request (Un-f orced)
1. This example will consider a Planned outage to demonstrate the process for submitting un-
forced outages. Begin by clicking New Outage Request from the Outage Request Index page.
2. Step one creates a new screen under the Outage Request primary tab that displays the
Request Summary tab. From here equipment will be added and outage request criteria will be
completed. The first step from this screen will be to click Add in order to select the
equipment that is being submitted.
Select “Add…”

CROW Outage Scheduler Web GUI Tutorial 26
3. After selecting Add, the Select Circuits/Equipment window appears allowing the user to
select the equipment using the drop down lists. Once the equipment is highlighted, click OK
to return to the Request Summary screen noting that the equipment has been added to the
Equip. Requested table.
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 27
4. Once the equipment has been added to the request, the Outage Priority should be selected.
This example specifies a Planned outage priority that will be Continuously out of service for
the time span indicated. Also, a Min. Recall Time of 2 hours has been selected signifying that
it would take at least 2 hours to return this equipment to service if directed to do so. After
selecting Maintenance and Construction for the Outage Cause, notice that Planned outage
requests offer the ability to Save Proposed outage request or Submit the outage request.
Clicking Submit sends the outage request to SPP for analysis. Save Proposed requests are
not visible to SPP and do not have a secured queue date.
5. Upon submittal, a green notification will be displayed at the top of the Outage Request Index
page if the outage request was completed successfully.
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 28
Changing an Existing Request (Forced)
1. To modify an existing outage request, or to notify SPP that the outage has ended by updating
the Planned End Time, start by locating the outage in the Outage Request Index and double-
clicking the request. Notice that when the Request Summary screen is displayed that the
fields are grayed-out indicating that they cannot be changed from this page.
2. Click Request Change to display a new Request Summary that will allow select fields to be
changed. For this example, the outage cause will be updated from Unknown to Equipment
Failure.

3. Next, Submit the change insuring that a green notification is received.
4. This outage request can no longer be modified until SPP staff has updated the approval status
of the change request.
Southwest Power Pool, Inc.
CROW Outage Scheduler Web GUI Tutorial 30
Changing an Existing Request (Un-f orced)
1. To modify an existing outage request, start by locating the outage in the Outage Request
Index and double-clicking the request. For this example, the outage request has been Pre-
approved by SPP. The CROW Web indicates a change in outage request status by
highlighting the request in the Outage Request Index.
