PJM List of Transmission Outage (TXT)
NERC Alert Transmission Outages (TXT)
The Transmission Facilities Outage List (TFOL) is a text report which lists outaged facilities within the PJM Markets footprint. Below is a description of the data in each of the three sections of the report (current, scheduled and planned). It includes an explanation of each column in the sections.
Please note, another version of the scheduled and planned sections of this report, which is filterable by column and includes XML download capability, is available via the eDART – Transmission Outage Ticket application. Also included is a historical report which details past outages. Access to that version of the report requires a Generic account in eDART.
| Current outages are obtained from the PJM Energy Management System and depicts all outageable facilities that are currently out-of-service on the PJM system. This list of transmission outages may be comprised of a combination of unplanned and scheduled transmission outages. Unplanned transmission outages are typically outages required to perform emergency repair in order to protect equipment or are a result of inadvertent trippings of facilities. Current outages may also consist of scheduled outages, which were analyzed and approved by PJM in advance and are out-of-service to perform required maintenance in order to preserve overall system reliability. |

| Ticket |
eDART – Transmission Outage Ticket number where outaged facility is included. This ticket number can be used to reference the outage information in the Scheduled section where more information about the outage will be contained.If "0" is shown there is no ticket in eDART for this outage and it will not be included in the Scheduled Outage section. |
| Facility Name |
This field is broken up into four parts.The equipment types are defined as the following: - BRKR - Breaker or Disconnect
- CAP - Capacitor
- LINE - Line
- PS - Phase Shifter
- SD - Series Device
- XFMR - Transformer
The second is the eight character abbreviation for the station for which the facility resides. For lines the station shown will usually be the first alphabetic station name. (Ex. A line going from station ABCDEFGH to IJKLMNOP would be listed under ABCDEFGH.) The third is the Voltage level. For transformers this is the high side voltage. The fourth field is the equipment name. It is a 32 character name which describes the facility. |
Scheduled Outages are obtained from the eDART – Transmission Outage Ticket application and depicts all reportable facilities that have been submitted with more detail then is available in the Current Section. Transmission operators request transmission outages in order to perform the necessary normal maintenance on the transmission system to preserve overall system reliability or in case of trippings to notify PJM OI of the outage. When the outage requests are received by PJM OI, the status column will appear as "Received." Once PJM OI performs an analysis to ensure the requested transmission maintenance does not adversely effect system reliability, the outage will be approved and the status column will appear as "Approved." Due to the uncertainty of system conditions, the possibility exists that transmission maintenance can be canceled even after a transmission outage request is approved.In the case of a tripping or other type of emergency outage the status of the ticket may immediately go to "Active" upon PJM OI receipt of outage ticket. |

| Start Date/Time |
Date and time the outage is scheduled to begin. The date is in the DD-MMM-YYYY format. The time is in military format.
|
| End Date/Time |
Date and time the outage is scheduled to end. The date is in the DD-MMM- YYYY format. The time is in military format.
|
| Open/Closed |
Denotes if the facility is in or out of service. In service (closed) facilities are denoted by the letter “C.” Out of service (open) facilities are denoted by the letter “O.” |
| Status |
The current status of the ticket in the eDART - Transmission Outage Ticket application. Only tickets with the statuses listed below are displayed: - Received – Outages has preliminary approval from the PJM Power Dispatchers.
- Revised – Submitting company recently made changes to the ticket after it had previously been in the status of Received or Approved.
- Approved – Either the following could be the case for this outage:
- Outage has been studied and given final approval by the PJM OI in the case of normal tickets. Emergency tickets in this status may have been given this status immediately upon receipt by the PJM OI.
- Outage has a “Daily” Outage Type which has been either ended for the day,has not yet started for the day or may not start for the day. (See Outage Type column description for more details.) - Active – Outage is currently in progress.
- Completed – Outage has been completed within the last six hours.
- Cancelled - Outage had been cancelled within the last six hours.

Timestamp for when ticket was last updated in the eDART – Transmission Outage Ticket Application. This update may have only been a change in status. |
| Outage Type |
Type of outage. There are two main types Continuous and Daily. - Continuous outages are tickets which will be Active for the life of the Start and End. The two Continuous types are Continuous and Continuous – Not Including Weekends. The only difference between the two is that in the latter the outage does not occur during the weekend.
- Daily outages start and stop each day for the life of the ticket. For each day the Start Time column denotes when the ticket is scheduled to start each day. The End Time column denotes when the ticket is scheduled to end each day. The three Daily types are Daily – Including Weekends (tickets scheduled for Sunday – Saturday), Daily – Not Including Weekends (tickets scheduled for Monday – Friday), and Daily - Weekends Only (tickets scheduled for Sunday and Saturday).

Reason and/or description of job. There will be one or many "Causes". Causes are selected from a canned list to better describe scope of outage. |
| Planned Outages are obtained from the eDART – Transmission Outage Ticket application and depicts all reportable facilities where routine periodic maintenance is scheduled for a period encompassing the next 13 months. PJM OI evaluate the outage requests and place outage requests on the planned transmission outage schedule, if they are determined to be consistent with system reliability. PJM OI periodically review all submissions of planned transmission outages and consider the effect of proposed transmission outages upon the integrated operation of the bulk power electric supply system.Start/Stop dates and times of planned maintenance outages are much more uncertain than that of scheduled maintenance outages due to the advance time notification of the initial Planned Outage request.As these tickets get closer to the date they are scheduled to run they will be moved into the Scheduled section if they will become actual event. |
