III. Annual Summary of Substation Outages
of the total number, duration, major causes and effects of outages in each major substation and switchyard.
The report will be prepared in the Denver Office, using ADP procedures, including retrieval of information
previously transcribed from monthly forms PO&M-62.
Copies shall be furnished the Commissioner, Washington Office, and each regional office for distribution as
stipulated by the Regional Director. The report shall be completed and available for distribution by the end

Following is a brief description of the various items of information provided by this report:
The calendar year which the report covers. (There
may be occasions where use of this same basic format
may be desired for summarizing substation outage
information for some period other than a calendar
year, in which event changes could be made as

The projects of which the station is located, arranged

O&M Codes for ADP."
An alphabetical listing of only those major sub-
stations and switchyards on each project which
experienced an outage during the reported period.
Bus Voltage and
The voltage, in kV, of each station or bus reported.
In the event there are several buses of different voltages
in a station, or separate sections of a single-voltage
bus each of which can be individually isolated, entries
on separate lines of the report will summarize outage
data for each reported bus section.
If buses of different voltages in a single station experienced
outages, they will be listed in descending numerical order.
