1. Transmission Reliability Performance Indicators Used by Your Company
Measures based on Circuit and Line Outages:
Circuit Average Outage Frequency Measures (Examples: TADS: TOF;
NERC ALR6-11 – ALR 6-13)FALSE
Length Normalized Outage Frequency Measures (Examples: FOHMY;
TADS: TCOF)FALSE
Outage Duration Measures (Examples: SARI; TADS: SODT, MTTR,
MdTTR)FALSE
Availability Measures (Examples: ASAI%; TADS: APC%, NERC ALR6-15
– ALR 6-16)FALSE
Other ALR Measures FALSE
Other TADS Measures (Examples: PCZero, MTBF, TMCOF) FALSE
Other Measures (please identify in remarks column) FALSE
Customer Impact from Transmission Outages
Transmission SAIFI and/or MAIFI (or contribution to distribution
SAIFI/MAIFI) FALSE
Transmission SAIDI and/or CAIDI (or contribution to distribution
SAIDI/CAIDI)FALSE
Other customer-based measures (please identify in remarks column) FALSE
Delivery Point Impact from Transmission Outages
Delivery Point SAIFI and/or MAIFI FALSE
Delivery Point SAIDI and/or CAIDI FALSE
Other Delivery Point measures (please identify in remarks column) FALSE
2. Load and Generation Loss

MWh Lost (ASIDI) FALSE
Other (please identify in remarks column) FALSE
Generation Loss FALSE
3. What is your system's definition for a "Delivery Point"
High Side of a Transformer FALSE
Low Side of a Transformer FALSE
Variable; an ownership boundary FALSE
Distribution Bus or Feeder Breaker FALSE
We do not collect any delivery point interruption data (please add "why" in
remarks column J)FALSE
4. Delivery Point Impact from Transmission Outages
If you do not utilize or report load loss measures, does your system
consistently collect actual metered load loss (MW, MWh) and can data be
associated with transmission circuit or station outages?
FALSE
Do you record Delivery Point outages caused by station equipment (not
from a line outage) in the same general format as line outages?FALSE
5. Miscellaneous Questions
If your system has a formal process to exclude Major Event Days from
t ransmiss ion performance measures, which method is used:
Six Sigma FALSE
IEEE 1366 Beta Method FALSE
Named Storm/Hurricane FALSE
Other (please specify) FALSE
Can your system identify cable failures for circuits with mixed underground
and overhead construction and report them as a DISTINCT cause code?FALSE
Does your system use consistent component-level sub-causes or codes for
outage causes (e.g., "Line Failure" with sub-causes of structure, conductor,
insulator, shield wire, grounding, etc)?
FALSE
Does your system have interest in component-level sub-causes for
benchmarking or circuit-level analysis?FALSE
Does your system use Transmission Reliability Performance measures for
incentive compensation? If so, which ones (add in remarks)?FALSE
YES
YES
YES
YES
YES
YES

Does your system attempt to quantify the cost (to customers or total
economic losses) of automatic outages?FALSE
6. Station Equipment Data and Benchmarking
Does your system collect data for station outages in a similar format to line
outages (e.g., station ID, equipment type, date/time of event, cause code)?FALSE
What types of station equipment are outage/failure records maintained?FALSE
If you collect station equipment outage records, do they include informationindicating a failure of the equipment itself (i.e., "element initiated", not a
dependent mode outage)?
FALSE
Does your system have a high level of interest in Substation and Station
Equipment benchmarking?FALSE
7. Transmiss ion Benchmarking Forums. Please check current participation:
SGS Transmission Reliability Benchmarking Study FALSE
North American Transmission Forum FALSE
First Quartile Consulting T&D Benchmarking FALSE
Electric Utility Cost Group - Transmission FALSE
International Transmission Operations & Maintenance Study (ITOMS)
(UMS Group)FALSE
Southern Company Transmission Benchmarking (SCTBM) FALSE
Canadian Electricity Association (CEA) (COPE, BES, ERIS, etc) FALSE
Other (specify in remarks) FALSE
YES
YES
YES
