IEEE Benchmarking2011 Results
Based on Distribution Reliability WorkingGroup Meeting in
San Diego, CA
July 24, 2012
2
Background to IEEE Benchmarking
Initiated in 2003 and conducted annually
Participants are anonymous with keyidentifiers assigned to retain anonymity
Participation list is not revealed to anyone
Each participant can choose to share theirresults
No inference about “good” or “bad” reliability
Intended to provide information to allowparticipants to assess their performancerelative to others
3
Benchmarking
Even in this study…
Data is Never exactly the same!
Two main reasons for differences:– Data Collection Process/System Differences
– Segmentation Differences (Basis)
IEEE 1366-2003– addresses data basis issues by clearly defining the rules.
– It DOES NOT address the data collection issues
– Companies may not report all forms of outages, due to datacollection issues or other reasons
4
The following slides…
Show company performance using the IEEE 2.5 Betamethod to segregate data into:
1. Day-to-Day operating Indices (IEEE)
2. Performance considering the whole customerexperience (All)
3. New feature…Performance looking only atdistribution system outage events (WOF)– WOF is to designate “without feed” which is to distinguish those
outages upstream of the distribution substation high-sidedisconnect, typically designated as Source or Supply outagecauses
– Applies same major event days to calculate comparableperformance of system when transmission outage events areremoved
– 86 of 90 companies supplied data at this level

Customer density, use of step restoration, computerizedreporting system, connected model, level of devices recorded.
98% of utilities use step restoration
99% of utilities use a computerized reporting system
91% of utilities use a connected model

Classification of Respondents’ Systems
2011 Survey
At January meeting we agreed that greater focus on qualitysystem classification would occur…some companies took thatto heart, however there are still apparent flaws in some of theentries
Urban, Suburban,Rural
Rural <= 50 cust/mi (31cust/km)
Suburban > 50 cust/mi<150 cust/mi
Urban >= 150 cust/mi(93 cust/km)
7
Classification of Respondents
69,805,231customers represented in US &Canada
Small, Medium, Large
Small =< 100,000 customers
Medium >100,000 and <1,000,000 customers
Large >= 1M customers
2011 Survey
8 Small companies
55 Medium companies
27 Large companies

Total Performance Data Review
Reliability metrics which include the impact ofmajor events can also be revealing.
This data can show regional impacts ofmajor events (generally associated withweather events)
How heavily major events can impactoutage restoration metrics (CAIDI) and
The substantial impact that major eventshave on cumulative outage duration (SAIDI)
The following slides show data without segmentation.

Trends for Utilities providing data
CAIDI IEEE SAIDI IEEE SAIFI IEEE
Summary
More advancements could be developed such asthese identified by Working Group:
Vary bar widths as a function of customers servedby each utility (may be a challenge forspreadsheet’s graphics)
Try a colorized version based on utility size ratherthan region
Analyze a subset which reflects consistentparticipation in study
Review CAIDI calculations to ensure propersegmentation of transmission outages
