IEEE Benchmarking2011 Results

Based on Distribution Reliability WorkingGroup Meeting in

San Diego, CA

July 24, 2012

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

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

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

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)

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.

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
