IEEE Benchmark Year 2014Results for 2013 Data

July 29, 2014 General Meeting

Distribution Reliability Working Group

Washington D. C.

Background to IEEE DRWG BenchmarkStudy

1. Initiated in 2003, conducted annually

2. Participants are anonymous with key identifier toretain anonymity

3. Participation list is not revealed to anyone

4. Each participant can choose to share their results

5. No inference is made about good or bad reliability

6. Intended to provide information for users to assesstheir performance relative to peers

3

Benchmarking

• Using annual key metrics (SAIDI, SAIFI and CAIDI) to assessperformance of a system may be useful, however, needs to betempered

• DRWG Study attempts to identify various aspects that couldcause a difference in reported metrics

• Data may not be directly comparable, since– Data collection & system differences exist

– Certain exclusion differences can occur

• IEEE 1366-2003/2012• 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 data collection issues orother reasons

The following slides…

• Show company performance using the IEEE 2.5 Beta method tosegregate data into:

– Day-to-Day operating Indices vs.

– Performance considering the whole customer experience (All)

– Separate data collected to evaluate impact of transmission(WOF) and both transmission and planned outages (WOP)

– Segregation by transmission (feed), planned and distribution

• To date more than 200 companies have participated in ourbenchmarking at sometime.

Areas We’ve Discussed & Acted On

Need to capture total number of distribution circuits

Additional details about overhead and underground circuitmileage

• Consider data which helps the industry back into a scorecardfor storm performance

• Daily beta variable calculations for future study

33

Areas To Analyze: Brainstorm

• Benchmark Data Collected:• Now that we have total number of distribution circuits, are there

performance trends we can see?

• Planned and transmission outage impacts and variabilityacross participants…is there a best practice or are we just notgetting equivalent data?

• Major Events• Persistence of major events for each utility

• Daily beta variable calculations

• Consider data which helps the industry back into a scorecardfor storm performance
