IEEE Benchmark Year 2017 Results for 2016 Data

2017 General Meeting

Distribution Reliability Working Group

Chicago, Illinois

2

Background to IEEE DRWG Benchmark Study

1. Initiated in 2003, conducted annually

2. Participants are anonymous with key identifier to retain 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 assess their performance relative to peers

7. Called the 2017 Study (for 2016 Results)

Benchmarking • Using annual key metrics (SAIDI, SAIFI and CAIDI) to assess

performance of a system may be useful, however, needs to be tempered

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

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

– Certain exclusion differences can occur, although we strive to have the differences minimized

• IEEE 1366-2003/2012 • addresses data issues by clearly defining the rules (i.e. what data should be

excluded)

• It DOES NOT address the data collection issues

• Companies may not report all forms of outages, due to data collection issues or other reasons
