2021-22
The Commission publishes annually statistics and summary insights on Australian Gas Networks’ operational performance outcomes including network service and reliability performance compared with historical performance, utilising data provided by Australian Gas Networks.
Gas leaks and network interruptions in 2021-22
Of the 6,744 gas leaks reported by the public in 2021-22, 99.8 percent were repaired within the timeframe specified in Australian Gas Networks’ Leakage Management Plan.
Over the past six years, the number of gas leaks reported by the public has exhibited a downward trend with the figure reported for 2021-22 (6,744) being the lowest to date. A similar trend is exhibited for the number publicly reported potential gas leaks attended where no leak was found.
Only a small proportion of Australian Gas Networks’ customers (471,662 as at 30 June 2022) were reported to experience multiple interruptions, representing approximately 0.012 percent of the total customer base.
Only a small proportion of those customers were reported to have experienced long duration interruptions (>12 hours), representing approximately 0.015 percent of the total customer base which is slight decrease from 0.018 percent in 2020-21.
Telephone responsiveness in 2021-22
Of the 10,333 telephone calls to the leaks and emergencies telephone number in 2021-22, 94 percent were answered within 30 seconds. This is consistent with the average historical telephone responsiveness performance of 95 percent.
2020-21
The Commission publishes annually statistics and summary insights on Australian Gas Networks’ operational performance outcomes including network service and reliability performance compared with historical performance, utilising data provided by Australian Gas Networks.
Gas leaks and network interruptions in 2020-21
Of the 6,804 gas leaks reported by the public in 2020-21, 99.9 percent were repaired within the timeframe specified in Australian Gas Networks’ Leakage Management Plan. For comparison, average historical restoration performance is 99.38 percent.
Over the past five years, the number of gas leaks reported by the public has exhibited a downward trend with the figure reported for 2020-21 (6,804) being the lowest to date. A similar trend is exhibited for the number publicly reported potential gas leaks attended where no leak was found.
Only a small proportion of Australian Gas Networks’ customers were reported to experience two or more interruptions, representing approximately 0.011 percent of the total customer base of 466,438 as at 30 June 2021.
