Network Reliability Reporting
Report how often and how long customers lose supply, using index definitions the regulator sets, so reliability is visible, comparable and tied to targets and incentives.
- SAIDI
- SAIFI
- Customer Minutes Lost
- Customer Interruptions
In scope
- Interruption data capture and validation
- Reliability index calculation and annual filings
- Major event day classification and exclusion
- Worst-performing circuit identification
Out of scope
- Asset failure rates and reliability for maintenance decisions (see BC-680.40.40)
- Recording interruptions as outages happen (see BC-1530.20.40)
- Declaring an event level to drive the response (see BC-1580.50.10)

- BC-1580.20.10Interruption Data ValidationConfirm each recorded interruption has accurate start, end, cause and customers affected before it feeds any reported index.
- BC-1580.20.20Reliability Index CalculationCalculate duration, frequency and restoration indices by circuit, region and year from validated interruption records.
- BC-1580.20.30Major Event ClassificationDecide after the fact which days count as major events under the regulator's method and report them separately from normal performance.
- BC-1580.20.40Worst Circuit ReportingIdentify the circuits and customers with the poorest reliability and report the remediation planned for each.
