SAIDI/SAIFI Calculator
OperationsCompute standard IEEE reliability metrics from outage records. Input your outage data and get SAIDI, SAIFI, CAIDI, and related indices instantly.
Example questions you can ask:
- "Calculate SAIDI from these 5 outages affecting 10,000 customers"
- "What's my SAIFI if I had 12 outages this year?"
- "Compare my CAIDI to industry benchmarks"
