SAIDI / SAIFI Benchmark Report
Reliability Metrics Translated for Leadership
SAIDI / SAIFI Benchmark Report
SAIDI and SAIFI measure outage duration and frequency, but numbers alone do not drive decisions. EPG Solutions turns reliability indices into executive-ready intelligence that explains what changed, why it matters, and what leadership should consider next.
What SAIDI and SAIFI Actually Tell Leadership
| Metric | What It Measures | Business Translation |
|---|---|---|
| SAIDI (System Average Interruption Duration Index) | Average total outage minutes per customer per year | How long your customers are without power compared to peer utilities |
| SAIFI (System Average Interruption Frequency Index) | Average number of sustained interruptions per customer per year | How often your customers experience outages relative to comparable systems |
| CAIDI (Customer Average Interruption Duration) | Average restoration time per interruption event | How fast your crews restore service once an outage occurs |
Most utility boards see these numbers in annual reports but lack the peer context to interpret them. A SAIDI of 120 minutes might be excellent for a rural cooperative but poor for an urban municipal. EPG benchmarks provide that context.
Beyond the Index: What a Strong Reliability Benchmark Covers
A useful SAIDI/SAIFI benchmark does more than rank your utility against an average. It explains the operational story behind the numbers and helps leadership make informed decisions about where to invest.
What EPG Reliability Reports Include
- Year-over-year trend analysis with major event context
- Peer comparison by utility size, geography, and system characteristics
- Outage cause breakdown: equipment failure, weather, vegetation, third-party damage
- Crew response and restoration time benchmarks
- Infrastructure age and replacement cycle analysis
- Customer impact assessment and service territory risk mapping
EPG does not produce generic reports from national databases. Every reliability benchmark is built around your specific utility, your peer set, and the questions your leadership team needs answered.
Why EPG Solutions
EPG specializes in electric utility intelligence. Our team understands reliability engineering, outage management, and the regulatory context that shapes how SAIDI and SAIFI are calculated, reported, and interpreted.
- Technical depth: We understand IEEE 1366, major event day exclusions, and how calculation methodology affects comparisons
- Leadership translation: Every report is written for decision-makers, not reliability engineers
- Peer relevance: Benchmarks built from utilities that actually match your system, not national averages
