OPERATIONAL EXCELLENCE
WORLD-CLASS NETWORK PERFORMANCE
Singapore continues to experience the fewest and
shortest electricity outages worldwide. The System
Average Interruption Duration Index (SAIDI) was 0.74
minute per customer per year, while the System Average
Interruption Frequency Index (SAIFI) was 0.02
interruptions per customer per year. This means the
average electricity customer would only experience one
interruption every 50 years.
