Key Performance Indicators
Key Performance Indicator for Reliability of Power Supply
The System Average Interruption Duration Index (SAIDI) and the System Average Interruption Frequency Index (SAIFI) provide data from the perspective of an average customer over a calendar year and focus, respectively, on total outage duration and frequency.
Measuring SAIDI and SAIFI data is identified as a good practice by the Institute of Electrical and Electronics Engineers (IEEE) and allow utilities to compare their network reliability internationally (over two-thirds of economies worldwide use these metrics)
Energy Fiji Limited is committed to improving the reliability of power supply and preventing power interruptions through a continuous monitoring of its SAIDI and SAIFI indices, in line with best international practices.
The table below shows the controllable SAIDI and SAIFI figures recorded for the period 2012 to 2019.
