OUR CITY G4-EU28 G4-EU29 Reliability Toronto Hydro evaluates service reliability through two main measures: duration and frequency of outages. System Average Interruption Duration Index (SAIDI) is a measure of the annual average duration of outages for customers (in hours). System Average Interruption Frequency Index (SAIFI) is a measure of the frequency of interruptions. In 2016 relative to 2015, Toronto Hydro saw a reduction in the average duration and frequency of outages. In fact, since 2010, the average number of service interruptions has improved by 21% and the average duration of interruptions is down by 26%. Toronto Hydro’s average duration was more than five times lower than the national average (as reported by CEA) while Toronto Hydro’s frequency of interruptions is less than half the national average (as reported by CEA). 5.17 1.29 2010 1.43 2011 1.03 2012 1.14 2.15 24 TORONTO HYDRO I 2016 CORPORATE RESPONSIBILITY REPORT 2013 1.00 1.06 2014 2015 0.95 2016 6.16 Actual CEA Average 4.66 9.49 6.38 5.08 5.66 SAIDI Actual CEA Average 1.77 2010 1.62 2011 1.40 2012 1.44 2013 1.39 1.45 2014 2015 1.40 2016 2.63 2.54 2.72 2.39 2.32 3.10 SAIFI
