We benchmark our safety performance against the performance of other companies who are members of the Canadian Electricity Association and in 2007, exceeded our ‘best in class’ targets.
Our 2007 lost time injury severity rate, which is a measure of the number of days workers were away from the job due to injuries, was 3.46, a number representing 36 days across the corporation, which is significantly lower than the 196 days recorded in 2006.
In 2007, our lost time injury frequency rate, which is a measure of the rate at which lost time injuries are occurring, was 0.29, representing a total of three injuries, compared with nine lost time injuries in 2006.
Reliability - Sustaining Power Service
In 2007, ENMAX Power Corporation delivered record-setting volumes of electricity to more customers than at any time in our company's history, while continuing to achieve top quartile performance for reliability.
The two key measurements used by the Canadian Electricity Association (CEA) to measure the reliability of a utility are SAIFE, which stands for system average interruption frequency index and SAIDI, which means system average duration frequency index. The first measures the number of interruptions to power service and the second calculates the length of each interruption.
For the second consecutive year, ENMAX Power's system reliability earned a top performer ranking among urban utilities reporting to the CEA.
Our strong record of investment in advanced distribution automation technologies over the past five years has steadily enhanced our overall electricity system performance. Through the installation of automated switches at key feeders, we have prevented sustained power interruptions to more than 90,000 customers and reduced potential customer interruption minutes by 6.4 million.
