Texas Annual Reliability Indices Show EPE is Among Top Utilities

March 23, 2012

Thanks to the efforts of El Paso Electric Transmission and Distribution employees, EPE’s was once again the most reliable utility in Texas during 2011.

 The System Average Interruption Duration Index (SAIDI) and the System Average Interruption Frequency Index (SAIFI) are reliability indices compiled by the Public Utility Commission of Texas (PUCT). The SAIDI measurement rates the duration of outages while the SAIFI measurement measures the frequency of outages. The PUCT tracks the SAIDI and SAIFI of all investor-owned electric utilities operating in Texas, a total of 10.  During 2011, EPE’s SAIDI and SAIFI ratings were the best in Texas.  

Hector Puente, senior vice president of Operations at EPE, attributes this accomplishment to EPE transmission and distribution employees’ dedication to maintaining the equipment, system reliability and getting our customers’ electric service restored as quickly as possible.

“Providing safe and reliable electrical service to our customers is our number one priority.  We ask our transmission and distribution employees who are responsible for the daily operation of the electrical system to respond to any outage by evaluating the outage as quickly as possible, isolate the issue, and then make the necessary repairs in order to get our customers back on line,” said Puente. “I think it should be noted that while we ask employees to think and respond quickly, more than anything else, we want them to accomplish their work in a safe manner. At the end of the workday, we want everyone to go home to their loved ones.”
