b'ReliabilityProviding safe and reliable electric service to customers is our core function. We continuously evaluate our bulk electric system to identify and implement system facility additions and upgrades necessary to meet WECC and the North American Electric Reliability Corporations reliability requirements. We work round the clock to ensure system reliability and minimize power outages across the transmission and distribution system. When outages do occur, it is our priority to safely restore power as promptly as possible. EPE provides tools to keep customers informed during outages with real time outage maps and an outage reporting application that provides updates on power restoration efforts. The System Average Interruption Duration Index (SAIDI) and the System Average Interruption Frequency Index (SAIFI) are reliability indices. The SAIDI and SAIFI metrics reflect the duration and frequency of outages, respectively. Overall, EPE has an outstanding system reliability record, having ranked first among Texas investor-owned electric utilities in both SAIDI and SAIFI for the last five years.2019 SYSTEM RELIABILITYEPE1 TX-IOU2SAIDI 57.93 140.11SAIFI 0.65 1.141 Includes Texas and New Mexico2 Texas Investor-Owned Utilities AveragePOWER RESTORATION EFFORT ASSISTANCEIn June, EPE deployed a total of 13 team members and other necessary equipment to assist with power restoration efforts in Dallas County, after over 350,000 customers were left without power because of major thunderstorms that swept through east Texas.9El Paso Electric Company Profile'
