Commonwealth Edison, the largest electric utility in Illinois, won the top national honor at PA Consulting’s 23rd annual ReliabilityOne Awards, which recognize the most reliable electric utilities in North America.

Commonwealth Edison bumped perennial favorite Florida Power & Light from the top spot – posting the highest collective score across PA’s measurements in resiliency, reliability, storm response, technology and innovation, sustainability, and customer engagement.

To determine the annual rankings, PA uses publicly available data from the System Average Interruption Duration Index (SAIDI), which measures average outage duration per customer, and the System Average Interruption Frequency Index (SAIFI), which measures the average number of interruptions per customer.

“We are delighted to announce that Commonwealth Edison has been recognized as this year’s most reliable US utility. They had a marked turnaround, and leveraged cutting-edge technologies, innovative designs, and extremely disciplined operational excellence to provide an especially high level of service reliability to their customers in 2022,” said Derek HasBrouck, PA Consulting’s ReliabilityOne program director.Commonwealth Edison takes first place in PA Consulting’s ReliabilityOne awardsReliabilityOne winners saw an improvement in reliability performance over the prior year, with SAIDI performance improving by four minutes.
