Investments in grid produce nation’s top reliability

In a benchmark study of ComEd, compared to similar utilities, the utility was ranked number one in terms of how low the frequency and duration of outages were for customers. Recent metrics that reflect the frequency of outages for ComEd customers have improved by more than 50% compared to 2012 and earlier. Additionally, metrics that reflect the duration of outages have improved by approximately 20% over the same timeframe, meaning customers experience shorter interruptions when service is disrupted.

“Our customers count on ComEd to deliver world-class reliability to meet their growing electrification needs,” said ComEd President and CEO Gil Quiniones. “Our performance on reliability and resilience is the result of targeted investments, tailored to address the growing challenges the grid faces from extreme weather, increasing load demands and cybersecurity. We will continue to take the steps necessary for the 4.2 million customers we are privileged to serve.”

ComEd customers have seen continuous improvement in grid reliability performance in recent years. Since ComEd started smart grid improvements in 2012, it has improved overall reliability by more than 57 percent, helping customers avoid nearly 24.7 million customer interruptions and save more than $4.3 billion in outage-related costs.

The panel of peer companies in the study consists of publicly held utilities that primarily serve one million or more customers and have transmission and distribution operations. The primary sources of data come from multi-utility panel surveys conducted by reputable companies, regulatory reports and the U.S. Energy Information Administration.
