APPA Recognizes Member Utilities For High Levels Of Reliability

The American Public Power Association (APPA) has honored 199 public power utilities with a "Certificate of Excellence in Reliability" for reliable performance in 2021.

Utilities that are subscribers to APPA’s eReliability Tracker service are eligible to earn these certificates. To earn a certificate, a utility’s 2021 System Average Interruption Duration Index (SAIDI) must fall in the top quartile of all utilities’ SAIDI numbers averaged from the past five years based on Energy Information Administration 861 survey data.

The certificates celebrate utilities that have provided exceptionally reliable service and power to their communities.

“It’s encouraging to see—once again—that public power’s track record for providing highly reliable service is backed up by the data,” said APPA Vice President of Operations and Technical Services Alex Hofmann. “These communities should be proud of their local power providers and appreciate the hard work that goes into earning this recognition.”

When looking at eReliability Tracker subscribers’ 2021 outage data, 93% of utilities that verified their 2021 outage data had a 2021 SAIDI that was below the average national SAIDI for 2016-2020 (according to EIA data). This data also includes investor-owned utilities and cooperatives.

This demonstrates that most public power utilities are above average in reliability when compared to all U.S. providers.
