1.5
SUBJECT:
American Public Power Association Certificate of Excellence in Reliability
ACTION REQUESTED:
Receive the APPA Certificate of Excellence in Reliability
BACKGROUND/DISCUSSION:
The American Public Power Association (APPA) recently honored 221 public power utilities with
a "Certificate of Excellence in Reliability" for reliable service. These utilities have significantly
outperformed the electric industry nationwide averages as gathered by the Energy Information
Administration. APPA collected data from 524 public power utilities that track their reliability
data via the eReliability Tracker. Of those utilities, 285 were considered to have sound data that
was included in the 2022 Annual Benchmarking Report.
The tracker performs calculations for System Average Interruption Duration Index (SAIDI) which
measures the average outage time per customer on the system, System Average Interruption
Frequency Index (SAIFI) which measures how often a customer on our system could expect to
experience an outage, and Customer Average Interruption Duration Index (CAIDI) which
measures averaged outage duration of all customers that actually experienced an outage.
The report also includes calculations for Momentary Average Interruption Frequency Index
(MAIFI) and Average Service Availability Index (ASAI) which helps utilities to compare, collect,
categorize, and analyze their outage information.
For 2022, ERMU's SAIDI was only 13.29 minutes (excluding major events), compared to the
industry average of 140 minutes (excluding major events). In simple terms, that means that
averaged out over our 13,228 electric customers in 2022, each customer could expect to have a
total outage time of about 13 minutes; that is 127 minutes shorter than the national average
for outages.
I would like to recognize all Elk River Municipal Utilities employees for their continued
commitment to provide reliable electric service throughout 2022 to our customers. This
national recognition is a testament to the exceptional service and value we provide every day.
