1.4
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 245 public power utilities with
a "Certificate of Excellence in Reliability" for reliable performance. These utilities have
significantly outperformed the electric industry nationwide averages as gathered by the Energy
Information Administration. APPA collected data from public power utilities that subscribe to
APPA's eReliability Tracker software to track their reliability data. Of those utilities, 324 were
considered to have sound data that was included in the 2023 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 2023, ERMU's SAIDI was only 14.08 minutes (excluding major events), compared to the
industry average of 148 minutes (excluding major events). In simple terms, that means that
averaged out over our 13,543 electric customers in 2023, each customer could expect to have a
total outage time of about 14 minutes; that is 134 minutes shorter than the national average
for outages.
I would like to recognize the Elk River Municipal Utilities team for their continuous devotion to
provide reliable electric service to all our customers throughout 2023. This national recognition
is confirmation of the outstanding reliable service we provide each and every day.
