How PowerTRX Reliability Works
Power TRX Reliability prides itself on ease of use and its simplified core features. If you have internet access and a web browser, you can access the service. Users enter outages through a web application via a browser and can easily check their data at any time.
Core functions include:
- Recording outage information
- Importing and updating large sets of outage data via CSV
- In-system reporting on IEEE statistics and monthly reliability performance
- Identifying problem areas and common outage causes
Subscribers receive an annual benchmarking report that analyzes aggregate data and compares utilities by customer count, geographic region, and outage types.
Users can also securely sync their outage management system (OMS) data directly from one system to the next through an application programming interface (API). Please contact PowerTRX@PublicPower.org for more information on the API integration.
Certificate of Excellence in Reliability
As a subscriber, your utility can qualify for an annual Certificate of Excellence in Reliability. Recipients are determined by comparing their reliability data with the national reliability data published by the Energy Information Administration. To receive a certificate, the utility must be in the first quartile of utilities for System Average Interruption Duration Index (SAIDI) based on the last five years of EIA data.
In 2025, we recognized 256 public power utilities for their excellent 2024 reliability records.
