APPA created the Distribution System Reliability and Operations Survey with the intention of evaluating how public power systems provide service to their end-use customers. The survey intends to assist members in their individual efforts to understand and analyze the issues that arise from maintaining and operating an electric distribution system, ranging from outrage tracking to construction design. 

This is a survey distributed every two years and will next be released in 2017. The most recent survey was distributed in 2015, and an analysis of responses received can be found below. We thank those who participated in this year’s survey. The more participants, the more practical and robust our analysis will be.
