Comparing distribution reliability among utilities is challenging. Many variables, including distribution system design, geographic location, vegetation exposure, and spending levels, can have large impacts on reliability statistics for individual companies. An accurate understanding of relative reliability is crucial to best allocate limited resources to improve reliability, navigate the path to acquire additional funding or provide data-driven evidence that a utility is taking the correct actions to provide top service to their customers.
First Quartile presents reliability results using the Canon Chart, a unique visual comparison of reliability performance. The Canon Chart allows companies to better understand the impacts of the above variables on three common reliability measures: SAIFI, SAIDI, and CAIDI.
