Detrimental Effects of Poor Data Quality: Power Outage Data from 2002-2015
Authors: Shawn Adderly, Tim Sullivan, Mun Son, Todd Peterson
We examine the outage data from the Department of Energy from 2002-2015 to find trends in the duration, causes, and number of customers impacted. Due to erroneous data in some fields, a substantial percentage, (61% to 88%) of the data could not be used for the analysis. Much of the remaining data had to be corrected or reformatted before analysis could be performed.
