High-resolution electric service interruptions map and CBG-level share of population interrupted in Texas during the February 2021 winter storm.

The data package includes two files: a TIFF file and a CSV file. The TIFF file (raster) represents a binary power interruptions map of the Texas region during the February 2021 winter storm. This map has a spatial resolution of 15 arc-seconds and was generated by detecting power interruptions in a composite nighttime lights image of the Texas region from February 14-18, 2021. Each pixel in the map corresponds to a geographical location and indicates whether an interruption was detected in that location or not. A pixel with a value of 1 represents an interruption, while a pixel with a value of 0 represents no interruption. In most cases, the missing pixels indicate the absence of population, but in some cases, they indicate data unavailability. The dataset also includes a CSV file that provides the estimated share of population in outage in each Census block group (CBG) of the Texas region. This file was created by aggregating pixel-level outage values from the TIFF file to the CBG level. Together, the TIFF and CSV files in the dataset provide a detailed view of the electric service interruptions that were observed across the Texas region during the severe winter storm of February 2021.
