Frozen Out in Texas: Blackouts and Inequity
JP Carvallo, Payne Institute Earth Observation Group Researcher Feng Chi Hsu, Zeal Shah, and Jay Taneja write about how in February, blackouts in the Texas power grid left over 4.5 million customers in the dark, many of them for several days. A substantial amount of these blackouts were transmission disconnections and emergency load shedding events triggered by ERCOT, the entity in charge of ensuring a reliable supply of electricity in Texas. In this analysis, we use satellite data on nighttime lights to track blackouts at the census block group (CBG) level and correlate it with demographic data to understand how equitable these blackouts were.
