Summary/Abstract
This study examines the increased tropical cyclone-blackout-heatwave compound risk in Louisiana. Using projections of tropical cyclones, sea level rise, heatwaves, and power system resilience modeling, the study concludes that “the return period for a compound event comparable to Hurricane Ida (2021), with approximately 35 million customer hours of simultaneous power outage and heatwave exposure in Louisiana,” is expected to decrease by 17 times in this century. The return period in the historical climate of 1980-2005 is approximately 278 years, but the return period in the 2070-2100 climate under an SSP5-8.5 emissions scenario is only 16.2 years.
