Abstract

We present the science-quality NASA Black Marble nighttime lights (NTL) as an alternative modern tool for electric grid assessment. On key locations extremely devastated by Super Typhoon Yolanda back in 2013, the scales of impact were visualized and progressive restoration of electricity were monitored. Detailed map showing the NTL reduction revealed localized variations of vulnerabilities in the grid, consequently requiring a more targeted response. Timeseries profile of NTL has shown contrasting recovery rates despite experiencing similar storm level exposure. Black Marble's consistency and high spatio-temporal resolution could potentially address barriers that impede fast and reliable electrification estimates, especially that sectors like healthcare are exposed to heightened morbidity and mortality during weather-induced prolonged power service interruptions.
