Enhancing Power System Resilience to Extreme Weather Events: A Qualitative Assessment of Winter Storm Uri

Published: Jan. 1, 2023

In February 2021, Winter Storm Uri left 11 million people in Texas without power, caused widespread water outages, and inflicted billions of dollars damage. While the severity this event was primarily by electricity generator failures, it made worse decisions utilities state regulators before, during, after event. This study seeks to (1) evaluate procedures electric during Uri, (2) provide a set recommendations improve resilience energy systems preparation for future extreme weather events. Fourteen semi-structured interviews were conducted with across underwent hybrid inductive-deductive qualitative coding. The analysis identified issues present operations decision-making processes as well potential solutions five dimensions resilience. outlines help ensure that are better prepared respond disaster events minimize community impacts, such sectionalizing circuits load shed, collaborating neighboring share resources, expanding use social media customer outreach.

Understanding the Disparate Impacts of the 2021 Texas Winter Storm and Power Outages Through Mobile Phone Location Data and Nighttime Light Images

Published: Jan. 1, 2023

Winter Storm Uri slammed Texas between February 13-17, 2021, and caused widespread power outages. Understanding the impacts of this catastrophic event on local communities has important meaning. In study, we examine winter storm its impact disparities different population groups over three stages disaster: initial-hit stage, power-outage recovery stage. The study focuses Harris County, which was severely affected by storm. We leverage home-dwelling time information from anonymized mobile phone location data to constrained mobility people due as a way quantify communities. Considering that may be outages, further integrate nighttime light (NTL) images into our analyses assess during use other two (i.e., stage stage). results reveal disparate in disaster. also find with socioeconomic demographic backgrounds, especially These help us better understand event, inform future response mitigation efforts identifying vulnerable communities, allocating resources, curtailing negative similar disasters.

Temporal public perceptions and experiences during water service disruptions: the case of Jackson, Mississippi

Environmental Research Infrastructure and Sustainability, Journal Year: 2024, Volume and Issue: 4(1), P. 015003 - 015003

Published: Jan. 5, 2024

Abstract Failures in urban water systems are becoming a common occurrence the US due to disasters, aging infrastructure, and financial constraints, among other concerns. For example, Jackson, Mississippi has experienced reoccurring outages, burdening community members as they must seek alternative sources. Prior research primarily focused on technical, institutional, public health aspects of crises, with limited attention perspectives. Understanding such social can shed light on, for priorities, levels trust, mental concerns, communication gaps. Here, we document temporal experiences perceptions during Jackson Water Crises. To do so, qualitatively analyzed news media data employed topic modeling techniques from two years, capturing service disruption events. Our results reveal cascading impacts outages end-users, including financial, social, technical issues. over time, indicate that trust government providers eroded, which may hinder support. show be useful tool utilities understand real-time. Recommendations proposed here inform future responses crises communities, ensuring end-users’ perspectives incorporated.
