Abstract

ABSTRACT This is the second of two papers that study the economics of long-duration, widespread electric power interruptions (LDWIs) caused by extreme weather events in the U.S.A., and how utilities and regulators are evaluating measures to reduce the vulnerability of electricity infrastructure to such disruptions. In this paper, we review case studies of five jurisdictions in different U.S. states that experienced LDWIs over the past two decades, examining how these events have influenced utilities’ and regulators’ approaches to strengthening electricity infrastructure against potential future interruptions. We find that (i) most of the utilities do not estimate economic benefits of large-scale storm-hardening and other measures in terms of either avoided customer costs or regional economic impacts; (ii) the concept of ‘resilience’ plays little practical role in this type of decision-making; and (iii) institutional factors have a major influence on whether and how the economic benefits of storm-hardening and related measures are evaluated.

降低长期、大范围电力中断风险的电力公司投资估值，第二部分：案例研究

这是两篇论文中的第二篇，研究了美国极端天气事件造成的长时间、大范围电力中断(ldwi)的经济性，以及公用事业和监管机构如何评估减少电力基础设施对此类中断的脆弱性的措施。在本文中，我们回顾了在过去二十年中经历过ldwi的美国不同州的五个司法管辖区的案例研究，研究了这些事件如何影响公用事业公司和监管机构加强电力基础设施以应对未来潜在中断的方法。我们发现(i)大多数公用事业公司没有从避免客户成本或区域经济影响的角度估计大规模风暴强化和其他措施的经济效益;(ii)“弹性”概念在这类决策中几乎没有实际作用;(三)制度因素对是否以及如何评估风暴强化及相关措施的经济效益有重大影响。

期刊介绍： Sustainable and Resilient Infrastructure is an interdisciplinary journal that focuses on the sustainable development of resilient communities. Sustainability is defined in relation to the ability of infrastructure to address the needs of the present without sacrificing the ability of future generations to meet their needs. Resilience is considered in relation to both natural hazards (like earthquakes, tsunami, hurricanes, cyclones, tornado, flooding and drought) and anthropogenic hazards (like human errors and malevolent attacks.) Resilience is taken to depend both on the performance of the built and modified natural environment and on the contextual characteristics of social, economic and political institutions. Sustainability and resilience are considered both for physical and non-physical infrastructure.
