“…In the US, half of power outages are due to natural causes. In particular, electric lines located in wooded areas are particularly vulnerable in case of strong winds and thunderstorms (Rentschler, Obolensky, & Kornejew, 2019). On the contrary in Bangladesh, only a fraction of the daily outages can be explained by natural disasters in period of monsoon and pre-monsoon ; the vast majority of the electricity outages are due to poor-quality infrastructure.…”

“…Natural hazards are a leading driver of power outages around the world (Panteli and Mancarella, 2015;Mukherjee et al, 2018). Generally, they are responsible for power interruptions that last significantly longer, ranging from hours to days, than those due to non-natural hazards (Rentschler et al, 2019b). Among other effects, long-term power interruptions impede the regular performance of household tasks, bring the activity of businesses, industries, and agricultures to a halt, and cause the disruption of other CIs (see Sect.…”

Abstract. Flood damage assessment is a critical aspect in any decision-making process on flood risk management. For this reason, reliable tools for flood damage estimation are required for all the categories of exposed elements. Despite infrastructures can suffer high economic losses in case of flood, compared to other exposed sectors, their flood damage modelling is still a challenging task. This is due, on the one hand, to the structural and dynamic complexity of infrastructure networks, and, on the other hand, to the lack of knowledge and data to investigate damage mechanisms and to calibrate and validate damage models. Grounding on the investigation of the state-of-the-art, this paper presents a conceptualization of flood damage to power grids and reviews the methodologies in the field for an in-depth understanding of the existing modelling approaches, challenges, and limitations. The conceptual model highlights: (i) the different kinds of damage (i.e., direct, indirect, and systemic) the network can suffer, (ii) the hazard, exposure, and vulnerability parameters on which they depend, (iii) the spatial and temporal scales required for their assessment, (iv) the interconnections among power grids and economic activities, and (v) the different recipients of economic losses. The development of the model stresses the importance of dividing the damage assessment into two steps: the estimation of damage in physical units and the consequent economic losses in monetary terms. The variety of damage mechanisms and cascading effects shaping the final damage figure arises, asking for an interdisciplinary and multi-scale evaluation approach. The ultimate objective of the conceptual model is to be an operative tool in support of more comprehensive and reliable flood damage assessments to power grids.

“…Natural shocks play a significant role in such infrastructure disruption. Reviewing thousands of power outages from 28 countries in the European Union and North America, Rentschler et al (2019b) suggest that 20-80 percent of all power outages are caused by natural shocks. Data constraints mean that such estimates do not usually exist in developing countries, making it difficult to estimate the productivity losses associated with natural shocks.…”
