“…Meyer et al 2013). Some examples of ways to incorporate climate change considerations in planning can be found, including a 2016 study of vulnerabilities of power system infrastructure to flooding (Chattopadhyay et al 2016) and others focused on different types of critical infrastructure (Schweikert, Espinet, and Chinowsky 2018). This is an important consideration for future work and discussed in the recommendations at the end of this work.…”

“…Coal fired generation facilities are most vulnerable to droughts, heatwaves, and supply chain considerations (see Table 7). Flooding was identified as an important criteria for resilient facility design and a 2016 study in Bangladesh particularly noted that the historical guidelines for flood design are likely to be inappropriate for future conditions (Chattopadhyay et al 2016).…”

“…In the United States, between 2000-2016, 35% of all outages related to a fuel supply emergency were for coal generation facilities, the largest of any fuel type (see Table 2). In a study in Bangladesh, additional vulnerabilities identified in the supply chain included the mining, Low water levels to be used for cooling and high temperatures (25°C) that regulations prevent from being discharged (Harto and Yan 2011) transportation and storage of coal vulnerable to natural hazard events including flooding (Chattopadhyay et al 2016).…”

“…In most case studies, permitting regulations resulted in curtailment or closure of facilities when intake water exceeded the permitted temperatures (approximately 75 degrees Fahrenheit in most studies) (McCall, Macknick, and Macknick 2016). In a study that includes climate change considerations, thermal electric power stations (including coal) were identified to have increasing vulnerability in the future specifically due to increased ambient temperatures and water availability that will affect water required for cooling (Chattopadhyay et al 2016).…”

Executive SummaryResilience against infrastructure failure is essential for ensuring the health and safety of communities during and following natural hazard situations. The Swiss Reinsurance Company Ltd (Swiss Re) estimated 2017 global infrastructure losses at 337 billion USD, with all but 7 billion resulting from natural hazards. (Of this, more than half was uninsured.) These losses are expected to grow as climate change continues unless actions are taken to prevent them. Importantly, people and communities in developing and emerging economies are expected to be disproportionately affected.An understanding of how natural hazards impact society in terms of economic cost, recovery time, and damages to critical infrastructure is essential for developing robust approaches to increasing resilience. Identifying specific vulnerabilities allows for better communication, planning, and situation-specific interventions. This is particularly relevant in areas recovering from a natural hazard that have the opportunity to build back their infrastructure, and for those currently planning infrastructure expansions. This paper 1 , commissioned by the World Bank's Global Facility for Disaster Reduction and Recovery, looks at a range of historical natural hazard events and their impact on power system infrastructure including: generation facilities, transmission and distribution assets, and fuel supply chains. We consider recent hurricanes, earthquakes, droughts, heat waves, extreme wind and rainfall events, ice and thunder storms as well as wildfires. For many of these, data are available for the same type of hazard in different geographies which provides information not only on specific vulnerabilities, but whether the impacts are location dependent. Where available, specific design considerations, cost information for repairs, and the recommendations for 'building back better' are presented.Within the three categories in the power system, we identify specific areas that require attention:

Vulnerability and resilience of power systems infrastructure to natural hazards and climate change

The value of critical infrastructure rests in the services they provide. Electricity in particular underpins the operation of hospitals, schools, financial systems, transportation assets, telecommunications, and water treatment, and affects many other aspects of daily life. There is an emerging recognition of power systems as complex adaptive systems and a proliferation of work on how to make them more resilient in the face of natural hazards and climate change. However, the term “resilience” is often used to encompass important, but distinct, aspects of infrastructure analysis including vulnerability, asset hardening, resistance to failure and risk management. As work in this domain has evolved through disciplines from risk management, economics, engineering and policy, the term “resilience” has often remained vague or referred to broad aspects of infrastructure performance under hazard events. Here we argue it is important to distinguish asset hardening and risk management from aspects of a system that allow it to deliver services even when some of its components fail. Understanding infrastructure vulnerability and risk are key components of resilient power system assessments. However, differentiating vulnerability from functional resilience (service delivery even when components fail) can help identify gaps in data, modeling and decision making. We propose that continued progress in this area can be made by unifying these areas of work through (1) understanding vulnerability and risk management in the context of hazards and climate change and (2) an orientation of resilient service delivery as a unifying concept for resilience analysis. This article is categorized under: Vulnerability and Adaptation to Climate Change > Learning from Cases and Analogies

A constant production and delivery of electricity is crucial to the functioning of the society. Power systems, however, suffer from either physical, institutional or community level challenges under climate change. Specifically, Malawi is exposed to both climatic and geologic hazards. One of the guiding principles of the needs assessment and recovery strategy is to move from response to long term resilience. The national energy policy (NEP) is considered as one of the drivers of long-term power system resilience (PSR). Understanding the status of NEP is critical in coming up with long term resilience solutions because the qualitative evaluation in this case considers information about risks, the perceived severity of risks and possible impacts of shocks. Although prior studies contributed significantly to the resilience of electricity systems, none of those studies explored the possibility of the NEP being a critical key in promoting the resilience of the electricity sector to extreme weather events. This novel study, therefore, assessed the capacity of the NEP to promote infrastructure and institutional PSR. It also identified challenges regarding the capability of the policy to support PSR. Finally, the study suggested key policy solutions to the identified challenges. Content and thematic analysis were used to analyse the status of energy policy. While the capacity of the policy to promote infrastructural resilience was assessed by evaluating the level of technical policy implementations and status of electricity supply, institutional resilience’s capacity was determined through legal and capacity building policy implementations. Notably, the NEP fails to support PSR. Resilience policies, energy policy financing, energy policy management, coordination with key stakeholders, politics, energy data and capacity of the Ministry of energy are critical issues.
