  1. Climate-induced extreme weather events, as well as other natural and human-caused disasters, have the potential to increase the duration and frequency of large power outages. Resilience, in the form of supplying a small amount of power to homes and communities, can mitigate outage consequences by sustaining critical electricity-dependent services. Public decisions about investing in resilience depend, in part, on how much residential customers value those critical services. Here we develop a method to estimate residential willingness-to-pay for back-up electricity services in the event of a large 10-day blackout during very cold winter weather, and then survey a sample of 483 residential customers across northeast USA using that method. Respondents were willing to pay US$1.7–2.3/kWh to sustain private demands and US$19–29/day to support their communities. Previous experience with long-duration outages and the framing of the cause of the outage (natural or human-caused) did not affect willingness-to-pay.
  2. The transition to electric vehicles (EVs) is underway globally and EVs are expected to become more widely adopted in the coming years. One of the main characteristics of EVs is that they are not only seen as mean for transportation but also potentially as a flexible energy storage resource in vehicle-to-grid (V2G) applications. This paper proposes a resilience analysis on the feasibility of using EVs for power restoration and supply of residential networked microgrids (MGs) experiencing a power outage due to extreme weather. In order to evaluate the effectiveness of utilizing EVs as a backup power supply during an outage, various case studies are presented considering different scenarios and resilience metrics. Test results demonstrate that EVs can satisfy the energy requirements of a residential household for more than 6 hours but, also provide power to the distribution grid through MG aggregation.
