In recent decades, the greenhouse effects are more and more visible and are leading to increase the frequency of extreme weather events, in particular heavy snowfalls, windstorms and heat waves, even in unexpected locations. Distribution and transmission system have been developed taking into account only single faults. Since extreme weather events cause multiple faults above wide regions, the usual reliability evaluation has to be combined with a grid resilience analysis. The risk assessment has to be carried out, taking into account the climate change scenarios for the next decades through the development of tools to estimate the probability of events and their impact on the infrastructures. Similar approaches can be used to increase response and recover capabilities optimizing the resources to be engaged in terms of crews and emergency hardware. Digitalization can help to combine accurate weather forecasting, by means of weather stations, sensors on the infrastructures, together with advanced models to evaluate the impact of different weather events on the distribution system.
