A blackout is understood to be a sudden supra-regional power and infrastructure and supply failure that covers large parts of Europe and lasts for a longer period (> 12 hours). The decisive factor is that the other infrastructures are also affected and help from "outside" cannot be expected. Everything that has not been prepared and provided for on site will not be available. Moreover, the power outage is only the starting point for longer-term supply interruptions/bottlenecks.
