Gray Day 2025 is a hypothetical situation by which a large-scale energy outage happens throughout a large geographic space, leading to a lack of electrical energy and communications for an prolonged interval. This situation is used to check the preparedness and response plans of governments, companies, and people.
The significance of Gray Day 2025 lies in its means to determine vulnerabilities and gaps in present infrastructure and response mechanisms. By simulating a worst-case situation, stakeholders can consider their capabilities and make needed enhancements to reinforce their resilience to large-scale energy outages.
