The Power of an Outage: Cascading Impacts of Extended Power Disruptions

Electricity powers every community lifeline. Our modern world depends on electricity to sustain communications, water systems, healthcare, transportation, and public safety operations. When outages are prolonged or widespread, these systems become increasingly strained, creating complex coordination and continuity challenges for emergency managers and response partners.
Using real world case studies, this session examines how extended outages affect lifeline continuity and expose operational interdependencies that are often not fully understood until systems begin to fail. Participants will engage through facilitated discussion and real time polling to examine how these challenges may affect their own organizations and communities.
As extreme heat, severe weather, and increasing demand place greater strain on electric systems, the risk of prolonged and widespread power outages continues to grow, underscoring the critical need for coordinated preparedness across sectors. The session will also highlight how two electric utilities in Arizona are working collaboratively to identify shared vulnerabilities and strengthen coordination to improve preparedness and continuity.
Participants will gain practical insight into how lifeline dependencies affect their own systems, identify where coordination gaps may exist, and receive a ready-to-use tabletop exercise toolkit to support continued planning within their own organizations.
