Weatherizing Infrastructure in the North and Terrorism Emergency Readiness Act of 2025

What this does

This bill orders the Secretary of Homeland Security to develop and run a single preparedness exercise. The exercise must model a terrorist attack on critical infrastructure occurring during an extreme cold weather event, such as a polar vortex, and test the cascading effects on critical services. The scenario must cover how emergency managers, state officials, and private-sector and community stakeholders could mitigate the attack and bolster community resilience, and it must involve coordination with federal, state, local, Tribal, and territorial agencies. Within 60 days of finishing the exercise, the Secretary must send an after-action report to the House Homeland Security Committee and the Senate Homeland Security and Governmental Affairs Committee, laying out initial findings, plans for applying lessons learned, and any proposed legislative changes. The bill creates no new spending and no authority beyond running this exercise and reporting on it.
