This bill directs the Department of Homeland Security to develop and conduct a collective response to a terrorism exercise that includes the management of cascading effects on critical infrastructure. The scenario centers on an extreme cold weather event, such as a polar vortex, and requires coordination across federal, state, local, tribal, territorial, and private sector stakeholders.
After the exercise, DHS must submit an after-action report to Congress within 60 days containing initial findings, plans for incorporating lessons into DHS operations, and any proposed legislative changes, while protecting classified information as needed. The act is designed to bolster domestic preparedness by testing cross-government and private-sector resilience to simultaneous threats and extreme weather.
At a Glance
What It Does
The Secretary of Homeland Security must develop and conduct a collective response exercise that includes the management of cascading effects on critical infrastructure during an extreme cold scenario, with a scenario specified in subsection (b).
Who It Affects
Federal DHS components, state and local emergency management agencies, tribal and territorial partners, private sector owners/operators of critical infrastructure, and community stakeholders.
Why It Matters
This exercise tests cross-jurisdictional coordination and resilience to simultaneous terrorist and weather-driven disruptions, yielding practical lessons and potential policy recommendations for strengthening critical infrastructure security and response.

What This Bill Actually Does
The Weatherizing Infrastructure in the North and Terrorism Emergency Readiness Act of 2025 requires the Department of Homeland Security to design and run a collective response exercise. The exercise asks DHS to simulate how cascading failures in essential services could unfold when a terrorist incident intersects with an extreme cold weather event.
The scenario is constructed to test how emergency managers, state and local officials, tribal and territorial partners, and private sector and community stakeholders would coordinate to keep critical services running and to mitigate cascading impacts on infrastructure such as power, water, communications, and transportation networks. The exercise explicitly covers coordination across federal agencies and with private-sector partners whose systems underpin critical infrastructure.
The Five Things You Need to Know
The exercise requires coordination across federal, state, local, tribal, and private-sector partners.
The scenario focuses on an extreme cold event with cascading effects on critical infrastructure.
The exercise tests mitigation strategies and resilience-building across multiple jurisdictions and sectors.
An after-action report is due within 60 days after exercise completion, outlining findings and implementation plans.
The report may inform proposed legislative changes to DHS operations and infrastructure resilience policies.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Section 1 designates the act by its official name: Weatherizing Infrastructure in the North and Terrorism Emergency Readiness Act of 2025.
Exercise on terrorism during extreme cold
Section 2 directs the Secretary of Homeland Security, through appropriate offices and components, to develop and conduct a collective response to terrorism exercise. The exercise must address cascading effects on critical infrastructure as defined in 42 U.S.C. 5195c(e) and be set within a scenario involving an extreme cold weather event (e.g., a polar vortex). It requires participation and coordination among emergency managers, state and local officials, appropriate private sector and community stakeholders, and coordination with federal agencies.
Reporting
Section 3 requires that not later than 60 days after the completion of the exercise, the Secretary shall submit an after-action report to the House Committee on Homeland Security and the Senate Committee on Homeland Security and Governmental Affairs. The report must present initial findings, outline longer-term plans to incorporate lessons learned into DHS operations, and propose legislative changes informed by the exercise, while protecting classified information as necessary.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- DHS and its component offices gain enhanced exercise experience and a framework for integrating lessons into ongoing operations.
- State, local, tribal, and territorial emergency management agencies benefit from better-coordinated planning and access to cross-jurisdictional resilience practices.
- Critical infrastructure owners and operators (e.g., electric, gas, water utilities, telecommunications) receive tested response protocols and resilience recommendations.
- Private sector partners and community stakeholders participate in decision-making processes that improve real-world incident response and continuity planning.
- Congressional committees receive a comprehensive after-action report with actionable recommendations and policy implications.
Who Bears the Cost
- DHS resources and staff time dedicated to designing, coordinating, and executing the exercise.
- State, local, tribal, and territorial agencies that must participate and align with the exercise’s scenarios.
- Critical infrastructure owners/operators that contribute data, participate in drills, and implement recommended improvements.
- Private sector partners may incur coordination burdens and potential costs to adapt systems or data-sharing practices to exercise needs.
- The government and participating entities may experience opportunity costs as resources are allocated to the exercise rather than other homeland security activities.
Key Issues
The Core Tension
The central tension is between creating a sufficiently realistic, cross-jurisdictional exercise to drive meaningful improvements and the administrative and financial burden placed on federal, state, tribal, territorial, and private-sector participants. Balancing robust scenarios with feasible participation and ensuring that lessons translate into durable changes without duplicating efforts or creating unfunded mandates is the key policy trade-off.
The bill creates a structured, large-scale exercise that involves multiple actors, which can be demanding for participants and resources. While it promises more realistic readiness, the approach raises questions about funding, data-sharing, and how lessons learned will be operationalized within existing DHS authorities.
There is no explicit funding mechanism, so implementation would depend on agency budgeting and potential subsequent legislation to authorize costs beyond current baselines.
