Research Brief: Critical Infrastructure in Texas

---

Overview

Texas operates one of the largest and most complex critical infrastructure ecosystems in the United States. Its energy assets, transportation corridors, water systems, communications networks, and emergency services form the backbone of not only the state’s economy but also national supply chains and public safety systems. As population growth, climate volatility, and technological integration accelerate, understanding the risks facing Texas’s critical infrastructure — and the strategies required to strengthen resilience — has become increasingly urgent.

This research brief provides a high-level assessment of critical infrastructure in Texas, focusing on key sectors, emerging threats, and strategic considerations for resilience planning.

Critical Infrastructure Landscape

Texas’s infrastructure spans multiple interdependent sectors:

• Energy Sector: Texas leads the nation in energy production, including oil, natural gas, wind, and solar. The electric grid supports residential demand, industrial operations, and national energy distribution.

• Transportation & Logistics: Highways, rail networks, ports, and airports enable domestic and international trade. The Houston Ship Channel is among the most economically significant ports in the country.

• Water & Wastewater Systems: Municipal and regional water systems support growing urban populations, agricultural operations, and industrial activity.

• Communications & Information Technology: Broadband networks, data centers, and emergency communications enable commerce, governance, and crisis response.

• Emergency Services & Public Health: Hospitals, first responders, and emergency management agencies play a critical role during disasters and infrastructure disruptions.

These sectors are highly interconnected, meaning disruption in one area can cascade into multiple systems.

Threat Environment

Texas’s critical infrastructure faces a wide range of threats that span physical, cyber, and environmental domains.

Natural hazards such as hurricanes, flooding, drought, and extreme temperatures regularly test infrastructure capacity. Severe weather events can disrupt power generation, damage transportation networks, and strain water systems.

Cyber threats continue to increase as infrastructure operators rely more heavily on digital control systems. Ransomware attacks, supply chain compromises, and insider threats present growing risks, particularly for utilities with limited cybersecurity resources.

Aging infrastructure and deferred maintenance further increase vulnerability. Many systems were not designed to handle current population levels or climate conditions.

Finally, interdependency risks amplify impacts. Power outages can disrupt water treatment, communications, healthcare delivery, and emergency response operations simultaneously.

Key Observations (Illustrative Findings)

• Energy systems remain highly efficient but vulnerable to extreme weather and operational disruptions.

• Transportation infrastructure faces congestion and limited redundancy in high-growth regions.

• Water utilities show uneven cybersecurity preparedness, particularly among smaller operators.

• Communications systems rely on centralized assets that may lack sufficient backup capabilities.

• Emergency services experience staffing and capacity challenges during prolonged incidents.

These findings highlight the need for coordinated, cross-sector resilience planning rather than isolated mitigation efforts.

Resilience Efforts and Gaps

Texas has made progress in resilience planning through public-private partnerships, infrastructure modernization initiatives, and emergency preparedness exercises. However, gaps remain in consistent data sharing, cybersecurity maturity, funding stability, and workforce development. Smaller and rural infrastructure operators often face the greatest challenges due to limited resources.

Conclusion

Critical infrastructure in Texas is essential to economic stability, public safety, and national security, yet it operates within a rapidly evolving risk environment. Strengthening resilience will require coordinated governance, sustained investment, and integrated risk management across sectors. By prioritizing collaboration, modernization, and workforce capacity, Texas can better protect its infrastructure systems and ensure continuity of essential services in the face of future disruptions.
