Supply Chain and Inflation Pressures

TVA continues to experience supply chain pressures resulting from inflation, tariffs and other trade restrictions, material constraints, and labor availability.  These factors have contributed to project delays, limited availability of critical materials, and increased costs for both materials and labor.  To help mitigate these risks, TVA actively manages its supply chain through strategic contracting, demand management strategies, and proactive supplier engagement and support.  While most tariff-related impacts have been minor to date, prolonged or project-specific tariffs could have more significant long-term effects.  TVA anticipates that inflationary and tariff pressures will persist into 2026.  Although these challenges have been managed with limited disruption to business operations thus far, continued or escalating pressures could result in more substantial operational impacts and increased pressure on power rates.

Safeguarding Assets    

Physical Security — Non-Nuclear Asset Protection.  TVA utilizes a variety of security technologies, security awareness activities, and security personnel to prevent sabotage, vandalism, and thefts.  Any of these activities could negatively impact the ability of TVA to generate, transmit, and deliver power to its customers.  TVA's Police and Emergency Management personnel are active participants with numerous professional and peer physical security organizations in both the electric industry and law enforcement communities. 

    TVA works with the North American Electric Reliability Corporation ("NERC"), the SERC Reliability Corporation, the North American Transmission Forum, and other utilities to implement industry approved recommendations and standards. 

    Nuclear Security.  Nuclear security is carried out in accordance with federal regulations as set forth by the NRC.  These regulations are designed for the protection of TVA's nuclear power plants, the public, and employees from the threat of radiological sabotage and other nuclear-related terrorist threats.  TVA has security forces to guard against such threats.

Cybersecurity.  TVA operates in a highly regulated environment with respect to cybersecurity.  TVA's cybersecurity program aligns or complies with the Federal Information Security Modernization Act, the NERC Critical Infrastructure Protection requirements, and the NRC requirements for cybersecurity, as well as industry best practices.  As part of the U.S. government, TVA coordinates with and works closely with the U.S. Department of Homeland Security's Cybersecurity and
