Examining Vulnerabilities of America's Power Supply

The electricity infrastructure of the United States consists of power plants generating electricity, transmission and distribution lines, and transformers and substations, which all work together to bring power to American homes and businesses. The stability, reliability, and security of the electric grid are important components to prevent extensive power outages that could interfere with the everyday lives of millions of Americans. However, the electric grid is vulnerable to a wide range of threats that could cut off power to families and businesses, including physical, cyber, EMP, and space weather threats. Our nation's power supply cannot be protected overnight, particularly as utilities struggle to adapt technology to manage a growing number of cybersecurity threats. Cyber threats to the power grid will continue to evolve, particularly as more interconnected smart technologies are incorporated into the electric grid. As protective technology improves, so does the capability and creativity of those conducting attacks.
