In November 2023, NERC’s Electricity Information Sharing and Analysis Center (E-ISAC) conducted the seventh biennial GridEx. The following exercises make up GridEx: • Distributed Play: On November 14 and 15, 2023, operational participants across North America exercised the resilience of the electric system in the decentralized and independent Distributed Play exercise. The EISAC’s GridEx Planning Team developed core planning and exercise materials, which local planners across the continent used to design and conduct their own exercises for their organizations. • Executive Tabletop (Tabletop): On November 16, 2023, industry executives and government leaders from the United States and Canada convened in person in Washington, D.C., as well as virtually, to explore the challenges presented by cyber and physical attacks against the electric grid and the electric market system. This report summarizes the recommendations and observations identified through each exercise. The recommendations are intended to help electric utilities, government partners, the E-ISAC, and other stakeholders prepare for and respond to security incidents that affect the North American electricity system.
