Utilities Enhance Security Measures Against Rising Threats to Power Grids
The Electricity Information Sharing and Analysis Center (E-ISAC) conducted a GridEx exercise from November 18-20, 2025, simulating coordinated attacks on power grids amidst a heat wave in the fictional nation of Beryllia. The U.S. and Canadian grids are experiencing increased physical threats, with over 3,500 security breaches reported in 2025. The exercise saw record participation, indicating heightened concern among utilities. New technologies, including AI and sensor fusion, are being tested to improve security against threats such as drones and vandalism.
