Digital Twins for Resilient and Secure Utility Systems

The US electric grid is entering an era of new operational risks, driven by unprecedented load growth, stringent reliability standards, and the proliferation of connected devices across the transmission and distribution grid. Distribution utilities are facing unpredictable demand from hyperscale data centers, electrified transportation fleets, energy‐intensive manufacturing facilities, and upgrades to Department of Defense facilities. The cost of an unreliable grid is increasing rapidly, with the Department of Energy (DOE) estimating that power interruptions cost the US economy $150 billion annually. 1
