Compact High Voltage Gas Insulated Substations (GIS) coupled with underground transmission can effectively and economically build energy bunkers as opposed to large traditional Air Insulated Substations (AIS) requiring fortress like protection (exterior & interior 8-20’ walls with interlocking gating, curved roadways, anti-drone capability, extensive high intensity lighting & camera systems, forward looking radar, mantraps, annual first responder training, and security guards). This panel will present resilient solutions: 1) hiding substations & switchyards underground or in a building, 2) digital solutions enabling predictive asset health & performance, 3) a program to significantly reduce the risk and rapidly repair/replace/harden transformers, and 4) new solar storm & EMP mitigation solutions providing simpler and lower cost approaches to hardening against these threats.
