(National Institute of Standards and Technology) Automated systems for network protection, outage management, and restoration enable electric utilities to maintain service continuity through network reconfiguration. We evaluate the impact of interoperability investments on distribution system resilience during Hurricane Irma through a reduced form analysis of sustained customer outages. The expected number of interruption hours during that hurricane was relatively lower for regions of the Florida distribution grid that invested more in interoperability enhancements, all else being equal. We use advanced metering infrastructure penetration as a proxy and leading indica tor of investment in interoperability enhancements. Employing only publicly available data resources, we conservatively estimate that Florida counties that made these investments realized nearly $1.7 billion of operational resilience benefits in the form of avoided customer interruption costs during Hurricane Irma
