In this study, there are several ways to address energy reliability concerns during an extended power outage. This can include hardening the energy infrastructure to reduce potential loss of power, adding redundant backup systems with larger fuel tanks, and improving generator reliability through better maintenance. While each is valid, they are often expensive to adequately implement. The traditional emergency power approach for decades has been the use of building-tied emergency generators to start up and supply emergency power until the utility can come back on line. Unfortunately, operational experience from many recent extended power outages has shown that emergency backup generators are often mismatched in size with the building energy load, under-maintained such that their operational reliability is well below expected values, and have insufficient fuel to operate for the entire power outage. Here we describe how energy reliability and security can be enhanced with the use of Advanced Microgrids.
