Evaluation and Load Selection using Energy Storage System Priority Index (ESSPI)

This paper discusses important metrics that should be considered for determining critical loads and locations for energy storage. The evaluation process for these loads is to rank them as critical, essential, discretionary, luxury and disposable. This paper also describes the evaluation criteria for location selection of energy storage systems. The equation presented in this paper determines which loads should be considered to have a backup energy storage system, so in case of a blackout event, the critical and important loads/locations can recover faster. The decision and criteria are based on the experience of Puerto Rico after hurricane Maria. These criteria can be changed or adapted for different regions around the world for different loads that need energy storage systems.
