In 2017, Hurricane Maria proved how fragile Puerto Rico’s grid is to natural disasters. The consequence of this fragility was the longest power blackout in the history of the U.S., which affected 3.3 million people, lasted for 3.4 billion customer-hours, and resulted in economic losses estimated in 95 billion USD. The solution, then, is energy resilience, defined here as the overall ability of an electricity system to prevent, mitigate, and recover from wide-area, long-duration outages. Accordingly, the aim of this study is to quantify the value of the energy resilience that solar microgrids can provide to electricity users in Puerto Rico.
