The loss of power at a hospital, can be catastrophic, according to an article on  the Microgrid Knowledge website.

Hospitals need electricity for day-to-day needs as well as critical functions such as ventilators and dialysis machines.

Hospitals can also be a shelter for the surrounding community during emergencies. Because of this hospitals need some form of backup power. A microgrid can combine  a variety of energy sources while managing energy supply and demand. During an emergency, a microgrid can continue to supply the hospital with power when the surrounding grid goes down. 

Plus, microgrid prices are becoming more competitive, and the COVID-19 pandemic has forced hospitals to be flexible in where they route and treat patients. And while hospitals generally have back-up generators for their critical branches, a power outage could cause the rest of the building to go dark, according to a Utility Dive article.
