Microgrids move from disaster backup to mainstream energy infrastructure

After Hurricane Maria in Puerto Rico left much of the island without power for nearly a year, a solar and battery setup at Casa Pueblo kept its headquarters running and helped spark wider interest in microgrids.

OilPrice describes microgrids as self-contained power systems that generate, store, and manage electricity for a defined area, from a single building to an entire neighborhood.

The outlet says microgrids can operate connected to the main utility grid, drawing power when needed and selling excess, or they can fully disconnect and run independently through a process called islanding.

OilPrice also highlights the hardware requirements common to microgrids, including local generation, local storage, and a control system to manage both.

It points to growing use beyond disaster recovery, noting microgrids appearing on military bases and hospital campuses, and increasingly near AI data centers as power grids face added strain.
