According to the Department of Energy, a yellow alert is raised when a grid’s reserve power — the difference between supply and demand — is below the required level. However, the alert will not lead to power outages.

Meanwhile, a red alert is raised on grids when there are zero operating reserves, which could lead to consumers to experience rotational brownouts.  (Editor: Mike U. Frialde)
