The NGCP previously raised yellow and red alerts on the Luzon grid because of low electricity reserves.

According to the Department of Energy (DOE), a yellow alert  is usually raised is when “a grid’s reserve power—the difference between supply and demand—is below the required level.” However, it does not necessarily lead to power outages.

Meanwhile, the NGCP raises a red alert on grids when there are zero operating reserves, which could lead to consumers to experience rotational brownouts.  /muf
