The yellow alerts status is from 10:01 a.m. to 12 noon and 1:01 p.m. to 3 p.m., according to NGCP.

A yellow alert means the grid has thin reserves based on the difference between supply and demand.

NGCP data shows the available grid capacity as of 6 a.m. Friday was 10,233 MW against a peak demand of 9,400 MW.

To avoid rotational brownouts, Meralco advised its customers to conserve electricity. – Ted Cordero/VDS, GMA News
