NGCP implements rotational blackouts in Meralco areas

The National Grid Corp. of the Philippines (NGCP) implemented rotational power interruptions in Meralco's franchise area on June 1, 2021, due to a thin power supply from the Luzon grid.

These brownouts, also known as manual load dropping (MLD), are a measure to maintain the integrity of the power system.

The Luzon grid was placed under Yellow Alert from 8 a.m. to 9 a.m., 5 p.m. to 6 p.m., and 11 p.m. to 12 a.m., and under Red Alert from 9 a.m. to 5 p.m. and 6 p.m. to 11 p.m. on June 2, 2021.

This indicates zero ancillary services or a generation deficiency, with available capacity at 11,260 megawatts against an operating requirement of 11,976MW, resulting in a deficiency of -716MW.

Affected areas in Bulacan included parts of Angat, Bustos, and Pandi on June 1, and several specific barangays across Angat, Balagtas, Bocaue, Bustos, Pandi, San Jose del Monte City, and Santa Maria on June 2.

Several towns and cities in Cavite, such as Amadeo, Dasmarinas City, Gen. M. Alvarez, General Trias City, and Silang, also experienced these power interruptions on June 1.
