Visayas consumers face rotating brownouts anew on Wednesday, June 3, 2026

Power consumers in the Visayas should brace for rotating brownouts once again on Wednesday afternoon to evening due to thin power reserves.

In an advisory, the National Grid Corporation of the Philippines (NGCP) said it might implement manual load dropping (MLD) or rotational brownouts from 2 p.m. to 8 p.m. “to maintain the integrity of the power system” in the following areas:

VECO
MECO
CEBECO I
CEBECO II
CEBECO III
NEPC
NOCECO
NORECO I
NORECO II
NONECO
MORE
AKELCO
ANTECO
CAPELCO
ILECO I
ILECO II
ILECO III
GUIMELCO
BLCI
BOHECO I
BOHECO II

The NGCP said the factors that contributed to the implementation of the MLD is the limited generation in Cebu-Negros-Panay sub-grids.

“Schedule may be cancelled if system condition improves, such as if actual demand falls below projections. NGCP encourages everyone to exercise prudence in using electricity,” the grid operator said.

The NGCP placed the Visayas grid under yellow alert from 4 p.m. to 9 p.m. as the islands-cluster is operating at an available capacity of 2,552 megawatts (MW) against a peak demand of 2,392 MW, while a total of 985.5 MW is unavailable to the grid due to the forced outage and derated capacities of several power plants.

A yellow alert is issued when the operating margin is insufficient to meet the transmission grid’s contingency requirement.

While supply is still enough to meet current demand, it no longer reaches the required safety margin.

At this level, the possibility of rotational power interruptions increases. — Ted Cordero/BM, GMA News
