The National Grid Corporation of the Philippines (NGCP) announced of a scheduled power interruption in parts of Iloilo and Guimaras Provinces on Saturday, April 12, 2025.

The power outage is set from 6 a.m. to 7 a.m., and from 5 p.m. to 6 p.m.

Areas to be affected are ILECO I (Leganes, Bolong and Cabatuan Substations), GUIMELCO (Jordan & Zaldivar Substations) and Guimaras Wind.

The power interruption is due to load transfer from Transformer No. 1 (TR1) to Transformer No. 2 (TR2) and vise versa in order to minimize outage during preventive maintenance activities of the 50MVA TR1 at NGCP's Santa Barbara Substation.

Specific affected areas are determined by the Electric Cooperatives (ECs). NGCP has vowed to exert all efforts to restore power earlier or as scheduled.

"Maintenance activities may finish earlier, hence switching of loads may be done earlier than scheduled," the NGCP advisory reads.
