MORE Electric and Power Corporation (More Power) has announced that several areas in Iloilo City may experience rotational brownouts lasting between two to three hours. This development comes after the National Grid Corporation of the Philippines (NGCP) requested the implementation of Manual Load Dropping (MLD) in the Visayas Grid due to a supply deficiency.
The MLD will be in effect from 4 p.m. to 11 p.m. on May 15, 2026, as the Visayas grid faces a red alert status. More Power stated that the red alert may trigger MLD and temporary power interruptions in areas connected to selected substations and feeders throughout the city.
In an advisory, More Power said: “NGCP has requested the implementation of MANUAL LOAD DROPPING (MLD) in the Visayas Grid due to a supply deficiency from 4 p.m. to 11 p.m.” The company added: “There is a possibility of Manual Load Dropping (MLD) and rotational brownouts, which may cause power interruptions lasting approximately 2–3 hours in the areas listed below during the red alert status.”
Affected Areas and Substations
The affected areas include feeders under the Megaworld, Molo, La Paz, Jaro, and Diversion substations. Specifically, under the Megaworld Substation, Feeders 2, 3, and 6 are affected. The Molo Substation covers Feeders 1 and 5, while the La Paz Substation includes Feeders 4 and 7.

More Power said it will continue to monitor the situation and release updates as necessary. “We will continue to provide updates as more information becomes available. Thank you for your understanding and cooperation,” the company stated.
Background and Consumer Advisory
The advisory comes as the Visayas grid continues to face power supply challenges, prompting the NGCP to implement measures to stabilize the transmission system and prevent a regional blackout.

More Power personnel are actively monitoring the power distribution system in Iloilo City to manage the situation effectively.
