Rotational brownouts hit parts of Luzon after NGCP raises red alert

Grid instability returns amid peak summer demand.

Residents in several parts of Luzon experienced power interruptions today after the National Grid Corporation of the Philippines raised a red alert status over the Luzon grid due to insufficient power supply and reserves from multiple power plants.

According to advisories shared by Meralco and reposted by UNTV News and Rescue, rotational brownouts lasting up to two hours were implemented in affected areas beginning around 3 PM.

Meralco said affected communities may experience outages between 3:01 PM and 8 PM as the grid operator struggles to maintain enough electricity reserves amid high demand and limited available supply.

The power distributor urged consumers to expect temporary interruptions while authorities manage the situation and stabilize the Luzon grid.

Understanding the red alert

A red alert status is declared when the power supply available for the grid becomes insufficient to meet consumer demand and required reserves, increasing the possibility of widespread outages or manual load dropping.

The development immediately triggered concern online, with many Filipinos expressing frustration over recurring brownouts and the impact of outages on work, businesses, internet connectivity, and daily activities during the intense summer heat.

Meralco advised affected customers to monitor its official social media pages for updates regarding the schedule and duration of interruptions in their respective areas.
