The National Grid Corporation of the Philippines said Filipinos can expect uninterrupted power supply this Saturday, with no yellow or red alert declared for any of the country’s three major grids.
NGCP spokesperson Atty. Cynthia Alabanza confirmed the status during an interview on DZRH News program Special on Saturday: “Wala po for today.”
The assurance covers the Luzon, Visayas, and Mindanao grids, all of which fall under NGCP’s transmission monitoring. No alert condition was declared as of Saturday morning, and none was expected through the afternoon and evening.
A yellow alert means the grid’s operating reserve has fallen below the mandated 4% threshold. “Pag yellow alert po, buo pa ‘yung 100 pero kulang na ho ‘yung 4% ng NGCP,” Alabanza explained. A red alert, she said, means a brownout is imminent—triggered when an additional plant trips and the remaining reserve is fully depleted.
“Pag nangyari ho ‘yun, magiging red alert na, at magiging imminent na din po ang power interruption,” she said.
Despite the all-clear for today, Alabanza warned that the remaining weeks of May remain a high-risk period. “Malaki ho talaga ang posibilidad sa panahon ng tag-init,” she said, citing unplanned plant outages as the primary driver of alert conditions over the past eight to ten years.
She noted that heat strains power plant machinery and simultaneously drives up consumption. “Mainit ang panahon kaya maraming gumagamit, malakas ang takbo nung mga turbina, at mas susceptible po sila sa breakdown,” Alabanza said.
NGCP and distribution utilities such as Meralco implement the Interruptible Load Program during yellow alerts, encouraging large power consumers with their own generators to switch to their own units to ease pressure on the grid. “Pag nangyayari ‘yan, marami pong nakikilahok,” Alabanza said of the voluntary program.
Alabanza urged the public to practice energy conservation, noting that reduced consumption helps stabilize supply and lowers household electricity costs.
