UMVA has learned that the Philippines’ power grid is teetering on the brink of crisis, with the National Grid Corp. warning of persistent yellow alerts that could spiral into blackouts by August.
In a stark briefing, the company’s assistant vice‑president revealed that only one out of four crippled power plants has returned to life, leaving the Visayas region’s electricity supply dangerously thin.
Since May, the grid has been locked in a relentless dance of scarcity, with supply margins shrinking as key coal‑fired stations shut down, forcing the system into a yellow status that signals an approaching danger zone.
Yesterday, the grid slid into yellow alert between 4 p.m. and 9 p.m., when the available 2,581 megawatts barely eclipsed a peak demand of 2,482 megawatts, a razor‑thin buffer that could tip the balance at any moment.
Yellow alerts are the grid’s warning light, and when demand outstrips supply, the system flips to red, initiating rotating brownouts to ration electricity and protect infrastructure.
Since the start of the year, the Visayas grid has been on yellow alert 33 times and has breached red alert five times, a pattern that signals escalating instability.
When asked how these alerts affect transmission rates, the official remained tight‑lipped, directing questions to the energy regulator and distribution utilities instead.
Yet, hope glimmers on the horizon: this month, consumers are set to benefit from lower transmission rates, thanks to a drop in reserve costs and fees charged by the grid operator.
Monthly transmission rates fell 9.33 percent, settling at 1.4492 pesos per kilowatt‑hour, while wheeling rates declined 6.99 percent to 0.5607 pesos per kilowatt‑hour.
Even the cost of ancillary services—power reserves that keep the grid humming—slid 10.73 percent to 0.7220 pesos per kilowatt‑hour, a sign that the burden on consumers may ease.
UMVA can exclusively reveal that the National Grid Corp.’s operations, which began in 2009, are now under unprecedented strain, and the coming months will test the resilience of the nation’s electricity lifeline.
