MANILA, Philippines — The Visayas grid has been placed under red alert until Wednesday night, said the National Grid Corporation of the Philippines (NGCP).
In an advisory, the NGCP said that the red alert started at 5 a.m. and will extend until 9 p.m.
The high alert status was caused by reduced output from Mindanao to Visayas (or the Mindanao-Visayas Interconnection Project) after two power plants — GNPK 2 and SMCPC U2 — tripped.
“Manual load dropping or rotational power interruptions may be implemented to protect the integrity of the power system,” it added.
By 9 p.m., NGCP said the Visayas grid will then transition to yellow alert until 10 p.m.

Meanwhile, a yellow alert is issued when the operating margin is insufficient to meet the transmission grid’s contingency requirement. It does not necessarily result in a power outage.
