The Visayas power grid will be placed under yellow alert on Saturday afternoon to evening due to thin reserves resulting from the unavailability of several power plants, the National Grid Corporation of the Philippines said.
In an advisory, the NGCP said the yellow alert will be in effect over the islands cluster from 5 p.m. to 8 p.m.
The grid operator said the Visayas grid is currently operating at 2,487 megawatts (MW) capacity against a peak demand of 2,337 MW.
The NGCP cited the following factors that contributed to the yellow alert declaration in the Visayas grid:
• Unavailability of Visayas' large coal plants TVI 1 and TVI 2
• Limited power import from Mindanao (due to maintenance outage of GNPK 2)
