Two voltage fluctuations preceded the blackout, giving rise to speculation that this is

Another sabotage attack on the transmission towers of the National Grid Corporation of

The Philippines, ( NGCP )


It comes at a time when the reserve capacity for the Mindanao Grid fell to a low 35 MW.

The Available Capacity for today was 1,330 MW, compared to the all-time high Peak

Demand of 1,295 MW.
