TAGBILARAN CITY – The entire province of Bohol plunged into darkness early yesterday morning for still unknow causes that resulted to a total blackout for more than eight hours. The National Grid Corporation of the Philippines (NGCP) said that it tried to find out the cause of the blackout at early morning yesterday. “Investigation and analysis of the root cause of the loss of power is on-going,” NGCP said in its text advisory message.
In its advisory, NGCP said “power interruption was experienced in Bohol-Cebu-Leyte-Samar areas at 1:25 AM on Feb, 19, 2015.” But after eight hours of power loss, restoration of power transmission services in the Visayas grid has been completed at 9:09 AM yesterday, it said. Bohol was not the only island affected by the blackout but also the islands of Samar, Leyte and Cebu, NGCP said.
The blackout has shutdown some industries, like those in printing and publications that used electricity during those hours. The province of Bohol remains vulnerable to this kind of power interruption as it has no island-based power generation. It largely and contiuously depends on the Leyte-Bohol Geothermal from Tongonan, Leyte as its power demand is growing.
A combined power generation to a little over 20 megawatts (MW) from its sources — Dampas Diesel Power plants and hydro power plants in Loboc, Sevilla and Hanopol — appeared cannot meet the demand of more than 65 MW. This situation prompted business establishments in this city and towns, including tourist-related resorts, to resort to have its own generating power sets in the event of blackout. (rvo)
