THE National Grid Corp. of the Philippines (NGCP) expects a longer time to restore power in areas affected by the toppling of transmission tower in Patani, Marawi City.
”It seems it will take a while,” Faye de Jesus of the corporate communications office of the NGCP said.
An explosion toppled down NGCP’s transmission tower in Patani, Marawi City on Thursday evening, causing the Mindanao grid to lose a capacity of 150 megawatts (MW) since the tower held transmission lines connecting the Agus 1 and 2 to the Mindanao grid.
Consequently, Davao Light and Power Co., the distribution utility owned by Aboitiz Power Corp., implemented two-hour rotating brownouts in its franchise area due to the grid isolation.
The NGCP reported on Friday that the two hydro-electric power units were isolated from the grid at around 9:20 p.m. on Thursday.
The transmission firm, however, explained “it cannot identify the specific areas affected because the deficiency is spread out across the Mindanao grid.”
The grid operator added it will begin restoration activities as soon as the area is secured.
The Philippine Army, through the 1st Infantry Division, has arrived in the area to secure it.
On Tuesday, about 30 MW of power from the Agus 1 was disconnected from the Mindanao grid as an uncooperative landowner refused entry for NGCP personnel to conduct line maintenance and repair activities inside his property.
The NGCP identified the landowner as a Mitmug Dimaampao, adding that he is the same landowner who stopped their linemen from cutting trees in his property, which obstructed the transmission line.
