Landowner cuts Agus 1 from power grid


Almost 30 megawatts (MW) from the Agus 1 hydroelectric plant was temporarily unavailable to the Mindanao grid on Tuesday after an uncooperative landowner refused to allow line maintenance and repair activities, the National Grid Corp. of the Philippines (NGCP) said .

It identified the landowner as Mitmug Dimaampao, said to be the “same landowner who previously barred NGCP linemen from entering the property to cut trees which obstruct the transmission lines.”

The NGCP said the plant was isolated from the grid at 9:14 a.m. when the Agus 2 and Agus 1 138-kV tie line tripped. The line was finally energized from the Agus 2 switchyard side at 11:37 a.m., it added.

The tie line is operated and maintained by state-owned National Power Corp. (NPC). Private concessionaire NGCP helped restore the power.

The NGCP reiterated an appeal for public cooperation and warned that right of way violations along transmission lines were compromising not just the safety of the people but also the security of the power grid.

“Because of Mindanao’s current power situation, the isolation of any power plant from the grid may result in more load curtailment during peak hours to allocate whatever power is available to the rest of the customers,” said NGCP.

The Energy department has also called on landowners to allow NGCP personnel to enter their premises to repair transmission facilities damaged this month by Typhoon Lando.

It also called on local government units to help the NGCP address right-of-way disputes, adding that all stakeholders had to support and assist the department’s mandate of ensuring sufficient and reliable power supplies.

The NGCP has complained of uncooperative landowners who refuse to allow personnel to clear fallen trees and vegetation, which could cause power lines to trip.
