NGCP imposes Mindanao-wide power shedding after bombing

November 12, 2009 9:32 pm 

BUTUAN CITY, Nov. 13 -– Mindanao power consumers suffered power curtailment after the National Grid Corporation of the Philippines (NGCP) imposed its power shedding effective Thursday.

The NGCP imposed its temporary power cut due to the isolation of Agus 1 (40 megawats) and Agus 2 (100 megawats) hydroelectric power plants based in Sitio Taburo, Barangay Nangka, Lanao del Norte.

The said Agus plants were bombed by unidentified gunmen on Wednesday, resulting in rotating brownouts of short durations throughout Mindanao.

Electric cooperatives and private power utilities were requested by the NGCP to voluntarily shed load effective 10:00 a.m. on November 11.

The Abaga-Agus 2138 kilovolt (KV) lines are now unserviceable.

NGCP Mindanao Operations and Maintenance head Emmanuel Abellanosa said the load curtailment is a temporary scheme to keep a manageable supply and demand condition in the grid while it is under some constraints.

“Round-the-clock repairs on damage transmission lines is going on without let up,” he added.

At least seven pylons were already destroyed by unidentified gunmen since last month in Lanao.

NGCP, as the grid operator, is especially looking at the generation reserve level, which should not be less than the on-line plant with the biggest load. The load curtailment scheme affords this crucial flexibility.

The NGCP hopes for the utmost cooperation of its power customers on the load shedding scheme.

The NGCP has mobilized manpower and materials to immediately install an Emergency Restoration System (ERS) to temporarily energize the damaged lines and restore power flow from the Agus plants. The team is just awaiting clearance from the military to enter the bombed site.

As this developed, the NGCP requested security from the Armed Force of the Philippines (AFP) and Philippine National Police (PNP) to help secure power lines in the area, particularly in the repair of damaged pylons.(PNA)
