MANILA, Sept. 11 –Starting today, the state-run National Power Corp. (Napocor) will enforce a rotating brownouts in Mindanao as the Mindanao Grid suffers a temporary power supply shortage.

Napocor, in a statement, said its four power generating facilities and a plant each from two independent power producers in Mindanao had been temporarily shut down due to a variety of reasons.

Napocor said the shutdown, which started today, resulted in deficient capacity to meet the Mindanao Grid’s electricity demand.

It also said that rotating brownouts had to be implemented during peak hours. But power supply would be normal during off-peak hours.

“We apologize and request the patience of our customers and the electricity consuming public. Your National Power is doing all that it can to bring power supply back to normal, and we are optimistic to make it happen soon,” the Napocor statement said.

Napocor said the decrease in capacity were due to the tripping of Agus 1's unit 2 with 40 megawatts MW) generating capacity in Marawi, Lanao del Sur last Aug. 10, and the shutdown of the 100-MW Western Mindanao Power Corp. (WMPC) and the Unit 1 of Mindanao (STEAG) Coal plant.

The shutdown of the two plants by independent power producers also coincided with the the scheduled preventive maintenance operations of Agus 2 (Unit 1, 60 MW)in Saguiaran, Lanao del Sur; Agus 5 (Unit 1, 27.5 MW) in Iligan City; and Pulangi 4 (Unit 1, 85 MW) in Maramag, Bukidnon;

”Overall, more than 400 MW out of a total of 620 MW dependable capacity were affected,” the agency said.

But Napocor assured that the ongoing scheduled preventive maintenance operations will, in the long-run, yield more reliable and stable power supply for the grid.

Also, the WMPC has already put on-line two 10-MW units out of 10 units. It is also undertaking round-the-clock operations to put back its normal dependable capacity on-line in the soonest possible time.

“Our people are working round the clock, and continuously coordinating with the proper agencies such as the National Grid Corporation of the Philippines, and our customers involved in power distribution for updates on the power supply situation. Hopefully, we will already have a normal power situation by September 26, 2009,” Napocor further said.

Napocor did not give any time table on the completion of the rehabilitation and maintenance of the plants as well as how many hours the rotating brownouts will last. (PNA)
