Stable power supply seen as Lake Lanao water level goes up

SHORT of assuring the public there would not be a repeat of the brownouts that devastated Mindanao last summer, the National Power Corp. (Napocor) said Lake Lanao would attain its ideal water level soon, assuring a steady supply of electricity in the next year’s dry months.

“The water level at Lake Lanao has now reached 700.89 meters and we believe it would attain the ideal level target of 701.10 meters by year end, given present trends in the weather,” said Engr. Jerese Irese Lagapa, department manager of Napocor’s Operations and Dispatch Department which controls the dispatch of electricity from the various power plants of the Mindanao power grid.

Responding to questions regarding last summer’s power crisis at the Mindanao Power Crisis Forum hosted Sept. 16 by Xavier University, Lagapa also dispelled persistent reports that the power crisis which hit Mindanao was deliberate and man-made.

“We have shifted from the previous minimum thermal mode of operation to using the operational rule curve since 2004,” Lagapa said.

She said the water level of Lake Lanao for the last quarter of 2009 was very low due to the onset of the El Niño phenomenon and a confluence of other factors, but not because it was deliberately depleted by Napocor personnel.

The questions regarding the water level at Lake Lanao arose following a presentation by Therma Marine Inc. (TMI) executive vice president and chief operations officer Jovy Batiquin on the controversial Ancillary Services Power Agreement (Aspa) between TMI and the National Grid Corp. of the Philippines (NGCP).

Batiquin said the two power barges acquired by TMI from Napocor had been put “in the garage, with engine running and driver ready to go” but had not been dispatched by NGCP despite the occurrence of a power deficiency in the Mindanao grid earlier this week.

Rotating brownouts again hit Southern Mindanao earlier this week following the scheduled commissioning of the Maramag-Kibawe 138-kilovolt transmission line by the NGCP and a call for voluntary load curtailment in Cotabato province, fuelling fears that a “scenario” was being deliberately played out in Mindanao to pave the way for a price increase in generation and transmission tariffs.

Both Napocor and NGCP have pending applications for rate hikes with the Energy Regulatory Commission (ERC).

‘Information Crisis’

Participants in the open forum appealed to Napocor and the energy department to be more transparent in updating the public especially consumers about the latest power situation in Mindanao to avoid needless speculations.

Meanwhile, Xavier University president Jose Ramon Villarin said the “real crisis” is on “information”.

Power curtailment hits Mindanao anew

ZAMBOANGA CITY, Philippines-
Power curtailment has again hit a vast area of Mindanao just as President Aquino expressed hope that he could end the power crisis on the vast island before his term ends in 2016.

This, as the National Grid Corporation of the Philippines (NGCP) issued a red alert notice not because of dwindling water levels but of technical problems in power plants.

Mindanao, which is largely dependent on hydroelectric power, has been experiencing power shortage due to low water supply since February due to the El Niño-caused dry spell.

In an alert notice issued to the Zamboanga City Electric Cooperative (Zamcelco), NGCP manager Reynerio Ramos said two-hour curtailment in the power supply will again be experienced daily.

The NCGP said it issued the red alert notice effective yesterday, explaining that its contingency reserve is already zero due to planned outage of the Pulangi 4 hydroelectric power plant; the Agus 6, which is supplying only 20 megawatts; and the emergency shutdown of Agus 2.

The power curtailment was also due to the reduced capability of the Agus power plants and the Pulangi hydroelectric plant.

The non-operation of the APTM1 and APTM2 power barges due to transmission line constraints also contributed to the power curtailment.

Mr. Aquino, who was in Davao del Sur Thursday to inaugurate the 42.5-MW Sibulan hydropower project, which is seen to make a significant contribution to the Mindanao power grid, was hoping the power crisis in Mindanao, which he described as a “nightmare,” would be over soon.
