CITY OF SAN FERNANDO -- Kapampangans will have to bear with the two to four hours -- and even up to eight hours -- rotating and unscheduled or "instant" brownouts for at least two weeks more.

This was disclosed Friday by the officials of the Department of Energy (DOE) and the National Grid Corporation of the Philippines (NGCP), both said that the rotating brownouts were caused by insufficient energy supply and damaged transmission lines caused by the onslaught of Typhoon Glenda.

NGCP Central Luzon Corporate Communications Officer Ernest Vidal told Sun.Star Pampanga that the transmission company is closely monitoring the power situation in the Luzon grid.

"As of 10:55 yesterday (Thursday), available capacity is at 4,890 megawatts while actual demand is at 4,730 megawatts. To allocate the available power and preserve the integrity of the entire grid, load curtailment is being implemented among distribution utility grid users," he said.

For his part, Energy Secretary Carlos Jericho Petilla said in a report that more than half of the Luzon grid's power supply on Thursday was either unavailable due to plant shutdown or could not be conveyed due to toppled transmission lines.

"About 55 percent of Luzon grid’s total dependable capacity is currently out," Petilla said.

"At the latest, the major lines may be restored by July 22 and then the sublines will follow, and then the distribution lines. There are areas where the restoration down to the households will be faster; there are areas where it will be slower, for various reasons," Petilla added.

Consumers and businessmen in Pampanga are in a quandary as to how long the rotating brownouts will last after it was "immediately as they said it is affecting commerce and industry."

"They should not be happening at all considering what they said before that we have sufficient power supply. It’s either this is artificial and being done on purpose so our energy officials should let us know," the irked businessmen said.

And after the Pampanga 1 Electric Cooperative bared its take on the rotating brownouts, the San Fernando Electric Light and Power Company (Sfelapco) released statements regarding the interruptions.

Sfelapco Corporate Communications Officer Irwin Nucum said in a press release:

"Nais po naming ipabatid sa aming mga konsyumer na ang mga nangyayaring rotational brownout sa Syudad ng San Fernando at Munisipalidad ng Floridablanca ay may malaking kaugnayan sa kakulangan sa power supply at problema sa pagpapadaloy (transmission constraint) ng nalilikhang kuryente ng mga generators bunga ng mga pinsalang dulot ng bagyong Glenda. Ang fluid at dynamic situation na ito ay nararanasan din ng mga kasama nating distribution utilities sa kani-kanilang mga franchise areas sa mga karatig na probinsya,".

Bilang load dispatcher, trabaho ng National Grid Corporation of the Philippines o ng NGCP ang pagtatalaga ng supply ng kuryente pati na rin ang nararapat na brownout kung kinakailangan. May mga pagkakataong biglaan ang pangangailangan upang mabawasan ang tumatakbong kuryente sa mga transmission lines nang sa gayon ay maprotektahan at hindi lubos na mapinsala ang buong grid. Ito po ang dahilan kung bakit may mga pagkakataong hindi na kami nakapagpapalabas pa ng power advisory.

Dahil sa hindi magandang kalagayan ng supply ng kuryente, maaaring magbago ang sitwasyon anumang oras. Maaaring magkaroon ng brownout basta hiningi ng pagkakataon. Ang lahat ng ito ay nakasalalay sa pagdedesisyon ng NGCP. Kaya bilang may ganap na kabatiran sa tunay na kalagayan ng ating power supply, ang NGCP pa rin ang nasa tamang posisyon upang makapagbigay ng pagpapaliwanag sa mga nangyayaring rotational brownout.

Bilang distribution utility, makapagpapaabot lang ng kuryente ang SFELAPCO kung mayroong padadaluying supply ng kuryente ang NGCP sa aming mga distribution lines.

Gayunpaman, buong pagsisikap pa ring magpapadala ng power advisory at maghahatid ng kaukulang impormasyon ang SFELAPCO sa tulong ng Infotext at Facebook para sa kaalaman ng ating mga kostumer. Sa mga ganitong panahon, lubos po nating inaasahan ang unawa at pagtutulungan ng bawat isa. Harinawa’y malampasan na natin sa lalong madaling panahon ang ating dinaranas na kakulangan sa enerhiya. Maraming salamat po." (JTD/Sunnex)
