Efficient power use urged amid questions on supply, outlook

"The high and increasing heat index triggered the unusual rise in demand for power, where Luzon alone reached around 9,700 megawatts (MW) breaching historical records," the DoE said in a statement on Sunday.

The department said it "earnestly calls on the cooperation of electricity consumers to be efficient users not only during the summer period."

"Historically, power consumption spikes during hot summer months as more consumers spend time in their homes and use cooling equipment to make them feel comfortable," it added.

The DoE did not immediately respond to questions about the power outlook or whether Friday's "red alert" would be a recurring incident in the coming days.

In a text message, Manila Electric Co. (Meralco) said there would be no rotational brownout on Sunday.

On Twitter, Meralco only advised of areas that would be affected on Sunday of its scheduled maintenance. These are portions of Malakas St. from V. Luna Ave. to Magalang St. including The Church of Jesus Christ in the Latter Day Saints and CPRM Building in Barangay Pinyahan, Quezon City, including the Land Transportation Office central office along East Ave.

It said the occurrence was between 10:00 a.m. and 3:30 p.m. because of a replacement of rotten pole relocation of primary line and line reconductoring works along Malakas St. in the said barangay.

On the same day, it also advised of line maintenance works along Eduque Street in Barangay Poblacion, Makati City between 9:00 a.m. and 2:00 p.m.

Last Friday, Meralco expected "red alert" from 1:00 p.m.-4:00 p.m., with tentative "manual load dropping" -- or power cutoff in some served areas due to power supply shortage -- scheduled from 1:00 p.m.

It called on participants of the interruptible load program (ILP) to start deloading at 1:00 p.m. to help reduce power demand.

Under the ILP, big load customers of distribution utilities and electric cooperatives run their standby generation sets in times of energy supply deficiency to prevent power outages.

The DoE expressed its appreciation to the National Grid Corporation of the Philippines (NGCP), Meralco and the ILP participants "for their cooperation in hurdling a critical power supply situation in Luzon."

The ILP was implemented in the Meralco area to stabilize the power supply situation following the "red alert" notice of NGCP from 1:00 p.m. to 3:00 p.m. last Friday.

With the program, "the peak demand was arrested at a lower level of 9,416 MW. A total of 247 MW of power was deloaded from 121 participants, so an estimated 290,000 customers in Metro Manila and nearby provinces were spared of rotating brownouts," the DoE said.
