MANILA, Philippines — The Senate Committee on Energy will launch an inquiry into the recent spate of rotational blackouts in Luzon, the panel's chairman, Sen. Sherwin Gatchalian, said Wednesday night.
Some 390,000 households from 90 barangays in 16 LGUs lost their electricity on June 1, Gatchalian said.
Two vaccination centers in Valenzuela, he added, also experienced power interruptions.
A number of senators were also unable to attend Tuesday's plenary session through videoconference due to the blackouts.
In another plenary session held the following day, several senators noted that the Department of Energy in April assured the Senate that there was no high risk of power shortage supply during the summer.
Gatchalian said he filed Senate Resolution No. 740 to underscore the role of the DOE in ensuring the quality, reliability, security and affordability of electric power supply in the country and to hold the department to account for its failure to address power supply shortages since 2016.
The National Grid Corp. of the Philippines (NGCP) on Monday raised the red alert warning, meaning there is severe power deficiency that could lead to rotational power interruptions, on the Luzon power grid from 2 p.m. to 4 p.m.
Meanwhile, a yellow alert notice was raised from 11 a.m. to 2 p.m. and 4 p.m. to 5 p.m. This means there were not enough reserves to cover the largest running generating unit in those hours.
Amid all this, Energy Secretary Alfonso Cusi was in Cebu, presiding over a national council meeting of the ruling PDP-Laban as its vice chairman.
"[I] it is crucial for the DOE to provide long-term solutions to this problem and a specific timeline for these plans, to include the hastening of the build out of new power plants, aggressively utilizing energy efficiency and conservation, and contracting sufficient ancillary reserves," Gatchalian said in a statement released by his office.
"All these things are necessary to protect the public and the economy from losses due to power outages and the resulting high prices of electricity due to limited power supply."
