Utility crews scrambled to repair thousands of toppled power pylons as well as transmission lines as the death toll from Typhoon Rammasun, the first major storm of the Southeast Asian archipelago's rainy season, inched up.
"It will take two weeks for power to normalise to pre-typhoon level for everyone," Energy Secretary Jericho Petilla told reporters, conceding that progress in restoration work was slow.
Meanwhile the authorities expressed frustration amid signs many of those who died had ignored government warnings about the dangers posed by the typhoon, one of 20 forecast to hit the Asian archipelago this year.
As part of a "zero casualty" effort, the government evacuated nearly 400,000 people from the path of Rammasun and warned others to stay indoors.

Manila's power distributor said it did not expect to have power fully restored to the humid capital and surrounding areas until late tomorrow.
