MANILA, Philippines – Government has turned to more cloud-seeding operations to induce rains that will hopefully replenish or raise water levels in various dams all over Luzon and Mindanao.
National Power Corporation (Napocor) president Gladys Cruz Sta. Rita said a cloud-seeding operation targeting Angat Dam will be done this week to the tune of P2.6 million for 50 sorties.
Angat Dam, the primary source of potable water for Metro Manila, has seen its water level fall since the beginning of summer.
The water level at Angat stood at 182.2 meters as of 6 a.m. Monday, nearing the minimum operating level or critical level of 180 meters.
When asked if the situation is already alarming, Sta. Rita said we should all be cautious and make it a point to save water as the dry spell may be prolonged until after summer season.
Sta. Rita hopes the induced rain will fall directly into the dam but if not, she said it will still help cool the weather.
A degree centigrade drop in temperature means a reduction of 100 megawatts in power demand, she said.
Other dams in Luzon being monitored are as follows:
Ambuklao current level: 740.82 m; critical level: 740 m
Binga current level: 569.68 m; critical level: 566 m
San Roque current level: 239.8 m; critical level: 225 m
Magat current level: 169.68 m; critical level: 160 m
Cloud-seeding operations will also be conducted for Mindanao as the hydro-plants are also nearing critical levels.
More than half of Mindanao's power source comes from hydro facilities.
Below are the levels of water in Mindanao's hydro-power plants:
Lake Lanao current level: 699.49 m; critical level: 699.15 m
Pulangi 4 current level: 282.01 m; critical level: 282 m
Agus 4 current level: 357.28 m; critical level 357 m
According to Sta. Rita, it follows that with reduced levels of the water from the hydro complex, power generated will also be decreased.
However, she refused to specify how much power was shaved from the already deficient power supply in Mindanao.
