MANILA, Philippines - State-owned National Power Corp. (Napocor) will temporarily shut down operations of the 218-megawatt (MW) Angat Hydroelectric Power Plant from September 28-29.
"It will take effect to undergo repairs, specifically of a bypass valve that goes to its auxiliary unit. The shutdown will be for two days, until September 29, 2010," Napocor said in a statement.
Napocor said the repairs are needed to maintain the integrity of the level of control over the water supply in the reservoir.
The shutdown is expected to affect water supply to the two water concessionaires in Metro Manila, namely Manila Water and Maynilad.
An agreement signed by various stakeholders said there will be no effect on water supply for the first day of the shutdown.
On the second day of shutdown, it is agreed that Maynilad's water requirements of 2,150 million liters a day (MLD) shall be sourced from its dedicated aqueducts while Manila Water's requirements shall be sourced from both its own dedicated aqueducts and the La Mesa Dam.
After the two-day shutdown, Napocor will replenish the volume of water reduced and will release the normal requirements for both concessionaires.
The shutdown of the power plant will not have any significant effect on the country's power supply.
