The Angat Hydro-Electric Powerplant (AHEPP) will undergo a temporary two-month shutdown for repairs and rehabilitation.
The Metropolitan Waterworks and Sewerage System (MWSS) said the shutdown is aimed at enhancing the efficiency and reliability of the AHEPP.
The repairs and rehabilitation project will be implemented by the Angat Hydropower Corp., which will last for 61 days, starting from Nov. 6, 2023, and ending on Jan. 6, 2024.
MWSS said the main objective is to prolong the lifespan of the powerplant and ensure a steady water supply for domestic and irrigation purposes.
The AHEPP is a joint-venture asset of San Miguel Global Power Holdings Corp. and Korea Water Resources Corp.
It has a generating capacity of 218 megawatts and consists of four main units and three auxiliary units.
Angat hydropower plant to temporarily close for repairs

The Metropolitan Waterworks and Sewerage System (MWSS) has announced that the Angat Hydro-Electric Powerplant (AHEPP) will undergo a temporary shutdown of two-months to make way for its repairs and rehabilitation.
In an effort to enhance the efficiency and reliability of the AHEPP, the MWSS stated that the Angat Hydropower Corp. will undertake a major repairs and rehabilitation project for 61 days, starting from Nov. 6, 2023, until Jan. 6, 2024.
The main objective of the total plant shutdown (TPS) is to prolong the lifespan of the powerplant and ensure a steady water supply for both domestic and irrigation purposes, the MWSS said.
According to the agency, the AHEPP would work on the existing penstock, a crucial component of the powerplant's infrastructure that is responsible for delivering water to the turbines.
Recognizing the potential impact of the TPS on water supply, the MWSS has taken measures to ensure a continuous water supply for domestic and irrigation purposes throughout the shutdown period.
Collaborating closely with Maynilad Water Services Inc. and Manila Water Co. Inc., MWSS has developed comprehensive guidelines for the operation of the Angat Dam spillway and low-level outlet.
These guidelines were unanimously agreed upon by the Interagency Technical Working Group on Angat Dam Operations and Management.
The technical working group comprises representatives from the National Water Resources Board (NWRB), the National Power Corp. (NPC), the National Irrigation Administration (NIA), MWSS, Maynilad, Manila Water, and Angat Hydropower.
The guidelines will serve as a roadmap for effectively managing the water flow from the Angat Dam during the TPS.
Currently, the water level of the Angat Reservoir stands at 209.48 meters, in close proximity to its Normal High-Water Level (NHWL) of 210 meters.
This favorable water level assures MWSS of an ample supply of raw water for its service areas, which encompass the bustling metropolis of Metro Manila, as well as the provinces of Bulacan, Cavite, and Rizal.
AHEPP is a hydropower facility operated by Angat Hydropower, a joint venture between San Miguel Global Power Holdings Corp. and Korea Water Resources Corp.
It has a generating capacity of 218 megawatts and consists of four main units and three auxiliary units.
