SMC, K-Water estimate completion of Angat Dam rehab in two years

July 28, 2015

Angat Hydropower Corporation, a local corporation co-owned by San Miguel Corporation (SMC) subsidiary SMC Global Power Holdings Corp. and Korea Water Resources Corporation (K-Water), on Wednesday said it can complete the Angat Dam and Dykes Strengthening Project in two years’ time.

The firm, which operates the Angat Dam multi-purpose hydro facility which generates approximately 246 megawatts of electricity for the Luzon grid of the National Power Corporation (NPC), said the project will involve the fortification of the facility, which supplies an estimated 97% of Metro Manila's raw water requirement.

SMC president and Chief Operating Officer (COO) Ramon S. Ang, said: “This underlines our commitment to participate in projects that will benefit the most number of Filipinos.”

“Water and power supply continue to be pressing concerns for many of our countrymen, and San Miguel is committed to doing its part in improving this vital infrastructure by leveraging our resources and technical expertise, in partnership with K-Water,” he added.

In a briefing to President Benigno S. Aquino III, K-Water President and Chief Executive Officer Choi Gyewoon said that the dam–strengthening plan is based on the dam assessment study done by independent engineering firm Poyry Energy Ltd., which focused on flood safety and structural safety.

The plan has since been reviewed and accepted by all major government stakeholders.

According to the study, in case of an extreme flood event, Angat Dam is safe so long as all three existing spillway gates remain functional.

Thus, the immediate priority is to ensure the proper maintenance of these gates so they continue to operate during floods and remain efficient at lowering the volume of water in the dam.

In the event of a strong earthquake occuring while the dam is nearly full, mitigating measures proposed by Poyry consist of:

  • Raising the impervious or clay portion of the core of the main dam by 1.2 meters to substantially improve the overall strength of the dam.
  • Widening the base and the downstream slope of the dam and dykes using rockfill from a nearby quarry used during the original construction of the Angat dam. The new slope will increase from 1:1.40 to 1:1.55 in proportion.

"We hope that this undertaking only strengthens our already deeply rooted friendship. I hope that in the future we can exchange water-related technologies, given that water security challenges are on top of the agenda of the governments of many developing countries," he added.

The project is part of the Operations and Management Agreement with the Private Sector Assets and Liabilities Management (PSALM) and the National Power Corporation (NPC).

K-water won the bidding for the Angat Hydroelectric Power Plant (AHEPP) in 2010. SMC Global Power joined K-Water as it acquired 60 percent of K-Water’s Angat Hydropower Corporation, which took active management of the AHEPP in November 2014.

Angat Dam provides 500 million gallons of water per day to millions of households and businesses and irrigates 25,000 hectares of farmlands in Bulacan and Pampanga.
