Name: Magat Hydro
Capacity: 360 MW
Location: Ramon, Isabela
Commisioning: August 1983
Description: The Magat Hydroelectric Power Plant is among the largest in Luzon, which is one of three main islands of the Philippines. The facility draws water from the Magat River through the multi-purpose Magat dam.

Though used for power generation and flood control, the dam’s primary purpose is to irrigate around 85,000 hectares of agricultural lands in Cagayan Valley, mostly in Isabela Province. Only the power components of the facility were privatized; the Magat dam and its re-regulating facilities downstream are owned and maintained by the National Irrigation Administration (NIA), a government corporation. The power plant uses the same water needed for irrigation and its use of water from the dam is dependent on NIA’s irrigation diversion requirement.

Magat operates as a peaking plant; a portion of its output has power purchase agreements with electric utilities while the rest is sold to the Wholesale Electricity Spot Market. It is also capable of providing ancillary services necessary for for the grid’s reliability & stability.

Magat HEPP is undergoing half-life refurbishment targeted to be completed by 2014 to preserve the units’ remaining life and continuance of its availability.

The Magat plant is an Occupational Health and Safety Assessment Series (OHSAS) 18001:2007 and Quality Management System (QMS) ISO 9001-certified facility. It has also received the ISO 14001:2004 certificate for its Environmental Management System (EMS).


Name: Ambuklao Hydro
Capacity: 105 MW
Location: Itogon, Benguet
Commisioning: December 1956, July 2011
Description: Ambuklao was the first among the largest hydroelectric power plants constructed in the Philippines and is one of the oldest. The facility was constructed for power generation and flood control and runs along the upper portion of Luzon’s third largest river, the Agno.

In July 1990, a strong earthquake hit Luzon resulting in siltation and technical problems that affected the plant’s operations. Ambuklao was eventually decommissioned in 1999.

When SNAP-Benguet took over in 2008, it began a massive rehabilitation project that restored Ambuklao to operating status and increased its capacity from 75 MW to 105 MW. The project required the construction of a new intake, headrace and penstock, elevation of tailrace tunnel outlet, de-silting of tailrace tunnel and replacement of electro-mechanical components. In June 2011, Unit 3 became the first turbine units to go on-line, followed by the other two units. Ambuklao was formally inaugurated in October 2011.

The Ambuklao power plant is designed as a peaking plant capable of delivering energy and providing ancillary services needed for for the grid’s reliability & stability.

The plant’s health and safety, quality, and environmental management systems are internationally certified under OHSAS 18001:2007, ISO 9001, and ISO 14001:2004, respectively.
Name: Binga Hydro
Capacity: 140 MW
Location: Itogon, Benguet
Commisioning: January 1960, July 2013
Description: Built four years after Ambuklao, the Binga facility was also constructed for power generation and flood control and lies 19 kilometers downstream of Ambuklao.

The electricity generated by Binga is traded at the Wholesale Electricity Spot Market. Binga is also capable of providing ancillary services necessary for the grid’s reliability & stability.

SNAP-Benguet inaugurated the Binga Hydroelectric Power Plant in October 2013 after almost three years of refurbishment work that entailed the construction of a new headrace and intake, modernization of plant control systems, replacement of electro-mechanical components, and installation of new auxiliary equipment.

The Binga plant is certified under OHSAS 18001:2007 (health & safety management), ISO 9001 (quality management), and ISO 14001:2004 (environmental management).

Both Ambuklao and Binga were registered in 2011 as Clean Development Mechanism projects by the United Nations Framework Convention on Climate Change. Together they can produce an average of 180,000 carbon emission credits per year.

New Projects

Maris Canal Hydro Project

SN Aboitiz Power-Magat, Inc. (SNAP Magat) and National Irrigation Administration (NIA) have signed a Memorandum of Understanding for SNAP Magat to develop the proposed 6-MW Maris South Canal and 1.75-MW Maris North Canal mini-hydropower projects.

This was after SNAP-Greenfiled secured renewable energy service contracts (RESCs) from the DOE for the two projects in December 2013. SNAP-Greenfield is currently waiting for DOE’s approval of the assignment of the RESCs to SNAP-Magat.

Ifugao Hydro Project

SNAP-Ifugao secured RESCs for its proposed 350-MW hydropower complex project in Ifugao, which is composed of three facilities: the 100- MW Alimit and 10-MW Olilicon plants, and the 240-MW Alimit pumped storage facility. Both the Maris and Alimit projects are currently in the feasibility study stage.
