Philippines - Success in a booming hydropower market

According to International Monetary Fund (IMF), the Philippines will be the most rapidly growing economy in Southeast Asia in 2015 and 2016.

Due to this economic growth, which comes along with an increase in population, consumption and energy demand, the Philippines face an enormous challenge regarding electrical energy supply.

The most radical transformation of the Philippine power sector was the restructuring under the auspices of the Electric Power Industry Reform Act (EPIRA) in 2001, which included the breakup of a government monopoly, encouraged the entry of many private players and generated market competition. With the Renewable Energy Act of 2008, a policy was created to define substantive feed-in tariffs (FIT) for hydroelectric power, in order to show the viability of potential projects to developers and investors.

Electricity production in the Philippines is still dominated by thermal resources (natural gas and coal), although hydropower is by far the largest renewable energy source with an actual total share of 20%.

ANDRITZ HYDRO in the Philippines

In the Philippines ANDRITZ HYDRO has mainly focused on small hydro installations during the last five years. In recent years the following Philippine orders were received:

Irisan 1

In 2010, ANDRITZ HYDRO received an order from Hedcor Inc., a subsidiary of AboitizPower, to deliver the complete electro-mechanical package, including installation and commissioning, for HPP Irisan 1. The design of the site, especially the buried penstock leading to the powerhouse, took into consideration the needs of local farmers. Since November 2011, the vertical four-jet Pelton turbine has been producing renewable energy.

Tudaya 1 and 2

As a result of the successful cooperation with Hedcor Inc. at the Irisan1 project, ANDRITZ HYDRO was assigned to deliver the complete electro-mechanical equipment for HPP Tudaya 1 (one Compact Pelton turbine) and HPP Tudaya 2 (two Compact Francis turbines of different sizes) in 2012. For HPP Tudaya 2 the customer has the intention to develop the powerhouse compound into a visitor center with a focus on schools and universities to show how to develop and operate hydropower plants.


In May 2013, another contract was signed with Hedcor Inc. The scope of supply consists of two identical, vertical, six-jet 7.4 MW Pelton turbines and a complete water-to-wire package. HPP Sabangan has a 3.2 km waterway system from the intake weir to the powerhouse.

Manolo Fortich 1 and 2

ANDRITZ HYDRO continued its success in the Philippines receiving contracts for HPP Manolo Fortich 1 and 2 (see Hydro News 27). Two cascading plants will be built harnessing power from the rivers Amusig, Guihean and Tanaon on the island of Mindanao. The start of the equipment delivery for HPP Manolo Fortich 1
(44.4 MW) is planned for the end of 2016, for HPP Manolo Fortich 2 (26.1 MW) the supply is scheduled for beginning of 2017.


In 2011 ANDRITZ HYDRO signed a contract with Sunwest Water and Electric Co. Inc., part of the Sunwest Group of Companies. The 8 MW Villasiga hydropower project consists of two 3.60 MW and one 800 kW Francis turbines. Despite the site being hit by several natural disasters, ANDRITZ HYDRO is determined to complete the project and to bring the plant online.


The contract for the supply of the complete electro-mechanical works for HPP Catuiran was signed with Sta. Clara International Corp., a well-known Philippine business conglomerate, in November 2014. HPP Catuiran is located on the island of Oriental Mindoro and will generate 2 x 4 MW of renewable energy. Start of operation is scheduled 17 months after contract signature in early 2016.

The Philippines have an undeveloped hydropower potential of more than
13,000 MW. ANDRITZ HYDRO is looking forward to being a part of the development of this renewable energy source.
