Located in the province of Benguet. The plant was shut down following an earthquake in 1999. In 2008 SN Aboitiz Power (SNAP) bought the plant and it has since then gone through major rehabilitation that was completed in 2011 with a new installed capacity of 105 MW.
Ambuklao was commissioned by the National Power Corporation in 1956 and is one of the oldest hydropower plants in the Philippines. Initially Ambuklo had a capacity of 75 MW. The usable storage of the Ambuklao reservoir is now 50 MCM (about 45 operating days at 5 peak hours).
A new intake has been built and all major power components, such as turbines and generators, have been replaced. The rehabilitation was completed in the 3rd quarter of 2011. The fully rehabilitated plant has 3 turbines of 35 MW each with a combined average annual production of about 332 GWh.
Sustainable development at Ambuklao
The rehabilitation of Ambuklao, its dam/spillway and other facilities already resulted in a significant number of employment opportunities to local inhabitants. Water quality will be improved by environmental programs to reduce contamination from wastewater and solid waste disposal.
SN Aboitiz Power has established a Corporate Social Responsibility fund to enable strategic development projects in Ambuklao’s host communities. The Fund focuses on supporting self-sustainable and long-term projects within Environmental Management, Eco-tourism, Healthcare, Education and Social Infrastructure. Watershed management programs are currently being implemented to help protect the forests and other areas within the impact area of the plant.
The Ambuklao rehabilitation project has been approved and registered to generate carbon credits under the UN’s Clean Development Mechanism (CDM). Through generation of renewable energy, Ambuklao will replace some of the Philippines’s thermal power production and the UN confirms the project will reduce global CO2 emissions by an estimated 160 000 tonnes annually.
