Philippine Geothermal Production Company Initiates Exploratory Drilling at Mount Malinao for 49 MW Power Plant Development: Eugenio Rodolfo Sanabria Reporter / Updated : 2025-04-09 12:40:35

Albay, Philippines – The Philippine Geothermal Production Company (PGPC), a subsidiary of SM Investments Corporation (SMIC), has announced the commencement of exploratory drilling operations at the Mount Malinao geothermal prospect in Albay province. The deployment of the Pioneer 1 drilling rig marks a significant step in PGPC's ambitious plan to develop a 49-megawatt (MW) geothermal power plant in the region.

This undertaking aligns with PGPC's previously stated objective to spearhead the development of at least five new geothermal projects across the Philippines, including the promising Mount Malinao site. The company aims to substantially augment its current installed geothermal capacity from 300 MW to 600 MW within the next five years, underscoring its commitment to bolstering the nation's renewable energy portfolio.

In addition to Mount Malinao, PGPC is actively evaluating other prospective geothermal resource areas situated on the main island of Luzon. These include sites in Kalinga, Daklan, Cagayan-Baua, and Labason, indicating a broad and strategic approach to expanding its geothermal footprint. The progress of the Mount Malinao exploration is particularly noteworthy as it directly supports the Philippine Department of Energy's overarching goal of achieving a minimum 50% renewable energy share in the total national power generation mix by the year 2040.

PGPC holds a distinguished position as a pioneering force in geothermal energy development within Southeast Asia. Its predecessor, the Philippine Geothermal, Inc. (PGI), established a legacy of innovation with the commissioning of the Makban Geothermal Power Plant in 1979, a landmark achievement in the region's renewable energy sector.

The Mount Malinao geothermal prospect, located within an active volcanic zone, is considered to possess substantial untapped geothermal energy reserves. The ongoing exploratory drilling endeavors are crucial for PGPC to meticulously assess critical subsurface parameters, including temperature gradients, pressure regimes, and geological formations. The data gleaned from these operations will be instrumental in determining the technical and economic viability of constructing a large-scale geothermal power plant.

The Philippines, strategically located along the Pacific Ring of Fire, boasts considerable geothermal energy potential, ranking as the fifth-largest geothermal power producer worldwide. The national government has articulated a strong commitment to expanding the utilization of renewable energy sources, with geothermal energy playing a pivotal role in achieving energy independence and sustainability targets.

PGPC has been a key player in the Philippine geothermal power industry, accumulating significant technical expertise and operational experience through its management of the Makban and Tiwi geothermal power plants. The company's proactive pursuit of new geothermal developments, exemplified by the Mount Malinao initiative, is central to its growth strategy and holds considerable promise for enhancing the Philippines' energy self-sufficiency and promoting environmentally responsible power generation.

The successful development of the 49 MW Mount Malinao Geothermal Power Plant is anticipated to yield significant benefits for the Albay region, including a more secure and reliable electricity supply and the potential for stimulating local economic growth. Furthermore, this project aligns with broader national objectives of reducing reliance on fossil fuels and mitigating greenhouse gas emissions, contributing to a more sustainable energy future for the Philippines.

Industry observers view PGPC's commencement of exploratory drilling at Mount Malinao as a crucial milestone in the Philippines' ongoing efforts to harness its abundant renewable energy resources. The results of the exploration phase and subsequent progress in the development of the power plant will be closely monitored by stakeholders in the energy sector and beyond.
