History of development and commissioning
The Mak-Ban Geothermal Power Plant, a 458-MW facility operated by Aboitiz Power, traces its operational origins to the late 1970s in the Philippines. The complex, situated across the provinces of Laguna and Batangas, was commissioned in 1979. This initial phase of development was executed by Chevron Geothermal Philippine Holdings, Inc., which served as the primary developer under a contractual agreement with the National Power Corporation (NPC). The involvement of Chevron marked a significant period in Philippine energy infrastructure, establishing the Mak-Ban site as a cornerstone of the nation’s geothermal capacity. The 1979 commissioning date signifies the entry of the first units into service, laying the groundwork for the expanded complex that would follow in subsequent decades. The partnership between Chevron and the NPC was instrumental in harnessing the geothermal resources of the region, contributing to the energy mix of the Luzon grid. The facility’s establishment in 1979 positioned it as one of the earlier large-scale geothermal installations in the country, following the pioneering Tiwi Geothermal Power Plant. The Tiwi facility, located in Albay, had previously demonstrated the viability of geothermal energy in the Philippines, providing a technical and operational model for the Mak-Ban development. The success at Tiwi encouraged the expansion of geothermal exploration and construction in the neighboring provinces of Laguna and Batangas, leading to the establishment of the Mak-Ban complex. The 1979 commissioning by Chevron Geothermal Philippine Holdings, Inc. under contract with the National Power Corporation (NPC) reflects the strategic approach taken to develop the country’s geothermal potential during that era. The facility’s location in Laguna and Batangas allowed for the utilization of the geothermal fields associated with the Makiling and Banahaw volcanic ranges. This geographic positioning was critical to the plant’s efficiency and output, which has since reached a total capacity of 458 MW.

Privatization and ownership transition
The ownership structure of the Mak-Ban Geothermal Power Plant underwent a significant transformation in the mid-2000s, shifting from direct government control to private sector management. This transition was part of a broader strategy by the Philippine government to streamline energy assets and attract investment through the Philippine State Assets Management Corporation (PSALM). The decision to sell the facility marked a pivotal moment in the operational history of the 458-MW complex located across Laguna and Batangas.
PSALM Sale Process
In 2005, the Philippine government formally initiated the privatization process for the Mak-Ban facility. The asset was placed under the management of PSALM, which served as the vehicle for the sale. This move was designed to separate the generation assets from the traditional holding company, allowing for more focused operational efficiency and financial structuring. The sale process involved evaluating the long-term value of the geothermal fields and the associated power station infrastructure.
Completion of the Sale
The privatization transaction was completed in 2008. This year marked the official transfer of ownership rights, finalizing the deal that had been structured through PSALM. The completion of the sale in 2008 provided certainty to the investors and laid the groundwork for subsequent corporate restructuring within the energy sector. The facility remained operational during this transition, ensuring continuity in power generation for the grid.
Aboitiz Power Takeover
Following the completion of the sale, the operational control of the Mak-Ban Geothermal Power Plant was taken over by Aboitiz Power. This transition occurred in 2009, when Aboitiz Power assumed management through its subsidiary, AP Renewables Inc. Aboitiz Power, a major player in the Philippine energy market, integrated the 458-MW complex into its growing portfolio of renewable energy assets. Under the stewardship of AP Renewables Inc., the plant continued to operate as a key component of the country's geothermal capacity, leveraging the established infrastructure in the Makiling-Banahaw region.

How does geothermal energy work in the Philippines?
The Mak-Ban Geothermal Power Plant operates within the Philippines' broader geothermal infrastructure, leveraging the archipelago's position along the Pacific Ring of Fire. This tectonic setting provides abundant high-enthalpy resources, where underground water is heated by magma and hot rocks, creating steam that drives turbines. The Mak-Ban complex, located across Laguna and Batangas, is a primary example of this resource utilization. It is operated by Aboitiz Power and has a total installed capacity of 458 MW. The plant was commissioned in 1979, marking it as a mature asset in the national grid. Its operational status remains active, contributing significantly to the country's baseload power supply.
Geothermal Technology and Resource Type
The technology employed at Mak-Ban is consistent with standard dry steam and flash steam systems used in high-temperature geothermal fields. In these systems, hot water and steam are extracted from deep reservoirs. The steam drives turbine generators, converting thermal energy into electrical energy. The Mak-Ban field specifically taps into the volcanic systems of Mount Makiling and Mount Banahaw. These volcanoes provide the necessary heat source for the geothermal fluid. The plant's 458 MW capacity is derived from multiple wells and units distributed across the two provinces. This configuration allows for efficient heat extraction and power generation. The use of geothermal energy in the Philippines is characterized by its reliability and low carbon footprint compared to fossil fuel alternatives. The Mak-Ban plant exemplifies this by providing consistent power output, independent of daily weather patterns that affect solar and wind energy.
