APRI and PGPC commit to further develop clean geothermal energy

Leene Camo | August 24, 2018

AP Renewables (APRI) and Philippine Geothermal Production Company(PGPC) have signed a Geothermal Resources Supply and Services Agreement (GRSSA) for the supply of steam and drilling of new production wells in the Tiwi and MakBan Geothermal Complex. The agreement highlights their joint commitment to continue the development of clean geothermal energy in the country, ensuring the long-term operations of these two renewable power plant facilities.

APRI operates the 458-MW MakBan Geothermal Power Plants that straddle the provinces of Batangas and Laguna, as well as the 289-MW Tiwi Geothermal Power Plants in Albay. PGPC, the pioneer in the commercial development of geothermal energy in Southeast Asia, is the steam fields operator and geothermal resource provider to APRI Tiwi and APRI MakBan.

The GRSSA — signed by both parties on August 24, 2018 — will see PGPC drilling 12 new production wells over a six-year period to increase steam availability for the power plant facilities by about 20%. The agreement also ensures a more competitive fuel pricing in the long term.

APRI is committed to deliver reliable and renewable power to our customers. This agreement secures the continued viability of the power plant facilities, allowing us to deliver that commitment. For three years now, the Philippines has been ranked number 1 in environmental sustainability in the World Energy Council’s (WEC) Energy Trilemma report because we continue to maximize the potential of RE in the country, we hope to continue that momentum.

President and COO



Renewable baseload energy is critical for the Philippines to power its economic growth. The sustainable operation of the geothermal steam field is our way of supporting the country’s long-term energy needs through the supply of reliable, clean, and indigenous energy resources.

First commissioned in 1979, the Tiwi-MakBan Geothermal Complex is one of the biggest geothermal facilities in the country and the region. PGPC has since operated the steam field facilities. AboitizPower took over the operations and management of the power plant facilities from the National Power Corporation in 2009.
