Tiwi Geothermal Complex
# Tiwi Geothermal Complex

The Tiwi Geothermal Power Plant is a 330-MW geothermal power station in Tiwi, Albay, Philippines.

## History

The Commission on Volcanology conducted exploration on the Tiwi geothermal field from 1964 to 1968.

The Philippine government in early 1971 invited the Union Oil Company of California (Unocal)to form the Philippine Geothermal, Inc. (PGI) which is intended as a joint venture for the exploration and development of geothermal energy. A service contract was made with the state-owned National Power Corporation (NPC) on September 10, 1971. PGI provided technical expertise as well as partially the exploration and further development of the Tiwi field. NPC would build and operate the geothermal power plants itself. The first two units were commissioned in the 1979. Units 3 to 6 would be commissioned from 1980 to 1982.

In January 2023, an new binary cycle power plant within the Tiwi Geothermal Power Plant broke ground. It will add 17-MW capacity to the existing geothermal complex.

## Facilities

The Tiwi Geothermal Field has four geographic areas namely Naglagbong, Kapipihan, Matalibong, and Bariis. It has six units.
