The generation of electric power in the Philippines is aimed to attain self-reliance through availment of indigenous energy resources to meet the needs of industrial growth. The Philippines has several exploitable geothermal fields located all over the country. The Geothermal areas presently in various stages of exploration and development are of such
magnitude that they can be relied on to meet a significant portion of the country's power need.

Large scale geothermal energy for electric power generation was put onto operation with the inauguration of two 55-MW geothermal generating units at Tiwi, Albay in Southern Luzon in 1979. Another two 55-MW units were added to the Luzon Grid in the same year from Makiling-
Banahaw field about 70 kilometers south of Manila. Last year a total of 220-MW power was added from the same areas. This brought to 446-MW of installed generating capacity from geothermal energy with 3-MW contributed by the Tongonan Geothermal pilot plant in Tongonan, Leyte, Central Philippines and another 3-MW from Palimpinon-Dauin field in
Southern Negros in operation since 1977 and 1980, respectively.

The technical and economic acceptability of electric power derived from geothermal energy is competitive with other sources of energy and is a viable source of baseload electric power.

Geothermal energy resource development is being accelerated with a target for development of six fields by 1985 by adding Manito and Daklan fields to the currently developed and producing geothermal areas.
