An Update on the Philippine Geothermal Resource Estimates

Abstract

An updated estimates was made for the Philippine geothermal reserves and resources using stored-heat method with Monte Carlo simulation. The results of the computation suggests that the Philippine geothermal resources ranges from 1,028MWe (P90) to 4,064MWe (P10) with 2,152 (P50) as the best estimate. Likewise, this paper has counted approximately 136 geothermal areas that includes the 8 areas currently in commercial operation. This paper showed significant increase in the resources estimates compared to the 2010 values. The reason can be linked to additional data that has been generated for the past decade. With the onset of enabling policies, advances in technology, and DOEs continuing initiative of preliminary surveys of the country’s geothermal resources, the further development of the remaining geothermal resources may now be realized in the coming years.
