The Philippine geothermal industry is described as a mature sector operating in a developed private investment market. Geothermal investments in the country will be driven by the combination of a strong clean energy supply imperative, increasingly liberalized energy sector, achievable capacity targets and a relatively stable regulatory framework with appropriate pricing or fiscal incentives, and off-take mechanism. Some of the remaining undeveloped geothermal resources pose special technical challenges, requiring development or adaptation of “emerging technologies” such as binary-cycle generation, ground source heat pumps, and corrosion-resistant alloys. With an appropriately structured feed-in tariff rate that will provide guaranteed payment to investors through a universal charge, these acidic and lower enthalpy resources can be developed to generate electricity. In order to address the barriers related to costs and resource exploration risks faced by geothermal energy developers, the National Geothermal Association of the Philippines calls for the coverage under the FIT program of geothermal emerging technologies currently not commercially viable under existing market and pricing structures.
