The National Geothermal Association of the Philippines (NGAP) is set to formalize its proposal this year, with its request for Feed-In Tariff (FIT) rates to apply to unconventional geothermal resources, an official said in an interview.
“What we want is for the FIT to apply to other geothermal resources, and new, developmental geothermal technologies like the enhanced geothermal system (EGS), hot sedimentary aquifer (HSA) and acid fluid utilization. These technologies are currently economically non-feasible given the higher development costs,” NGAP President Bong B. Bayon said.
Mr. Bayon said that with higher development costs, developers tend not to look at the unconventional prospects, and instead concentrate on the usual high-temperature ones.
The unconventional prospects, he said, include low-temperature and acidic areas. Currently, the country’s producing fields are all high-temperature areas, at around 280 degree Celsius.
