Philippines starts hunt for P788 billion geothermal power wealth

The Philippines is seeking to unlock approximately P788 billion (US$12.6 billion) worth of untapped geothermal energy potential to regain its global standing in geothermal power.

Philippine Geothermal Revival Requires Execution and Grid Capacity

Reclaiming a leading global position in geothermal energy depends entirely on turning paper resource estimates into active grid capacity. Unlocking P788 billion in untapped potential requires substantial upfront capital deployment for exploration and drilling. The primary execution barrier in high-temperature geothermal projects rests on early stage exploration risks and delayed transmission infrastructure connections, which can tie up capital for years before generation starts.

Energy regulators and private operators must streamline site concessions and align baseline power purchase terms with grid expansion schedules. Investors should monitor whether policy support translates into expedited resource testing permits and clear off-take agreements over the next development cycle.

For investment committees, evaluating Philippine energy plays requires discounting headline potential and focusing strictly on projects with secured drilling rights and clear grid access.
