[1] The Philippines is one of the world's top producers of geothermal power, owing to its location along the Ring of Fire zone of Pacific volcanoes.
[6] Early statistics from the Institute for Green Resources and Environment stated that Philippine geothermal energy provides 16% of the country's electricity.
[8] More recent statistics from the IGA show that combined energy from the nation's six geothermal fields, located in the islands of Luzon, Leyte, Negros and Mindanao, still accounts for approximately 17% of the country's electricity generation.
[4] Larger-scale commercial production of geothermal power began in 1979 with the commissioning of a 110-megawatt plant at Tiwi field in Albay province.
[13] On October 20, 2020, however, a modification of the implementing rules and regulations of the Renewable Energy Act of 2008 allowed an exception in the case of financial or technical agreements covering the large-scale exploration, development, and utilization of such resources, effectively allowing 100% ownership of any geothermal projects whose initial investment costs are over $50 million.
