Geothermal power in Indonesia

Geothermal power in Indonesia is an increasingly significant source of renewable energy. As a result of its volcanic geology, it is often reported that Indonesia has 40% of the world's potential geothermal resources, estimated at 28,000 megawatts (MW).^[1]

With 2,356 MW of installed capacity as of year-end 2022, this puts Indonesia in second place in the world after the United States in utilizing geothermal power, superseding the Philippines.^[2] In 2007, geothermal energy represented 1.9% of the country's total energy supply and 3.7% of its electric power.^[3]

At the 2010 World Geothermal Congress in Bali, President Susilo Bambang Yudhoyono announced a plan to build 44 new geothermal plants by 2014, more than tripling capacity to 4,000 MW. By 2025, Indonesia aims to produce more than 9,000 MW of geothermal power, becoming the world's leading geothermal energy producer.^[1] This would account for 5% of Indonesia's total energy needs.^[3]

A detailed report on the geothermal sector in Indonesia issued in 2015 by the Asian Development Bank and World Bank, Unlocking Indonesia's Geothermal Potential, indicated that reforms in key areas of policy were likely to be needed to stimulate sustained expansion in the sector.
