Geothermal power generation in Indonesia, a country within the ring of fire: Current status, future development and policy

In the current situation, Indonesia has aggressive plans for future development geothermal power plant. In 2005 geothermal roadmap target had been released to produce 9500 MW. However, this target then evaluated to more realistic to 7000 MW in 2025. Last year in 2016 additional of the 35 MW Kamojang unit-5, 40 MW of Lahendong 2 × 20 MW and 55 MW of Ulubelu unit-3 has been inaugurated. Furthermore, five more plants will be operated in Ulubelu, Lahendong and Sarulla, Karaha bodas and Lamut balai. To promote more development of geothermal energy, government has issued laws such as Law No. 21 of 2014 represents a change from the policy of Act No. 27 of 2003. An important point of revision is that geothermal power generation is no longer classed as a mining operation. The law also describes the price of geothermal energy in three different area divisions, each with a different benchmark price.
