| Abstract |
The installed capacity of geothermal power plant in Indonesia has reached 1,925 MWe and become the second to the USA in the world. Government of Indonesia through RUEN (Rencana Umum Energi Nasional) set target for 7,214 MWe geothermal plant installed capacity in 2025 to ensure that Indonesia’s energy mix will be more independent from the volatile fossil fuel price. With the current rate, it will be a challenge for geothermal stakeholders to achieve this target. If looked back to the first installed capacity in 1983, the rate of development is very slow. If it is compared to the developed country, such as Turkey and Kenya, the rate is still low. Turkey in particular installs around 1,000 MWe in 10 years. This paper reviewed the energy mix and market of the top 5 geothermal countries, their typical geothermal system, current development strategy, and their roadmaps for development. The challenges for each country geothermal energy development was also discussed. Kenya and Turkey geothermal energy development are also discussed even though they are not in the top 5. To conclude, this study discussed what other countries do differently with Indonesia regarding the policy or technology, and what can Indonesia learns from them in order to accelerate and increase the geothermal energy portion in its energy mix. |
