According to PLN's report, in 2021 Indonesia had 421 renewable energy power plants with a total installed capacity of 4,189 megawatts (MW).
This figure represents only 6.5% of the total installed capacity of national power plants, which reached 64,553 MW last year.
The following details the installed capacity of Indonesia's renewable energy power plants in 2021, ordered from largest to smallest:
* Hydroelectric Power Plants (PLTA): 3,504.02 MW
* Geothermal Power Plants (PLTP): 579.26 MW
* Microhydro Power Plants (PLTMH): 45.62 MW
* Minihydro Power Plants (PLTM): 37.68 MW
* Solar Power Plants (PLTS): 21.34 MW
* Biomass Power Plants (PLTBm): 0.5 MW
* Wind Power Plants (PLTB): 0.47 MW
According to the International Renewable Energy Agency (IRENA), the installed capacity of renewable energy power plants in Indonesia is still very minimal, namely only 0.3% of the total potential. IRENA assesses that the main obstacle in this sector is a lack of investment.
"A significant obstacle in driving Indonesia's energy transition is funding and investment. Financing sources need to be expanded and local financing capacity needs to be improved," said IRENA in its *Indonesia Energy Transition Outlook* report released in October 2022.
Regarding this, Minister of State-Owned Enterprises Erick Thohir plans to develop a financing strategy for renewable energy through a merger of Pertamina, PLN, and Star Energy.
"We have three geothermal companies in Pertamina, PLN, and another one, Star Energy, under the Ministry of Finance. I want to merge these into one unit. We want to be like Pertamina Geothermal Energy so that we have access to funding through going public," said Erick at the *Special Event Road to G20* at the IPB International Convention Center, Bogor, West Java, Tuesday (25/10/2022).
