PT Perusahaan Listrik Negara (PLN), Indonesia's state-owned electricity company, had a total installed power generation capacity of 44,939.88 megawatts (MW) at the end of 2022.
The following details the installed capacity of PLN's power plants by type:
* Coal-fired power plants (PLTU): 20,418.5 MW (45.44% of total installed capacity)
* Combined cycle power plants (PLTGU): 11,764.85 MW (26.18%)
* Diesel power plants (PLTD): 3,564.63 MW (7.93%)
* Hydroelectric power plants (PLTA): 3,516.51 MW (7.82%)
* Gas-fired power plants (PLTG): 2,796.82 MW (6.22%)
* Gas engine power plants (PLTMG): 2,189.23 MW (4.87%)
* Geothermal power plants (PLTP): 579.26 MW (1.29%)
* Micro-hydro power plants (PLTMH): 46.12 MW (0.10%)
* Mini-hydro power plants (PLTM): 34.35 MW (0.08%)
* Solar power plants (PLTS): 28.62 MW (0.06%)
* Biomass power plants (PLTBM): 0.52 MW (0.001%)
* Wind power plants (PLTB): 0.47 MW (0.001%)
The data shows that PLN's fossil fuel-based power plants generally have a larger installed capacity than new and renewable energy (NRE) power plants.
Fossil fuel power plants include PLTU, PLTGU, PLTD, PLTG, and PLTMG. NRE power plants include PLTA, PLTP, PLTMH, PLTM, PLTS, PLTBM, and PLTB.
Although their share is still small, PLN has stated it will continue to strive to accelerate the development of NRE power plants.
One of PLN's efforts involves a collaboration with China Communications Construction Dredging Co. Ltd. (CCCC) for NRE development. The agreement was signed at the end of May 2023.
"The collaboration between PLN and CCCC is expected to accelerate the development of NRE power plants. This will enable Indonesia to further accelerate its energy transition," said PLN President Director Darmawan Prasodjo in a press release (May 21, 2023).
"This cooperation agreement can increase investor confidence. Through a solid partnership between PLN and CCCC, it is also hoped that economic relations between China and Indonesia can be strengthened," he continued.
