Hydro and geothermal to dominate Indonesia’s renewable energy mix until 2028

The Acting Director of PT PLN (Persero), Djoko R. Abumanan, said that the potential of renewable energy generation is spread throughout Indonesia, especially from hydropower and geothermal energy. “The portion of the biggest generation is indeed water and geothermal,” he told a local paper in July. PLN noted the new renewable energy mix (EBT) for generation until May 2019 had reached 13.42% with the largest portion being in hydro power. In more detail, until May 2019, the percentage of hydroelectric power plants (PLTA) operating reached 7.61%. Furthermore, in a row, the share of geothermal power plants (PLTP) reached 4.95%, 0.59% diesel power plants, and other EBTs such as solar, wind and 0.27 percent biomass. In addition to having the largest share, hydropower also experienced the largest increase in realization from the 2018 condition, which rose 1.24 percent. In the medium term, hydropower will still be the biggest energy mix target in the 2019-2028 Electric Power Supply Business Plan (RUPTL). In the 2019-2028 period, it is targeted that there will be an additional renewable energy generating capacity of 16.76 GW. From the planned addition, hydropower dominates with a portion of 48 percent. The second position is occupied by geothermal energy at 27 percent. The rest, micro-hydro power plants (PLTM) 9 percent, solar power plants (PLTS) 6 percent, wind power power plants (PLTB) 5 percent, garbage power plants (PLTSa) 5 percent, and ocean currents (PLTAL) ) 0.04 percent. Comment: this would require 4,000+ MW of geothermal power generation capacity to be added in the next 7-8 years, which seems to be ambitious but not impossible, but only if roadblocks such as PPA negotiations and contracting can be utterly improved. How Indonesia can push geothermal development will be extensively covered at the upcoming Indonesia International Geothermal Convention and Exhibition (IIGCE), August 13-15, 2019. Source: Bisnis.com
