To reach the target of 23 percent (of mixed-energy) in 2025, we would need 14 gigawatt of renewable energy power generation.
Jakarta (ANTARA) - Indonesia would need to generate at least 14 gigawatt (GW) of renewable energy to increase its share to 23 percent in the national energy mix by 2025, a think tank has said.

Renewable energy's share in the national energy mix is currently recorded at just 11.2 percent, far below the target of 23 percent, executive director of the Institute for Essential Services Reform (IESR), Fabby Tumiwa, said during an online discussion here on Tuesday.

"To reach the target of 23 percent (of mixed-energy) in 2025, we would need 14 GW of renewable energy power generation," Tumiwa said.

Indonesia has abundant green energy resources that could be optimized to reach the target, he added.

According to Tumiwa, solar energy has the highest potential among other energy sources as the technology could be developed quickly from the smallest household scale to industry scale.

"Therefore PLTS (solar power generators) could become the government's priority to reach the target," he said.

The government has adopted three approaches for developing PLTS—installation of large-scale power generators to produce 4.68 GW of electricity; floating PLTS in 271 lakes and dams to produce 26.65 GW of electricity; and rooftop PLTS to produce 3.61 GW of electricity.

In addition to solar energy, the government also has chalked up several other strategies to increase renewable energy's proportion in the national energy mix, including the development of a smart grid, grid code revision, and the issuance of a Presidential Regulation on renewable energy.

Data released by the government in 2020 pegged Indonesia's renewable energy capacity at 10,467 megawatt (MW), comprising 3.6 MW of hybrid energy, 154.4 MW of wind-generated energy, 153.8 MW of solar energy, 1,903.5 MW of biomass energy, 2,130.7 MW of geothermal energy, and 6,121 MW of hydroelectric power.

The government is aiming to reach 24 thousand MW of installed capacity of environment-friendly electricity by 2025 and 38 thousand MW by 2035.
