Ecobiz.asia — Indonesia’s renewable energy capacity has reached 15.2 gigawatts (GW) as of the first half of 2025, with the total national generation capacity approaching 100 GW.
Director of Various New and Renewable Energy at the Ministry of Energy and Mineral Resources (ESDM), Andriah Feby Misna, stated that approximately 876 megawatts (MW) of additional renewable capacity was installed in the first half of 2025, primarily driven by large-scale hydropower projects, followed by solar and wind energy.
Feby highlighted that no wind power plants have reached commercial operation date (COD) this year, but expressed hope that existing wind projects in Sulawesi would soon be expanded due to the region’s significant wind energy potential.
“We have only tapped about one-thousandth of the total wind energy potential in Indonesia,” she said during the Indonesia Sustainable Energy Week Goes Regional 2025 event in Makassar, Wednesday (29/10/2025).
The government is accelerating renewable energy development under the Electricity Supply Business Plan (RUPTL) 2025-2034, with a target of adding 46.2 GW of renewable capacity over the next decade, or an average of 4.6–5 GW annually.
“Achieving these targets is one of our biggest challenges,” Feby added.
Sulawesi plays a pivotal role in Indonesia’s clean energy transition, contributing 2.14 GW of renewable energy capacity, or approximately 14% of the nation’s total, with hydropower and wind energy as the dominant sources.
The Ministry aims to expand the use of solar, geothermal, and biomass energy in Sulawesi to further support national decarbonization efforts. Feby pointed out that the region’s growing smelter industries would drive increased energy demand, providing an opportunity to integrate renewable power into industrial systems.
“Sulawesi is an ideal location to demonstrate how renewable energy can help decarbonize power systems, particularly in hard-to-abate sectors like smelting,” she said.
With the expansion of PLN’s Sulawesi power grid and the development of smart grid infrastructure, the region is set to develop an additional 7.7 GW of renewable capacity under the RUPTL 2025–2034, equating to approximately 770 MW annually. ***
